erectile dysfunction

Vardenafil (Vivanza) is an oral therapy for the treatment of erectile dysfunction. It is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles. During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum. Nitric oxide activates the enzyme guanylate cyclase resulting in increased synthesis of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum. The cGMP in turn triggers smooth muscle relaxation, allowing increased blood flow into the penis, resulting in erection. The tissue concentration of cGMP is regulated by both the rates of synthesis and degradation via phosphodiesterases (PDEs). The most abundant PDE in the human corpus cavernosum is the cGMPspecific phosphodiesterase type 5 (PDE5); therefore, the inhibition of PDE5 enhances erectile function by increasing the amount of cGMP.

Phentolamine mesylate (Phentolamine methanesulfonate) is a nonselective alpha-adrenergic antagonist used to treat hypertension and hypertensive emergencies, pheochromocytoma, vasospasm of [RAYNAUD DISEASE] and frostbite, clonidine withdrawal syndrome, impotence, and peripheral vascular disease.

Yohimbine hydrochloride (Antagonil) is a plant alkaloid with alpha-2-adrenergic blocking activity. Yohimbine has been used as a mydriatic and in the treatment of ERECTILE DYSFUNCTION.

Nortadalafil (Demethyl Tadalafil) is demethyl Tadalafil, which is a PDE5 inhibitor, treating erectile dysfunction (ED) ; and under the name Adcirca for the treatment of pulmonary arterial hypertensio.

Prostaglandin E1 (Alprostadil) is the naturally occurring prostaglandin E1 (PGE1) which displays a variety of pharmacologic actions. Prostaglandin E1 is a potent vasodilator agent that increases peripheral blood flow, inhibits platelet aggregation, and induces bronchodilation. Used in the treatment of erectile dysfunction, this agent produces corporal smooth muscle relaxation by binding to PGE receptors, resulting in the activation of adenylate cyclase and the subsequent accumulation of 3'5'-cAMP.

Moxisylyte is also used for the short-term treatment of primary Reynaud's syndrome, a condition where the fingers and toes become discoloured in response to cold or emotional distress. Moxisylyte helps by improving blood circulation to the extremities. It is also used locally in the eye to reverse the mydriasis caused by phenylephrine and other sympathomimetic agents.
