التداخل بين أورفينادرين وأسبرين وكافيين وتادالافيل

When administered in combination with aspirin, tadalafil 20 mg did not prolong bleeding time, relative to aspirin alone.

Potential for CIALIS to Affect Other Drugs Aspirin — Tadalafil did not potentiate the increase in bleeding time caused by aspirin.

When tadalafil was administered to subjects taking theophylline, a small augmentation (3 beats per minute) of the increase in heart rate associated with theophylline was observed.

CYP1A2 (e.g. Theophylline) — Tadalafil had no significant effect on the pharmacokinetics of theophylline.
