Viagra

Viagra is one of the best-known treatments for erectile dysfunction (ED). ED is caused by insufficient blood flow to the penis, resulting in the inability to maintain an erection. Viagra can dramatically enhance the quality of an erection by increasing blood flow to the penis. Its effect lasts for 4-6 hours. Viagra is widely known to treat PAH (pulmonary arterial hypertension).

Also known as:  Sildenafil Citrate.

Description

Viagra is an anti-impotence drug which enables men to achieve and sustain an erection.

The active ingredient of Viagra is Sildenafil Citrate (PDE-5 inhibitor). In response to sexual arousal, Sildenafil Citrate stimulates the release of nitric oxide (NO) in the corpus cavernosum. Nitric oxide activates the lyase enzyme which is followed by increasing levels of cyclic guanosine monophosphate (cGMP). This cyclic nucleotide relaxes smooth muscles in blood vessels of the corpus cavernosum, increasing blood flow and thus inducing an erection.

Along with the treatment of erectile disorders, Viagra effectively prolongs sexual performance, preventing premature ejaculation (PE).

Sildenafil Citrate is also used in the treatment of PAH (pulmonary arterial hypertension).

Viagra is also known as Aphrodil, Caverta, Kamagra, Suhagra, Edegra, Erasmo, Penegra, Revatio, Supra, Silagra, Zwagra.

Viagra does not protect you or your partner from sexually transmitted diseases (including HIV) or from pregnancy.

Dosage

Take one Viagra pill orally with a full glass of water, 30-60 minutes before sex.

The dosage depends on the overall health of the patient. Do not take more than one pill per day.

Take Viagra on an empty stomach, as fatty meals, grapefruit juice and alcohol can interfere with the effectiveness of the medication.

Overdose

If you take an overdose of Viagra, you should seek emergency medical attention or contact your healthcare provider immediately.

Storage

Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F) and away from excess moisture and heat. Throw away any unused medicine after the expiration date. Keep out of the reach of children.

Side effect occurrence does not only depend on medication you are taking, but also on your overall health and other factors.

Contraindications

Do not take Viagra if you are allergic to any of Viagra’s components.

Do not take Viagra if you are also using organic nitrates, nitrate drugs for chest pain or heart condition (e.g., nitroglycerin, isosorbide dinitrate and isosorbide mononitrate), nitrates as amyl nitrate or nitrite ("poppers").

Do not take Viagra if you take other medications to treat erectile dysfunction or pulmonary arterial hypertension, such as riociguat (Adempas).

Do not take Viagra if you are taking erythromycin, alpha-blockers, ketoconazole, itraconazole (Sporanox or Nizoral), ritonavir (Norvir) or indinavir (Crixivan).

Do not consume alcohol while using Viagra, as it can lower your blood pressure, causing dizziness and rapid heart rate (tachycardia).

Do not drive or operate machinery while taking the medication.

Contact you doctor or health care professional right away if your erection lasts longer than 4 hours or if it becomes painful.

Viagra does not protect you or your partner from sexually transmitted diseases or pregnancy.

Viagra can be dangerous for children and women.

Compared with placebo, sildenafil produced higher levels of successful sexual stimulation, intercourse success, satisfaction with sexual life and sexual relationship, erectile function, overall sexual satisfaction, and an improved Erectile Dysfunction Inventory of Treatment Satisfaction score, with no clinically relevant effects on vital signs. Sildenafil seemed more effective in patients with incomplete SCI than in those with complete SCI, producing significant improvements, compared with placebo, in a number of measures only in patients with incomplete SCI. All patients who expressed a preference selected sildenafil over placebo, although the drug had no effect on patient QoL. Sildenafil was well tolerated, with a profile comparable to that of placebo.

In this single centre, randomized double-blind, placebo-controlled trial, we included 52 patients with pulmonary hypertension [mean pulmonary artery pressure (PAP) >25 mmHg; pulmonary artery wedge pressure (PAWP) >15 mmHg] due to HFpEF [left ventricular ejection fraction (LVEF) ≥45%]. Patients were randomized to the PDE-5 inhibitor sildenafil, titrated to 60 mg three times a day, or placebo for 12 weeks. The primary endpoint was change in mean PAP after 12 weeks. Secondary endpoints were change in mean PAWP, cardiac output, and peak oxygen consumption (peak VO2). Mean age was 74 ± 10 years, 71% was female, LVEF was 58%, median NT-proBNP level was 1087 (535-1945) ng/L. After 12 weeks, change in mean PAP was -2.4 (95% CI -4.5 to -0.3) mmHg in patients who received sildenafil, vs. -4.7 (95% CI -7.1 to -2.3) mmHg in placebo patients (P = 0.14). Sildenafil did not have a favourable effect on PAWP, cardiac output, and peak VO2. Adverse events were overall comparable between groups.

