सारांश

Atazanavir solubility falls as gastric pH rises, so H2 antagonists such as cimetidine can substantially lower its levels. This risks virologic failure and resistance.

इस इंटरैक्शन का सरल भाषा में अर्थ

Atazanavir and Cimetidine 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.

Atazanavir belongs to Anti Virals; Cimetidine belongs to Gastrointestinal Tract.

साक्ष्य स्तर: High

ऐसा क्यों होता है

Increased gastric pH reduces atazanavir dissolution and absorption.

क्या करें
