Description
Viagra (60 x 50mg), with the active compound sildenafil citrate, is a selective phosphodiesterase type 5 (PDE5) inhibitor originally developed for cardiovascular applications before becoming the first FDA-approved oral therapy for erectile dysfunction. Its mechanism involves:
• Potentiation of nitric oxide (NO)-mediated vasodilation
• Inhibition of cGMP degradation in smooth muscle tissue
• Enhanced blood flow to genital vascular networks
Clinical pharmacology studies demonstrate:
Onset of action within 30-60 minutes
Duration of effect lasting approximately 4 hours
Peak plasma concentrations at 30-120 minutes post-dose
Research continues to explore:
Vascular applications beyond erectile dysfunction
Potential pulmonary hypertension benefits
Effects on endothelial function
Gender-specific vascular responses
Note: The compound requires sexual stimulation for therapeutic effect and is contraindicated with nitrate medications. Ongoing research investigates its pharmacokinetic profile and potential applications in vascular medicine. Available product may not match displayed product image.