Experiments were performed in the rat CUMS model. CUMS rats were treated with Wuling mycelia powder (0.5, 1.0 or 2.0 g/kg, i.g.) to test behavioral changes including the sucrose preference, the crossing number and food consumption. Further, L-arginine (substrate for nitric oxide) (750 mg/kg), 7-nitroindazole (a specific neuronal nitric oxide synthase inhibitor) (25 mg/kg), sildenafil (phosphodiesterase 5 inhibitor) (5 mg/kg) and methylene blue (direct inhibitor of both nitric oxide synthase and soluble guanylate cyclase) (10 mg/kg) were treated for 60 min before each test to detect the possible mechanism of antidepressant-like effect of Wuling mycelia powder.

This novel study evaluated the effects of vardenafil and sildenafil on QT and corrected QT (QTc) duration using a model that minimizes experimental error to obtain the most accurate assessment of observed QTc effects. A placebo-controlled and positive-controlled, period-balanced, double-blinded, 6-way crossover study evaluated therapeutic and supratherapeutic oral doses of vardenafil (10 and 80 mg, respectively) and sildenafil (50 and 400 mg, respectively), therapeutic doses of moxifloxacin (400 mg), and a placebo in 58 healthy men (mean age 53 years), with dosing every 3 days. Six replicate, 12-lead, digital electrocardiograms (ECGs) were recorded at 3 time points before and 5 time points after dosing to cover the time course of maximum exposure to study drugs and their metabolites. An independent laboratory blindly analyzed approximately 17,000 ECGs. For the placebo, mean change in QTcF (Fridericia) duration 1 hour after dose (approximate Tmax of vardenafil and sildenafil) was 0 ms (+/-0.7 SD). QT/QTc variability was small across regimens, indicating statistically powerful results. Moxifloxacin demonstrated an expected 8-ms mean change and was the only drug to prolong absolute QT. Placebo-corrected mean changes in QTcF duration (90% confidence interval) at 1 hour after dose were 8 ms (range 6 to 9) for vardenafil 10 mg and 6 ms (range 5 to 8) for sildenafil 50 mg. QTci (linear and nonlinear per patient) yielded similar trends: 4 ms (range 3 to 6) for vardenafil 10 mg and 4 ms (range 2 to 5) for sildenafil 50 mg. Dose response demonstrated very shallow QTc relations for study drugs. Therapeutic and supratherapeutic doses produced only small increases in the QTcF interval, which were considered to be clinically irrelevant. This well-controlled, statistically powerful study in middle-aged men demonstrated that vardenafil and sildenafil produced no increase of absolute QT and only similar, small increases of the QTc interval, with a shallow dose-response curve. The study design and conduct may serve as a guide for future QT assessment of new drugs.

Ninety-two patients constituted the study population. Mean patient age and duration post-RP at commencement of the rehabilitation program were 59 +/- 10 years and 7 +/- 3 months, respectively. Sixty-seven percent of operations were bilateral nerve sparing (BNS), 11% unilateral nerve sparing (NS), and 22% non-NS. Comorbidities included hypertension 22%, dyslipidemia 30%, coronary artery disease 7%, and diabetes 2%. Preoperative mean self-reported, partner-corroborated erectile rigidity during relations was 90 +/- 20%. At 18 months post-RP, 57% patients had partner-corroborated functional erections without phosphodiesterase type 5 inhibitors with a mean erectile rigidity during relations of 72 +/- 16% compared with 45 +/- 22% for those who denied functional erections postoperatively (P > 0.01). The IIEF-EF domain scores in these two cohorts were 21 +/- 7.5 and 13 +/- 9, respectively (P > 0.01). On multivariate analysis, factors that predicted failure of return of natural erections after RP having followed a rehabilitation program were age >60 years (relative risk [RR] = 1.3), non-BNS surgery (RR = 1.6), presence of >1 vascular comorbidity (RR = 2.1), commencement of rehabilitation >6 months post-RP (RR = 2.8), unsuccessful response to sildenafil at 12 months post-RP (RR = 4.5), and the use of trimix dose >50 units (RR = 8.1).

