Fildena 100, containing sildenafil citrate as its active ingredient, typically takes about 30 to 60 minutes to start showing its effects after ingestion. However, the onset of action can vary depending on factors such as individual metabolism, the presence of food in the stomach, and overall health condition.
Upon ingestion, Fildena 120 citrate gets absorbed into the bloodstream and starts inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for the degradation of cyclic guanosine monophosphate (cGMP). This inhibition leads to an accumulation of cGMP, causing smooth muscle relaxation and vasodilation in the corpus cavernosum of the penis, ultimately facilitating increased blood flow to the erectile tissue and thereby inducing an erection.
