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[specify] and Central and Eastern European[specify] countries under several brand names.[4]

An article from 2013 described the effects from overdose (in a 19-year-old woman) as including vomiting, seizures and fatal cardiac toxicity.[5]

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.[6] his doses was 17 mg/kg in the blood stream.


In Israel the product is known under the brand name "No-Spa" by the general public[7] which did not receive a permit to be distributed by the health ministry,[8] However due to high demand local medical counterfeiters had managed to smuggle No-Spa tablets during the years.[8]

In 2008 the Israeli health organization warned consumers from counterfeit No-SPA pills after a smuggler had been arrested at the Ben Gurion Airport with several thousand pills.[9][10]

In 2011 Israeli patent and trade mark office declined the use of the No-SPA.[7]
