Abstract
Abstract An elastase-containing composition containing 0.5 to 50 parts by weight of sucrose fatty acid ester per part by weight of pure elastase, which composition permits elastase, useful as medicine for arterioscloerosis and hyperlipemia, to be absorbed in increased amount through intenstine.
