Abstract

The invention uses super micro shattering and drop pills producing technology to produce fenfluramine drop pills, reaching the purposes such as increasing speed, and dissolution of disintegration, increasing the medicine stability, reducing the dose of auxiliary materials and decreasing cost, with rapid effect and convenient use. It can be buccal as well as deglutition, has remarkable conformity, and is especially suitable for children, older man, sicker in bed or with difficulty of swallowing.

Description

Fenfluramine hydrochloride drop pill and preparation method thereof
Technical field
The present invention relates to a kind of pharmaceutical product and preparation method thereof, specifically fenfluramine hydrochloride drop pill and preparation method thereof.
Background technology
Fenfluramine hydrochloride is the amphetamine appetite suppressant, has the central excitation effect, but intensity a little less than.Can make blood pressure drops, also can increase surrounding tissue to the utilization of glucose and blood sugar lowering also has the effect of triglyceride reducing, cholesterol, total blood plasma lipide.
The fenfluramine hydrochloride oral absorption was good, reached the highest blood drug level through 2-4 hour, and effect was kept 6-8 hour, and 18-30 hour its half-life, blood level can reach stable state after 3-4 days, produced curative effect.Most of with the slowly discharge from urine of metabolite form.List marketing at present tablet, the clinical obese patient who is used for Simple Obesity and suffers from diabetes, hypertension, cardiovascular disease, anxiety neurosis only arranged.
The fenfluramine hydrochloride odorless, in water, dissolve, but its disintegration of tablet time is long, dissolution and dissolution rate are low, absorption difference, and bioavailability is low, the supplementary product consumption ratio is big, child, old people, bed patient and dysphagia patients are taken inconvenience, and compliance is poor, have influenced the performance of fenfluramine hydrochloride therapeutical effect.
The present invention makes the fenfluramine hydrochloride drop pill by using ultramicro communication technique and dropping pill formulation Technology exactly, thereby overcomes the above defective of fenfluramine hydrochloride tablets, and the therapeutical effect of fenfluramine hydrochloride is given full play to.
Summary of the invention
The fenfluramine hydrochloride drop pill of making by using ultramicro communication technique and dropping pill formulation Technology not only have disintegrate molten loose fast, dissolution and dissolution rate improve, steady quality, the pill volume is little, both can swallow also can buccal, easy to carry and use, onset is rapid, compliance is good, be particularly suitable for the characteristics that child, old people, bed patient and dysphagia patients are taken, but also have working condition and production equipment is simple, production cost is low, compare the advantage that supplementary product consumption reduces with tablet, demonstrated fully the new drug research exploitation spirit that people-oriented.
For achieving the above object, the present invention by the following technical solutions: the fenfluramine hydrochloride fine powder of 1 weight portion through micronizing is added in 1~10 weight portion molten matrix, fully mixing, dropping preparation method is condensed into ball in coolant, remove coolant, drying, promptly.
The chemical name of fenfluramine hydrochloride is N-ethyl-Alpha-Methyl-3-trifluoromethyl-phenethylamine hydrochlorate among the present invention, and structural formula is Molecular formula is C 12H 16F 3NHCl, molecular weight are 267.72.
Substrate among the present invention includes but not limited to polyethylene glycol 6000, Macrogol 4000, polyethylene glycol 1500, cetomacrogol 1000, sodium stearate, glycerin gelatine, poloxamer, stearic acid, glycerol monostearate acid, insect wax etc.
Coolant among the present invention includes but not limited to dimethicone, liquid paraffin, vegetable oil, water, alcoholic solution etc.
Below through detecting to beneficial effect of the present invention as directed
One, detects index and method
1. disintegrate (molten loosing) time limit: check according to inspection technique disintegration (two appendix XA of Chinese Pharmacopoeia version in 2000).
2. dissolution rate: sample thief, according to dissolution method (two appendix XC first methods of Chinese Pharmacopoeia version in 2000), with 0.1mol/L hydrochloric acid solution 900ml is solvent, rotating speed is that per minute 100 changes, and operation in accordance with the law is in the time of 10,20,30,40 minutes, get solution 10ml, filter, get subsequent filtrate, as need testing solution; Other gets the fenfluramine hydrochloride reference substance, with 0.1mol/L dissolve with hydrochloric acid solution and dilution, makes reference substance solution.According to spectrophotography (two appendix VI of Chinese Pharmacopoeia version in 2000 A), measure trap at the wavelength place of 263nm, calculate stripping quantity.
