Granpidam

Granpidam is a prescription medication that contains the active ingredient sildenafil. It is administered orally and is marketed in the European Union. As a phosphodiesterase type 5 (PDE5) inhibitor, Granpidam works by enhancing blood flow in specific tissues. The product is used under medical supervision for conditions that benefit from smooth muscle relaxation and increased cyclic GMP levels.

Granpidam is indicated for several clinical conditions where vasodilation improves symptoms. It is prescribed by qualified healthcare professionals based on individual assessment.

- Treatment of erectile dysfunction in adult males. - Management of pulmonary arterial hypertension to improve exercise capacity. - Adjunct therapy for certain cases of secondary hypertension when other treatments are insufficient. - Off‑label use may be considered for Raynaud's phenomenon under specialist guidance. - May be used in clinical trials evaluating vascular function.

Side effects of Granpidam vary in frequency and severity. Patients should be aware of both common and less frequent reactions.

Common: - Headache - Flushing or warmth sensation - Indigestion or dyspepsia - Nasal congestion - Visual disturbances such as blurred vision

Serious: - Sudden loss of vision (non‑arteritic anterior ischemic optic neuropathy) - Prolonged erection lasting more than 4 hours (priapism) - Severe hypotension, especially when combined with nitrates - Cardiovascular events like myocardial infarction in high‑risk patients - Allergic reactions including rash, itching, or swelling

Before starting Granpidam, certain health considerations should be reviewed with a healthcare provider.

- Assess cardiovascular status, especially recent heart attack or stroke. - Evaluate for concurrent use of nitrates or nitric oxide donors. - Review history of retinal disorders or severe visual impairment. - Consider renal or hepatic impairment, which may affect drug clearance. - Discuss any prior episodes of priapism or prolonged erections. - Inform the prescriber of all current medications, including over‑the‑counter products.

Granpidam can interact with other medicines, influencing its safety and effectiveness.

Avoid: - Nitrates (e.g., nitroglycerin, isosorbide dinitrate) due to risk of severe hypotension. - Guanylate cyclase stimulators (e.g., riociguat) for pulmonary hypertension. - Certain potent CYP3A4 inhibitors (e.g., ketoconazole, itraconazole) that may increase sildenafil levels.

Use with caution: - Alpha‑blockers for prostate enlargement or hypertension. - Antihypertensive agents, especially when blood pressure is already low. - Other PDE5 inhibitors; concurrent use is not recommended. - Grapefruit juice, which can modestly raise drug concentrations.
