Pharmacy (from the Greek φάρμακον = drug) is the profession charged with ensuring the safe use of medication. Traditionally, pharmacists have compounded and dispensed medications on the orders of physicians. More recently, pharmacy has come to include other services related to patient care including clinical practice, medication review, and drug information. Some of these new pharmaceutical roles are now mandated by law in various legislatures. Pharmacists, therefore, are drug therapy experts, and the primary health professionals who optimize medication management to produce positive health-outcomes.
