The term pharmacy is derived from the Greek word pharmakon, which means “medicine” or “drug.” Pharmacy can be defined as the art and science of preparing and dispensing medications and providing drug and related information to the public. The concept of pharmacy involves interpreting prescription, compounding, labeling and dispensing drugs and drug-related devices, counseling and monitoring the patients by giving important information related to the usage of the medicament.

Pharmacy in the field of the health profession links chemical sciences with the health sciences, and it ensures safe and effective use of the pharmaceutical drugs.

The present approach of professional practice in a rational way is referred as “pharmaceutical care.” According to this concept, an important role of the pharmacists is “the responsible provision of drug therapy for the purpose of achieving definite outcomes that improve patient’s quality of life.”
