Discovery of Vardenafil Citrate:
In the year 2003, two significant PDE5 inhibitors were discovered, which were known as Vardenafil and tadalafil. Both drugs were approved by the FDA for different medical purposes. This drug was co-marketed by different companies such as Schering-Plough, GlaxoSmithKline, and Bayer Pharmaceuticals. The most significant indication of these two drugs was the treatment of male erectile dysfunction.
Mechanism of action of Vardenafil Citrate:
Vardenafil Citrate is the selective PDE5 (phosphodiesterase type-5) inhibitor, which is used as a significant therapy for erectile dysfunction. Vardenafil Citrate is also a benzene sulfonamide derivative, which inhibits the PDE5 along with the vasodilator properties.
Vardenafil Citrate selectively inhibits the PDE5, as a result, it inhibits the cGMP (cyclic guanosine monophosphate) degradation, which is found in the smooth muscles of corpus spongiosum and corpus cavernosa in the penis. The cGMP degradation inhibition results in the prolonged vasodilation and relaxation of the penile muscles. As a result of vasodilation, blood engagement and blood flow to the penis increase, which in turn increases the erection of the penis.
Clinical applications of Vardenafil Citrate:
Sexual dysfunction:
Vardenafil and several other PDE5 inhibitors work for the treatment of erectile dysfunction by allowing a better flow of blood to the penis. For understanding the action of Vardenafil Citrate for sexual dysfunction, you need to understand the process of erection which is:
- When a man becomes sexually aroused, the brain tends to send a signal to the blood vessels present in the penile area to stimulate the release of a chemical known as nitric oxide. This nitric oxide diffuses inside the vasculature of the penis to stimulate the formation of another molecule known as cGMP. The cGMP helps in relaxing the blood vessels of the penis to allow even more flow of blood inside.
In some men, it is difficult to achieve an erection even when they are sexually aroused. In such cases, the cGMP is broken down by the PDE5 enzyme to not achieve the relaxation of penile smooth muscles. Vardenafil Citrate inhibits the PDE5 enzyme, which causes the breakdown of cGMP. Inhibition of this enzyme results in increasing the amount of cGMP present in the blood vessels and also facilitates the entry of the blood inside.
Along with treating erectile dysfunction, some PDE5 inhibitors are also in use for the treatment of a medical condition such as pulmonary hypertension.
