Novel pyrrolecarboxylic acid derivatives represented by the following formula: ##STR1## where R.sup.1 is a hydrogen atom, an alkyl group of 5 to 25 carbon atoms or an alkenyl group of 5 to 25 carbon atoms, R.sup.2 is a hydrogen atom, a phenyl group or an optionally substituted alkyl group of 1 to 10 carbon atoms, and R.sup.3 is a hydrogen atom, an alkyl group of 5 to 25 carbon atoms or an alkenyl group of 5 to 25 carbon atoms, or pharmaceutically acceptable salts thereof are provided. The compounds are highly effective in reducing the level of triglyceride or cholesterol in serum, and useful as an active ingredient of a pharmaceutical composition for treating hyperlipemia and arteriosclerosis.