Recent studies suggest that erectile dysfunction (ED) may be an early marker of endothelial dysfunction and coronary artery disease (CAD). Conversely, patients with CAD commonly have ED. The phosphodiesterase 5 (PDE5) inhibitors are very effective for the treatment of ED in patients with CAD. Numerous studies show that this class of drugs is in general safe in patients with stable CAD and these agents do not exacerbate ischemia in men with CAD undergoing exercise stress testing. Analysis of placebo-controlled trials did not show an increase in cardiovascular events among men receiving PDE5 inhibitors, and post-marketing surveillance studies with sildenafil did not observe an increase in cardiovascular events compared to expected age-matched rates. Organic nitrates remain a contraindication for PDE5 inhibitors and alpha blockers have precautions/contraindications depending upon specific drugs. The Princeton Consensus Guidelines (soon to be updated) suggest a logical approach to the patient with CAD seeking therapy for sexual dysfunction.

Sildenafil (Viagra) is a selective inhibitor of the cyclic guanosine monophosphate (cGMP) specific phosphodiesterase 5 (PDE5) used for the oral treatment of male erectile dysfunction due to vasodilation. However, assessment of direct effects of sildenafil on cerebral arteries is unknown. The aim of this present experiment is to measure the possible changes in blood flow velocity of the middle cerebral artery after the administration of sildenafil and a placebo. Blood-flow velocity changes of the middle cerebral artery were measured before and 1 to 2 h after the administration of the drug. Neither the intake of sildenafil nor the application of placebo resulted in any significant changes in blood flow velocity of the right middle cerebral artery. The next step for future experiments will be in vitro measurement of the diameters of the cerebral arteries under the influence of sildenafil and in vivo measurement of carbon dioxide and cerebral blood flow velocity during sexual stimulation after sildenafil intake instead of under resting conditions.

Three different phosphodiesterase 5 (PDE5) inhibitors are currently available for the treatment of erectile dysfunction: sildenafil, vardenafil and tadalafil. The differences between these 3 are limited: tadalafil has a long duration of action, while vardenafil has a rapid onset of action after intake. Various studies have suggested that there is an improvement in the partners' sex lives when men use a PDE5 inhibitor for erectile dysfunction. The introduction of PDE5 inhibitors has renewed the interest in PDE inhibitors in general, for example in the treatment of pulmonary hypertension. In the near future PDE inhibitors may be used for various disorders as chronic obstructive pulmonary disease, benign prostatic hyperplasia, hypertension and coronary heart disease.

To examine the effect of sildenafil on erectile dysfunction (ED) and psychosocial outcomes in alcohol-dependent (AD) men, 108 men with these diagnoses were randomly assigned to either take sildenafil (50 mg) as add-on to standard treatment for AD, or the same treatment without sildenafil, for 12 weeks. Only 50 patients in sildenafil group and 51 in control group twice completed the International Index of Erectile Function (IIEF) and a battery of self-report questionnaires. IIEF scores and psychosocial functioning, self-esteem and support from friends improved only for sildenafil-treated patients (P < 0.001). The high effect sizes suggest that the observed benefits are unlikely to be a placebo effect, although their unspecific nature could not be ruled out. In men with ED associated with AD, sildenafil improves both ED and psychosocial outcomes. Further placebo-controlled clinical trial is warranted.

All patients completed the study and statistically significant improvement was observed in all evaluated domains of sexual functioning: erectile function (53.5%), orgasmic function (40.3%), sexual desire (53%), intercourse satisfaction (82%) and overall satisfaction (57.4%). Oral sildenafil treatment appeared to be well tolerated and no single patient stopped the treatment. Improvements in various CAPS subscales were also obtained; however, there was no significant correlation between improvement in sexual functioning and the changes in CAPS subscale scores.

Subsarcolemmal cGMP signals were monitored in adult rat cardiomyocytes by expression of the rat olfactory cyclic nucleotide-gated (CNG) channel alpha-subunit and recording of the associated cGMP-gated current (ICNG). Atrial natriuretic peptide (10 nmol/L) or brain natriuretic peptide (10 nmol/L) induced a clear activation of ICNG, whereas NO donors (S-nitroso-N-acetyl-penicillamine, diethylamine NONOate, 3-morpholinosydnonimine, and spermine NO, all at 100 micromol/L) had little effect. The ICNG current was strongly potentiated by nonselective PDE inhibition with isobutyl methylxanthine (100 micromol/L) and by the PDE2 inhibitors erythro-9-(2-hydroxy-3-nonyl)adenine (10 micromol/L) and Bay 60-7550 (50 nmol/L). Surprisingly, sildenafil, a PDE5 inhibitor, produced a dose-dependent increase of I(CNG) activated by NO donors but had no effect (at 100 nmol/L) on the current elicited by atrial natriuretic peptide.

