Abstract
The present invention relates to a parenteral drug delivery carrier and a drug delivery system that use a thermosensitive gel based on methyl cellulose alone as a low molecular weight polysaccharide without a salting-out salt. The single use of the low molecular weight methyl cellulose as a natural polymer increases the biocompatibility and biodegradability of the drug delivery system. Therefore, the drug delivery system is suitable for use in the preparation of a sustained release composition for parenteral drug delivery.
