1. Description

Cenforce 100 mg is a branded oral tablet whose active ingredient is sildenafil (sildenafil citrate), at a dose equivalent to 100 mg sildenafil per tablet. Sildenafil is indicated primarily for the treatment of erectile dysfunction (ED) in adult men by facilitating achievement and maintenance of erection sufficient for sexual activity. It is a prescription medication; use should be guided by a physician after assessment of cardiovascular status and other comorbidities.

Clinical summary

• Formulation: oral tablet, 100 mg sildenafil.
• Onset: usually within 30–60 minutes (can be earlier in some individuals).
• Duration: clinically useful effects typically last up to 4 hours; residual activity may persist longer in some patients.
• Pharmacokinetics: rapidly absorbed; bioavailability reduced by high-fat meals; half-life ≈ 3–5 hours. Metabolized primarily by hepatic CYP3A4 (and CYP2C9).

2. How does Cenforce 100mg work?

Sildenafil is a selective inhibitor of the enzyme phosphodiesterase type 5 (PDE5). During sexual stimulation, nitric oxide (NO) is released in the corpus cavernosum, which increases cyclic guanosine monophosphate (cGMP). cGMP causes smooth muscle relaxation in penile blood vessels and increased blood inflow producing an erection. PDE5 normally degrades cGMP; inhibition of PDE5 by sildenafil increases cGMP levels, enhancing and prolonging smooth muscle relaxation and blood flow to the penis, thereby facilitating erection in the presence of sexual stimulation.

Important pharmacologic notes:

• Sildenafil does not cause sexual stimulation or libido increase by itself; sexual arousal is required.
• It has systemic vasodilatory effects; therefore it can lower blood pressure and interact with other vasoactive medications.

3. Dosage

General principles

• The recommended dosing range for sildenafil for ED is 25–100 mg taken orally as needed, approximately 30–60 minutes before sexual activity. Cenforce 100 mg contains 100 mg; this is the maximum recommended single dose for typical adult use.
• Maximum frequency: once per 24 hours.
• If no effect or inadequate effect, dosing adjustments and evaluation by a clinician are advised rather than simply increasing frequency.

Usual dosing guidance

• Typical starting dose (for many patients): 50 mg 30–60 minutes before sexual activity, titrate to 25 mg or 100 mg based on efficacy and tolerability.
• If the prescriber has already selected Cenforce 100 mg as the dose, take one 100 mg tablet roughly 30–60 minutes prior to anticipated sexual activity.
• Do not exceed 100 mg in a 24-hour period.

Special populations and dose adjustments

• Elderly (≥65 years): start with lower dose (25–50 mg) because of increased plasma concentrations and greater susceptibility to adverse events; if used, monitor response and tolerability. If a prescriber selects 100 mg they should justify the choice and monitor carefully.
• Renal impairment: moderate to severe renal impairment (creatinine clearance <30 mL/min) → start with 25 mg and titrate carefully; avoid routine use of 100 mg without specialist input.
• Hepatic impairment: moderate to severe hepatic impairment increases sildenafil exposure; start at 25 mg in most cases and adjust carefully; severe impairment may contraindicate use or require specialist oversight.
• Concomitant strong CYP3A4 inhibitors (e.g., ritonavir, certain azole antifungals, some macrolide antibiotics): these significantly increase sildenafil levels — recommended dose reduction (often to 25 mg) and increased dosing interval (some agents require 25 mg once every 48 hours; follow specific interaction guidance). Do not self-adjust — consult prescriber/pharmacist.
• Concomitant CYP3A4 inducers (e.g., rifampicin, carbamazepine) may reduce sildenafil levels and efficacy — dose adjustments may be required under medical supervision.

Concomitant medications

• Nitrates (e.g., nitroglycerin, isosorbide dinitrate): concomitant use is contraindicated due to risk of severe hypotension.
• Riociguat: co-administration is contraindicated.
• Alpha-blockers (for benign prostatic hyperplasia or hypertension): use with caution; start with low doses and monitor blood pressure; symptomatic hypotension can occur.
• Antihypertensives: additive hypotensive effects possible; monitor blood pressure.

Administration tips

• Take on an empty stomach for faster onset; high‑fat meals can delay absorption and onset of effect.
• Avoid excessive alcohol; alcohol can impair erectile function and increase risk of hypotension and dizziness.
• Do not crush or chew tablets unless instructed; swallow with water.

When to seek physician review or emergency care

• If erection lasts >4 hours (priapism) — seek immediate medical attention to avoid permanent injury.
• If sudden loss of vision or hearing occurs, stop the drug and seek immediate medical care.
• If chest pain, severe dizziness, fainting, or other cardiac symptoms occur — seek emergency care.

4. Side effects

Common (generally mild to moderate)

• Headache
• Flushing
• Dyspepsia (indigestion)
• Nasal congestion
• Dizziness
• Visual disturbances (e.g., blurred vision, altered color perception, blue tint)
• Myalgia/back pain (usually transient)

Less common / serious (require prompt attention)

• Priapism: prolonged painful erection (>4 hours) — medical emergency.
• Sudden decrease or loss of vision in one or both eyes (rare, possible nonarteritic anterior ischemic optic neuropathy, NAION).
• Sudden decrease or loss of hearing, sometimes with tinnitus and dizziness.
• Severe hypotension: fainting or syncope, especially when combined with nitrates or alpha-blockers.
• Cardiovascular events: chest pain, myocardial infarction, arrhythmias, especially in patients with preexisting cardiovascular disease or those engaging in sexual activity that imposes physical exertion. While causal relationship is not established for all events, caution is warranted.
• Allergic reactions: rash, pruritus, angioedema; seek care for signs of anaphylaxis.

Precautions and contraindications (summary)

• Contraindicated with concurrent nitrates or riociguat.
• Use caution in patients with significant cardiac disease (unstable angina, recent MI or stroke, severe heart failure).
• Caution in conditions predisposing to priapism (sickle cell disease, multiple myeloma, leukemia) and penile anatomical deformities (Peyronie’s disease).
• Known hypersensitivity to sildenafil or any excipient is a contraindication.

Drug interactions (high-priority)

• Nitrates: absolute contraindication.
• Strong CYP3A4 inhibitors (ritonavir, saquinavir, ketoconazole, itraconazole): increase sildenafil exposure — dose adjustments required.
• CYP3A4 inducers can decrease effectiveness.
• Alpha‑blockers: increased risk of symptomatic hypotension — titrate and monitor.
• Other antihypertensives: additive blood-pressure lowering effect.

Always inform the prescriber about all medications (prescription, OTC, and herbal), cardiovascular history, and other medical conditions prior to use.

5. Storage

• Store at room temperature, typically 20–25 °C (68–77 °F). Short excursions allowed as per local labeling (commonly 15–30 °C).
• Keep in original packaging to protect from moisture and light.
• Protect from excessive heat and humidity (do not store in bathroom).
• Keep out of reach and sight of children and pets.
• Do not use after the expiration date printed on the packaging.
• Dispose of unused or expired tablets according to local regulations; do not flush medications down the toilet unless instructed.
