Granpidam

Granpidam is a prescription medication that contains the active ingredient sildenafil, a phosphodiesterase type 5 inhibitor, supplied in oral tablet form; the specific strength is not disclosed in the available product information. It is marketed within the European Union and is classified as a prescription‑only drug for the treatment of certain vascular conditions. It is intended for adult patients and should be used under medical supervision.

Granpidam is indicated for specific medical conditions where increased blood flow is beneficial.

- Treatment of erectile dysfunction in adult males. - Management of pulmonary arterial hypertension to improve exercise capacity. - Adjunct therapy for certain cases of benign prostatic hyperplasia‑related lower urinary tract symptoms (off‑label use in some regions). - Use in clinical studies evaluating vascular endothelial function. - Support of right‑ventricular function in patients with chronic heart failure (investigational). - Potential benefit in high‑altitude pulmonary edema under specialist guidance.

Side effects reported with sildenafil‑containing products vary in frequency and severity.

Common: - Headache. - Flushing. - Nasal congestion. - Dyspepsia or upset stomach. - Visual disturbances such as blurred vision or a blue tint. - Muscle aches or back pain.

Serious: - Sudden loss of vision (non‑arteritic anterior ischemic optic neuropathy). - Sudden hearing loss or ringing in the ears. - Priapism (prolonged erection lasting more than 4 hours). - Severe allergic reactions including rash, swelling, or difficulty breathing.

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

- Cardiovascular disease, especially recent myocardial infarction or unstable angina, may increase risk. - Concomitant use of nitrates or nitric oxide donors is contraindicated due to severe hypotension. - Patients with severe liver or kidney impairment may require dose adjustment or monitoring. - History of retinal disorders, such as retinitis pigmentosa, should be disclosed. - Use is not recommended in individuals with known hypersensitivity to sildenafil or any tablet excipients. - Caution is advised in patients taking alpha‑blockers for prostate enlargement or hypertension.

Granpidam can interact with other medicines, affecting its safety or effectiveness.

Avoid: - Nitrates (e.g., nitroglycerin, isosorbide dinitrate) – risk of dangerous blood pressure drop. - Recreational drugs containing poppers (amyl nitrite) – may cause severe hypotension. - Certain antifungal agents (ketoconazole, itraconazole) – increase sildenafil plasma levels. - Some antibiotics (e.g., clarithromycin, erythromycin) – may elevate drug concentrations.

Use with caution: - Alpha‑blockers (e.g., tamsulosin, doxazosin) – monitor for additive blood pressure effects. - Antihypertensive medications – adjust dose if excessive hypotension occurs. - Protease inhibitors used in HIV therapy – may require dose reduction. - Diuretics – watch for dehydration and blood pressure changes.
