What is Viagra? The Science Explained
Viagra (generic: sildenafil citrate) is a prescription medication first introduced in 1998 as a revolutionary treatment for erectile dysfunction (ED). ED affects over 150 million men worldwide. Viagra’s impact extends far beyond sexual performance—restoring confidence, improving relationships, and offering hope to those struggling with medical issues that affect intimacy. It is also FDA-approved for pulmonary arterial hypertension under the brand name Revatio.

How Does Viagra Work? Mechanism of Action (MOA)
Viagra works by selectively inhibiting the enzyme phosphodiesterase type 5 (PDE5) in the smooth muscle of penile blood vessels. In the presence of sexual stimulation, Viagra allows blood vessels to dilate and stay open, increasing blood flow to the erectile tissue and leading to a firm, sustained erection.
- Step 1: Sexual arousal triggers nitric oxide release in penile tissue.
- Step 2: Nitric oxide activates cyclic guanosine monophosphate (cGMP), relaxing smooth muscle.
- Step 3: PDE5 breaks down cGMP, causing erection loss. Viagra blocks PDE5, preserving cGMP’s effect.
Indications: Who Should Use Viagra?
Viagra is indicated for:
- Men aged 18 and over with clinically diagnosed erectile dysfunction
- Those experiencing difficulty achieving or maintaining an erection
- Men with performance anxiety or physical conditions impacting sexual function
Consultation with a healthcare provider is mandatory to rule out underlying cardiac issues or medication contraindications.
Doctor and Pharmacist Comments: Real-World Experience
Dr. A. Martinez, Board-Certified Urologist: “Viagra revolutionized the treatment of ED. With proper evaluation, most men respond well to sildenafil, and side effects are typically mild and manageable.”
Maria Nguyen, PharmD: “It’s important to use Viagra as prescribed—never combine with nitrates or certain blood pressure medications. Stay within the recommended dose, and always talk to your pharmacist if you have questions about drug interactions or side effects.”
How to Use Viagra: Dosage, Timing, and Best Practices
- Starting Dose: Most men start with 50mg, taken about 1 hour before sexual activity.
- Adjustments: Dose can be increased to 100mg or lowered to 25mg depending on efficacy and tolerability.
- Maximum Frequency: Once per day only.
- With or Without Food? Best taken on an empty stomach for fastest effect. Fatty meals can delay absorption.
- Alcohol caution: Excessive drinking may reduce effectiveness or increase side effects.
| Viagra Dose | Recommended For | Key Considerations |
|---|---|---|
| 25mg | Elderly, renal/hepatic impairment | Lower side effect risk |
| 50mg | Most men | Standard starting dose |
| 100mg | For insufficient response | Do not exceed! |
