Dorsal raphe to basolateral amygdala corticotropin-releasing factor circuit regulates cocaine-memory reconsolidation.

Environmental stimuli elicit drug craving and relapse in cocaine users by triggering the retrieval of strong cocaine-related contextual memories. Retrieval can also destabilize drug memories, requiring reconsolidation, a protein synthesis-dependent storage process, to maintain memory strength. Corticotropin-releasing factor (CRF) signaling in the basolateral amygdala (BLA) is necessary for cocaine-memory reconsolidation. We have hypothesized that a critical source of CRF in the BLA is the dorsal raphe nucleus (DR) based on its neurochemistry, anatomical connectivity, and requisite involvement in cocaine-memory reconsolidation. To test this hypothesis, male and female Sprague-Dawley rats received adeno-associated viruses to express Gi-coupled designer receptors exclusively activated by designer drugs (DREADDs) selectively in CRF neurons of the DR and injection cannulae directed at the BLA. The rats were trained to self-administer cocaine in a distinct environmental context then received extinction training in a different context. Next, they were briefly re-exposed to the cocaine-predictive context to destabilize (reactivate) cocaine memories. Intra-BLA infusions of the DREADD agonist deschloroclozapine (DCZ; 0.1 mM, 0.5 µL/hemisphere) immediately after memory reactivation attenuated cocaine-memory strength, relative to vehicle infusion. This was indicated by a selective, DCZ-induced and memory reactivation-dependent decrease in drug-seeking behavior in the cocaine-predictive context in DREADD-expressing males and females at test compared to respective controls. Notably, BLA-projecting DR CRF neurons that exhibited increased c-Fos expression during memory reconsolidation co-expressed the glutamatergic neuronal marker, vesicular glutamate transporter 3. Together, these findings suggest that the DRCRF → BLA circuit is engaged to maintain cocaine-memory strength after memory destabilization, and this phenomenon may be mediated by DR CRF and/or glutamate release in the BLA.

Pharmacological characterization of prostaglandin E2 EP2 and EP4 receptors in male rat locus coeruleus neurons ex vivo

The inflammatory mediator prostaglandin E2 (PGE2) binds to Gs-coupled EP2 and EP4 receptors. These receptors are located in the locus coeruleus (LC), the principal noradrenergic nucleus in the brain, but their functional role remains unknown. In this study, the PGE2 EP2 and EP4 receptors in LC cells from male rat brain slices were pharmacologically characterized by single-unit extracellular electrophysiology. The EP2 receptor agonists butaprost (0.01–10 μM) and treprostinil (0.03–10 µM) and the EP4 receptor agonists rivenprost (0.01 nM–1 µM) and TCS2510 (0.20 nM–2 µM) increased the firing rate of LC neurons in a concentration-dependent manner. The EP2 receptor antagonist PF-04418948 (10 nM) hindered the excitatory effect of butaprost and treprostinil while the EP4 receptor antagonist L-161,982 (30 and 300 nM) blocked the excitatory effect caused by rivenprost and TCS2510. The effects of butaprost and rivenprost were prevented by extracellular sodium replacement but were not modified by the protein kinase A (PKA) activator 8-Br-cAMP (1 mM) or the inhibitor H-89 (10 μM). However, the Gβγ subunit blocker gallein (20 μM) hindered the stimulatory effect of butaprost while the Gαs subunit inhibitor NF449 (10 µM) prevented that of rivenprost. Finally, rivenprost-induced stimulation (30 nM) was not occluded by butaprost (1 µM).In conclusion, activation of EP2 and EP4 receptors excites LC noradrenergic neurons through sodium-dependent currents via different G protein subunits in male rat brain slices. EP2 and EP4 in the LC may constitute pharmacological targets for the treatment of pain, fever, drug addiction, anxiety and neuroinflammatory diseases.

Nonsedating anxiolytics.

