Bothrops Bothrops is a genus of the Viperidae family and Crotalinae sub-family of snakes. They are pit vipers, so called because they have a distinctive pit with a heat-detection organ. They are amongst the most venomous snakes known and occur mostly in Central and South America and the Caribbean. The most representative species is the lancehead snake, also the jararaca, its name in Tupi-Guarani. Some of the most common species are: - Bothrops alcatraz - Jararaca-de-Alcatrazes
- Bothrops alternatus - Urutu
- Bothrops ammodytoides - Patagonian lancehead
- Bothrops andianus - Andean lancehead
- Bothrops asper - Terciopelo

Bothropic venom Bothropic venom is extremely toxic and may be lethal in a few hours, depending on the quantity injected and the resistance of the animal or human to it. It acts on a chain of proteolysis of plasma proteins, leading to rapid decrease of blood pressure (hypotension) of the bitten animal and to circulatory shock and death. The physiology, biochemistry and pharmacology of bothropic venom has been extensively studied since the end of the 19th century, mainly by Brazilian scientists after Vital Brazil, who developed at the Butantan Institute in So Paulo the first monovalent and polyvalent antivenoms against it. Rocha e Silva and others have demonstrated that the bothropic venom releases bradykinin, a powerful hypotensive agent. A bradykinin potentiating factor (BPF) has been discovered by Ferreira and collaborators, which led to the development of a new class of antihypertensive drugs, the ACE inhibitors, such as captopril.
