Definitions
- the present invention relates to methods of solubilising an agent, eg biologically active materials, in an amphiphile.
- an agent eg biologically active materials
- the invention relates to methods of bringing biologically active substances used for topical administration into association with permeation aids.
- solubilisation it is a continuing objective of the pharmaceutical industry to achieve high degrees of solubilisation of biologically active materials in a variety of solvents. There are several reasons for this need to achieve solubilisation. For instance, achieving solubilisation in particular solvents may improve bioavailibility. An example of this would be the solubilisation of biologically active materials in oils. Examples of methods to achieve this can be found , for example, in WO 95/13795, WO 96/17593 and WO 96/17594.
- the present invention provides a method of solubilising an agent in an amphiphile which method includes the steps of:
- step (iii) heating the residue from step (ii) ;
- step (i) the agent and the amphiphile can suitably be brought into association with each other by firstly dissolving each one separately in the common solvent, followed by mixing of the two resultant solutions.
- the removal of the solvent should be carried out at a temperature such that the amphiphile/agent residue which remains is in the solid state.
- the heating step should then be sufficient to melt the solid amphiphile, and also to convert the amphiphile/agent array from an "open" form to one which is more condensed.
- the common solvent can be water, for example, and it can be removed in step (ii) by, e.g. freeze drying, centrifugal vacuum drying or any other suitable method.
- the amphiphile will be a phospholipid, for instance lecithin, a glycolipid, a polyoxyethylene containing surfactant, a lipophilic sulphate, betaine, a sarcosine containing surfactant, Solulan 16, Solulan C24 , polyoxyethylene 40 stearate, one of the Tween series of surfactants, one of the Span series of surfactants or a pegolated castor oil derivative, e.g. Cremaphor EL35.
- the "agent” is suitably a hydophilic species which is generally soluble in aqueous solvents but insoluble in hydrophobic solvents.
- the range of hydrophilic species of use in the present invention is diverse but hydrophilic macromolecules represent an example of a species which may be used.
- macromolecules are suitable for use in the present invention.
- the macromolecular compound will be hydrophilic or will at least have hydrophilic regions since there is usually little difficulty in solubilising a hydrophobic macromolecuie in oily solutions.
- suitable macromolecules include proteins and glycoproteins, oligo and polynucleic acids, for example DNA and RNA, polysaccharides and supramolecular assemblies of any of these including, in some cases, whole cells or organelles. It may also be convenient to co-solubilise a small molecule such as a vitamin in association with a macromolecuie, particularly a polysaccharide such as a cyclodextrin. Small molecules such as vitamin B12 may also be chemically conjugated with macromolecules and may thus be included in the compositions.
- Other macromolecules may be used are FITC-labelled dextran and RNA extract from Torulla yeast .
- the process of the present invention is of use in solubilising smaller organic molecules.
- small organic molecules include glucose, carboxyfluorescin and many pharmaceutical
- agents for example anti-cancer agents, but, of course, the process could equally be applied to other small organic molecules, for example vitamins or pharmaceutically or biologically active agents.
- compounds such as calcium chloride and sodium
- phosphate can also be solubilised using this process.
- the present invention would be particularly advantageous for pharmaceutically and biologically active agents since the use of non aqueous solutions may enable the route by which the molecule enters the body to be
- an inorganic material such as a small inorganic molecule or a colloidal substance, for example a colloidal metal.
- a colloidal metal such as colloidal gold, palladium, platinum or rhodium
- the above-described method is particularly suitable for achieving association between an agent which is for topical administration and a permeation aid.
- An example of the former is Zinc Acetate (ZnAc 2 ) .
- amphiphiles are those which are solid at room temperature, eg Solulan 16 and Solulan C24.
- the present invention provides:
- composition comprising an agent solubilised in an amphiphile obtainable by any of the methods described herein, particularly an agent for topical administration solubilised in an aphiphile which is a permeation aid; and
- composition of the invention in the preparation of a medicament for topical administration, particularly a composition for use in the treatment of inflammation and/or arthritis wherein the active agent is ZnAc 2 .
- a solution of zinc acetate at a concentration of lOOmg/ml was prepared by addition of lOOmg of ZnAc 2 to 1ml of distilled water, and mixing at RT until dissolution was achieved.
- a solution of Solulan 16 at a concentration of lOOmg/ml was prepared by addition of 500mg of Solulan to 4.5ml of distilled water and mixing at 60°C until dissolution was achieved.
- a solution of Solulan C24 at a concentration of lOOmg/ml was prepared by addition of 500mg of Solulan C24 to 4.5ml of distilled water and mixing at 60°C until dissolution was achieved.
- a virus suspension (Sabin strains, Types 1, 2, 3) containing 5xl0 8 particles/ml (spun to remove contaminating protein) was diluted 50-fold by addition of 200 ⁇ l of the suspension to 9.9ml of distilled water, yielding a concentration of 10 7 particles/ml.
- the suspension was divided into four equal aliquots of 2.5ml, and dispensed into 7ml screw-capped glass vials.
- 2.5ml of distilled water was added to one aliquot of virus particles and this group was labelled "W” .
- 2.5ml of Solulan C24 (lOOmg/ml) was added to another aliquot and mixed gently. This group was labelled "S”.
- the suspensions prepared as described herein were used to perform 10-fold dilutions in Vero cell cultures,to measure the viability of the polio virus present. The results were expressed as the highest dilution at which 50% cytopathic effects were observed.
