Description

Alkaloid formulations
Technical field
The present invention directly relates to and comprises one or more alkaloidal preparations.Be particularly related to (but being not limited to) and contain the preparation of one or more alkaloids and one or more phosphate derivatives of electron transfer agents.
Background technology
In this description for document, behavior or knowledge to quote or discuss not be to admit that the document, behavior or knowledge or its combination in any are preferential day the time: the part of known knowledge, or the solution of the problem that relates to of known and this description is relevant.
Alkaloid
Alkaloid is as medicinal with a long history.These chemical compounds extract from plant at first, comprise that those have the nitrogen compound of physiological action to the people as medicine and drugs.The term that uses in this specification and claims book " alkaloid " (alkaloid) comprises that all comprise the substituent natural or synthetic reactive compound of primary amine, secondary amine or tertiary amine.Amido can be added in one or two ring, in still non-ring structure is also included within.For example, comprising:
Tertiary amine, it is:
Alicyclic (for example: morphine, atropina, quinine) of three shared nitrogen-atoms of ring; Or
Nitrogen added monocycle and by alkylating circulus (for example: nicotine or fenspiride); Or
The acyclic of adding nitrogen (for example: hydrochloric acid fluorine amine);
The secondary amine that nitrogen is added alicyclic structure (for example: Conline, fendiline) or linear structure (for example: epinephrine);
Primary amine (for example: ephedrine);
Pyridine (for example: nicotine);
Carbonamidine (Methamidine) derivant;
Quinoline (for example: cinchonine);
Guanidine (for example: arginine)
Most of alkaloids are all water insoluble but be dissolved in organic solvent.But all alkaloids all are also can combining with acid of alkalescence forms crystal salt, and this salt is partially soluble in water usually at least.Usually, alkaloid oral or intravenous injection with the form of salt.Alkaloid is the general not medicine of transdermal administration of a class, and this is because the hydrophilic nmature of salt can limit Transdermal absorption usually.For example morphine and atropina are exactly to use in clinical but do not adopt the alkaloid of transdermal administration.In addition, owing to alkaloid is considered to work by lymphsystem, so the alkaloidal oral administration route of expectation improvement.
Topical
Topical is meant directly medicament administration is arrived certain position of health, comprises transdermal administration (being administered on the skin) and buccal (using in the oral cavity).
Skin is the organ of human body maximum, and its function is that the protection internal is not injured by outside chemistry, physics and pathology.Normal skin is divided into three layers: epidermis, corium and subcutaneous tissue.The outside keratinization layer of epidermis is that horny layer has intensity, pliability, high resistance and dry attribute, stops the intrusion and the breeding of microorganism.Horny layer still is the major obstacle of Transdermal absorption.
The transdermal administration technology comprises the independent application of medicine and as the application of preparation, described preparation contains the material that can improve percutaneous absorption rate usually.Transdermal administration Ceng Zuowei ointment, ointment, paste, plaster use in history, so that effectively contact with skin.Afterwards, this technology was through improving, and plaster made " patch " and made it can adhere on the skin better and can control transmission rates better.
It has been recognized that transdermal administration has some potential advantages, these advantages comprise: the level that blood Chinese medicine concentration is reached near slowly vein injection does not but have vein to inject the inconvenience that brings; Compare with oral, better control absorbs and metabolism; Lasting medicine is particularly for short medicine of half-life; Owing to walked around liver first-pass effect, therefore reducing drug dose also can reach equal curative effect; Propellant quantity not sufficient or excessive risk are low; Simplification by dosage regimen obtains better patient dependence.
Be not that all medicines can both reach the medicative blood drug level of systematic treating with sufficiently high speed transdermal administration.For example, molecular weight may be with different speed Transdermal absorption with the approaching medicine of molecular size.Developed the Transdermal absorption that skin promoting agent (skinenhancer) and various preparation technique improve medicine.But caused the concern of people, because the raising of medicine permeability is a cost to destroy the extremely important protective layer of skin to long-term risk.
The various schemes of current improvement transdermal treatments are not success fully also, remains in further improved space.Particularly need to transport the application of alkaloidal transdermal drug delivery system.
People are also increasing to the interest of buccal administration, because the liver metabolism problem that this instructions of taking can produce when having avoided oral drugs.Usually, medicine is made lozenge and place the Sublingual.The oral cavity interior surface layers is not equivalent to the structure of keratodermatitis, therefore the buccal administration is not difficult, and still, this method is not generally adopted, this is because if oral film does not allow to see through or active transport, and transmitance may be lower and can not obtain effective result.For example, international patent application no PCT/AU03/00998 has disclosed a kind of pharmaceutical carrier, this carrier comprises the complex (complex) of the phosphate derivative of medicinal acceptable chemical compound, for example, the amino dipropionic acid tocopheryl phosphate (laurylaminodipropionic acidtocopheryl phosphates) of lauryl alcohol.PCT/AU03/000998 has disclosed tocopheryl phosphate and chelating agent complexation, and described chelating agent is selected from: amphoteric surfactant, cationic surfactant, have the aminoacid of nitrogen functional group and be rich in these amino acid whose protein.Shown that this carrier can improve the topical of Testosterone, estrogen, atropina and morphine.But,, also need further to improve skin and see through for morphine and atropina.
Oral administration
Many medicines all are that employing is oral, are given it up owing to can not pass intestinal wall but large quantities of potential useful medicines are arranged.Be appreciated that material such as fat can see through intestinal wall effectively and transport, transport but have many materials such as tocopherol just to be difficult to see through intestinal wall.Therefore be necessary to provide a kind of drug-supplying system that can improve the alkaloid oral result.

Discuss and conclusion
Data show that the atropina transdermal administration can increase the heart rate of pig, and peak value approximately occurs in uses back 60 minutes.Data show that also basic cream itself can not increase heart rate, and the influence of prepared product comes free atropina itself.
The preparation G that contains tocopheryl phosphate/T2P mixture provides the best system that transports for atropina.Heart rate is accelerated and is compared the persistent period that has kept longer with other preparations.This embodies in Fig. 1 to some extent, the numerical value maximum of G in 0-60 minute and 60-120 minute under " with the difference of baseline " title.It is more effective that table 1 shows that preparation G contains the atropina of the similar concentration in the compositions of lauryliminodipropionate-tocopheryl phosphate consistently.
Data evaluation in the table 2 demonstrates preparation G Log peak value digit rate, Log time of preparation H is had consistent heightening the effect of a treatment to peak value and the important Log rate of rise and Log descending slope.
Also have, preparation of the present invention can not cause inflammation, therefore it seems might allow the contact skin of long period and can not cause inflammation.
Example 2
This case study morphine the transdermal of pig is transported.The skin of pig has the attribute close with people's skin, so pig is the ideal model that research medicine skin transports.
This research is the transdermal that pig carries out morphine to be transported the back postpone evaluation analgesia degree by the withdrawing reaction of measuring tail and being opposite to buttocks thermal source (62 ℃).
With Therapeutic Method and time be fixed model, and the recedence time during with pig, repeated experiments and time zero is stochastic model, by residual maximum likelihood (REML, Residualmaximum likelihood) the method analysis experimental data of shrinking back.Initial Log certificate has been carried out preliminary analysis, but because therefore some deviation data of the 6th hour carry out the Log conversion so that analyze to these data.Two kinds of analyses have all provided essential identical explanation.
Following preparation is tested:
Code Compositions
AGM Morphine is in the preparation G of example 1
AG The preparation G of no morphine
AHM Morphine is in the preparation H of example 1