Arterial hypertension is associated with structural and functional alterations of the vessel walls. Because vascular endothelium plays a central role in the control of vascular tone, endothelial dysfunction can also cause certain types of erectile dysfunction. Erectile dysfunction is also a common side effect of certain drugs, including many antihypertensive agents. Physicians should be aware of potential sexual side effects of such drugs and take appropriate steps to alleviate persistent problems. Most important, physicians need to ask patients about sexual function and discuss the possibility of erectile dysfunction caused by antihypertensive therapy. Erectile dysfunction can be effectively treated in most patients, and many treatment options are available. Sildenafil therapy has revolutionized the management of this disorder, but this agent should be used with caution in certain patients taking nitrates.

Dependence was induced by repeated treatments with morphine over 5 consecutive days. The morphine-dependent mice received sildenafil (1, 5, 10, or 20 mg/kg, i.p.) 15 min prior to the precipitation of morphine withdrawal. On the last day, naloxone was injected 2 hours after the last morphine injection, and withdrawal signs were evaluated for 30 min after naloxone injection.

From 2001 to 2005, WHO class II to IV patients were treated with bosentan or prostanoids. In July 2005, a target 6MWD strategy was adopted. Monotherapy continued if 6MWD remained >350 m. For patients in whom 6MWD was ≤350 m, sildenafil was added. If 6MWD remained <350 m, prostanoids were considered. Changes in 6MWD, WHO class and survival rate were compared between periods.

During the last decade new approaches to the treatment of pulmonary arterial hypertension (PH) have increased symptomatic relief and prolonged survival. PH is a common sequel of the hemoglobinopathies, thalassemia and sickle cell anemia, but the use of standard oral treatment options, such as calcium channel blockers, endothelin receptor antagonists, and long-term anticoagulation therapy, is limited because of toxicity and poor effectiveness. Sildenafil citrate is a selective and potent inhibitor of cGMP-specific phosphodiesterase-5 (PDE5) which promotes selective smooth muscle relaxation in lung vasculature and has been utilized successfully in the treatment of PH. The primary objective of this study was to evaluate the efficacy of sildenafil treatment in the control of PH in patients with hemoglobinopathies.

The aim of this study was to evaluate the relaxant effect of taurine, one of the most commonly employed dietary supplements, in rat corpus cavernosum (CC), and to further investigate the contribution of possible underlying mechanisms. Strips of CC were suspended in an organ bath system for isometric tension studies. Taurine (10-80 mmol/l) produced a concentration-dependent relaxation response in rat CC. Endothelial removal did not cause a significant inhibition of the relaxation response to taurine. Incubation of endothelium-denuded CC strips with the nonselective potassium channel blocker tetraethylammonium (10 mmol/l), the ATP-sensitive potassium (KATP) channel blocker glibenclamide (10 μmol/l), the inward rectifier potassium (Kir) channel inhibitor barium chloride (30 μmol/l), and the large conductance calcium-activated potassium channel inhibitor iberiotoxin (0.1 μmol/l) significantly inhibited the relaxant responses to taurine. However, taurine-induced relaxation was not inhibited by the voltage-dependent potassium channel inhibitor 4-aminopyridine (1 mmol/l). On the other hand, taurine (20 mmol/l, 30 min) inhibited both intracellular and extracellular calcium-dependent contraction in CC strips. These findings suggest that taurine induced relaxation of CC via an endothelium-independent pathway. The activation of KATP channels, Kir channels and calcium channels is thought to play an important role in endothelium-independent relaxation of CC, but other direct effects on calcium dynamics may also contribute to its relaxant effect.

