Fildena CT 100 contains sildenafil citrate, a PDE5 inhibitor used to treat erectile dysfunction (ED) in adult men. The “CT” form means it is a chewable tablet, which can be taken without water and may dissolve faster than standard tablets. A typical treatment journey with Fildena CT 100 mg starts when a doctor prescribes it after evaluating erectile dysfunction severity, medical history, and cardiovascular risk. The medication works by increasing blood flow to the penis during sexual stimulation through inhibition of phosphodiesterase type 5 (PDE5), leading to higher levels of cyclic guanosine monophosphate (cGMP) and relaxation of smooth muscles in the corpus cavernosum.
