People with pulmonary arterial hypertension (PAH) may be able to improve their ability to exercise by taking Adcirca. This prescription medication works by relaxing the blood vessels in the lungs, which helps to improve blood flow. The drug is available in tablet form, and is taken only once a day. Potential side effects include headaches, nausea, and heartburn.
What Is Adcirca?
How Does Adcirca Work?Adcirca belongs to a class of drugs called phosphodiesterase type-5 (PDE5) inhibitors. PDE5 is an enzyme responsible for breaking down a chemical found in the blood vessels of the lungs that causes them to relax.
By blocking PDE5, Adcirca allows more of this chemical to be available. As a result, the blood vessels in the lungs stay relaxed, allowing blood to flow more easily through them.
Clinical Effects of AdcircaClinical studies have shown that Adcirca can improve the ability to exercise in people with pulmonary arterial hypertension. In one study, people taking Adcirca for 16 weeks were able to walk 33 meters farther, on average, than people taking a placebo (a "sugar pill" that does not contain any active ingredients). People taking Adcirca also had fewer complications from their pulmonary arterial hypertension.