Anxiety disorders are the most prevalent psychiatric pathology with substantial cost to society, but the existing treatments are often inadequate. This has rekindled the interest in the GABAA-receptor (GABAAR) positive allosteric modulator (PAM) compounds, which have a long history in treatment of anxiety beginning with diazepam, chlordiazepoxide, and alprazolam. While the GABAAR PAMs possess remarkable anxiolytic efficacy, they have fallen out of favor due to a host of adverse effects including sedation, motor impairment, addictive potential and tolerance development. A substantial effort was thus devoted to the design of GABAAR PAMs as anxiolytics with reduced sedative liabilities. Several non-benzodiazepine (BZD) GABAAPAMs progressed to clinical trials (bretazenil, abecarnil, alpidem, and ocinaplon) with alpidem obtaining regulatory approval as anxiolytic, but later withdrawn from market due to hepatotoxicity. Advances in molecular biology gave birth to a host of subtype selective GABAAR-PAMs which suffered from signs of sedation and motor impairment and only three compounds progressed to proof-of-concept studies (TPA-023, AZD7325 and PF-06372865). TPA-023 was terminated due to toxicity in preclinical species while AZD7325 and PF-06372865 did not achieve efficacy endpoints in patients. We highlight a new compound, KRM-II-81, that is an imidazodiazepine selective for GABAAR containing α2/3 and β3 proteins. In preclinical studies KRM-II-81 produced anxiolytic-like effects but with minimal sedation, respiratory depression, and abuse liability. Thus, KRM-II-81 is a newly discovered, non- BZD anxiolytic compound, which targets a selective population of GABAAR for improved therapeutic gain and reduced side effects.

The Impact of Methamphetamine on Liver Injury in Iraqi Male Addicts

Methamphetamine (METH) is a powerful stimulant that affects neurochemical processes controlling heart rate, appetite, blood pressure, body temperature, and wakefulness, making it highly susceptible to abuse. Liver enzymes such as ALT, AST, ALP, and GGT are crucial for liver function. Albumin, a protein synthesized by healthy liver cells, serves as an indicator of chronic liver disease. Additionally, hepatocytes produce bile acids, which are essential for the secretion of bile salts into the bile canaliculi. Disruption in this secretion results in the accumulation of bile salts in the canaliculi, leading to intrahepatic cholestasis. METH-induced liver toxicity involves disruptions in hepatic metabolism, oxidative stress, and increased body temperature, affecting cellular processes such as cell division and the cell cycle and potentially accelerating liver cell apoptosis. The study explores the link between liver toxicity and hepatocyte damage in Iraqi males suffering from addiction. This is a case-control study, conducted at Ibn-Rushed Psychiatric Hospital in Baghdad from July 2023 to February 2024, involved 196 males, with addiction durations exceeding 24 months with varying degrees of methamphetamine (METH) addiction. The study included 187 healthy male controls with no history of drug addiction. Participants were aged 18 to 40 years. Diagnosis was confirmed using a drug test screening card administered by a specialist. The study included liver function tests (ALT, AST, ALP, and GGT), total bilirubin, and albumin concentration assessments. Significant differences were observed between the addicts and controls, particularly a marked decrease in serum albumin concentration in the addicted males. The ROC curve classification model at various thresholds demonstrated that liver enzymes, especially ALT, ALP, and GGT, exhibited increased sensitivity to METH addiction. A histopathological examination was conducted on a deceased 38-year-old male who had a six-year history of chronic amphetamine addiction to confirm liver injury and the resulting elevation of liver enzymes. The findings of this study indicate that METH greatly affects liver function, suggested to the importance of following a preventative measures and effective treatment approaches for monitoring METH addiction progress.

The influence of social media on adolescent mental health and substance abuse patterns

