What is sildenafil tablets used for
For other what is sildenafil tablets used for uses, see. Sildenafil, sold as the brand name. Viagra among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. 3, its effectiveness for treating sexual dysfunction in what is sildenafil tablets used for women has not been demonstrated. 3, common side effects include headaches and heartburn, as well as flushed skin. Caution is advised in those who have cardiovascular disease. Rare but serious side effects include prolonged erections, which can lead to damage to the penis, and sudden-onset hearing loss. Sildenafil should not be taken by people who take nitrates such as nitroglycerin (glycerin trinitrate as this may result in a severe and potentially fatal drop in blood pressure. 3, sildenafil acts by inhibiting cGMP-specific phosphodiesterase type 5 (phosphodiesterase 5, PDE5 an enzyme what is sildenafil tablets used for that promotes degradation of cGMP, which regulates blood flow in the penis. Pfizer scientists, andrew Bell, David Brown, and Nicholas Terrett originally discovered sildenafil as a treatment for various cardiovascular disorders. 4 5, since becoming available in 1998, sildenafil has been a common treatment for erectile dysfunction; its primary competitors are tadalafil (trade name Cialis) and vardenafil (Levitra). Contents Medical uses 50mg tablets of sildenafil Sexual dysfunction The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete intercourse). Its use is now one of the standard treatments for erectile dysfunction, including for men with diabetes mellitus. 6 Antidepressant-associated sexual dysfunction Tentative evidence suggests that sildenafil may help men who experience antidepressant -induced erectile dysfunction. 7 Pulmonary hypertension While sildenafil improves some markers of disease in people with pulmonary arterial hypertension, it does not appear to affect the risk of death or serious side effects as of 2014. 8 Raynaud's phenomenon Sildenafil and other PDE5 inhibitors are used off-label to alleviate vasospasm and treat severe ischemia and ulcers in fingers and toes for people with secondary Raynaud's phenomenon ; 9 10 these drugs have moderate efficacy for reducing the frequency and duration. 9 As of 2016, their role more generally in Raynaud's was not clear. 10 Adverse effects In clinical trials, the most common adverse effects of sildenafil use included headache, flushing, indigestion, nasal congestion, and impaired vision, including photophobia and blurred vision. 2 Some sildenafil users have complained of seeing everything tinted blue ( cyanopsia ). 11 Some complained of blurriness and loss of peripheral vision. In July 2005, the FDA found that sildenafil could lead to vision impairment in rare cases 12 and a number of studies have linked sildenafil use with non-arteritic anterior ischemic optic neuropathy. 13 Rare but serious adverse effects found through postmarketing surveillance include prolonged erections, severe low blood pressure, myocardial infarction (heart attack ventricular arrhythmias, stroke, increased intraocular pressure, and sudden hearing loss. 2 In October 2007, the FDA announced that the labeling for all PDE5 inhibitors, including sildenafil, required a more prominent warning of the potential risk of sudden hearing loss. 14 Interactions Care should be exercised by people who are also taking protease inhibitors for the treatment of HIV infection. Protease what is sildenafil tablets used for inhibitors inhibit the metabolism of sildenafil, effectively multiplying the plasma what is sildenafil tablets used for levels of sildenafil, increasing the incidence and severity of side effects. Those using protease inhibitors are recommended to limit their use of sildenafil to no more than one 25 mg dose every 48 hours. 2 Other drugs that interfere with the metabolism of sildenafil include erythromycin and cimetidine, both of which can also lead to prolonged plasma half-life levels. The use of sildenafil and an 1 blocker (typically prescribed for hypertension or for urologic conditions, such as benign prostatic hypertrophy ) at the same time may lead to low blood pressure, but this effect does not occur if they are taken at least. 15 Contraindications Contraindications include: 2 :11 Concomitant use of nitric oxide donors, organic nitrites and nitrates, 16 such as: Concomitant use of soluble guanylyl cyclase stimulators, such as riociguat Known hypersensitivity to sildenafil Sildenafil should not be used if sexual activity is inadvisable due. Citation needed Nonmedical use Recreational use Sildenafil's popularity with young adults has increased over the years. 