Well, I beg to differ with "huh1051" regarding the snake venom. This is straight from "Wikipedia"...[edit] History/brand names
Lisinopril was developed by Merck & Co. and is marketed worldwide as Prinivil or Tensopril and by AstraZeneca as Zestril. In India it is marketed by Micro Labs as Hipril. In the United States, a generic version is available. Like other ACE inhibitors, it is derived from the venom of the jararaca, a Brazilian pit viper (Bothrops jararaca). So, "what" do you believe!!!???? This drug breaks the blood brain barrier which is probably why so many people get depression. However, I "think" this drug is causing more than just depression. It's shrinking the brain and affecting memory.
