enteric coating if only a portion of this enzyme in the composition is enterically coated the uncoated enzyme is upon ingestion immediately available for hydrolysis of lactose in the stomach while the enterically coated enzyme is available for lactose hydrolysis in the intestines the lactase compositions of the present invention can be combined with a pharmaceutically acceptable carrier and administered orally the unit dosages of these compositions may be in the form of solid preparations such as tablets pills capsules caplets powders granules and wafers or liquid preparations such as suspensions or dispersions in aqueous or non aqueous vehicles such as syrups and elixirs in preparing solid unit dosage forms the first and second lactases are mixed with conventional solid fillers or carriers such as starch talc calcium phosphate calcium sulfate calcium stearate magnesium stearate stearic acid sorbitol mannitol gelatin natural or synthetic gums such as carboxymethylcellulose methylcellulose alginates dextrans acacia gum karaya gum locust bean gum tragacanth and other conventional carriers additionally other excipients such as diluents binders lubricants disintegrants colors and flavoring agents may be employed suitable liquid forms of the present invention can be prepared by incorporating the lactase in aqueous or nonaqueous dispersions suspensions or solutions conventional liquid carriers such as glycerol and edible glycols edible oils such as cottonseed oil soybean oil corn oil peanut oil safflower oil and other triglyceride oils and dispersing or suspending agents.
