Proportion Of Non-steroidal Anti-inflammatory Drugs Research Articles

The analysis of prolonged-release drugs at the Ukrainian pharmaceutical market

Aim. To analyze the range of prolonged-release dosage forms at the Ukrainian pharmaceutical market focusing on the pharmacotherapeutic groups that are insufficiently saturated with prolonged-release drugs, in particular to determine the proportion of non-steroidal anti-inflammatory drugs (NSAIDs). Materials and methods. The research was conducted in accordance with the data of the State Registry of Medicines of Ukraine and the АТС classification system. The methods of scientific analysis, in particular methods of grouping and comparison, marketing methods of analysis were applied. Results. The study of the assortment of prolonged-release drugs registered at the Ukrainian pharmaceutical market has been performed. The structure of the assortment by manufacturer, dosage forms, the АТС classification system has been analyzed. As a result of the study, it has been found that 202 trade names of prolonged-release drugs are registered in Ukraine. Most of them (196 names, 84 %) are medicines of foreign manufacturers. Prolonged-release drugs registered in Ukraine are mostly presented in the form of tablets and capsules, but tablets (72.77 %) are the largest part. The analysis of distribution of prolonged-release drugs by the ATC classification groups has shown that a significant number of prolonged-release drugs belongs to group N – Nervous system (80 trade names), and group C – Cardiovascular system (44 trade names). The share of group M – Musculoskeletal system, in particular prolonged-release NSAIDs, is insignificant (9 trade names). Conclusions. The marketing research of the prolonged-release drugs conducted allowed us to characterize the structure of the assortment of the Ukrainian market by pharmacotherapeutic groups, manufacturers and dosage forms. As a result of the research, the current assortment of prolonged-release NSAIDs has been determined.

Dyspepsia, Ulcer Disease – Helicobacter pylori, Gastroesophageal Reflux Disease

Prevalence of H. pylori (HP) is declining, whereas reflux disease and the proportion of non-steroidal antiinflammatory drugs (NSAR) to HP-induced ulcers increase. Eradication heals HP-ulcer disease, interrupts cancerous progression and can improve dyspeptic symptoms. NSAR-ulcers heal under proton pump inhibitor (PPI) therapy but tend to recur after reexposition. Anticoagulants and antiplatlet agents increase the risk additionally. PPI reduces NSAR-ulcer recurrence. Reflux patients with severe inflammation and complications often need long-term therapy. Barrett’s esophagus patients are at risk of esophageal adenocarcinoma.

Non-Steroidal Anti-Inflammatory Drug Use and Essential Tremor

Background: Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to be inversely related to Parkinson's disease and Alzheimer's disease, both of which may share common mechanisms with essential tremor (ET). Use of these medications has not been studied in ET cases vs. controls. Objective: To investigate the relationships between NSAID (esp. ibuprofen) and aspirin use and ET. Methods: Subjects were enrolled in a case-control study of the environmental epidemiology of ET at the Columbia University Medical Center (CUMC; 2009-2014). We compared 92 ET cases to 107 controls (∼1:1 matching) in terms of self-reported NSAID (esp. ibuprofen) and aspirin use. Results: The proportion of NSAID or aspirin users (current or past) was similar in ET cases and controls (for current user, p = 0.66; for past user, p = 0.90). Among users, however, the total dosage of ibuprofen (frequency in past year × number of tablets taken at a time × typical average strength of tablets) was higher in controls than ET cases (p = 0.04). ET cases and controls did not differ with respect to aspirin use in the past year. Conclusion: The proportion of NSAID or aspirin users did not differ in ET cases or controls; yet interestingly, ibuprofen use was less in ET cases than in controls. The latter raises the possibility that ibuprofen use could have a potential protective role in ET.

A study of the changes in the cause of peptic ulcer bleeding

To clarify the frequency of and changes in the cause of peptic ulcer bleeding. This study retrospectively evaluated the out- and inpatients who underwent endoscopy between 2002 to 2008. The subjects were patients presenting with peptic ulcer bleeding. The details of these patients were obtained from their endoscopic reports and medical records. The rates of Helicobacter pylori (H. pylori) infection were significantly low (P = 0.039), while the proportion of nonsteroidal antiinflammatory drugs (NSAIDs) users and vascular disease significantly increased over the period studied (P = 0.034 and P = 0.04, respectively). However, there was no significant difference in the proportion of low-dose aspirin users (P = 0.832). It's found that the primary cause of peptic ulcer bleeding changed from H. pylori infection to use of NSAIDs over the 7-year period of study. It seems that the number of low-dose aspirin users has increased with the increase in the proportion of vascular disease. It is necessary to take measures to prevent peptic ulcer bleeding among NSAIDs and low dose aspirin users.