Adolescents' widespread use of social media has become a serious public health issue, especially considering its effects on substance abuse and mental health. The aim of this review is to examine the complex relationship between the use of social media, mental health issues, and the rise in substance abuse among teenagers. An overview of social media engagement trends is given at the start, emphasising that teenagers are among the most frequent users and that platforms such as Instagram, TikTok, and Snapchat are essential to their social lives. According to recent studies, high social media use has been linked to a rise in mental health conditions, such as anxiety, depression, and low self-esteem. The prevalent behaviours of social comparison, cyberbullying, and validation-seeking in online interactions exacerbate mental health challenges. The review also explored the patterns of substance abuse among adolescents, with particular attention to the use of alcohol, tobacco, and illegal narcotics. Peer pressure, family dynamics, early substance exposure, and other factors have been identified as contributing factors to substance misuse. A critical analysis is conducted on the function that social media plays in normalising substance use, since media portrayals of substance use can glamourise these behaviours and make them seem socially acceptable to impressionable teens. The ways in which peer pressure and heightened stress are two of the methods through which social media impact substance abuse are examined, offering a thorough grasp of the difficulties that young people today face. The urgent need for multifaceted interventions that address social media use and mental health education is emphasised in the review's conclusion. Along with programs to promote digital literacy and ethical social media usage, recommendations are made for parents, schools, and policymakers to reduce the risks associated with social media use. The results highlight the need for additional investigation into the complex interactions among social media, mental health, and substance addiction and support cooperative endeavours aimed at safeguarding and enabling young people in the digital age.

In Case You Haven't Heard…

National Institute on Drug Abuse director Nora Volkow, M.D. published a blog last week calling for community involvement in addiction science, and this means “[i]ncluding people with experience of substance use and addiction in the scientific workforce — and making sure they feel safe and recognized as valuable members of the research team…” Their perspectives, she wrote, “are invaluable in making sure that the right research questions are asked.” For the blog, go to https://nida.nih.gov/about‐nida/noras‐blog/2024/11/improving‐community‐engagement‐in‐addiction‐science

Reward deprivation is associated with elevated alcohol demand in emerging adults.

Policies vary substantially in terms of providing sources of psychosocial enrichment. Behavioral economic models of substance use and addiction emphasize that deficits in access to substance-free sources of reward increase substance reinforcing value and risk for addiction. The current study used an alcohol demand curve approach to test the hypothesis that various indices of reward deprivation would be associated with elevated alcohol reinforcing efficacy. We examined associations between alcohol demand indices and several facets of reward deprivation in a sample of young adults (N = 1,331; ages 19-25 years) recruited from the United States and Canada who reported recent binge drinking. Additionally, we created an index of cumulative reward deprivation that integrated the various reward facets and examined its association with alcohol demand intensity and maximum expenditure on alcohol. Our findings indicate that reward deprivation is associated with elevated alcohol demand and provide support for alcohol prevention and intervention approaches that emphasize environmental enrichment.

Enhancing the drug addiction treatment service by introducing a new residential treatment model in the Philippines: A qualitative study.

There is an increased demand for quality treatment and rehabilitation services for people who use drugs (PWUDs) in the Philippines. In response, the Philippines Government's Department of Health (DOH) has established a new residential treatment model, Intensive Treatment and Rehabilitation Program for Residential Treatment and Rehabilitation Centers (INTREPRET), and integrated it into the existing treatment service platform of 21 DOH-owned Treatment and Rehabilitation Centers (TRCs). We conducted a qualitative study to identify the changes engendered by the implementation of this treatment model. Data were collected through individual face-to-face interviews. We interviewed purposefully selected 29 patients and 35 facilitators of INTREPRET group sessions in seven TRCs. We transcribed the interview records and organized the narrative information into key themes using thematic analysis during the coding process. The changes perceived by the study participants included the attitude and behavior of patients, attitude and competency of facilitators, relationship between facilitators and patients, treatment planning and review process, efficient and standardized treatment services, and monitoring mechanisms of the patient's recovery process. Participants also noted challenges in INTREPRET implementation, including family participation in therapy sessions, lack of facilitators, securing a conducive place for conducting sessions, and reproducing workbooks. The results imply that the introduction of INTREPRET could improve treatment service quality and the effectiveness of treatment, which were primarily associated with behavioral changes in patients, improved relationship between patients and facilitators, and INTREPRET's alignment with key international treatment standards. However, despite the positive changes perceived by the participants, certain challenges pertaining to family participation in therapy sessions and the lack of resources were identified. These criticisms must be addressed by DOH, along with an integration of INTREPRET into its policy and strategic framework, to ensure the effectiveness and sustainability of the new treatment model.

