Introduction:
Sildenafil is a medication that is commonly used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). Sildenafil tablets 25 mg is one of the most popular dosages available for purchase online.

What are Sildenafil Tablets 25 mg?
Sildenafil tablets 25 mg are a type of ED medication that contains sildenafil citrate as the active ingredient. Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor, which means that it works by blocking the action of PDE5, a chemical that can cause ED by decreasing blood flow to the penis. By inhibiting PDE5, sildenafil helps to increase blood flow to the penis, making it easier for men to get and maintain an erection.
How do Sildenafil Tablets 25 mg Work?
Sildenafil tablets 25 mg work by increasing blood flow to the penis. When a man is sexually stimulated, nitric oxide is released into the penis, which activates an enzyme called guanylate cyclase. This enzyme increases levels of a chemical called cyclic guanosine monophosphate (cGMP), which relaxes the smooth muscle in the penis and increases blood flow. PDE5 is responsible for breaking down cGMP, which can cause ED by decreasing blood flow to the penis. By inhibiting PDE5, sildenafil helps to maintain high levels of cGMP and increase blood flow to the penis, making it easier for men to get and maintain an erection.
