Descriptions

Sildenafil is used to treat men who have erectile dysfunction (also called sexual impotence). Sildenafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly. The penis is one of the areas where this enzyme works.

Erectile dysfunction is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. When a man is sexually stimulated, his body’s normal response is to increase blood flow to his penis to produce an erection. By controlling the enzyme, sildenafil helps to maintain an erection after the penis is stroked. Without physical action to the penis, such as that occurring during sexual intercourse, sildenafil will not work to cause an erection.

Sildenafil is also used in both men and women to treat the symptoms of pulmonary arterial hypertension. This is a type of high blood pressure that occurs between the heart and the lungs. When hypertension occurs in the lungs, the heart must work harder to pump enough blood through the lungs. Sildenafil works on the PDE5 enzyme in the lungs to relax the blood vessels. This will increase the supply of blood to the lungs and reduce the workload of the heart.

Sildenafil Dosage

Sildenafil is the active ingredient in Viagra. It causes the release of nitrous oxide (NO), a chemical that enlarges the blood vessels in the penis during sexual stimulation. This allows for the necessary inflow of blood needed to cause an erection.

Sildenafil Dosage 100mg, 50mg and 25mg

The Sildenafil dosage you need to take will depend on your age, gender, medical condition, your response to therapy and use of any interacting medication. 25, 50 and 100mg Sildenafil tablets are available. The recommended dose for most people is 50mg taken between 30 minutes and four hours prior to sexual activity. This dose can be increased to 100 or decreased to 25mg depending on adverse effects and efficacy. Ideally, it should be taken on an empty stomach. If you take Sildenafil after eating, it will take longer to kick in. Your tablet should be swallowed whole with a drink of water. Sildenafil should not be taken more than once in a day.

Drinking grapefruit juice while using this medication can be dangerous. It may increase the drug’s concentration in your blood, causing more pronounced Sildenafil side effects.

The following patients should stick to 25mg Sildenafil tablets:

  • anyone over 65 years of age
  • with liver failure
  • with creatinine clearance <30ml/min
  • using potent cytochrome P450 inhibitors
