Abstract
The invention discloses a kind of analysis methods for measuring Quetiapine fumarate sustained-release tablets release, about measurement Quetiapine fumarate sustained-release tablets release, dissolution medium in the release method is made of water, buffer salt and surfactant, using liquid chromatography analysis test sample.The quetiapine fumarate burst size in the release experimentation of Quetiapine fumarate sustained-release tablets can be improved in dissolution medium in the measuring method, establishes suitable chromatographic condition, achievees the purpose that analysis.
Description
Technical field
Present invention relates particularly to a kind of analysis methods, measure the release of Quetiapine fumarate sustained-release tablets.
Background technique
A kind of nerve drug of Quetiapine fumarate sustained-release tablets, can be used for treating feature and the disease of idiopathic parkinsonism
Shape.The chapters and sections of Quetiapine fumarate sustained-release tablets are not included in Chinese Pharmacopoeia temporarily, are delayed in United States Pharmacopeia about quetiapine fumarate
Releasing piece release is after being tested 4 hours using the buffer solution of the pH4.8 of 900ml as dissolution medium, and reconvert is to 1000ml's
In the buffer solution of pH6.6, it is measured using<711>first method basket method of United States Pharmacopeia.Pass through biology to what we developed
The Quetiapine fumarate sustained-release tablets (200mg) of equivalence preliminary experiment are tested according to above-mentioned release method, in the release
Under the conditions of, it is not achieved 80% in the release at 24 hours the last one time points, does not reach the requirement discharged substantially.Fumaric acid
Quetiapine is water-soluble fine substance, and in 6.6 phosphoric acid solution of pH, solubility > 0.77mg/ml meets sink conditions.
Basic release is not reached under this method this is because having the hydroxypropylcellulose of 50% high viscosity specification, meeting in the prescription developed
Swelling causes drug that cannot be released under this condition.Therefore a new dissolution medium is developed, hydroxypropyl containing high viscosity is made
The Quetiapine fumarate sustained-release tablets of cellulose reach release (> 85%) completely in release experimentation has realistic meaning.
