MODIFIED GASTRORETENTIVE DRUG DELIVERY SYSTEM FOR AMINE DRUGS

摘要

Oral dosage forms for basic amine drugs, the dosage forms having a gastro-retentive component and a non gastro-retentive component. These dosage forms are capable of providing both IR and SR release rates for these drugs. In addition, they provide for release of the drug in the stomach and/or intestine of a mammal to which such dosage forms are administered. Such dosage forms include tablets and capsules. Such dosage forms provide improved bioavailability of otherwise poorly bioavailable basic amine drugs.
