What Are Proton Pump Inhibitors
Proton pump inhibitors (PPIs) are a class of medications that reduce stomach acid production. They are among the most commonly prescribed and purchased medications in pharmacy practice, making them a high-yield topic for the PTCE.
Common PPIs
The generic names in this class share the "-prazole" suffix, making them easy to identify:
- Omeprazole (Prilosec) - available both by prescription and over the counter
- Esomeprazole (Nexium) - also available OTC
- Pantoprazole (Protonix) - commonly used in hospital settings, available as IV formulation
- Lansoprazole (Prevacid)
Common Uses
PPIs are used for conditions related to excess stomach acid, including gastroesophageal reflux disease (GERD) and peptic ulcer disease. They are also used in combination with antibiotics for certain stomach infections.
Key Counseling Points
PPIs are typically taken before a meal, often in the morning before breakfast. This timing matters because the medication works best when the stomach is actively producing acid during digestion. Some PPI capsules should not be opened or crushed, though others are designed to be opened and sprinkled on food.
Exam Relevance
For the PTCE, focus on recognizing the "-prazole" suffix, knowing common brand/generic pairs, understanding that some PPIs are available OTC, and knowing the general timing recommendation of taking them before meals. PPIs are likely to appear in questions about drug classification, OTC availability, or patient counseling scenarios.
