, as measured on rat intestine, when applied to at least one surface of a pharmaceutical dosage form for oral delivery of a drug, result in a gastrointestinal retention time of at least 4 hours in a fed beagle dog model, during which the drug is released from the dosage form.
Multi-layer tablets, particularly those including hydrophobic excipients, are useful in administering hygroscopic and/or deliquescent drugs. In addition, varying the amount of drug in multi-layer tablets allows the release rate of the drug to be controlled.

A drug form is provided for increasing the oral absorption of β-lactam antibiotics such as the penicillins, cephalosporins and related chemical species by the oral administration of said β-lactam antibiotics in a suitable pharmaceutically accepted excipient to which has been added a hydroxy aryl or hydroxy aralkyl acid or salt, amide or ester thereof. The hydroxyaryl or hydroxyaralkyl acid or salt, amide or ester thereof is present in the drug form in quantities sufficient to be effective in enhancing the rate of oral absorption of the β-lactam antibiotic.
An object of the present invention is to obtain an oral glycyrrhizin preparation not only manufacturable by a simple method but also having an excellent property of being absorbed from the digestive tract. In the present invention, such oral preparations are made into enteric forms wherein glycyrrhizin is admixed with an effervescent agent in combination with an absorption enhancer such as a medium-chain fatty acid or a salt thereof. In the preparation of the present invention, it is now possible to achieve an excellent absorption of glycyrrhizin from the digestive tract by addition of an effervescent agent and, moreover, the preparation can be manufactured by a simple, convenient method without special steps.

The present invention relates to a non water-soluble pharmaceutical carrier which adheres to mucosal surfaces and body tissues upon application and forms a film, providing protection and delivery of pharmaceutical to the site of the application, surrounding body tissues, and bodily fluids. The gel comprises a volatile or diffusing nonaqueous solvent and at least one non water-soluble alkyl cellulose or hydroxyalkyl cellulose. A bioadhesive polymer may also be added. The gel provides an effective residence time with ease of use. The residence time may be adjusted by adding a component which acts to adjust the kinetics or erodability of the carrier.