Erectile dysfunction (ED) is a common sequel of pelvic fracture urethral disruption. Those patients with nocturnal erections may respond favourably to sildenafil; however, little is known about the response to sildenafil in patients with absent nocturnal erections. The aim was to evaluate the response to the treatment of sildenafil 50 mg taken once daily in the patients with absent nocturnal erections. From January 2008 to December 2011, a total of 28 patients with absent nocturnal erections were evaluated. We recorded nocturnal penile tumescence and rigidity with an erectometer. If nocturnal erections were absent for three nights, patients were administrated sildenafil 100 mg at bedtime and tested again at the fourth night. Penile duplex ultrasound with intracavernous injection was performed to define the cause of ED. All patients received a daily dose of sildenafil 50 mg for 12 weeks. Response to sildenafil treatment was defined as sustained erections allowing vaginal penetration and intercourse. Twenty-three (78%) patients completed the daily sildenafil treatment, and follow-up was available. The nocturnal erections at the fourth night in 13 patients (46.4%) were improved. About 61.5% (8/13) reported effective response to daily sildenafil. The improvement of nocturnal erections induced by sildenafil taken at bedtime might predict the response to sildenafil taken daily.

Sildenafil and other PDE-5 inhibitors have revolutionized erectile dysfunction (ED) treatment. However, a significant number of patients do not respond or present adverse reactions to these drugs. While genetic polymorphisms may underlie this phenomenon, very little research has been undertaken in this research field. Most of the current knowledge is based on sildenafil, thus almost completely ignoring other important pharmacological therapies. Currently, the most promising genes with pharmacogenetic implications in ED are related to the nitric oxide and cGMP pathway, although other genes are likely to affect the responsiveness to treatment of ED. Nevertheless, the small number of studies available opens the possibility of further exploring other genes and phenotypes related to ED. This article provides a comprehensive overview of the genes being tested for their pharmacogenetic relevance in the therapy of ED.

Phosphodiesterase-5 (PDE-5) inhibitors are an effective therapy for the majority of men with erectile dysfunction (ED). However, many men with ED still report a suboptimal or partial response even after an adequate trial of oral PDE-5 therapy. Since ED is associated with impaired vascular function and both atorvastatin and quinapril have been previously shown to improve vascular function, we examined the effects of adjunctive treatment with these medications in men with vasculogenic ED who were suboptimal responders to 100 mg of sildenafil. Men with ED and suboptimal response to sildenafil were randomly assigned to 3 months of treatment with atorvastatin 40 mg (n = 12), quinapril 10 mg (n = 10), or placebo (n = 13), along with continued adjunctive sildenafil use. Measured variables included: International Index of Erectile Function (IIEF) questionnaire, brachial artery flow-mediated dilation (FMD), endothelium-independent dilation (EID) via nitroglycerin, penile Doppler blood flow, blood pressure (BP), lipids, and C-reactive protein (CRP). Compared to placebo, quinapril (p < 0.01) significantly improved symptoms of ED as measured by the IIEF-5 questionnaire. There was a trend toward a significant improvement in IIEF-5 with atorvastatin. Similarly, quinapril significantly improved the IIEF ED Domain (p < 0.05). Other peripheral and penile vascular parameters were unchanged with drug therapy as compared to placebo. In conclusion, treatment with quinapril, in combination with sildenafil, improved ED in men with suboptimal response to sildenafil alone. Atorvastatin demonstrated a trend toward improved ED in this group.

Erectile dysfunction is a prevalent and distressing problem. The availability of sildenafil citrate has significantly altered the way in which erectile dysfunction is treated. While this medication is extremely effective in restoring erectile function, it is often necessary to ensure that the partner is actively involved in treatment since many men are in relationships characterized by sexual apathy and avoidance as well as relationship conflict. These problems, if left untreated, can thwart the transition from sexual abstinence to sexual intimacy.

Sildenafil citrate (SIL) is used in the treatment of erectile dysfunction and other chronic disorders. For the pharmacokinetic investigation of SIL we developed a simple and sensitive method for the estimation of SIL in rat plasma Topamax 800 Mg by reverse phase high-performance liquid chromatography (RP-HPLC). The drug samples were extracted by liquid-liquid extraction with 300 μl of acetonitrile and 5 ml of diethyl ether. Chromatographic separation was achieved on C18 column using methanol:water (85:15 v/v) as mobile phase at a flow rate of 1 ml/min and UV detection at 230 nm. The retention time of SIL was found to be 4.0 min having a separation time less than 5 min. The developed method was validated for accuracy, precision, linearity and recovery. Linearity studies were found to be acceptable over the range of 0.1-6 μg/ml. The method was successfully applied for the analysis of rat plasma sample for the application in pharmacokinetic study, drug interaction, bioavailability and bioequivalence.