E-Cigarette Addiction in Adolescents-How Do We Get Them to Stop?

E-cigarette use in adolescents is increasing and the addictive potential of these devices is well recognised. Most health authorities have no E-cigarette cessation programmes. We reviewed randomised control trials evaluating prevention strategies for adolescent E-cigarette use and identified any successful components. Search terms were created in accordance with the main objective (vaping/E-cigarette use prevention/cessation/adolescents). Search was conducted via Ovid MedLine for English-language randomised control trials published from 2020 to 2023 containing keywords relating to adolescent E-cigarette use. Seven U.S. studies were included in the review. We established common themes of qualitative outcomes and identification of successful components of prevention programmes. Interventions showed significant improvement in general knowledge and perceived risk of E-cigarettes, and lower risk of using other tobacco products. Other consequences showed lower susceptibility to vaping uptake and higher abstinence rates although future studies are required to see if these were sustained long-term. Focus groups aid development of cessation and prevention campaigns. Messages should be digital and relatable. Messages should contain health "harm" warnings. Furthermore, support services should be well-signposted for adolescents. Social media is a low-cost and important tool to halt teenage E-cigarette addiction.

Results of surgical treatment of infective endocarditis complicated by acute heart failure

Objective. To evaluate the results of surgical treatment of infective endocarditis complicated by acute heart failure. Materials and methods. The clinical data of 72 patients with infective endocarditis complicated by preoperative acute heart failure who underwent cardiac surgery at the Amosov National Institute of Cardiovascular Surgery of the National Academy of Medical Sciences of Ukraine from 01.01.2019 to 30.12.2022 were studied. All patients were assigned to functional class IV according to the functional classification of the New York Heart Association. Results. The average duration of infective endocarditis from its first signs (hyperthermia above 38 °C) to diagnosis was 2 months (2; 4 months). Among the causes of infective endocarditis, bronchopulmonary diseases dominated – 24 (33.3%) observations, general surgical interventions – 7 (9.7%) and hospital infection – 7 (9.7%). Urologic surgical interventions caused the development of infective endocarditis in 6 (8.3%) patients, hypothermia in 4 (5.6%), drug addiction in 4 (5.6%), and dental procedures in 1 (1.4%) patient. In 19 (26.4%) patients, the causes of infective endocarditis were not established. In 62 (86.1%) patients, a multi–valve correction was performed, and in 10 (13.9%) – a single–valve correction. The most common were two main options: aortic valve prosthetics in combination with mitral and tricuspid valve surgery in 13 (18.1%) patients and mitral and tricuspid valve surgery in 14 (19.4%) patients. Surgical intervention for combined lesions of the valvular apparatus of the left and right heart was performed in 51 (70.8%) patients with infective endocarditis complicated by acute heart failure. Frequent intracardiac abscessing – in 20 (27.8%) patients with aortic valve lesions and in 9 (12.5%) patients with mitral valve lesions – indicated a high rate of extensive infection spread. Hospital mortality in the surgical treatment of infective endocarditis complicated by acute heart failure was 13.9%. 10 patients died. Conclusions. In 96.1% of patients with infective endocarditis complicated by preoperative acute heart failure, multivalve surgical correction was performed. In the initial acute heart failure in the setting of infective endocarditis, intracardiac abscessing was often recorded: 27.8% in aortic valve lesions and 12.5% in mitral valve lesions. Hospital mortality in the surgical treatment of infective endocarditis complicated by preoperative acute heart failure was 13.9%.

Grazing and food addiction: Associations between varied patterns of overconsumption and addictive-like eating.

