Title: Starch-based release modifying excipients and pharmaceutical compositions derived therefrom
Inventor: MARC LEMIEUX
IPC: A61K47/36
Filed: 2017-10-16
Abstract: An extended release dosage form (ERDF) comprising a release modifying excipient comprising a high amylose starch, a cross-linked hydroxypropylated amylopectin and a pre-gelatinized common starch; wherein the release modifying excipient is substantially free of crosslinks between amylose and amylopectin and substantially free of crosslinks between amylose and amylose. In an embodiment, the dosage form is formulated into an extended release tablet using tramadol as the active ingredient. In a preferred embodiment the ERDF is used in a bi-layer tablet containing both immediate and extended release layers where both layers contain the active acetaminophen. The extended release properties of conventional cross-linked high amylose starches can be reproduced by intimately mixing i) cross-linked chemically modified amylopectin; ii) a high amylose, non-chemically modified starch and; iii) a pre-gelatinized common starch. Producing a release modifying excipient in this way means that no chemical cross linking between (a) amylose and amylopectin or (b) amylose and amylose has occurred.

Abstract: A thermocouple type liquid level measurement system comprises a plurality of heater-attached thermocouples 4a-4d as sensor units 5a-5d where a thermocouple and a heater arranged in the vicinity of the thermocouple are housed in a same sheath to measure a liquid level in a container 1. The thermocouple type liquid level measurement system includes a battery 17, a first liquid level measurement device 12 which determines liquid level based on a temperature difference between adjacent sensor units; a second liquid level measurement device 13 which determines liquid level from the temperature rise amounts from the start of energisation to the end of energisation of the heaters of the sensor units; and a measurement control device 15 which selects and operates one of the first liquid level measurement device and the second liquid level measurement device to determine the liquid level. The measurement control device performs selection either in response to operator input (manually), or switches automatically according to residual electric power of the battery or whether a level determination is possible using the first liquid level measurement device. The system may be used to measure water level of a spent fuel storage pool of a nuclear power plant. In the event of a nuclear plant emergency requiring use of battery power, the level measurement system is able to continue measuring level for longer by saving battery power by not using the heaters when the liquid level is determined by the first liquid level measurement device.
