Chemical Name: Sildenafil

IUPAC Name: 5-[2-ethoxy-5-(4-methylpiperazin-1-yl)sulfonylphenyl]-1-methyl-3-propyl-1,6-dihydro-7H-pyrazolo[4,3-d]pyrimidin-7-one

Mechanism of Action: Sildenafil acts by inhibiting phosphodiesterase type 5 (PDE5), an enzyme responsible for the degradation of cGMP in the corpus cavernosum. When PDE5 is inhibited, levels of cGMP increase, leading to smooth muscle relaxation and enhanced blood flow to the penis, thereby aiding in the establishment of an erection.
