Description
Hiforce (Sildenafil) 200 mg
Hiforce 200 mg is identified as a sildenafil product. Sildenafil is a prescription phosphodiesterase-5 (PDE5) inhibitor used for erectile dysfunction. Product names and strengths can vary by market, so the active ingredient is the key verified identifier.
Active Ingredient and Medicine Class
The verified active ingredient is sildenafil, a PDE5 inhibitor. This medicine class helps increase blood flow in the penis during sexual stimulation by enhancing the nitric oxide–cGMP pathway.
Established Medical Uses
Sildenafil is established for the treatment of erectile dysfunction in adult men. Official prescribing information for sildenafil tablets also describes other sildenafil products for pulmonary arterial hypertension, but that is a different indication and formulation.
How It Works
Sildenafil inhibits PDE5, an enzyme that breaks down cyclic GMP. By reducing PDE5 activity, it supports smooth muscle relaxation and blood flow in penile tissue when sexual stimulation is present.
Important Safety Information
Sildenafil is contraindicated with organic nitrates and with riociguat because of the risk of dangerous hypotension. It should also not be used in people with known hypersensitivity to sildenafil or any tablet component. Caution is advised in patients with cardiovascular disease, low blood pressure, recent major cardiovascular events, significant liver or kidney impairment, anatomical penile deformity, or conditions that may predispose to priapism. Important interactions include alpha-blockers and strong CYP3A4 inhibitors such as ritonavir and ketoconazole, which can increase blood-pressure effects or sildenafil exposure.
Possible Side Effects
Common adverse effects include headache, flushing, dyspepsia, nasal congestion, abnormal vision, dizziness, and rash. Serious reactions reported with sildenafil include prolonged erection or priapism, sudden vision loss, sudden hearing decrease or loss, and hypersensitivity reactions.
Scientific Evidence
Systematic review evidence shows sildenafil is more effective than placebo for improving erectile function and successful intercourse attempts in men with erectile dysfunction. Review literature also supports its general tolerability, while confirming that adverse effects and contraindications are clinically important.
