Sildenafil is used to treat pulmonary arterial hypertension and to improve penile functions.
Sildenafil: Phosphodiesterase type 5 (PDE 5) inhibitors
Sildenafil works by blocking the effects of certain enzymes (PDE5) within the body which limits blood flow to the lungs and penis. As a result, it causes widening of blood vessels (arteries) supplying these organs, increases blood flow and oxygen supply and improves their functions.
Consult your doctor if you experience:
Sildenafiliharalike side effects, such as dizziness, fainting, lightheadedness, a fast heartbeat, and blurred vision, can be more than welcome, but it is not suitable for everyone.

The US Food and Drug Administration’s approval of sildenafil citrate as an oral medication for the treatment of pulmonary arterial hypertension has been a major turning point in the realm of erectile dysfunction, and its approval by the FDA has led to a significant reduction in the prevalence of the condition.
While the exact mechanism of action for sildenafil remains unknown, a potential risk to patients may be that sildenafil, or any related medication, can potentiate certain side effects of the drug. This is because the nitric oxide-specific phosphodiesterase type 5 (PDE5) enzyme, which is the predominant phosphodiesterase enzyme in the body, is also present in the smooth muscle cells of pulmonary arteries.
In other words, sildenafil can interact with nitric oxide, potentially reducing the effects of nitric oxide by increasing the concentration of this enzyme, and in turn, increasing the level of its levels, or both, in the blood. The latter effect is thought to be responsible for the increased risk of adverse events including sudden cardiac death, sudden pulmonary edema, and sudden loss of consciousness in patients with heart failure.
In a study of patients with pulmonary arterial hypertension and sildenafil use, the use of sildenafil citrate was associated with a significantly increased rate of myocardial infarction and death. Other, potentially more serious, adverse events were observed in the group treated with sildenafil citrate, including an increased incidence of pulmonary hypertension, hypertension, and hypotension.
It is possible that the use of sildenafil may also induce the formation of nitric oxide, a nitric oxide-dependent molecule, that is essential for the action of sildenafil. Since nitric oxide-dependent phosphodiesterase enzymes are found in the smooth muscle of pulmonary arteries, their inhibition by sildenafil can also increase the concentrations of the latter, and the latter may be involved in the vasodilation effects observed in some patients.
Sildenafil is a selective inhibitor of the phosphodiesterase type 5 (PDE5) enzyme, and its inhibition by sildenafil may cause a greater degree of vasodilation in the pulmonary vasculature than in the systemic circulation. This has implications for the clinical management of erectile dysfunction, as it may lead to the worsening of the condition.
It should be noted that the incidence of these adverse events in the sildenafil group is lower than that reported in other patients with pulmonary arterial hypertension.
It should be noted that while the clinical use of sildenafil has been associated with an increased incidence of adverse events in some patients with pulmonary arterial hypertension, this has not been consistently reported in the same patient group. It is likely that the clinical use of sildenafil, or any related medication, may have been associated with a different degree of cardiovascular risk.
As with any medication, sildenafil can interact with other drugs, including nitrates, which are often used to treat angina (chest pain).
For those who may be concerned about the potential for sildenafil to induce a sudden cardiac event, the potential risk for this interaction may be greater in those who are taking nitrates (e.g., nitroglycerin) in addition to sildenafil. This is because the effects of nitrates, which are generally used to treat angina, may be more pronounced in patients with severe heart or liver disease.
It should be noted that the interaction between sildenafil and nitrates can be dangerous for patients with preexisting heart disease or low blood pressure. If you experience chest pain while taking sildenafil, you should seek immediate medical attention.
For those who are considering taking sildenafil and are concerned about the potential for interaction between sildenafil and nitrates, please read our article, “What You Should Know about Sildenafil and Nitrates in Your Patient”. The article provides a comprehensive look at the interaction between sildenafil and nitrates in the treatment of erectile dysfunction.
Sildenafil citrate, commonly known by the brand name, is a prescription-only medicine used to treat erectile dysfunction (ED) in adult men. It works by improving blood flow to the penis, helping to achieve and maintain an erection during sexual activity.
Sildenafil is available in 25mg, 50mg, and 100mg strengths.
