The following information is provided for clinicians and other healthcare professionals. Viagra is approved to treat erectile dysfunction (ED) in males ages 18 years and older. It should be taken between 30 minutes and 4 hours before planned sexual activity.

Viagra contains sildenafil citrate, an inhibitor of phosphodiesterase type 5 (PDE5).

Viagra enhances the action of cyclic GMP, which is released in the penis in response to sexual stimulation.

Cyclic GMP dilates smooth muscle in the penile tissue. It also increases blood to flow into the corpus cavernosum, causing an erection. Viagra blocks PDE5 from breaking down cyclic GMP, thereby improving the ability to achieve and maintain an erection in response to sexual stimulation.

Sildenafil has an average bioavailability of 41% (ranges from 25% to 63%) after oral administration of Viagra tablets. When taken on an empty stomach, the time to reach peak plasma concentration (Tmax) is approximately 30 to 120 minutes.

Taking Viagra with a high-fat meal delays Tmax by about 60 minutes. It also reduces the maximum plasma concentration (Cmax) by an average of 29%.

Sildenafil is primarily metabolized by hepatic CYP3A4, to a metabolite with similar activity to sildenafil. Sildenafil and its active metabolite have a terminal half-life of approximately 4 hours.

Approximately 80% of the dose is excreted in feces, and approximately 13% is excreted in urine. Reduced clearance of sildenafil is seen in people ages 65 years and over, and in those with hepatic impairment or severe renal impairment.

Viagra is contraindicated in people with a known allergy to sildenafil, or any of the inactive ingredients in Viagra. Viagra is also contraindicated for use in combination with: nitrate drugs in any form, such as: nitroglycerin (Nitromist, Nitro-Dur, Nitrolingual Pumpspray, Gonitro, others) isosorbide mononitrate (Monoket) guanylate cyclase stimulators, such as riociguat (Adempas) Storage. Store Viagra at room temperature between 68 o F and 77°F (20 o C and 25°C).

Sildenafil citrate is a drug commonly used to manage erectile dysfunction.

It is designated chemically as 1-[[3-(6,7-dihydro-1-methyl-7-oxo-3-propyl-1 H -pyrazolo[4,3- d ]pyrimidin-5-yl)-4 ethoxyphenyl] sulfonyl]-4-methylpiperazine citrate (C 22 H 30 N 6 O 4 S). It is a highly selective inhibitor of cyclic guanine monophosphate-specific phosphodiesterase type 5.

In late March through mid-November 1998, the US Food and Drug Administration (FDA) published a report on 130 confirmed deaths among men (mean age, 64 years) who received prescriptions for sildenafil citrate, a period during which >6 million outpatient prescriptions (representing about 50 million tablets) were dispensed. The US FDA recently reported that significant cardiovascular events, including sudden cardiac death, have occurred in men with erectile dysfunction who were taking sildenafil citrate. These reports have raised concerns that sildenafil citrate may increase the risk of cardiovascular events, particularly fatal arrhythmias, in patients with cardiovascular disease.

In the past few years, the cardiac electrophysiological effects of sildenafil citrate have been investigated extensively in both animal and clinical studies. According to extensive data available to date, sildenafil citrate has been shown to pose minimal cardiovascular risks to healthy people taking this drug.

Some precautions are needed for patients with cardiovascular diseases. However, the only absolute contraindication for sildenafil citrate is the concurrent use of nitrates.

This article is intended to review sildenafil citrate's cardiovascular effects, as well as current debates about its arrhythmogenic effects.

Key words: Sildenafil citrate, Erectile dysfunction, Sudden cardiac death, Cardiovascular disease, Phosphodiesterase inhibitor, Cardioprotection.

Sildenafil citrate was the first oral drug approved for the treatment of erectile dysfunction (ED), which is frequently observed in men with cardiovascular disease (1).

ED is defined as the inability to achieve and/or maintain an erection sufficient for satisfactory sexual activity (2).

The prevalence of moderate to complete ED has been reported to be >30% in men aged 40 to 70 years (3).

Since the approval of sildenafil citrate, several reports of sudden death among patients treated with this drug have raised some concerns regarding its safety in patients with coronary artery disease (4). In the past few years, the cardiovascular effects of sildenafil citrate have been investigated extensively in both animal and clinical studies.

In this article we shall review these studies, as well as the current debate about sildenafil citrate's arrhythmogenic effects.

ED is a common health concern among patients with cardiovascular disease. According to the Massachusetts Male Aging Study, 34.8% of men aged 40 to 70 years have moderate to complete ED, and 15% of men aged 70 have complete ED (3).

The risk of ED has been shown to markedly increase with age, with a high prevalence of ED found in patients with cardiovascular disease (3).

Greenstein and colleagues (5) have shown that there is a significant correlation between the severity of ED and the number of vessels involved in patients with coronary artery disease (CAD). The age-adjusted prevalence of complete ED has been reported to be 1.5 times higher in men with hypertension than in the entire population studied (3).

Epidemiologic studies have reported that ED is commonly found in smokers, diabetics and patients with hypercholesterolemia; thus, ED shares important risk factors with CAD (6).

A report by Khan and colleagues (7) also found that patients with CAD and peripheral vascular disease have an increased prevalence of ED. ED is considered to be a significant medical condition because it can lead to a loss of self-esteem, frustration, depression, and difficulty with disruption of sexual relationships (8).

Increasing attention has recently been focused on ED due to the advent of effective oral treatments. Although ED was once diagnosed and treated primarily by urologists, primary care physicians and other specialists such as cardiologists now write. 80% of the prescriptions for sildenafil citrate, the most popular drug used to treat this condition (9). Sildenafil citrate is a useful tool for the treatment of ED because it selectively inhibits phosphodiesterase type 5 (PDE-5) (10), which inactivates cyclic guanine monophosphate (cGMP), the mediator of smooth muscle relaxation in the corpus cavernosum. By selectively inhibiting cGMP catabolism in cavernosal smooth-muscle cells (10), sildenafil citrate can restore the natural erectile response to sexual stimulation without causing erections in the absence of such stimulation. Sildenafil citrate is rapidly absorbed, with maximal plasma concentrations occurring within 1 h after oral administration and a mean terminal half-life of 3 to 5 h (10). Sildenafil citrate has been shown to be an effective treatment for ED.

However, after sildenafil citrate was approved by the US Food and Drug Administration (FDA) in 1998, several deaths were reported in patients taking sildenafil sildenafil citrate 100mg lowest price citrate. It was generally assumed that they were related to an underlying disease (e.g., ischemia) and not to a specific drug effect (11). Nevertheless, these reports raised concerns that sildenafil citrate may increase the risk of cardiovascular events in men with ED and cardiovascular disease (12), which led to many basic and clinical investigations of the adverse cardiovascular effects of this drug (12). Use of sildenafil citrate in patients with cardiovascular disease. Sildenafil citrate is a cGMP-specific PDE-5 inhibitor (10). PDE-5, sildenafil citrate 100mg lowest price which is located primarily in the cavernous body, thrombocytes and vascular smooth muscle cells, degrades cGMP (13).

Thus, by inhibiting PDE-5, sildenafil citrate selectively increases cGMP levels (10).
