CD Formulation - Calcitonin Long-acting Extended Release Microsphere Preparation
FromCD Formulation
Calcitonin long-acting sustained release microspheres preparation steps:
Calcitonin and acidic dextran are prepared together into a solution or pellets of calcitonin and acidic dextran, and then dispersed in an organic solution containing a slow-release or controlled-release polymer to form a suspension; among them, acidic dextran can be carboxylic acid dextran or sulfate dextran, etc., and calcitonin and acidic dextran solution can be an acetic acid solution or hydrochloric acid solution.
