Sildenafil is currently offered generically and, in some countries, even as an over-the-counter drug without a prescription, despite the fact that Pfizer's brand name Viagra has historically been the drug's most well-known name. By inhibiting the cGMP-specific phosphodiesterase type 5 (PDE5), sildenafil ultimately prevents or reduces the breakdown of cyclic guanosine monophosphate (cGMP). It's interesting to note that sildenafil was initially investigated as a possible treatment for angina, or chest pain brought on by insufficient blood flow to the heart, before being accidentally recommended for the treatment of erectile dysfunction in the late 1980s. Nevertheless, it is because of this mechanism that sildenafil is also prescribed to treat pulmonary arterial hypertension. However, it is also well known for interfering with other anti-anginal or anti-hypertensive medications, leading to the development of hypotensive crises that could be sudden, severe, and/or fatal. Nevertheless, sildenafil, among a number of other comparable or related PDE5 inhibitors, has emerged as a popular and efficient treatment for erectile dysfunction, and since it was officially approved for use in the public health in 1998, millions of prescriptions for it have been written globally. This results in increased blood flow into the spongy erectile tissue of the penis, allowing it to grow in size, become erect and rigid, and cGMP present in both the penis and pulmonary vasculature to elicit smooth muscle relaxation and vasodilation.