Food addiction (FA) research has primarily concentrated on binge eating as a symptom of this condition. However, FA may encompass various overeating behaviours, including compulsive grazing - the repetitive consumption of small amounts of food with loss of control. This study extends our previous research by including a clinical sample to investigate whether compulsive grazing exists in a population with higher prevalence and severity of FA. It also examines whether weight or sex moderates the severity or frequency of FA. Adults between the ages of 20 and 50 years with obesity were recruited from a weight-management clinic (n=437). Participants completed an online questionnaire to assess various eating behaviours (binge eating, compulsive grazing, reward-based eating) and related personality measures (impulsivity, addictive personality traits). Multiple and logistic regression modelling were used with the Yale Food Addiction Scale symptom count and diagnosis as the dependent variables, respectively. A chi-square test of independence and an analysis of variance were used to determine sex differences. Compulsive grazing was a significant factor in FA diagnosis and symptom severity, confirming earlier work. Binge eating was a significant factor in FA symptom severity. Additionally, females from a weight-management clinic sample were more likely to receive an FA diagnosis than females from the general population. No sex differences were found in males or in the symptom score option for FA. These findings suggest that various compulsive overeating patterns encompass FA. Individuals with obesity and co-morbid FA may require specialized treatments, which may benefit from sex-specific differentiations.

Effects of sex and estrous cycle on extended-access oxycodone self-administration and cue-induced drug seeking behavior

IntroductionIncreasing evidence indicates that sex is a factor that impacts the abuse liability and relapse vulnerability of prescription opioids like oxycodone. However, while women are more likely than men to be prescribed and to use these drugs, the impact of sex and ovarian hormones on prescription opioid use and relapse vulnerability remains unclear. Accurately assessing these measures is complicated by the fact that chronic opioid exposure can lower ovarian hormone levels and cause cycle irregularities.MethodsAdult male and female Sprague–Dawley rats self-administered oxycodone (0.1 mg/kg/infusion) under extended-access conditions (6 h/day, 10 days) followed by forced abstinence. Separate groups of animals received cue-induced seeking tests in a drug-free state during early (1–2 days) or later periods of abstinence (43–45 days). To track estrous cycle stage, animals were regularly vaginally swabbed throughout the study.ResultsWe observed oxycodone-induced estrous cycle dysregulation in the majority (~60%) of the animals during both self-administration and the first month of abstinence. In animals whose cycles were not dysregulated, we found a reduction in oxycodone intake during estrus compared to all other cycle stages (non-estrus). We also found that males but not females showed a time-dependent intensification or incubation of cue-induced oxycodone craving over the first 6 weeks of abstinence. This sex difference was estrous cycle-dependent, driven by a selective reduction in drug seeking during estrus.DiscussionThese findings highlight the importance of tracking drug-induced estrous cyclicity and identify a clear impact of ovarian hormones on oxycodone taking and seeking behavior.

The Impact of Alcohol-Induced Epigenetic Modifications in the Treatment of Alcohol use Disorders.

Alcohol use disorders are responsible for 5.9% of all death annually and 5.1% of the global disease burden. It has been suggested that alcohol abuse can modify gene expression through epigenetic processes, namely DNA and histone methylation, histone acetylation, and microRNA expression. The alcohol influence on epigenetic mechanisms leads to molecular adaptation of a wide number of brain circuits, including the hypothalamus-hypophysis-adrenal axis, the prefrontal cortex, the mesolimbic-dopamine pathways and the endogenous opioid pathways. Epigenetic regulation represents an important level of alcohol-induced molecular adaptation in the brain. It has been demonstrated that acute and chronic alcohol exposure can induce opposite modifications in epigenetic mechanisms: acute alcohol exposure increases histone acetylation, decreases histone methylation and inhibits DNA methyltransferase activity, while chronic alcohol exposure induces hypermethylation of DNA. Some studies investigated the chromatin status during the withdrawal period and the craving period and showed that craving was associated with low methylation status, while the withdrawal period was associated with elevated activity of histone deacetylase and decreased histone acetylation. Given the effects exerted by ethanol consumption on epigenetic mechanisms, chromatin structure modifiers, such as histone deacetylase inhibitors and DNA methyltransferase inhibitors, might represent a new potential strategy to treat alcohol use disorder. Further investigations on molecular modifications induced by ethanol might be helpful to develop new therapies for alcoholism and drug addiction targeting epigenetic processes.

