Abstract

Indole-carboxylic acid compounds of the formula: ##STR1## wherein R.sub.1 is lower alkyl or alkoxy radical or halogen; PA1 R.sub.2 is halogen; lower alkyl or alkoxy radical; or PA1 R.sub.1 and R.sub.2 can together also form an alkylene bridge containing 3 to 5 carbon atoms, which can optionally contain one or more double bonds; and, but less preferably, when R.sub.1 is a lower alkyl or alkoxy radical, R.sub.2 can also be a hydrogen atom, and physiologically compatible salts and esters thereof, Are outstandingly effective as blood sugar-lowering agents.
