    Tadalafil mechanism of action


    Penile erection during sexual stimulation is caused by increased penile blood flow resulting from the relaxation of penile arteries and the smooth muscle of the corpus cavernosum. This response is mediated by the release of nitric oxide (NO) from nerve terminals and endothelial cells, which stimulates the synthesis of c GMP in smooth muscle cells. Cyclic GMP relaxes smooth muscle and increases blood flow to the corpus cavernosum. The inhibition of phosphodiesterase type 5 (PDE5) enhances erectile function by increasing the amount of c GMP. However, because sexual stimulation is required to initiate the local penile release of nitric oxide, tadalafil's inhibition of PDE5 will have no effect without direct sexual stimulation of the penis. The recommended tadalafil starting dose for most men is 10 mg, taken as needed before sexual activity (but not more than once daily). The dose may be increased to 20 mg or decreased to 5 mg, per its efficacy and the man's personal tolerance of the drug. To avoid the inconvenience of a man having to program and plan using tadalafil around the time of his anticipated sexual activity, Lilly ICOS began a clinical development program to evaluate the risks and benefits of chronic, once-daily use of the drug. ciprofloxacino para que se usa In order to use Medscape, your browser must be set to accept cookies delivered by the Medscape site.
