The Kamagra Effervescent pill contains a potent PD5 inhibitor drug that works to remove contractions in the arteries and improves blood flow to the penile organ. The working of PDE5 inhibitors is slightly complex. This drug temporarily works to inhibit the enzyme that blocks the blood flow to the penile organ. It helps to stop the degradation of the cyclic Guanosine Monophosphate (cGMP). Nitric oxide is also responsible for boosting enough blood to the male reproductive organ, encouraging a strong and durable erection. However, sexual stimulation is essential for this drug to work.
