How a Brazilian snake's venom led to a widely used blood pressure drug

The Brazilian pit viper, Bothrops jararaca, has been a focal point in research leading to significant medical breakthroughs. In the 1960s, Sergio Ferreira uncovered a peptide from this snake that plays a crucial role in blood pressure regulation. This groundbreaking discovery eventually paved the way for captopril, the pioneering ACE inhibitor approved in 1981, which has transformed the treatment landscape for hypertension and heart ailments.
