Psoriasis is a chronic, inflammatory skin condition marked by red, scaly plaques, typically on the scalp, elbows, and knees, though it can affect other areas like the hands, feet, and trunk. It involves a combination of genetic predisposition and environmental triggers such as trauma, stress, or medications, and can lead to systemic issues in various organs. The disease is characterized by epidermal hyperproliferation, inflammatory infiltration, and abnormal angiogenesis. Symptoms commonly include itching, irritation, and pain, and psoriasis significantly impacts quality of life. Various forms of psoriasis exist, including plaque, guttate, pustular, and erythrodermic types.

Treatment varies based on disease severity, with mild psoriasis managed by topical treatments like corticosteroids, emollients, and vitamin D3 analogues. More severe cases require systemic therapies or phototherapy. Evaluating prescribing patterns is essential for ensuring rational drug use, as inappropriate prescribing can lead to ineffective treatment, increased costs, and adverse effects. Adherence to prescribed medication is crucial for successful treatment, and patient preferences, treatment efficacy, and comorbidities influence medication choices. Monitoring and optimizing drug use can help minimize side effects and improve treatment outcomes.
