Description

Uses of Sildenafil Citrate

Sildenafil citrate is used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). It is also used to relax the muscles in the walls of the blood vessels in the penis, allowing blood to flow more easily during sexual stimulation.

ED and PAH are conditions that occur when blood is not adequately flowing freely in the penis. ED occurs when blood is not able to flow freely enough to enable sexual stimulation, leading to ED.

The condition can also be caused by a condition called vasculogenic pulmonary hypertension (VPH). VPH is a condition where the blood flow is blocked by a thickening of the blood vessels in the lungs, resulting in an overactive and narrowed blood supply. Sildenafil citrate works by relaxing the smooth muscles in the walls of the blood vessels, allowing blood to flow more easily during sexual stimulation.

ED can occur in men or women and is usually triggered by stress, certain medical conditions, or certain medications. It can be a result of a physical problem, psychological factors, or both.

The use of sildenafil citrate may be associated with side effects such as dizziness, headache, and vision problems. It may also cause an enlarged prostate, a rare but serious condition in which a gland becomes large and painful.

If you experience side effects such as erectile dysfunction, persistent headache, or a persistent erection that lasts longer than four hours, contact a doctor immediately.

If you experience persistent or severe ED, or if the symptoms worsen over time, it is recommended to consult a doctor.

How Sildenafil Citrate Works

Sildenafil citrate works by blocking the effects of phosphodiesterase type 5 (PDE5). This enzyme is responsible for breaking down cyclic guanosine monophosphate (cGMP), a substance in the body that relaxes the smooth muscles in the blood vessels of the penis.

cGMP is responsible for relaxing the smooth muscles in the blood vessels of the penis. cGMP then causes the relaxation of the smooth muscles in the corpus cavernosum and causes increased blood flow into the penis.

This increased blood flow causes the smooth muscles in the corpus cavernosum to relax, thereby helping to achieve an erection. Sildenafil citrate does not increase sexual desire. It only works by blocking the action of PDE5. It does not affect sexual desire.

Sildenafil citrate does not cause an erection on its own. It does not cure ED. However, it helps to increase blood flow into the penis and has a longer duration of action.

Dosage and Administration

The dose and administration of sildenafil citrate may vary depending on the condition being treated and the age, gender, and overall health of the patient.

The usual dosage is one 100 mg tablet taken orally once a day.

Sildenafil citrate is taken orally as a single tablet. It is not to be taken with a full glass of water.

For men with an enlarged prostate, the usual dosage is one 50 mg tablet taken orally 1-3 hours before sexual activity.

For women with a normal amount of semen, the usual dosage is one 50 mg tablet taken orally once a day.

For men with both ED and VPH, the usual dosage is one 100 mg tablet taken orally once a day.

In addition, the following should be kept in mind when using sildenafil citrate:

  • Do not take sildenafil citrate if you are taking nitrates or alpha-blockers (used for chest pain)
  • Do not take sildenafil citrate if you have taken nitrates for chest pain or have had a stroke

Sildenafil (Generic Viagra) is a phosphodiesterase type 5 (PDE5) inhibitor for the treatment of erectile dysfunction (impotence). In addition to the primary use of this medication, sildenafil has also been used off-label for pulmonary arterial hypertension and other cardiovascular disease. This medication may also be used for pulmonary hypertension. The efficacy and safety of sildenafil in treating pulmonary arterial hypertension were established in a double-blind placebo-controlled clinical trial. The patients were randomized to receive sildenafil (50 mg) or placebo for six weeks. The primary efficacy endpoint was the change from baseline in total PDE5 activity in the right ventricular wall. Secondary endpoints included change from baseline in total PDE5 activity, intravascular PDE5, and vascular PDE5. The incidence of adverse events was similar between the two groups.

Pulmonary Arterial Hypertension

Sildenafil is FDA approved to treat pulmonary arterial hypertension in adults, but the drug is not prescribed for children aged < 6 years.

Dosage in Canada:The recommended starting dose of sildenafil in adult patients is 25 mg to 50 mg twice daily. The maximum daily dose for adult patients is 100 mg. Patients taking sildenafil at any time of the day should be treated with the lowest dose that is effective for the shortest duration needed to achieve and maintain desired therapeutic effects. The dosage regimen of sildenafil in adult patients should be adjusted in order to be as effective in achieving desired results.

Dosage in the United States:The recommended starting dose of sildenafil for adult patients is 50 mg taken once daily, with or without food.

The efficacy of sildenafil for pulmonary arterial hypertension

The efficacy of sildenafil for pulmonary arterial hypertension was established in a double-blind, placebo-controlled clinical trial. The patients were randomized to receive sildenafil (100 mg) or placebo for six weeks.

The incidence of adverse events was also similar between the two groups.

The mean daily dose of sildenafil was 50 mg. There was no difference in the incidence of adverse events between the two groups.

In addition, the mean daily dose of sildenafil in the placebo group was lower than in the sildenafil group at six weeks. However, the difference did not reach statistical significance. Therefore, sildenafil is not recommended for patients taking this medication.

Safety Profile

In a double-blind, placebo-controlled trial, the primary safety endpoint was change from baseline in hemoglobin, hematocrit, and oxygen saturation, and was improved with sildenafil compared to placebo. Secondary endpoints were hemoglobin at six weeks, hematocrit at six months, and oxygen saturation at six months.

In a double-blind, placebo-controlled study, the primary safety endpoint was the change from baseline in hemoglobin, hematocrit, and oxygen saturation, and was improved with sildenafil compared to placebo.
