The Introductction of Tadalafil
Tadalafil, a selective and reversible inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase 5 (PDE5). When sexual stimulation results in the local release of nitric oxide, PDE5 is inhibited by tadalafil, increasing cGMP levels in the corpus cavernosum, which causes smooth muscle relaxation and blood flow into penile tissue, resulting in an erection, as in asexual stimulation.
Erectile dysfunction and pulmonary hypertension.
The recommended dose of this product is 10mg, which is taken before sexual activity and is not affected by food. If the effect of taking 10mg is not significant, you can take 20mg, at least 30 minutes before sex.
Clinical studies have shown that tadalafil can enhance the antihypertensive effect of nitrates. This is thought to be the result of the combined action of nitrates and tadalafil on the nitric oxide/cGMP pathway. Therefore, it is contraindicated in patients taking any form of nitrates.
