Title: Gastric-retentive, oral drug dosage forms for the controlled-release of sparingly soluble drugs and insoluble matter
Inventor: SHELL JOHN W
IPC: A61K9/22
Filed: 1997-09-18
Abstract: PURPOSE: Provided are swellable polymer systems designed to deliver sparingly soluble drugs, insoluble or particulate matter and soluble drugs rendered less soluble by hydrophobicity enhancing agents into the gastrointestinal (G.I.) tract. The drug or particulate matter is released into the stomach as the polymer gradually erodes and, thus, the rate at which the drug or insoluble, particulate matter is delivered is determined by the rate of polymer erosion. CONSTITUTION: Controlled-release oral drug dosage forms that comprise a tablet or capsule containing a plurality of particles of a solid-state drug dispersed in a swellable/erodible polymer, such as poly(ethylene oxide) are described. Once ingested, the tablet or capsule disintegrates to disperse the particles within the stomach where they imbibe water to cause them to swell and promote retention in fed-mode-induced patients. As the gastric-retained dosage form gradually erodes, the drug is released in a controlled manner to the stomach for treatment of local disorders, and to the upper gastrointestinal tract where it becomes available for absorption in a controlled and therapeutic manner. Drug-containing vesicles, such as liposomes or nanoparticles or enteric-coated drug particles, can also be delivered to the gastrointestinal tract in a controlled manner using the gastric-retentive dosage forms of the present invention.

Abstract: PURPOSE: A processing chamber of semiconductor manufacturing equipment is provided to improve thin film uniformity on a semiconductor wafer. CONSTITUTION: A process for depositing a thin film on a surface of a semiconductor wafer is proceeded in a processing chamber(10). A susceptor(20) has stages on which semiconductor wafers(50) are placed. A shower head(12) injects a reacting gas to the semiconductor wafer(50) placed on the susceptor(12). A heating apparatus(30) heats the susceptor(20). A lift apparatus loads and unloads the semiconductor wafer(50) from the stages of the susceptor(20). The susceptor(20) is structured into a double type having the first stage(22a) and the second stage(22b). The first stage(22a) and the second stage(22b) of the susceptor(20) are independently heated by heaters(32,34) which are separately installed. Temperatures of the first and second stages are individually controlled. The heaters(32,34) are installed on pertinent portions of the first stage(22a) and the second stage(22b) of the susceptor(20). As a result, the susceptor(20) of double type can minimize ununiformity in temperature. Since the temperature of the susceptor(20) is uniform, uniform heat is transferred to the semiconductor wafer(50) and thus uniformity of the thin film deposited on the surface of the semiconductor wafer(50) is improved.
