सारांश

Cimetidine reduces theophylline clearance and can substantially raise serum levels, risking nausea, tachycardia, arrhythmia and seizures. Theophylline has a narrow therapeutic index so this is clinically important.

इस इंटरैक्शन का सरल भाषा में अर्थ

Cimetidine and Theophylline 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.

Cimetidine belongs to Gastrointestinal Tract; Theophylline belongs to Respiratory.

साक्ष्य स्तर: High

ऐसा क्यों होता है

Cimetidine inhibits CYP1A2 (and CYP3A4), decreasing theophylline metabolism.