17 Sildenafil's trade name, Viagra, is widely recognized in popular culture, and the drug's association with treating erectile dysfunction has led to its recreational use. 18 The reasons behind such use include the belief that the drug increases what is sildenafil tablets used for libido, improves sexual performance, 18 or permanently increases penis size. 19 Studies on the effects of viagra when used recreationally are limited, but suggest it has little effect when used by those not suffering from erectile dysfunction. In one study, a 25-mg dose was shown to cause no significant change in erectile quality, but did reduce the postejaculatory refractory time. 20 This study also noted a significant placebo effect in the control group. 20 Unprescribed recreational use of sildenafil and other PDE5 inhibitors is noted as particularly high among users of illegal drugs. 21 Sildenafil is sometimes used to counteract the effects of other substances, often illicit. 18 Some users mix it with methylenedioxymethamphetamine ( mdma, ecstasy other stimulants, or opiates in an attempt to compensate for the common side effect of erectile dysfunction, a combination known as " sextasy "rockin' and rollin or "trail mix". 18 Mixing with amyl nitrite is particularly dangerous and potentially fatal. 18 Jet lag research The 2007 Ig Nobel Prize in Aviation went to Patricia. Plano, and Diego. Golombek of Universidad Nacional de Quilmes, Argentina, for their discovery that sildenafil helps treat jet lag recovery in hamsters. 22 23 Sports Professional athletes have been documented using sildenafil, believing the opening of their blood vessels will enrich their muscles. In turn, they believe it will enhance their performances. 24 25 Analogs Acetildenafil and other synthetic structural analogs of sildenafil which are PDE5 inhibitors have been found as adulterants in a number of "herbal" aphrodisiac products sold over-the-counter.
Sildenafil tablet use
Sildenafil Viagra - General Information, sildenafil sildenafil tablet use Viagra (in citrate form sold under the names Viagra, Revatio and under various other names, is a drug used to treat male erectile sildenafil tablet use dysfunction (impotence) and pulmonary arterial hypertension (PAH developed by the pharmaceutical company Pfizer. Its primary competitors on the market are tadalafil (Cialis and vardenafil (Levitra). Pharmacology of Sildenafil Viagra, sildenafil Viagra 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. Sildenafil Viagra is a potent and selective inhibitor of cGMP specific phosphodiesterase type 5 (PDE5) which is responsible for degradation of cGMP in the corpus cavernosum. This means that, with Sildenafil Viagra on board, normal sexual stimulation leads to increased levels of cGMP in the corpus cavernosum which leads to better erections. Without sexual stimulation and no activation of the NO/cGMP system, Sildenafil Viagra should not cause an erection. Sildenafil Viagra for patients, patient Information: Sildenafil should be used with caution in patients with anatomical deformation of the penis, sickle cell anemia, multiple myeloma, or leukemia. There is potential cardiac risk of sexual activity in patients with preexisting cardiovascular risk factors. Patients should discontinue further sexual activity and contact the doctor if they experience chest pain, dizziness, or nausea upon initiation of the activity. Sildenafil may cause prolonged erections ( 4 hours) and priapism (painful erections greater than sildenafil tablet use 6 hours in duration). If patients experience prolonged erections or priapism, they should contact their doctors immediately! Effects of Other Drugs on Sildenafil Citrate. In Vitro Studies: Sildenafil metabolism is principally mediated by the cytochrome P450 (CYP) isoforms 3A4 (major route) and 2C9 (minor route). Therefore, inhibitors of these isoenzymes may reduce sildenafil clearance. In Vivo Studies: Cimetidine (800 mg a nonspecific CYP inhibitor, caused a 56 increase in plasma sildenafil concentrations when coadministered with sildenafil citrate (50 mg) to healthy volunteers. When a single 100 mg dose of sildenafil citrate was administered with erythromycin, a specific CYP3A4 inhibitor, at steady state (500 mg bid for 5 days there was a 182 increase in sildenafil systemic exposure (AUC). In addition, coadministration of the HIV protease inhibitor saquinavir, also a CYP3A4 inhibitor, at steady state (1200 mg tid) with sildenafil citrate (100 mg single dose) resulted