Sitaxsentan in Proteinuric Chronic Kidney Disease
brief summary
Patients with chronic kidney disease (CKD) have higher blood pressures than the general population. They also tend to have protein leaking into the urine (proteinuria). CKD, high blood pressure and proteinuria independently and together increase the risk of developing atherosclerosis (hardening) of the arteries that leads to diseases such as heart attack and stroke. Although there are a number of drugs available that lower blood pressure, these are not always fully effective. Furthermore, there are even fewer drugs that simultaneously lower blood pressure, reduce proteinuria, and slow down kidney damage in CKD. Recent research has shown that drugs like sitaxsentan not only lower blood pressure but also reduce proteinuria and potentially slow down the progression of CKD \[1,2\]. Before sitaxsentan can become freely available to individuals with CKD it is important to look at the effects this drug could have on proteinuria and blood pressure. 1.
