Inventum Max

Sildenafil citrate, the active ingredient in Inventum Max, is a phosphodiesterase type 5 (PDE5) inhibitor presented as an oral dosage form for oral use. It is indicated for the treatment of erectile dysfunction in adult males. The medication works by enhancing blood flow to the penis, facilitating erection when sexual stimulation occurs. It is marketed in the European Union and conforms to the relevant quality standards. The product is manufactured under strict GMP conditions to ensure consistent potency and purity.

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

Sildenafil citrate acts on the nitric‑oxide/cGMP pathway to improve erectile function and pulmonary vascular tone.

- Erectile dysfunction: enhances ability to achieve and maintain an erection sufficient for sexual activity. - Pulmonary arterial hypertension: lowers pulmonary arterial pressure and improves exercise capacity in affected patients. - Secondary Raynaud’s phenomenon: may increase blood flow to extremities, reducing frequency of attacks.

Sildenafil citrate may cause a range of adverse reactions, most of which are mild and transient.

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 upset stomach. - Nasal congestion: blocked or runny nose.

Serious or Rare Side Effects: - Priapism: prolonged erection lasting more than four hours requiring 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 prescribing or dispensing Inventum Max, consider the following precautions to ensure safe use.

- Cardiovascular assessment: evaluate for recent myocardial infarction, unstable angina, or severe heart failure. - Nitrate use: avoid co‑administration with any nitrate medication due to risk of severe hypotension. - Liver and kidney function: adjust use in patients with moderate hepatic or renal impairment. - Timing of sexual activity: advise patients to take the tablet about one hour before intended activity and not exceed one dose per 24 hours. - Alpha‑blocker therapy: monitor blood pressure closely if used together, especially in the elderly. - Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Sildenafil citrate interacts with several drug classes; some combinations should be avoided while others require careful monitoring.

Major Interactions (Avoid): - Nitrates (e.g., nitroglycerin): can cause profound hypotension. - Guanylate cyclase stimulators (e.g., riociguat): additive vasodilatory effect leading to dangerous blood pressure drops. - Protease inhibitors (e.g., ritonavir): may markedly increase sildenafil plasma concentrations.

Moderate Interactions (Monitor Closely): - CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): may raise sildenafil levels, requiring dose adjustment. - CYP3A4 inducers (e.g., rifampin, carbamazepine): may reduce efficacy by lowering drug exposure.
