Interação entre Sildenafila e Silodosina

Caution is advised when SILDENAFIL ORAL FILM is co-administered with alpha-blockers or antihypertensives.

Hypotension when Co-administered with Alpha-blockers or Antihypertensives Alpha-blockers Caution is advised when PDE5 inhibitors are co-administered with alpha-blockers.

Consider the following: Patients should be stable on alpha-blocker therapy prior to initiating a PDE5 inhibitor.

Patients who demonstrate hemodynamic instability on alpha-blocker therapy alone are at increased risk of symptomatic hypotension with concomitant use of PDE5 inhibitors.

In patients who are stable on alpha-blocker therapy, PDE5 inhibitors should be initiated at the lowest dose [see Dosage and Administration ( 2.2 ) ] .

Caution is also advised when alpha-adrenergic blocking agents including silodosin capsules are co‑administered with PDE5 inhibitors.

Concomitant use of PDE5 inhibitors with alpha-blockers including silodosin capsules can potentially cause symptomatic hypotension.

PDE5 Inhibitors Co‑administration of silodosin capsules with a single dose of 100 mg sildenafil or 20 mg tadalafil was evaluated in a placebo-controlled clinical study that included 24 healthy male subjects, 45 to 78 years of age.

Alpha-adrenergic blockers and PDE5 inhibitors are both vasodilators that can lower blood pressure.

During this period, the total number of positive orthostatic test results was greater in the group receiving silodosin capsules plus a PDE5 inhibitor compared with silodosin capsules alone.
