Cardiax 20 mg is a pharmaceutical preparation containing 20 mg of sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor used to treat two main conditions: erectile dysfunction (ED) in men and pulmonary arterial hypertension (PAH) in adults. Sildenafil works by increasing levels of cyclic guanosine monophosphate (cGMP), leading to relaxation of smooth muscle in blood vessels. In the case of ED, this results in enhanced blood flow to the penile tissue, helping men achieve and maintain erections when sexually stimulated. For PAH, sildenafil dilates the pulmonary blood vessels, reducing pulmonary vascular resistance and improving the ability to exercise.
In the treatment of erectile dysfunction, the usual adult dose of sildenafil ranges from 25 mg to 100 mg taken about 30 minutes to one hour before sexual activity. Cardiax 20 mg may be prescribed for individuals requiring a lower dose due to age, concomitant medical conditions or medication interactions. For pulmonary arterial hypertension, the recommended dose is typically 20 mg taken three times daily about 4 to 6 hours apart. Patients should follow their healthcare provider’s instructions carefully and should not take more than prescribed. Sildenafil should not be taken with nitrate medications or certain blood pressure medications because the combination can cause a dangerous drop in blood pressure.
Common side effects of Cardiax 20 mg may include headache, flushing, indigestion, nasal congestion, dizziness and visual changes (such as blurred vision or a blue tint). These effects are generally mild and transient. More serious side effects, while rare, include prolonged or painful erections (priapism), sudden vision or hearing loss, and significant drops in blood pressure. Individuals with cardiovascular disease, retinitis pigmentosa or severe liver/kidney disease should consult their doctor before using sildenafil. It is also important to disclose all medications and supplements being taken to avoid potential interactions. Alcohol and grapefruit products should be limited as they may affect how sildenafil is metabolized. Women who are pregnant or breastfeeding and children should not use sildenafil unless prescribed for PAH by a specialist. When used appropriately under medical supervision, Cardiax 20 mg can provide effective treatment for ED or PAH, improving quality of life.
