Levitra (Vardenafil) Buyer and Patient Handbook in South Africa

What is Levitra?

Levitra is a tablet that contains the active ingredient vardenafil, belonging to the phosphodiesterase-5 (PDE5) inhibitor class used to treat Erectile Dysfunction (ED). It is approved by the South African Health Products Regulatory Authority (SAHPRA) and is available in strengths of 10 mg, 20 mg, 40 mg and 60 mg.

Who Should Use Levitra?

• Men aged 18 years and older who experience difficulty achieving or maintaining an erection suitable for sexual activity.
• Individuals whose ED is related to Diabetes, hypertension, prostate surgery or psychological factors.
• Patients who have tried other PDE5 inhibitors without satisfactory results (under medical guidance).

How Does It Work?

Levitra works by blocking the enzyme PDE5, which normally breaks down cyclic guanosine monophosphate (cGMP). By preserving cGMP, blood vessels in the penis relax, allowing increased blood during sexual stimulation. Think of it as removing a roadblock that prevents traffic (blood) from reaching the destination (erectile tissue).
