Diabetes Medications Overview for Pharmacy Techs

Common diabetes drug classes and key facts for the PTCE.

January 25, 2026

Why Diabetes Drugs Are High-Yield

Diabetes is extremely common, and its medications are among the most frequently dispensed. The PTCE expects you to recognize major classes, general mechanisms, and storage considerations.

Insulin

Used by type 1 and many type 2 diabetes patients. Categories include rapid-acting, short-acting, intermediate-acting, and long-acting. Insulin requires proper storage - typically refrigerated until opened, then room temperature for a limited period.

Metformin

Metformin (Glucophage) is usually the first oral medication for type 2 diabetes and one of the most commonly dispensed medications overall. Available in immediate-release and extended-release. Generally taken with food.

Sulfonylureas

Glipizide (Glucotrol) and glimepiride (Amaryl) stimulate insulin release. A key risk is low blood sugar, an important counseling point.

SGLT2 Inhibitors

Generic names end in "-gliflozin." Empagliflozin (Jardiance) and dapagliflozin (Farxiga) are common. They help kidneys remove excess sugar through urine.

GLP-1 Receptor Agonists

Semaglutide (Ozempic) and liraglutide (Victoza) are injectable GLP-1 receptor agonists, increasingly common in pharmacy practice.

Study Tips

Focus on recognizing drug names by class using suffix patterns. Build a reference chart with class, common examples, route, and one storage or handling note. This organized approach is more efficient than memorizing drugs in isolation.
