Fildena 100 contains sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. When taken orally, the tablet is absorbed in the digestive system and then enters the bloodstream, where it exerts its effects.

Here's a general overview of how sildenafil citrate is absorbed in the digestive system:

1. Oral Administration: Fildena 100 is usually taken orally with a glass of water. The tablet is designed to be swallowed whole.

2. Absorption: After ingestion, the tablet travels down the esophagus and reaches the stomach. In the stomach, the tablet begins to disintegrate, and the active ingredient, sildenafil citrate, is released.

3. Small Intestine: The majority of drug absorption occurs in the small intestine. Sildenafil citrate is absorbed into the bloodstream through the lining of the small intestine.

4. Bloodstream: Once in the bloodstream, sildenafil citrate is carried to various tissues, including the erectile tissue of the *****.

5. Mechanism of Action: Sildenafil citrate works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), leading to an increase in the levels of cyclic guanosine monophosphate (cGMP). This, in turn, relaxes the smooth muscles of the blood vessels in the *****, allowing for increased blood flow.

It's important to note that individual responses to medication can vary. Factors such as the presence of food in the stomach, individual metabolism, and other medications being taken can influence the absorption and effectiveness of Fildena 100. Always follow the prescribed dosage and instructions provided by your healthcare professional. If you have specific concerns or questions about the absorption of Fildena 100, it's best to consult with your healthcare provider.
