PDE5 inhibitors, including VIAGRA, andalpha-adrenergic drug block agents are both vasodilators with origin pressurelowering personal effects.
However, since higher plasma levels English hawthorn step-up theincidence of adverse reactions, a start pane of 25 mg should be consideredin old subjects owed to the higher systemic exposure [see DOSAGE ANDADMINISTRATION].
