Manforce (Sildenafil Citrate)

Introduction

Manforce is a tablet formulation that contains 100 mg of sildenafil citrate, the active ingredient widely used to treat erectile dysfunction (ED) in adult males. Sildenafil citrate belongs to the phosphodiesterase-type 5 (PDE-5) inhibitor class. The medication is approved by major regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the management of ED and, in lower dosages, for pulmonary arterial hypertension (PAH). In addition to its primary indication, clinicians occasionally employ sildenafil off-label for conditions such as benign prostatic hyperplasia-related lower urinary tract symptoms and certain forms of Raynaud’s phenomenon, although these uses remain investigational and are not formally sanctioned by regulatory bodies.

What is Manforce?

Manforce is a generic tablet that delivers 100 mg of sildenafil citrate. It is classified as a PDE-5 inhibitor and was originally developed in the early s for cardiovascular research before its utility in erectile dysfunction was discovered. While the brand name “Viagra” and “Revatio” are among the most recognized marketed products containing sildenafil citrate, Manforce provides a cost-effective alternative without compromising therapeutic potency. Our online pharmacy supplies this generic version as a reliable, affordable treatment option for patients seeking ED relief or PAH management.

How Manforce Works

Sildenafil citrate selectively inhibits the enzyme phosphodiesterase-type 5. In the penile tissue, sexual stimulation releases nitric oxide, which activates guanylate cyclase and increases cyclic guanosine monophosphate (cG MP). Elevated cG MP relaxes smooth muscle and allows blood to fill the corpora cavernosa, producing an erection. By blocking PDE-5, sildenafil prevents the breakdown of cG MP, thereby prolonging smooth-muscle relaxation and enhancing erectile response.

After oral ingestion, peak plasma concentrations are reached in approximately 30-120 minutes. The drug’s half-life ranges from 3 to 5 hours, allowing a therapeutic window that supports spontaneous sexual activity throughout the day. Sildenafil is metabolized primarily by hepatic cytochrome P450 enzymes (CYP3A4 and CYP2C9) and excreted in urine and feces.

Conditions Treated with Manforce

• Erectile Dysfunction (ED): Sildenafil restores the physiological cascade required for erection, improving sexual performance in men with vascular or neurogenic causes of ED. Clinical trials have demonstrated efficacy in over 70 % of treated participants.
• Pulmonary Arterial Hypertension (PAH): At lower doses (typically 20 mg three times daily), sildenafil induces vasodilation in the pulmonary vasculature, reducing pulmonary arterial pressure and improving exercise capacity. The FDA approved this indication based on the SUPER study, which showed significant improvements in the six-minute walk distance.

These approved uses are supported by robust randomized, controlled trials and are reflected in the product labeling of regulatory agencies.

Off-Label and Investigational Uses of Manforce

• Benign Prostatic Hyperplasia (BPH)-related Lower Urinary Tract Symptoms: Small pilot studies have reported that sildenafil may relax prostatic smooth muscle, alleviating urinary frequency and nocturia. Evidence remains limited, and formal approval has not been granted.
• Raynaud’s Phenomenon: Some clinicians have used sildenafil to improve digital blood flow in severe cases. Randomized trials suggest modest benefit, but safety data are insufficient for routine recommendation.

These applications are not approved by the FDA or EMA. Patients considering off-label use should consult a qualified healthcare provider to evaluate potential benefits, risks, and drug interactions.

Is Manforce the Right Medication for You?

Manforce is appropriate for adult males diagnosed with erectile dysfunction of physiological origin and for individuals with documented pulmonary arterial hypertension. It is particularly useful when a fast-acting oral agent is desired, as the 100 mg tablet provides a convenient dosing regimen with predictable onset.

Contraindications include:

• Concomitant use of nitrates (e.g., nitroglycerin) due to risk of severe hypotension.
• Severe uncontrolled hypertension or recent myocardial infarction.
• Known hypersensitivity to sildenafil or any tablet components.

Patients with severe hepatic impairment, retinal disorders such as retinitis pigmentosa, or a history of priapism should discuss alternative therapies with a clinician.

Risks, Side Effects, and Interactions

Common

• Headache
• Flushing
• Indigestion or dyspepsia
• Nasal congestion

These events are typically mild, transient, and resolve without medical intervention.

Rare

• Visual disturbances (e.g., blue-tinted vision, blurred vision)
• Hearing loss or tinnitus
• Myalgia or back pain

Patients experiencing these symptoms should evaluate the need for continued therapy.

Serious

• Priapism (prolonged erection lasting > 4 hours) - requires immediate medical attention to prevent permanent tissue damage.
• Severe hypotension - especially when combined with nitrates or potent vasodilators.
• Cardiovascular events (e.g., myocardial infarction, stroke) in high-risk individuals.

Any occurrence of serious adverse effects warrants urgent evaluation by a qualified professional.

Drug-Drug Interactions

• Nitrates (isosorbide dinitrate, nitroglycerin): additive vasodilatory effect → risk of life-threatening hypotension.
• Alpha-blockers (tamsulosin, prazosin): may cause marked blood pressure reduction.
• Strong CYP3A4 inhibitors (ketoconazole, ritonavir): increase sildenafil plasma levels → heightened side-effect risk.
• CYP3A4 inducers (rifampin, carbamazepine): may reduce efficacy.

Drug-Food Interactions

• High-fat meals can delay absorption, extending the onset of effect by up to 60 minutes.
• Moderate alcohol intake generally does not affect efficacy, but excessive consumption may increase the likelihood of hypotension and dizziness.

Use: Dosing, Missed Dose, Overdose

Standard Dosing - For erectile dysfunction, the recommended starting dose is 50 mg taken as needed about one hour before sexual activity. The dose may be adjusted to 25 mg or 100 mg based on efficacy and tolerability. Do not exceed one tablet within a 24-hour period.

Pulmonary Arterial Hypertension - The approved regimen is 20 mg three times daily, taken with or without food.

Missed Dose - If a dose is forgotten and the scheduled time is still several hours away, take the tablet at the next planned time. Do not double the dose to compensate for a missed one.

Overdose - Symptoms of overdose may include profound hypotension, prolonged erection, and severe headache. Seek immediate medical attention if these occur. No specific antidote exists; management is supportive and may involve intravenous fluids and vasopressors under professional supervision.

Practical Precautions -

• Avoid taking Manforce with grapefruit juice, as it can inhibit CYP3A4 metabolism.
• Do not operate heavy machinery or drive if dizziness or visual changes occur.
• Store tablets at controlled room temperature, protected from moisture and light.
