Abstract

Invention is related to field of pharmaceutical preparations, and the present invention relates to a kind of ching-chieh volatile oil to be lyophilized molten, mouth and preparation method thereof, and it includes ching-chieh volatile oil, HP- β-CD, excipients, sweetener, aromatic which, which is lyophilized molten component of mouth,.Preparation method is to prepare ching-chieh volatile oil beta cyclodextrin inclusion complex by using paddling process, after then dissolving inclusion compound, excipients, sweetener, aromatic etc. is added, freeze-drying is prepared into freeze-drying molten, mouth.The molten tablet quality of ching-chieh volatile oil prepared by the present invention freeze-drying mouth is stable, without bad smell, it is convenient to take, absorb rapidly, it is rapid-action.

Description

A kind of the freeze-drying of ching-chieh volatile oil molten, mouth and preparation method thereof
Technical field
The present invention relates to a kind of ching-chieh volatile oil to be lyophilized molten, mouth and preparation method thereof.
Background technique
Ching-chieh is the flower spike of Lamiaceae plant schizonepeta, is spike wheel umbrella inflorescence, is about 0.5cm, irregular segment.Corolla It falls off more, place calyx mitriform, 5 fissure of apex, light brown or yellow green, by pubescence.Pyrene brownish black.Ching-chieh aroma Strong, slightly warm in nature, acrid flavour enters liver, lung channel, be usually used in treat anemofrigid cold, headache, abscess of throat, morbilli, rubeola, sore from the beginning of Deng for a kind of extremely common expelling wind to resolve the exterior Chinese medicine of tcm clinical practice.With regulating blood condition, calmness, analgesia, it is anti-inflammatory, stop blooding, remove phlegm, flat The effects of breathing heavily, is anti-oxidant cures mainly cold, fever, abscess of throat etc. and a variety of skin diseases, and hemostasia effect is aobvious after stir-fry charcoal Write, often haematemesis, bleeding from five sense organs or subcutaneous tissue, hematochezia, metrorrhagia and metrostaxis, in terms of play a role, be tcm clinical practice common drug.
Ching-chieh containing volatile oil be it is faint yellow, have special odor, the influence to air, daylight and temperature is more sensitive, is easy to The disadvantages of decomposed metamorphic is easily vaporized and aoxidizes, and is difficult to control there are stability difference and product quality.Cyclodextrin of volatile oil includes skill Art refers to that volatile oil is contained the technology that inclusion compound is formed in the void structure of cyclodextrin.There are weak phases between cyclodextrin and drug The synergistic effect such as interaction such as Van der Waals force, dipole-dipole interaction, electric charge transfer effect, hydrogen bond, hydrophobic effect, forms Ultra micro cryptomere inclusion compound.After inclusion essential oil, thus it is possible to vary the physicochemical property of volatile oil improves its stability, covers bad gas Taste reduces irritation;Inclusion compound can increase volatilization oil solubility, improve the bioavilability of preparation, improve drug in vivo Absorption, mitigate toxic side effect.Cyclodextrin of volatile oil inclusion compound can be made into the regular dosage forms such as Chinese medicinal tablet, capsule, granule, But these dosage forms need to be delivered with water, it is not easy to gulp down for dysphagia and the inconvenient children that fetch water, old human patient Pharynx, patient's poor compliance.Therefore need to develop a kind of stabilization for being not required to be delivered with water, be easy to swallow, can take whenever and wherever possible Preparation is very important.
Summary of the invention
The object of the present invention is to provide a kind of ching-chieh volatile oil freeze-drying molten of mouth and its preparation method.Solve existing skill The problem of height of bioavilability existing for art, patient's poor compliance.This method prepares ching-chieh volatile oil by using paddling process After then dissolving inclusion compound, excipients, sweetener, aromatic etc. is added in Benexate Hydrochloride, and freeze-drying is prepared into freeze-drying Molten of mouth.The preparation method not only increases the stability of volatile oil, covers pessimal stimulation smell;Drug is improved simultaneously Water solubility works rapidly, and the bioavilability of preparation is high, and convenient to take, patient is easy to receive.
The solution adopted by the present invention to solve the technical problem is that a kind of ching-chieh volatile oil is lyophilized molten, mouth, by weight It is composed of the following components:
The preferred 80-100g of excipients in above-mentioned pharmaceutic adjuvant is selected from gelatin, Arabic gum, xanthan gum, dextrose Acid anhydride, lactose, sorbierite, a kind of either two kinds or more of mixture, the preferably mixture of mannitol and gelatin in mannitol.
The preferred 1-2g of sweetener in above-mentioned pharmaceutic adjuvant is selected from Steviosin, Sucralose, Aspartame, sucrose, honey A kind of middle either two kinds or more of mixture, preferably aspartame.
Aromatic 0.5-1g in above-mentioned pharmaceutic adjuvant is selected from Hami melon essence, flavoring orange essence, strawberry essence, lemonene Essence, flavoring banana essence, a kind of either two kinds or more of mixture, preferably flavoring orange essence in grape powdered flavor.
Above-mentioned ching-chieh volatile oil be lyophilized molten, mouth the preparation method comprises the following steps:
1) ching-chieh volatile oil is dissolved in dehydrated alcohol, volatile oil/ethanol solution is made;Volatile oil/dehydrated alcohol is molten Volume ratio is 1:1;
2) a certain amount of HP- β-CD is weighed, suitable quantity of water is added, dissolves by heating, HP- β-CD saturated aqueous solution is made;
3) it will volatilize oily ethanol solution to be added in HP- β-CD saturated aqueous solution, packet stirred at 40-50 DEG C of constant temperature It closes, mixing speed 200-400r/min, the inclusion time is 2-4h, and the ratio of HP- β-CD and volatile oil is 6:1 (g/ml);
4) step 3 inclusion compound being cooled to room temperature, 3 DEG C of -8 DEG C of refrigeration 12h-24h, is filtered, dehydrated alcohol washs 3-5 times, Each dosage 5mL-10mL;40 DEG C are dried in vacuo -36h for 24 hours, obtain ching-chieh volatile oil beta-CD inclusion;
5) it by ching-chieh volatile oil beta-CD inclusion, is dissolved with purified water, excipients, sweetener, aromatic stirring is added Dissolution, be added mold in, freeze-drying, press mold, packaging to get.
Compared with prior art, the invention has the following beneficial effects:
The present invention combines cyclodextrin encapsulated technique and freeze drying process, not only increases the stability of volatile oil, Cover pessimal stimulation smell;When preparing molten, mouth using freeze-drying simultaneously, without adding disintegrating agent, preparation process is simple Feasible, preparation obtained has obvious skeleton structure character, is disintegrated rapidly in the oral cavity, without grittiness, to overcome use Conventional compression preparation tablet be disintegrated in the oral cavity slowly, have the shortcomings that grittiness.Meanwhile this mouthful of molten convenient to take, patient It is easy to receive, drug can be absorbed into blood by mucous membrane of mouth, pharynx and oesophagus biomembrane, work rapidly, improve biological benefit Expenditure improves the absorption of drug in vivo, mitigates toxic side effect.
