Mysildecard (Sildenafil)

Sildenafil, the active ingredient in Mysildecard, is a phosphodiesterase type 5 (PDE5) inhibitor presented as an oral tablet for oral use. It treats erectile dysfunction in men and pulmonary arterial hypertension by enhancing nitric‑oxide mediated vasodilation in the corpus cavernosum and pulmonary vasculature.

GNH USA supplies Mysildecard as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Mysildecard (sildenafil) is used in conditions that involve impaired nitric‑oxide mediated vasodilation, primarily within the erectile and pulmonary circulations.

- Erectile dysfunction: improves the ability to achieve and maintain an erection suitable for sexual activity. - Pulmonary arterial hypertension: lowers pulmonary arterial pressure, improves exercise capacity and reduces disease progression.

Common Side Effects: - Headache: mild to moderate pain often occurring shortly after dosing. - Flushing: warmth and redness of the face or upper body. - Dyspepsia: indigestion or stomach discomfort. - Nasal congestion: feeling of a blocked nose.

Serious or Rare Side Effects: - Priapism: prolonged erection lasting more than four hours, requiring urgent medical attention. - Sudden vision loss: abrupt loss of vision in one or both eyes, possibly indicating non‑arteritic anterior ischemic optic neuropathy. - Sudden hearing loss: rapid decrease or loss of hearing, sometimes accompanied by tinnitus.

Before initiating therapy, consider the following precautions: - Cardiovascular assessment: evaluate for recent myocardial infarction, unstable angina, or severe heart failure. - Nitrate use: avoid concurrent administration with any nitrate medication due to risk of severe hypotension. - Hepatic impairment: use with caution in patients with moderate to severe liver disease. - Visual changes: monitor for any sudden loss of vision or color perception. - Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Sildenafil may interact with several medicines; review patient medication lists carefully.

Major Interactions (Avoid): - Nitrates: concurrent use can cause profound hypotension and syncope. - Guanylate cyclase stimulators (e.g., riociguat): combined effect may lead to dangerous blood‑pressure drops.

Moderate Interactions (Monitor Closely): - Alpha‑blockers: may enhance blood‑pressure lowering effects. - Strong CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): increase sildenafil plasma concentrations. - CYP3A4 inducers (e.g., rifampin, carbamazepine): reduce sildenafil effectiveness.
