The Viagra drug is a medication that has been approved by the FDA for the treatment of ED and ED problems.
It belongs to a group of drugs called phosphodiesterase type 5 (PDE5) inhibitors.
PDE5 inhibitors work by relaxing the blood vessels in the penis, allowing the flow of blood to the penis. This helps you get and maintain an erection.
PDE5 inhibitors also block PDE5, which means that when nitric oxide is released, it triggers a reaction in the body called cyclic guanosine monophosphate (cGMP). cGMP relaxes the smooth muscles in the blood vessels, allowing more blood to reach the penis.
When cGMP is released, nitric oxide is added to the blood vessels in the penis, causing an erection. The increased blood flow allows more blood to be pumped to the penis. When this happens, nitric oxide relaxes the smooth muscles in the penis, causing an erection.
The drugs Viagra and Cialis have been approved for the treatment of ED and ED problems.
Viagra is available as a generic drug and is also available as the brand-name medication, Cialis.
The usual dosage of Viagra for treating ED is 5 milligrams (mg). That’s a low dosage.
