Tadalafil inhibits phosphodiesterase.  This relaxes the blood vessels around the penis allowing blood to build up in the vessels of the penis.  This method helps a man to maintain an erection but only produces this result if the man is sexually stimulated.

Clinical studies showed that the drug is effective from around 30 minutes after taking Apcalis.  The effects of the drug remain active for upto 36 hours.  This means that following sexual intercourse and recovery a man can expect to achieve further erections over the next 24-36 hours if sexually stimulated.

For information regarding side-effects and medical precautions, please refer to the Apcalis FAQs and Apcalis Information sections.

You can buy Apcalis from Exact-Pharma.
