Therapeutic Approaches for Treatment and Management of Depressive Disorder: A Comprehensive Review

Abstract

Depression, which is associated with high levels of cognitive and functional activity, melancholy, reduced activity, difficulty understanding, failure to focus, dietary abnormalities, sleep disturbances, and emotions of feelings of sadness, suicidal thoughts, and lack of hope are symptoms of a psychoneurotic disorder. It is a common and recurring disorder with a high morbidity and death rate throughout the world. Despite advances in depression treatment, such as selective serotonin reuptake inhibitors (SSRIs) and selective norepinephrine reuptake inhibitors (SNRIs), there remain several unmet clinical requirements in terms of effectiveness and adverse effects. These requirements range from enhanced to decreased side effects like emesis and erectile problems in treatment-resistant patients. There are a variety of combination therapies available to meet these needs. Several combination medicines and novel strategies have been found, all of which have the potential to improve one or so more areas. The kinds of targets and methods being used are extremely diverse. Therapeutic approaches, on the one hand, provide the benefits of SSRIs while including alternative routes in an attempt to improve efficacy or reduce undesirable effects. Neurotrophins (BDNF, IGF) are more novel targets on the other end of the spectrum, based on the most recent research suggesting antidepressants enhance neurogenesis. Antidepressants act by blocking many proteins, such as neurotransmitter transporters and G-protein coupled receptor families, in the brain. Some of the computational approaches that are useful for uncovering drug action mechanisms and are important for drug development are molecular docking, molecular dynamics, and drug candidates.
