VIAGRA (Sildenafil Citrate) – Erectile Dysfunction Treatment

Overview:
VIAGRA (Sildenafil Citrate) is a prescription medication used to treat erectile dysfunction (ED) in men. It works by improving blood flow to the penis during sexual arousal, helping men achieve and maintain an erection. Sildenafil, the active ingredient in VIAGRA, is a phosphodiesterase type 5 (PDE5) inhibitor that enhances the natural erectile response. VIAGRA is also used in some cases to treat pulmonary arterial hypertension (PAH).

Key Benefits:

• Effective ED Treatment: Improves ability to achieve and maintain an erection during sexual stimulation.

• Supports Urination: May improve urinary flow by relaxing smooth muscles in the prostate.

• Enhanced Confidence & Quality of Life: Improves self-esteem and sexual satisfaction.

• Heart & Circulation Support: PDE5 inhibition enhances blood flow safely under medical supervision.

• Daily Low-Dose Option: May reduce progression of ED when taken daily at low doses.

How VIAGRA Works:
VIAGRA enhances the effect of nitric oxide (NO) released during sexual stimulation. NO activates guanylate cyclase, increasing cyclic guanosine monophosphate (cGMP) levels. Elevated cGMP relaxes smooth muscle in the corpus cavernosum, allowing increased blood flow to the penis, resulting in an erection. Sildenafil’s action depends on sexual stimulation and has no effect without it.

Key Ingredients:

• Sildenafil Citrate: 25 mg, 50 mg, or 100 mg per tablet.

• Chemical Structure: C22H30N6O4S, contains a pyrazolopyrimidine core, ethoxy, and sulfonyl-methylpiperazine groups.

Recommended Dosage:

• Typical starting dose: 50 mg, taken 30 minutes to 4 hours before sexual activity.

• Maximum dose: 100 mg per day.

• Special considerations: Lower doses (25 mg) for patients on nitrates, CYP3A4 inhibitors, alpha-blockers, or with hepatic/renal impairment.

Usage Instructions:

• Take on an empty stomach or with a light meal; avoid high-fat meals.

• Limit alcohol consumption to reduce side effects like dizziness or low blood pressure.

• Avoid grapefruit and grapefruit juice as they can increase sildenafil levels.

• Do not take with nitrate medications or certain chest pain drugs.

Warnings & Precautions:

• May not be suitable for men with certain cardiovascular conditions.

• Possible side effects: headaches, flushing, indigestion, vision changes, dizziness. Rarely, sudden vision or hearing loss may occur—seek medical attention immediately.

• Priapism: Seek urgent care if an erection lasts >4 hours.
