Drotaverine (INN, also known as drotaverin) is an antispasmodic drug, used to enhance cervical dilation during childbirth.[2]:283
It is structurally related to papaverine, is a selective inhibitor of phosphodiesterase 4, and has no anticholinergic effects.[3]
It is available in Asian and Eastern European countries under several brand names, with No-Spa being one of them.[4][5]
An article from 2013 described the effects from overdose (in a 19-year-old woman) as including vomiting, seizures and fatal cardiac toxicity.[6]
In 2016, the young Russian chess player Ivan Bukavshin died of a massive overdose (or poisoning) of the drug, which was originally thought to be a stroke.[7]
