Selexipag, sold under the brand name Uptravi, is a medication used to treat pulmonary arterial hypertension (PAH).[2] Generally it is used in people in who an endothelin receptor antagonist and PDE5 inhibitor are not enough.[4] It is taken by mouth or injection into a vein.[2]

Common side effects include headache, diarrhea, muscle pain, flushing, and rash.[3] Other side effects can include pulmonary edema.[3] It should not be used in people with significant coronary artery disease or valvular heart disease.[1] It works by activating the prostacyclin receptor which causes the muscles in blood vessels to relax.[1]

Selexipag was approved for medical use in the United States in 2015 and Europe in 2016.[3][1] In the United States it costs about 20,100 USD a month as of 2021.[5] In the United Kingdom this amount costs the NHS about £3,000.[4]

Medical use

It is used for pulmonary arterial hypertension (AH), which involves abnormally high blood pressure in the arteries of the lungs.[1]

Dosage

It is started at a dose of 200 mcg twice per day, which is than increased up to 1,600 mcg twice per day.[2]

Contraindications

In Europe, use of selexipag together with strong inhibitors of the liver enzyme CYP2C8, such as gemfibrozil, is contraindicated because it increases concentrations of selexipag twofold, and its active metabolite 11-fold, potentially leading to more adverse effects.[6]

Side effects

The adverse effects of selexipag are similar to those of intravenous prostacyclins used for pulmonary arterial hypertension. Common side effects include headache and jaw pain. An increased risk for hyperthyroidism has also been noted in people taking selexipag.

Mechanism of action

Selexipag mechanism of action (and key pathways targeted in treatment of pulmonary arterial hypertension by other medication)[7]

Selexipag and its active metabolite, ACT-333679 (or MRE-269, the free carboxylic acid), are agonists of the prostacyclin receptor, which leads to vasodilation in the pulmonary circulation.[8]

History

The U.S. Food and Drug Administration (FDA) granted selexipag orphan drug status for PAH.[9] It was approved by the FDA on 22 December 2015.[9]

In Europe, the drug was approved in May 2016.[10]

Society and culture

Cost

The price for the drug in the US in 2016 was $160,000 to $170,000 per person before rebates.[11]
