what is pharmaceutical

Pharmaceuticals are drugs used for medicinal purposes, such as to prevent, diagnose, treat, or cure diseases. They are special preparations used in modern and traditional medicine and are essential for the prevention and treatment of diseases. Pharmaceutical companies discover, develop, produce, and market pharmaceutical drugs for use as medications to be administered to patients, with the aim to cure and prevent diseases or alleviate symptoms. Pharmaceutical drugs can be classified by chemical group, by the way they work in the body, and by therapeutic use. They can be generic or brand medications and medical devices. Pharmaceuticals are subject to a variety of laws and regulations that govern the patenting, testing, safety, efficacy using drug testing, and marketing of drugs. There are different schedules of pharmaceutical drugs, which determine their availability and the level of control over their distribution. Ensuring regular access to good quality, safe, and affordable medicines is still a challenge for many countries.
