How it works
From the US prescribing label for the same active substance (Tadalafil). It describes the substance, not this exact product.
Penile erection during sexual stimulation is caused by increased penile blood flow resulting from the relaxation of penile arteries and corpus cavernosal smooth muscle.
This response is mediated by the release of nitric oxide (NO) from nerve terminals and endothelial cells, which stimulates the synthesis of cGMP in smooth muscle cells.
Metabolism — Tadalafil is predominantly metabolized by CYP3A4 to a catechol metabolite.
Tadalafil is excreted predominantly as metabolites, mainly in the feces (approximately 61% of the dose) and to a lesser extent in the urine (approximately 36% of the dose).
The rate and extent of absorption of tadalafil are not influenced by food; thus tadalafil tablets may be taken with or without food.
