Sintesi

Acalabrutinib capsules dissolve poorly at higher gastric pH, so omeprazole can reduce its absorption and exposure. This may lower efficacy in patients with B-cell malignancies.

Cosa significa questa interazione in parole semplici

Acalabrutinib and Omeprazole can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Acalabrutinib belongs to Oncology; Omeprazole belongs to Gastrointestinal Tract.

Livello di evidenza: High

Perché avviene

PPI-induced rise in gastric pH reduces acalabrutinib solubility and absorption.

Cosa fare

Avoid the PPI where possible, and consider an antacid or H2 blocker with appropriate timing instead. The tablet formulation is not affected by gastric pH.

Cosa chiedere al farmacista
