What does Kamagra do? Effects, Risks & Legal Alternatives

What does Kamagra do?

Kamagra works by blocking the PDE-5 enzyme, causing more blood to flow to your penis during sexual arousal . However, this erectile dysfunction medication contains the same active ingredient as Viagra (sildenafil citrate) and is completely illegal in the Netherlands , posing significant health risks.

What does Kamagra do: The mechanism of action explained

How Kamagra Works in Your Body

Kamagra contains sildenafil citrate , a molecule that fits perfectly onto the PDE-5 enzyme in your penis, lungs, and blood vessels. When you become sexually aroused, a complex chemical reaction occurs:

Step 1 : Your nervous system produces nitric oxide (NO) in your penis.

Step 2 : This NO activates the enzyme guanylate cyclase.

Step 3 : This enzyme produces cyclic GMP (cGMP).

Step 4 : The cGMP causes the blood vessels in your penis to relax.

Step 5 : More blood flows to the erectile tissues. You get an erection.

Step 6 : Normally, the PDE-5 enzyme breaks down the cGMP again.

Kamagra blocks step 6. The PDE-5 enzyme can no longer break down cGMP. As a result, more cGMP remains active, resulting in a firmer and longer erection.

Important : Kamagra only works with sexual arousal. The medication does not automatically cause an erection.

Timeline of effectiveness

The way Kamagra works follows a predictable pattern:

• 30-60 minutes: The effect begins
• 60-120 minutes: The peak effect occurs
• 4-6 hours: Total operating time

Food affects the effect . A high-fat meal significantly slows down absorption.

Illegal use in figures

The use of Kamagra in the Netherlands is enormous. Wastewater research from 2025 shows shocking figures:

Why Kamagra is Completely Illegal

• Phase ISafety in 20-100 healthy volunteers
• Phase II: Effectiveness in 100-300 patients
• Phase IIILarge studies with 1000-3000 patients
• Stage IVPost-market monitoring

Kamagra has not gone through any of these phases . There are no independent studies on quality or safety.

Side effects and health risks

Scientific studies with more than 10.000 men show:

Serious risks

Life-threatening side effects occur in less than 1%:

Sudden vision loss (0,005-0,01%): Due to damage to the optic nerve.

Sudden hearing loss (0,01-0,05%): Can be permanent.

Heart problems : Sildenafil lowers blood pressure by an average of 8-10 mmHg. In heart patients, this can cause a heart attack.
