Drugs

Drugs are substances with preventive, diagnostic or therapeutic action that act on specific biological processes to restore or modify body functions. Their quality, safety and efficacy are ensured through strict regulatory procedures (Marketing Authorization), production control (GMP) and post‑marketing monitoring (pharmacovigilance). Proper use requires medical prescription and supervision, adherence to dosage and duration, and attention to interactions and contraindications. Self‑medication is limited to OTC and non‑prescription drugs for mild and temporary disorders.
