What is "gitoformate"

n. A particular cardiac glycoside drug.

Gitoformate ( INN, or pentaformylgitoxin, trade name Dynocard) is a cardiac glycoside, a type of drug that can be used in the treatment of congestive heart failure and cardiac arrhythmia (irregular heartbeat). Produced by Madaus, it is not available in the US, and does not seem to be available in Europe either.
