Apcalis is an effective, reversible, selective inhibitor of phosphodiesterase type 5 (PDE 5) specific to cyclic guanosine monophosphate (cGMP). When sexual stimulation causes local release of nitric oxide, inhibition of PDE 5 by Cialis leads to increase of cGMP levels in the cavernous body of penis.

Apcalis improves erection and let’s achieve a successful sexual intercourse. The drug acts for 36 hours. If sexual arousal is present the effect appears even after 16 minutes after the medication was taken. It is preferable not to use Apcalis with grapefruit juice, alcoholic beverages, tobacco.
