Inventum

Sildenafil citrate, the active ingredient in Inventum, is a phosphodiesterase type 5 inhibitor presented as an oral tablet for oral use. It is prescribed to treat erectile dysfunction in adult males and to improve exercise capacity in patients with pulmonary arterial hypertension.

GNH USA supplies Inventum as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, ensuring quality and regulatory compliance across all markets. The company follows stringent Good Distribution Practice standards and provides reliable logistics for timely delivery.

Inventum (sildenafil citrate) acts on the nitric‑oxide/cGMP pathway to address conditions related to vascular smooth‑muscle tone.

Erectile dysfunction: enhances ability to achieve and maintain an erection sufficient for sexual activity. Pulmonary arterial hypertension: improves exercise capacity and reduces pulmonary vascular resistance in affected patients. Sexual dysfunction associated with certain medical conditions: assists in achieving satisfactory sexual performance when underlying disease contributes to erectile issues.

Sildenafil citrate may be associated with a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Headache - Facial flushing - Dyspepsia or indigestion - Nasal congestion - Visual disturbances (e.g., blurred vision) - Back pain or muscle aches

Serious or Rare Side Effects: - Priapism (prolonged erection) - Sudden hearing loss - Severe hypotension - Myocardial infarction or acute coronary syndrome - Stroke or transient ischemic attack - Vision loss due to retinal vascular events

When prescribing Inventum, clinicians should consider several safety measures. - Cardiovascular assessment: evaluate the patient’s ability to engage in sexual activity and screen for recent myocardial infarction. - Concurrent nitrate therapy: avoid use due to risk of severe hypotension. - Use in patients with severe renal or hepatic impairment: dose adjustment may be required. - Monitor for visual changes: discontinue if sudden loss of vision occurs. - Avoid use in patients with known hypersensitivity to sildenafil. - Store at ambient temperature below 25°C: keep in the original pack, protect from moisture and light.

Sildenafil citrate can interact with several medicines, requiring careful management.

Major Interactions (Avoid): - Nitrates (e.g., nitroglycerin, isosorbide dinitrate) - Guanylate cyclase stimulators (e.g., riociguat) - Nitric oxide donors used for pulmonary hypertension - Other phosphodiesterase‑5 inhibitors (e.g., tadalafil, vardenafil)

Moderate Interactions (Monitor Closely): - Alpha‑blockers (e.g., tamsulosin) - Antihypertensive agents (may enhance blood‑pressure lowering) - Strong CYP3A4 inhibitors (e.g., erythromycin, ketoconazole) - CYP3A4 inducers (e.g., rifampin, carbamazepine) - Protease inhibitors (e.g., ritonavir) which can increase sildenafil exposure
