Yes, proton pump inhibitors (PPIs) can interact with aspirin, leading to potential side effects. PPIs are a type of medication commonly used to treat gastroesophageal reflux disease, peptic ulcers, and other gastric acid-related conditions [1]. Aspirin, on the other hand, is a nonsteroidal anti-inflammatory drug (NSAID) often used for its antiplatelet and analgesic properties [2].
The interaction between PPIs and aspirin occurs due to the effect of PPIs on gastric pH. PPIs work by reducing gastric acid production, thereby increasing the gastric pH [1]. Aspirin requires an acidic environment for optimal absorption and conversion to its active form [3]. Consequently, the use of PPIs can reduce aspirin's bioavailability, leading to decreased effectiveness of aspirin's therapeutic effects [3].
Additionally, the interaction between PPIs and aspirin may also increase the risk of gastrointestinal (GI) side effects, such as ulcers and bleeding, due to the local irritant effects of aspirin [4]. This risk is particularly relevant for individuals taking high-dose aspirin or using aspirin for long-term therapy [4].
It is essential to consult a healthcare professional for personalized advice on managing the interaction between PPIs and aspirin. Strategies to minimize the interaction may include separating the administration times of these medications, using alternative antiplatelet agents, or adjusting the dosage of aspirin [3][4].
