Interação entre Nifedipino e Silodosina

Central Alpha1-Blockers Doxazosin: Healthy volunteers participating in a multiple dose doxazosin-nifedipine interaction study received 2 mg doxazosin q.d. alone or combined with 20 mg nifedipine ER b.i.d. Co-administration of nifedipine resulted in a decrease in AUC and C max of doxazosin to 83% and 86% of the values in the absence of nifedipine, respectively.

However, patients in the Phase 3 clinical studies taking concomitant antihypertensive medications with silodosin capsules did not experience a significant increase in the incidence of syncope, dizziness, or orthostasis.

Nevertheless, exercise caution during concomitant use with antihypertensives and monitor patients for possible adverse events [see ADVERSE REACTIONS (6.1)

Exercise caution during concomitant use with antihypertensives and monitor patients for possible adverse events [see WARNINGS AND PRECAUTIONS (5.5) ].

A specific pharmacodynamic interaction study between silodosin and antihypertensive agents has not been performed.

Other Concomitant Drug Therapy Antihypertensives The pharmacodynamic interactions between silodosin and antihypertensives have not been rigorously investigated in a clinical study.