The Impact of COVID-19 pandemic on addictive behaviors: an integrative review

Addictive behaviors and their impacts have been widely explored. Going through a pandemic moment requires further research since crisis situations involve higher propensity to dependency. The aim of this integrative review was to identify studies that have been conducted so as to explore behaviors related to brain’s reward system in a pandemic period, which include substance addiction, internet addiction, gaming and other overusing behaviors. In order to accomplish our objective an integrative search was conducted in CAPES periodicals. Some inclusion and exclusion criteria were used to select the studies and in total (N=12) were explored independently. The results showed that there is an increasingly concern about health care systems, especially for those addicted to substances who need daily support, since addictions habits may have also increased. Behavioral addictions also increased and were exploited in some studies, especially those related to technologies, such as gaming and smartphone usage.

Shared orbitofrontal dynamics to a drug-themed movie track craving and recovery in heroin addiction.

Movies captivate groups of individuals (the audience), especially if they contain themes of common motivational interest to the group. In drug addiction, a key mechanism is maladaptive motivational salience attribution whereby drug cues outcompete other reinforcers within the same environment or context. We predicted that while watching a drug-themed movie, where cues for drugs and other stimuli share a continuous narrative context, fMRI responses in individuals with heroin use disorder (iHUD) will preferentially synchronize during drug scenes. Thirty inpatient iHUD (24 male) and 25 healthy controls (16 male) watched a drug-themed movie at baseline and at follow-up after 15 weeks. Results revealed such drug-biased synchronization in the orbitofrontal cortex (OFC), ventromedial and ventrolateral prefrontal cortex, and insula. After 15 weeks during ongoing inpatient treatment, there was a significant reduction in this drug-biased shared response in the OFC, which correlated with a concomitant reduction in dynamically-measured craving, suggesting synchronized OFC responses to a drug-themed movie as a neural marker of craving and recovery in iHUD.

The Role of Dopamine in Impulsivity and Substance Abuse: A Narrative Review

Substance use disorder (SUD), based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), is defined by symptoms caused by utilizing a substance that a person continues taking despite its negative effects. Impulsive decision making is commonly defined as a reduced ability to choose a delayed large reward instead of a small immediate reward. Dopamine has been implicated as a prominent neurotransmitter implicated in the development and pattern of addiction and impulsivity, especially in regard to substance use disorder. Discovery as a key player in the development of addiction dates to the 1950s, with a study performed by Olds and Milner on rats placed in a Skinner box. Their original discovery is part of the beginning of what would become the search into the main mechanistic source of addiction, and how exactly it works at a cellular, physiological, and psychological level. The dopaminergic pathways of our brains are well-studied. It is well established that most of the dopaminergic neurons of the brain are located in the ventral mid-brain and consists of four main pathways: mesocortical, mesolimbic, nigrostriatal, and tuberoinfundibular pathways. Dopamine acts various receptors, with dopamine (D) receptors 1, 2, and 3 playing a major role in motor function and receptors D1 and D2 playing a major role in reward. There are additional studies warranted, especially finding ways to manipulate the dopaminergic system to treat addiction disorders of all varieties. The focus of the present investigation is to delve into the current literature regarding dopamine and its clinical implications in substance use disorder and impulsive behavior.

Analgesic Efficacy of Transversus Abdominis Plane block vs Local Infiltration of Lignocaine and Bupivacaine in Post-operative Patients

