Ofloxacin vaginal expansion suppository and its preparation method and detection method

Abstract

The present invention relates to a kind of ofloxacin vaginal expansion suppository and its preparation method and detection method, described expansion suppository comprises the drug-containing matrix and expansion carrier that ofloxacin and matrix form; Described ofloxacin and β ring Dextrin forms clathrate, improves the solubility and the stability of ofloxacin; The adding of calcium glycerophosphate in the drug-containing matrix can reduce the hygroscopicity of ofloxacin, increases the stability of suppository; Further described suppository The drug-containing matrix also includes a specific hardening agent; and the ofloxacin vaginal expansion suppository provided by the present invention adopts six original leading technologies, which have the functions of preventing drug liquid outflow, high stability, long-lasting curative effect, and preventing secondary infection, etc. Beneficial effect.

Description

technical field [0001] The invention belongs to the field of vaginal suppositories, in particular to an ofloxacin vaginal expansion suppository and a preparation method and detection method thereof. Background technique [0002] Ofloxacin is a white to slightly yellow crystalline powder; odorless and tasteless; it changes color when exposed to light, and has poor stability; poor water solubility, low absorption, and low bioavailability; it is mainly used clinically for the treatment of bacterial vaginosis. Among the currently marketed preparations, the dosage forms of ofloxacin mainly include tablet, capsule, ointment and suppository; after the tablet is inserted into the vagina, ofloxacin is difficult to dissolve and is difficult to play a role; the same problem exists in the capsule; and the ointment also It is unfavorable for intravaginal use, so the application of suppositories is the most extensive at present, and is accepted by the majority of patients. There are not ...

Problems solved by technology

[0002] Ofloxacin is a white to light yellow crystalline powder; odorless and tasteless; gradually changing color when exposed to light, poor stability; poor water solubility, less absorption, and low bioavailability; it is mainly used clinically for the treatment of bacterial vaginosis

Among the currently marketed preparations, the dosage forms of ofloxacin mainly include tablets, capsules, ointments and suppositories; after the tablets are inserted into the vagina, ofloxacin is difficult to dissolve and play a role; the same problem exists in capsules; It is not conducive to intravaginal use, so suppositories are currently the most widely used and accepted by the majority of patients

There are not many studies on ofloxacin suppositories in the prior art. At the same time, due to the unstable nature of ofloxacin itself, the stability of the suppository is poor after being made; ; The contact surface between the active ingredient and the human body is small, resulting in insufficient absorption, failure to exert the best curative effect of the formula and other technical problems
