Viagra Information

Viagra (Sildenafil) is primarily used for the treatment of erectile dysfunction in men. Sildenafil could also be used to treat pulmonary arterial hypertension. The active ingredient is sildenafil citrate, a phosphodiesterase type 5 inhibitor. This medication works by blocking the phosphodiesterase type 5 enzyme, which breaks down cyclic guanosine monophosphate (cGMP). When this enzyme is inhibited, cGMP levels remain elevated in smooth muscle cells of blood vessels. This causes the smooth muscles to relax and the vessels to dilate, increasing blood flow to specific areas of the body or reducing blood pressure in the lungs.

Erectile dysfunction is a condition where a person cannot get or keep an erection, often because the blood vessels in the penis do not stay open long enough. In this condition, sildenafil helps by keeping those vessels relaxed, which is likely to support the blood flow needed for an erection during sexual stimulation. Pulmonary arterial hypertension is a different condition where the blood pressure in the arteries that carry blood to the lungs is abnormally high. This high pressure makes the heart work much harder than it should to move blood. By relaxing these specific vessels in the lungs, sildenafil lowers the pressure. This process appears to make it easier for the heart to pump blood, which often helps the person feel less short of breath and increases their capacity for physical activity. Sildenafil is especially useful in treating patients diagnosed with Group 1 pulmonary arterial hypertension, a disease process, according to the World Health Organization, characterized by a condition that primarily affects the small arteries and arterioles in the lungs.

Sildenafil may cause dizziness or temporary vision changes, which can affect your ability to drive or operate machinery. Avoid driving, operating machinery, or performing other potentially hazardous tasks until you have determined how this medication affects you. Consult your doctor before using this medication during pregnancy or while breastfeeding to help determine its risk and benefits for your condition and your baby. Sildenafil should not be given to children younger than 1 year, as its safety has not been established in this age group. Taking sildenafil with some other medications, such as riociguat, nitrate-containing drugs, can increase the risk of severe low blood pressure. Therefore, before taking this medication, inform your doctor about any other medications you are currently taking, including herbal medicines, to determine if it is safe to use along with sildenafil.

Taking a single dose roughly an hour before sex usually provides the most effective results for erectile dysfunction. High-fat meals might delay the onset, so a lighter meal is likely a better choice. Do not take grapefruit or grapefruit-containing juice while taking this medication, as they can alter the effects of this drug in the body. You should swallow the tablet whole with a glass of water. Consult your doctor for the appropriate dose for you, as it usually depends on the conditions you are being treated for, your age, body weight, response to treatment, and other factors. Check out the leaflet in the medication pack for more usage instructions. Store this medication at room temperature and keep it away from sunlight, moisture, and out of children's reach.
