Pharmacy is a branch of health care that focuses on the preparation, dispensing, and proper utilization of medications. It involves the science and practice of formulating drugs, ensuring their safe and effective use, and providing patient care through medication management. Here’s a detailed overview of pharmacy:

Components of Pharmacy

Pharmaceutical Sciences:

Pharmacology: The study of how drugs interact with biological systems. It includes understanding drug mechanisms, effects, and potential side effects. Pharmaceutics: The science of formulating and preparing medications. It involves the development of dosage forms like tablets, injections, and creams. Pharmacokinetics: The study of how drugs are absorbed, distributed, metabolized, and excreted by the body. Pharmacodynamics: The study of the physiological effects of drugs and their mechanisms of action.
