They belong to a class of drugs called phosphodiesterase 5 inhibitors (PDE5 inhibitors), which will be explained below.

An erection might last indefinitely if it weren’t for chemicals called phosphodiesterases. They work at reversing the process that keeps the penis erect.

    The Food and Drug Administration has approved a pill that aims to increase a woman’s desire for sex — a controversial decision made only after an extended lobbying campaign by the drug’s makers. But the agency’s imposed an unusual number of restrictions on who can prescribe the drug and how they can prescribe it — moves aimed at minimizing concerns over its side effects. The pill’s called flibanserin and will be marketed under the brand name Addyi. The FDA is asking its maker, Sprout Pharmaceuticals, to specially train doctors and pharmacists who dispense it and to keep track of any problems with women taking the drug. Only trained physicians will be allowed to write prescriptions for the pill. The FDA is also requiring a strong warning to women that they should never drink alcohol while taking the drug and stressing the risk that it can cause sudden fainting – a special danger for drivers. Sprout, which bought rights to the drug when pharma giant Boehringer Ingelheim dumped it, helped wage a public relations campaign called "Even the Score." It claimed that while men have many different sexual dysfunction drugs to choose from, including Viagra and Cialis, women have none."Today's approval provides women distressed by their low sexual desire with an approved treatment option," said Dr. Janet Woodcock, director of the FDA's Center for Drug Evaluation and Research.
