Vardenafil 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.
Dapoxetine is a selective serotonin reuptake inhibitor, for the treatment of premature ejaculation. In a phase II proof-of-concept study conducted by PPD, dapoxetine demonstrated a statistically significant increase in ejaculatory latency when compared to placebo.
The enhanced effect of Snovitra Super Power is ensured by the presence of two active active ingredients in the composition – Vardenafil 20mg and Dapoxetine 60mg. Their interaction with the circulatory system leads to increased blood circulation efficiency in the pelvic organs. Due to this, the smooth muscles of the penis relaxes, blood rushes to it and a persistent and prolonged erection occurs.
Snovitra Super Power does not lose its effectiveness when used with moderate doses of alcohol or fatty foods. Do not exceed the recommended dose – 1 tablet per day, as this may cause unpleasant side effects.
Vardenafil is used to treat male erectile dysfunction (impotence) and pulmonary arterial hypertension (PAH). Part of the physiological process of erection involves the release of nitric oxide (NO) in the corpus cavernosum. This then activates the enzyme guanylate cyclase which results in increased levels of cyclic guanosine monophosphate (cGMP), leading to smooth muscle relaxation in the corpus cavernosum, resulting in increased inflow of blood and an erection. Vardenafil is a potent and selective inhibitor of cGMP specific phosphodiesterase type 5 (PDE5) which is responsible for degradation of cGMP in the corpus cavernosum.
Dapoxetine is a selective serotonin reuptake inhibitor currently undergoing trials through Alza (under license from GenuPro, a collaboration between Eli Lilly and PPD). Dapoxetine is a short-acting SSRI drug currently being considered for approval by the Food and Drug Administration (FDA) for the treatment of premature ejaculation in men, which would make it the first drug approved for such treatment.
Despite two clinical trials finished in 2006, experts doubt it will be approved by the FDA soon because SSRIs come with undesirable side-effects after long-term use, such as psychiatric problems, dermatological reactions, increase in body weight, lower sex-drive, nausea, headache, upset stomach and weakness, thus not significantly outweighing the benefit of premature ejaculation medication versus the risks.
Vardenafil inhibits the cGMP specific phosphodiesterase type 5 (PDE5) which is responsible for degradation of cGMP in the corpus cavernosum located around the penis. 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. Cyclic GMP causes smooth muscle relaxation and increased blood flow into the corpus cavernosum. The inhibition of phosphodiesterase type 5 (PDE5) by vardenafil enhances erectile function by increasing the amount of cGMP.
Dapoxetine mechanism of action is thought to be related to inhibition of neuronal reuptake of serotonin and subsequent potentiation of serotonin activity. The central ejaculatory neural circuit comprises spinal and cerebral areas that form a highly interconnected network. The sympathetic, parasympathetic, and somatic spinal centers, under the influence of sensory genital and cerebral stimuli integrated and processed at the spinal cord level, act in synergy to command physiologic events occurring during ejaculation. Experimental evidence indicates that serotonin (5-HT), throughout brain descending pathways, exerts an inhibitory role on ejaculation.
Metabolism: Vardenafil is metabolized predominantly by the hepatic enzyme CYP3A4, with contribution from the CYP3A5 and CYP2C isoforms. The major circulating metabolite, M1, results from desethylation at the piperazine moiety of vardenafil. M1 shows a phosphodiesterase selectivity profile similar to that of vardenafil and an in vitro inhibitory potency for PDE5 28% of that of vardenafil.
Absorption: Vardenafil - is rapidly absorbed with absolute bioavailability of approximately 15%./ Dapoxetine - Rapidly absorbed.
Route of elimination: After oral administration, vardenafil is excreted as metabolites predominantly in the feces (approximately 91-95% of administered oral dose) and to a lesser extent in the urine (approximately 2-6% of administered oral dose).
Half life: Vardenafil - 4-5 hours / Dapoxetine - Initial half-life of 1-2 hours.
All medicines may cause side effects, but many people have no, or minor, side effects.Some medical conditions may interact with Vardenafil & Dapoxetine.
Tell your doctor or pharmacist if you have any medical conditions.
Common Vardenafil side effects may include: flushing (warmth, redness, or tingly feeling), stuffy nose, sinus pain, headache, dizziness, upset stomach or back pain.
Common Dapoxetine side effects: feeling of warmth, fever, muscle aches, redness of the face, neck, arms, and occasionally, upper chest, sore throat, stuffy or runny nose.
This is not a complete list of all side effects that may occur. If you have questions about side effects, contact your health care provider.
