The recommended starting dosage for treating erectile dysfunction is Levitra 10 mg one hour prior to sexual activity. azithromycin brand name One of the most asked questions about Levitra is that "how long does it take for Levitra to take effect? " the answer is that the effects of Levitra will be noticed within a quarter an hour after administration. On average the effects of Levitra can last between 4 and 5 hours. However, it can also take 1 to 2 days in some men; this can only take place at minimal sexual arousal. Levitra can also cause serious side effects just like viagra, but it all relies on the quantity of Levitra taken. It is very important that you use Levitra in small portions possible.

Patients should stop STENDRA and seek medical care if a sudden loss of vision occurs in one or both eyes, which could be a sign of Non Arteritic Ischemic Optic Neuropathy (NAION).

STENDRA is a phosphodiesterase 5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction. In patients on stable alpha-blocker therapy, the recommended starting dose of STENDRA is 50 mg. DOSAGE AND ADMINISTRATION For most patients, the starting dose is 100 mg taken approximately 30 minutes before sexual activity, on an as needed basis. The dose may be increased to 200 mg or decreased to 50 mg based on efficacy and/or tolerability. DOSAGE FORMS AND STRENGTHS Tablets: 50 mg, 100 mg, 200 mg Phosphodiesterase-5 Enzyme Inhibitor. Mechanism of Action The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation. NO then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (c GMP), producing smooth muscle relaxation in the corpus cavernosum and allowing inflow of blood. Sildenafil has no direct relaxant effect on isolated human corpus cavernosum, but enhances the effect of nitric oxide (NO) by inhibiting phosphodiesterase type 5 (PDE5), which is responsible for degradation of c GMP in the corpus cavernosum. Vardenafil was co-marketed by Bayer Pharmaceuticals, Glaxo Smith Kline, and Schering-Plough under the trade name Levitra. As of 2005, the co-promotion rights of GSK on Levitra have been returned to Bayer in many markets outside the U. In Italy, Bayer sells vardenafil as Levitra and GSK sells it as Vivanza. Thus, because of European Union trade rules, parallel imports might result in Vivanza sold next to Levitra in the EU. An orally disintegrating form, marketed as Staxyn and Levitra Soft, has been gaining approvals in countries such as the United States inhibitors; it is closely related in function to sildenafil citrate (Viagra) and tadalafil (Cialis). The difference between the vardenafil molecule and sildenafil citrate is a nitrogen atom's position and the change of sildenafil's piperazine ring methyl group to an ethyl group. Tadalafil is structurally different from both sildenafil and vardenafil. Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's.
