Pharmacy Technician Study Guide: Drug Classifications

Drug Classifications A.C.E. Inhibitors - Angiotensin Converting Enzyme Inhibitors block the conversion of angiotensin I to angiotensin II. Avoiding Angiotensin II may avoid increased blood pressure and vasoconstriction. They usually have the suffix "PRIL" A.2.R.B. - Angiotensin 2 Receptor Blockers block Angiotensin 2 enzymes from specific receptor sites. Avoiding Angiotensin 2 activity helps prohibit vasoconstriction. They usually have the suffix "ARTAN" Anti-Biotics - Anti-Biotics inhibit the reproduction of new Bacteria cells. There are several varieties and Drug Class Definitions of Anti-Biotics.Anti-Convulsants - Anti-Convulsants suppress the rapid firing of neurons in the nervous system (brain). Also known as Anti-epileptic drugs and Anti-Seizure drugs.Anti-Diabetics / Sulfonylureas - lower glucose levels in the blood. They are only used to treat Type II Diabetes.Benzodiazepines - Also know as "Benzos". Benzos are used as anti-anxiety agents, muscle relaxants, sedatives, and hypnotics. They usually have the suffix "PAM".Beta Blockers (B1) - Also known as Beta-adrenergic blocking agents. Block adrenaline receptors, which are part of the central nervous system and mediate a "Fight or flight" response, which would cause actions in the heart. They usually have the suffix "OLOL".Calcium Channel Blockers - Calcium channel blockers work by blocking calcium channels in cardiac muscle and blood vessels, thereby slowing down activity in the heart.Diuretics - Diuretics are primarily used to treat hypertension. They promote evacuation of water from the body, which decreases the load on the cardiovascular system.HMG-CoA Reductase Inhibitors - Also known as Statins, They inhibit the body's cholesterol production and usually have the suffix "STATIN".NSAID - Non Steroidal Anti-Inflammatory Drugs are commonly used as pain killers and Fever Reducers. They are non-narcotic and can be sold OTC.Opioid - Opioids provide an analgesic effect by decreasing the perception of pain and
