Abstract:
A drug delivery device retained in the stomach comprising a ring figure made from polymer(s) that may release a drug associated therewith over a controlled, predictable and extended period of time.
Abstract:
A diffusion cell for use in determining the absorption rate of a study substance through a permeable membrane. The cell includes a receptor chamber which contains receptor fluid to receive study substance absorbed through the membrane. The receptor chamber includes a fluid inlet and a fluid outlet. A rotary stirrer is situated adjacent the fluid outlet. The stirrer is rotated so as to rotate the receptor fluid in the receptor chamber in such manner that the fluid pressure is greater at the outlet than at the inlet, so that the stirrer defines a pump which pumps receptor fluid outwardly through the outlet, then through a detector, and then back into the receptor chamber through the inlet. The detector determines the concentration of study substance within the receptor fluid.
Abstract:
Present invention provides a unique drug delivery device for delivering drug by injection into a body. The drug delivery system comprises the drug and polymer which is a liquid at room temperature and a semi-solid or gel at the body temperature.
Abstract:
This invention describes the application of selected polymers as novel drug delivery systems which use the body temperature and pH to induce a liquid to gel transition of the polymer which contains a drug or therapeutic agent therein. The goal of such a delivery system is to achieve a greater degree of bioavailability or sustained concentration of a drug.
Abstract:
A method and drug form are provided for increasing the oral absorption of glycosidic and related antibiotics such as macrolide, aminoglycoside, lincomycin and anthracycline antibiotics and related chemical species by the oral administration of said glycosidic and related antibiotics in a suitable pharmaceutically accepted excipient to which has been added a hydroxyaryl or hydroxyaralkyl acid or salt thereof. The hydroxyaryl or hydroxyaralkyl acid or salt thereof is present in the drug form in quantities sufficient to be effective in enhancing the rate of oral absorption of glycosidic and related antibiotic.
Abstract:
Dichloroamino acid derivatives other than .alpha.-dichloroamino acids are prepared from chlorination of corresponding amino acids, and are found to be potent germicidal and fungicidal agents.
Abstract:
Potassium is rendered nonbitter tasting by combining the same with phytic acid. The final product is useful as a nonbitter tasting potassium supplement for warm-blooded animals deficient in levels of potassium.
Abstract:
Drug-delivery device for releasing a drug at a continuous and controlled rate for a prolonged period of time is comprised of a shaped body of polymeric material containing a pharmaceutically acceptable drug and permeable to passage of the drug by diffusion. The polymeric material is an ethylene-vinyl acetate copolymer having a vinyl acetate content of about 4 to 80% by weight and a melt index of about 0.1 to 1000 grams per 10 minutes.