Objective: To compare the effectiveness of Transversus Abdominis Plane (TAP) block vs Local Infiltration for pain management techniques in patients undergoing laparoscopic lower abdominal surgeries. Methodology: This cross-sectional study was conducted at the Department of Surgery, Lahore General Hospital, from March to May, 2024. It involved a total of 110 patients, divided into two groups of 55 each, between the ages of 20 to 60 years, diagnosed with indirect inguinal hernia by ultrasound. Chronic smokers, drug addicts, intravenous drug abusers, patients with a history of previous surgeries, with known drug allergies and with complicated hernia were excluded from this cross-sectional study. The Numerical Rating Scale (NRS) was used to see the pain variation and effectiveness of both techniques at 6, 12, 18 and 24 hours. Results: The mean age in the TAP Block Group was 32.0 ± 9.92 years, and the mean age in the Local Wound Infiltration Group was 34.21 ± 10.01 years. There were 108 (98.18%) male and 2(1.81%) female cases with a higher male-to-female ratio. The results indicated that the TAP Block group consistently required fewer rescue analgesic doses than the local wound Infiltration group at all postoperative time points. At 6 hours, 23.63% of patients in the TAP Block group needed additional analgesia, compared to 38.18% in the Wound Infiltration group, though this difference was not statistically significant. However, at 12, 18, and 24 hours, the TAP Block group showed a significantly lower need for rescue analgesia, with p-values of 0.002, and 0.008, respectively. Conclusion: In managing postoperative pain of Inguinal Hernia Repair, TAP Block is superior to Wound Infiltration of local anesthetic agent. After TAP Block NRS remains fewer and a smaller number of rescue doses are needed as compared to Wound infiltration.

Cultural and Economic Aspects of “Pharmacy” Drug Addiction: The Influence of Availability of Medicines and Social Norms in Modern Society

The article is devoted to the study of factors contributing to the development of pharmacy drug addiction, with an emphasis on the availability of drugs and their perception in society. The work examines cultural changes associated with the popularization of prescription drug use, and economic factors, such as pharmaceutical companies' policies and marketing strategies, that influence the increased availability of these drugs. The author analyzes how social norms and popular culture contribute to the normalization of drug abuse, especially among young people. Particular attention is paid to the role of pharmacies, doctors and government regulation in creating conditions for the development of pharmacy drug addiction. The conclusion emphasizes the need for a comprehensive approach to combat this problem, including both tightening control over the distribution of drugs and changing public perceptions of the safe use of pharmaceuticals.

Cariprazine in Hospital Treatment of Acute Psychotic Conditions Due to Comorbid Schizophrenia and Chemical Addictions

Background: endogenous psychoses complicated with different addictions have special psychopathological structure including delirious episodes, true hallucinations combined with typical positive symptoms of schizophrenia. These cases are difficult for treatment due to non-compliance of patients and their bad tolerance to drugs. The aim was to study the most effective psychopharmacological treatment using cariprazine for acute psychotic states in paranoid schizophrenia combined with chemical addictions. Patients and Methods: the study was conducted at psychiatric hospitals of Tomsk region, St. Petersburg, Nizhnevartovsk and Noyabrsk from 2018 to 2024. 208 men aged 18 to 45 years suffering from paranoid schizophrenia and dependent on psychoactive substances were examined. The main group made up 104 in-patients, who took cariprazine alone or in combination with haloperidol or chlorpromazine. The control group included 104 in-patients treated with other antipsychotics (aripiprazole, risperidone, olanzapine). Research methods: clinical and psychopathological, psychometric (PANSS, SANS, CGI, GAF), statistical (Python 3.11.0; R version 3.2.4; SPSS Statistics Base 22.0). Results: It was revealed that when comparing the control group with the main group, similar indicators were observed on the CGI and GAF scales on the 2nd week of the study, and on the 4th week of the study, compared with the control group, an improvement in indicators on the PANSS, SANS, CGI, GAF scales was observed. Conclusions: Cariprazine, compared with other atypical antipsychotics (risperidone, olanzapine, aripiprazole), showed a distinct antipsychotic effect in the treatment of acute psychotic states in patients with schizophrenia dependent on psychoactive substances. By the end of the 2nd week after hospitalization, when treating with cariprazine at an average dose of 3 to 6 mg/day in combination with typical neuroleptics (haloperidol, chlorpromazine) or a tranquilizer, the most pronounced antipsychotic effect is achieved. Subsequent isolated use of cariprazine at a therapeutic dose of 3–4.5 mg/day has an effect similar to that of leading atypical antipsychotics by the end of the 4th week of treatment. Unlike other atypical antipsychotics, cariprazine was more effective in the treatment of negative symptoms of schizophrenia, which made it possible to achieve an improvement in overall functioning, increase the duration of remission, and reduce the risk of rehospitalization and the development of hospitalism.
