[Proton pump inhibitors when using clopidogrel: balance between necessity and disadvantages]

Area of Science:

• Cardiology
• Gastroenterology
• Pharmacology

Background:

• Proton pump inhibitors (PPIs) are recommended for patients using aspirin (acetylsalicylic acid, ASA) or carbasalate calcium to prevent gastrointestinal (GI) bleeding.
• Clopidogrel monotherapy is increasingly prescribed, raising questions about similar GI bleeding risks.

Purpose of the Study:

• To compare the risk of GI bleeding in patients using clopidogrel monotherapy versus aspirin (ASA).
• To determine if PPIs should be recommended for clopidogrel users with additional GI bleeding risk factors.

Main Methods:

• A systematic literature review was conducted.
• Included 9 studies comparing GI bleeding risk between clopidogrel monotherapy and ASA.

Main Results:

• The risk of GI bleeding is elevated with clopidogrel monotherapy.
• The GI bleeding risk associated with clopidogrel monotherapy is comparable to that of aspirin (ASA).

Conclusions:

• Prescribing pantoprazole is recommended for patients on clopidogrel monotherapy with additional GI bleeding risk factors.
• This recommendation aligns with the current practice for low-dose ASA.
• The benefits of PPI use must be weighed against potential disadvantages.
