ReviewRecent Perioperative Pharmacological Prevention of Acute Kidney Injury after Cardiac Surgery: A Narrative Review.
Acute kidney injury (AKI) is a common and severe complication of cardiac surgery, and related rates of both hospitalization and long-term mortality are increasing. A number of studies have explored the preventive effects of perioperative pharmacological therapy on AKI after cardiac surgery. However, the mechanisms of AKI are multifaceted, and no universal treatment has been confirmed as beneficial. We review and analyze several current perioperative pharmacological therapies for AKI after cardiac surgery to identify promising preventive strategies.

Selexipag (Uptravi®) is an orally active, first-in-class, selective prostacyclin IP receptor agonist. Selexipag was approved recently in the EU for the long-term treatment of pulmonary arterial hypertension (PAH) in adult patients with WHO functional class (FC) II or III as combination therapy in patients insufficiently controlled with an endothelin receptor antagonist and/or a phosphodiesterase type 5 inhibitor or as monotherapy in patients who are not candidates for these therapies, and in the USA for the treatment of PAH (WHO Group I) to delay disease progression and reduce the risk of hospitalization for PAH. Selexipag (200-1600 μg twice daily, as tolerated) significantly reduced the risk of the primary composite endpoint of all-cause death or a complication related to PAH (whichever happened first) versus placebo in patients with PAH (mainly WHO FC II or III) in the large, randomized, placebo-controlled GRIPHON study. ⋯ Exercise capacity was also improved with selexipag versus placebo. Selexipag was generally well tolerated, with an adverse event profile consistent with other therapies targeting the prostacyclin pathway. Thus, selexipag extends the treatment options available in patients with PAH.
