1. Kamagra
Kamagra is a drug that helps men who suffer from erectile dysfunction (ED). ED is defined as the inability to achieve or maintain an erection firm enough for sexual intercourse. There are many causes of ED including diabetes, high blood pressure, depression, alcohol, smoking, obesity, and some medications. In addition to these factors, there are certain medical conditions that can cause ED. These include cardiovascular disease, neurological disorders, hormonal problems, and kidney failure.
2. Sildenafil Citrate
Sildenafil citrate is the active ingredient in Kamagra. It works by relaxing muscles in the penis and increasing blood flow to the penis. When combined with nitric oxide, sildenafil increases the amount of nitric oxide produced in the body. Nitric oxide relaxes smooth muscle cells in the arteries, veins, and penile chambers. By relaxing the smooth muscle cells, blood vessels become dilated and allow more blood to enter the penis. This results in increased blood flow to the penis and helps produce an erection.
3. Tadalafil
Tadalafil is the generic name for Cialis. It is a prescription medication that is taken orally. It was approved by the FDA in 2003 and is indicated for treatment of erectile dysfunction. It works by inhibiting PDE-5 enzyme. PDE-5 is responsible for breaking down cGMP in the corpus cavernosum. As a result, cGMP levels increase, which causes relaxation of smooth muscle cells in the corpora cavernosa. This results in increased arterial inflow and engorgement of the corporal sinusoids.
4. Vardenafil
Vardenafil is the generic version of Levitra. It is an oral medication used to treat erectile dysfunction. It is effective in treating both impotence and premature ejaculation. It works by blocking the action of phosphodiesterase type 5 (PDE-5) enzymes. This prevents breakdown of cyclic guanosine monophosphate (cGMP), which is necessary for normal penile function.
5. Avanafil
Avanafil is the generic form of Stendra. It is a prescription medicine that is used to treat erectile dysfunctions. It is a selective inhibitor of PDE-5 enzyme and is effective in treating erectile dysfunction. It does not have any negative side effects.
6. Viagra
Viagra is the brand name for sildenafil citrat. It is a prescription drug that is used to treat male erectile dysfunction. It increases blood flow to the penis by causing vasodilation. Vasodilation is the widening of the blood vessels. This results in improved blood flow to the penis, which leads to an erection.
7. Penegra
Penegra is the brand name for vardenafil. It is a prescription tablet that is used to treat impotence. It is a potent inhibitor of PDE-10 enzyme. PDE-10 breaks down cGMP in brain cells. As a result, the level of cGMP increases, which causes relaxation of the smooth muscle cells in the corpus cavernosums. This results in increased flow of blood into the penis.
