calcium channel blockers, beta-adrenoreceptor antagonists.
Effects of DYNAFIL on other medicines:
Sildenafil may potentiate the hypotensive effect of acute and chronic nitrates. Therefore, the concomitant use of DYNAFIL and nitrates or nitric oxide donors is contra-indicated (see “CONTRA-INDICATIONS”).
Concomitant use of DYNAFIL and other antihypertensive medicines may potentiate the antihypertensive
effect of these medicines. A mean additional reduction in supine blood pressure (systolic, 8 mmHg; diastolic, 7 mmHg) was observed in concomitant use of sildenafil and amlodipine.
DYNAFIL did not potentiate the increase in bleeding time caused by aspirin. No significant interactions
were shown between DYNAFIL and tolbutamide (250 mg) or warfarin (40 mg), both being metabolised by
