Malegra 100 is a medication used to treat erectile dysfunction (ED) in men. ED is a condition in which a man is unable to achieve or maintain an erection sufficient for sexual intercourse. Malegra 100 mg contains the active ingredient sildenafil citrate, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. PDE5 inhibitors work by increasing blood flow to the penis, which helps men achieve and maintain an erection.
  Tadacip 20 tablets work by relaxing the blood vessels in the penis and increasing blood flow to the penis. This medication also relaxes the muscles in the prostate and bladder, thereby improving the symptoms associated with an enlarged prostate.

How does it work?
PDE5 is a common cause of erectile dysfunction. PDE5 prevents cyclic guanosine monophosphate (CGMP), a neurochemical, from helping you get a satisfying erection, causing you to lose one. PDE5 disrupts the cGMP, which results in a lack of blood flow to the penis and the loss of erection.   Vidalista 40 is what you need in this situation.
Uses
For Erectile Dysfunction- Sildenafil Citrate, a PDE5 inhibitor, is present in  Cenforce 50. Sildenafil Citrate in   Cenforce 50   modulates the PDE5 enzyme in the penis, increasing blood flow through it.
Increased blood flow via the penis causes a strong erection. Sildenafil stimulates the flow of blood to the penis. This aids in the acquisition and maintenance of an erection.
Men with ED may benefit from using    Kamagra Oral Jelly. It is a substitute for Viagra and has the same active component, sildenafil citrate. With tastes like strawberry, banana, and pineapple, Kamagra Oral Jelly is more palatable for those who have trouble swallowing tablets.
For Pulmonary Arterial Hypertension  – Though    Cenforce 150 mg is an anti-erection medication, it is also used to treat Pulmonary Arterial Hypertension that occurs in the lungs. Sildenafil relaxes your muscles and dilates the blood vessels in your lungs. The blood pressure in your lungs is decreased as a result of this. Sildenafil benefits you by feeling better and slowing down the progression of your circumstance. It also improves your ability to work out.
