Abstract
The invention belongs to the technical field of preparations, in particular to a novel sublingual naloxone hydrochloride dripping pill. The invention discloses the sublingual naloxone hydrochloride dripping pill as a medicine for treating the diseases of acute alcoholic intoxication, narcotic analgesic acute intoxication, narcotic analgesic addiction, and the like. The sublingual naloxone hydrochloride dripping pill is prepared from naloxone hydrochloride, dripping pill stroma, a disintegrant and a flavoring agent. The sublingual naloxone hydrochloride dripping pill has the advantages of high bioavailability, quick disintegration, quick effect, simple production technology and low cost and is convenient to take and carry.
Description
Technical field
The invention belongs to the preparation technique field, relate to a kind of new naloxone hydrochloride Sublingual drop pill particularly.
Background technology
Naloxone hydrochloride (NaloxoneHydrochliride) is the derivant of Oxymorphone.Abroad in the nineteen sixty synthetic, applying clinical in 1963, domestic in the nineteen eighty-three synthetic, the analgesia medicine poisoned the specificity antagonism.Be the specific antagonists of opiate receptor, can stop and replace combining of opioid and receptor competitively, remove the opioids poisoning symptom.Discovering afterwards; naloxone hydrochloride can reduce the release of generation, microglia activation and the inflammatory mediator of free radical; improve the energy metabolism of neurocyte; reverse calcium ion, excitatory amino acid rising etc. to neural detrimental effect, and may increase the activity of the endogenous brain protection factor and reach neuroprotective.Clinically, disease such as the naloxone hydrochloride preparation is widely used in treating that anesthetis is excessive, alcoholism, shock, cerebral infarction, cardiopulmonary arrest and respiration inhibition, determined curative effect, side effect is seldom.Because naloxone hydrochloride has above-mentioned effect, so the naloxone hydrochloride preparation more and more is subjected to alcoholism patient's favor in recent years.
The liver first-pass effect of naloxone hydrochloride is strong, and oral administration biaavailability is not good, based on injection, also has sublingual tablet in addition on the present market.Drug administration by injection is very inconvenient, and can incur loss through delay golden hour, and the marketed tablet onset is slower, and bioavailability is low, and market feedback is undesirable.Naloxone hydrochloride of the present invention Sublingual drop pill bioavailability height, disintegrate is rapid, steady quality, produce effects is carried taking convenience fast.Preparation process of the present invention is simple, and the workshop is polluted few, and production process is short, and cost is low.
Summary of the invention
The present invention seeks to overcome the defective of prior art, for clinical treatment provides a kind of bioavailability height, disintegrate is rapid, steady quality, quick produce effects, the medicine naloxone hydrochloride Sublingual drop pill and the preparation technology thereof that carry taking convenience.
The invention is characterized in by naloxone hydrochloride and drop pill substrate, disintegrating agent, correctives formulated.Each composition percentage by weight is: naloxone hydrochloride 0.5%-8%, drop pill substrate 50%-90%, disintegrating agent 1%-8%, correctives 0.5%-40%.
The present invention can be achieved through the following technical solutions:
Naloxone hydrochloride 0.5%-8%, drop pill substrate 50%-90%, disintegrating agent 1%-8%, correctives 0.5%-40% mix homogeneously is pulverized, and sieves, put and be heated to fusion in the heater while stirring, stir the dropping preparation method pill, the water dropper temperature is 80-100 ℃, splashes in dimethicone or other drop pill coolants, and coolant temperature is 0-40 ℃, separate drop pill, absorb coolant, drying, promptly.
Utilize the drop pill of method preparation of the present invention, its beneficial effect is:
1. medicine disintegrate, onset speed is fast, the bioavailability height.The naloxone hydrochloride drop pill is to utilize solid dispersion technology, with medicine and the fusion of drop pill substrate Hybrid Heating, under molten condition, by abundant stirring, drug molecule is dispersed in the substrate.After the system of dripping was finished, medicine was scattered in the substrate with molecularity or superfine crystal state, helps absorption of human body, therefore can effectively improve bioavailability of medicament.
2. drug quality good stability.Because mix homogeneously is abundant, and with short production cycle, drug molecule is evenly distributed in preparation, and is little with the air contact area, is difficult for oxidation, hydrolysis, thus guaranteed drug quality.
3. drop pill production technology, equipment are simple, with short production cycle, the production efficiency height, and production cost is low.
4. dust pollution is few in process of production for drop pill, and the infringement that environment is caused is few, helps labor protection, GMP management, environmental conservation.
The specific embodiment
One, supplementary material
The crude drug of naloxone hydrochloride drop pill is a naloxone hydrochloride.
Adjuvant is that drop pill substrate, disintegrating agent, correctives combine.Drop pill substrate is that one or more are used with in polyethylene glycols, poloxamer, polyoxyethylene stearate (40) ester; Disintegrating agent can be with one or more are used with in carboxymethylstach sodium, polyvinylpolypyrrolidone, cross-linked carboxymethyl cellulose sodium, the hyprolose; Correctives is selected in mannitol, sorbitol, aspartame, Mentholum, the sucrose one or more for use.
Two, preparation method
Naloxone hydrochloride 0.5%-8%, drop pill substrate 50%-90%, disintegrating agent 1%-8%, correctives 0.5%-40% mix homogeneously is pulverized, and sieves, put and be heated to fusion in the heater while stirring, stir the dropping preparation method pill, the water dropper temperature is 80-100 ℃, splashes in dimethicone or other drop pill coolants, and coolant temperature is 0-40 ℃, separate drop pill, absorb coolant, drying, promptly.
Three, prescription design and screening
Substrate is selected:
By naloxone hydrochloride and different substrates prescription, the matrix formulations design sees Table 1, according to the operation of the preparation method in (specific embodiment), drips the system drop pill, and selecting outward appearance, the heavy coefficient of variation of ball, molten diffusing time, hardness etc. is index.Observe the influence of matrix species and contents level thereof to product involved in the present invention.Extramatrical other components of drop pill are set at naloxone hydrochloride, carboxymethyl starch sodium, sucrose.Result of the test sees Table 2.
The design of table 1 matrix formulations
Table 2 different substrates each parametric measurement of filling a prescription
