Visual disorders associated with omeprazole and their relation to CYP2C19 polymorphism

Pharmacogenetics. 2002 Jan;12(1):73-5. doi: 10.1097/00008571-200201000-00010.

Abstract

Risk factors for patients developing visual disturbances in association with proton pump inhibitors are unknown. As omeprazole is substantially metabolized by polymorphic CYP2C19, we retrospectively identified and genotyped patients who experienced this adverse reaction. Among 29 patients, we found two poor metabolizers (PMs) of CYP2C19. The PM genotype does not appear to be a risk factor for omeprazole-associated visual disorders.
