Kamagra ( https://www.medexpressrx.com/kamagra.aspx ) medication works on the main reason i.e. poor supply of blood to the male part. Its primary agent Sildenafil Citrate corrects this situation. This drug belongs to the PDE5 inhibitor group;hence, its main function is to suppress the activity of this natural enzyme. The decrease in this enzyme’s level causes the rise of two other chemicals i.e. NO and cGMP. These chemicals are responsible for the dilatation of the blood vessels and the relaxation of the penile muscles. This way the blood flow increases in the erectile region, which helps in initiating erection.