in a 140 increase in sildenafil Cmax and a 210 increase in sildenafil AUC. Sildenafil citrate had no effect on saquinavir pharmacokinetics. Stronger CYP3A4 inhibitors such as ketoconazole or itraconazole would be expected to have still greater effects, and population data from patients in clinical trials did indicate a reduction in sildenafil clearance when it was coadministered with CYP3A4 inhibitors (such as ketoconazole, erythromycin, or cimetidine). Coadministration with the HIV protease inhibitor ritonavir, which is a highly potent P450 inhibitor, at steady state (400 mg bid) with sildenafil citrate (100 mg single dose) resulted in a 300 (4-fold) increase in sildenafil Cmax and a 1000 (11-fold) increase in sildenafil plasma AUC. At 24 hours the plasma levels of sildenafil were still approximately 200 ng/mL, compared to approximately 5 ng/mL when sildenafil was dosed alone. This is consistent with ritonavir's marked effects sildenafil tablet use on a broad range of P450 substrates. Sildenafil citrate had no effect on ritonavir pharmacokinetics. It can be expected that concomitant administration of CYP3A4 inducers, such as rifampin, will decrease plasma levels of sildenafil. Single doses of antacid (magnesium hydroxide/aluminum hydroxide) did not affect the bioavailability of sildenafil citrate. Pharmacokinetic data from patients in clinical trials showed no effect on sildenafil pharmacokinetics of CYP2C9 inhibitors (such as tolbutamide, warfarin CYP2D6 inhibitors (such as selective serotonin reuptake inhibitors, tricyclic antidepressants thiazide and related diuretics, ACE inhibitors, and calcium channel blockers. The AUC of the active metabolite, N-desmethyl sildenafil, was increased 62 by loop and potassium-sparing diuretics and 102 by nonspecific beta-blockers. These effects on the metabolite are not expected to be of clinical consequence. Effects of Sildenafil Citrate on Other Drugs. In Vitro Studies: Sildenafil is a weak inhibitor of the cytochrome P450 isoforms 1A2, 2C9, 2C19, 2D6, 2E1 and 3A4 (IC50 150 mM). Given sildenafil peak plasma concentrations of approximately 1 mcM after recommended doses, it is unlikely that sildenafil citrate will alter the clearance of substrates of these isoenzymes. In Vivo Studies: When sildenafil citrate 100 mg oral was coadministered with amlodipine, 5 mg or 10 mg oral, to hypertensive patients, the mean additional reduction on supine blood pressure was 8 mmHg systolic and 7 mmHg diastolic. No significant interactions were shown with tolbutamide (250 mg) or warfarin (40 mg both of which are metabolized by CYP2C9. Sildenafil citrate (50 mg) did not potentiate the increase in bleeding time caused by aspirin (150 mg). Sildenafil citrate (50 mg) did not potentiate the hypotensive effect of alcohol in healthy volunteers with mean maximum blood alcohol levels.08. Sildenafil (100 mg) did not affect the steady state pharmacokinetics of the HIV protease inhibitors, saquinavir and ritonavir, both of which are CYP3A4 substrates. Sildenafil Viagra Contraindications, consistent with its known effects on the nitric oxide/cGMP pathway, sildenafil citrate was shown to potentiate the hypotensive effects of nitrates, and its administration to patients who are using organic nitrates either regularly and/or intermittently in any form is therefore contraindicated. After patients have taken sildenafil citrate, it is unknown when nitrates, if necessary, can be safely administered. Based on the pharmacokinetic profile of a single 100 mg oral dose given to healthy normal volunteers, the plasma levels of sildenafil at 24 hours post dose are approximately 2 ng/mL (compared to peak plasma levels of approximately 440 ng/mL). In the following patients: age 65, hepatic impairment (.g., cirrhosis severe renal impairment (.g., creatine clearance 30 mL/min and concomitant use of potent cytochrome P450 3A4 inhibitors (erythromycin plasma levels of sildenafil at 24 hours post dose have been found to. Although sildenafil tablet use plasma levels of sildenafil at 24 hours post dose are much lower than at peak concentration, it is unknown whether nitrates can be safely coadministered at this time point. Sildenafil citrate is contraindicated in patients with a known hypersensitivity to any component of the tablet. Additional information about Sildenafil Viagra, sildenafil Viagra Indication: For the treatment of erectile dysfunction. Mechanism Of Action: Sildenafil Viagra 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 Sildenafil Viagra enhances erectile function by increasing the amount of cGMP.
