Hydralazine/isosorbide dinitrate, sold under the brand name Bidil, is a fixed-dose combination medication used to treat self-identified Black people with congestive heart failure. It is a combination of hydralazine hydrochloride (an arteriolar vasodilator) and isosorbide dinitrate (a nitrate vasodilator).The American Food and Drug Administration (FDA) approved this race-specific medication to treat congestive heart failure in specifically self-identified Black patients. It provoked controversy as the first drug approved by the FDA marketed for a single racial-ethnic group. History
From 1980 to 1985, Dr. Jay Cohn of the University of Minnesota  led a clinical trial in collaboration with the US Veterans Administration called the Vasodilator-Heart Failure Trial (V-HeFT I) that tested whether the combination of isosorbide dinitrate and hydralazine increased survival in patients with heart failure. The results were promising and a follow up study, V-HeFT II, tested the novel combination against enalapril. Cohn applied for a patent on the combination treatment, which was issued in 1989 as US Patent 4868179. Cohn then licensed the patent to Medco Pharmaceuticals who went on to prepare a New Drug Application (NDA) to approve BiDil on the basis of the V-HeFT trials.The V-HeFT data was re-analyzed and found that the drug combination appeared to be more effective in treating self-identified African-Americans. This was a significant finding due to prior studies which showed that African-Americans with congestive heart failure (CHF) appeared to respond less effectively to conventional CHF treatments (particularly ACE inhibitors) than White Americans.
A ectopic testis is a testicle that, although not an undescended testicle, has taken a non-standard path through the body and ended up in an unusual location.The positions of the ectopic testis may be: in the lower part of the abdomen, front of thigh, femoral canal, skin of penis or behind the scrotum. The testis is usually developed, and accompanied by an indirect inguinal hernia. It may be divorced from the epididymis which may lie in the scrotum. See also
