- no interaction agent is used
- the eye drops described in this document is not intended for oral administration and neither to undergo a pH change.
- no reference is made to the bioavailability of mequitazine. Indeed, in this document this problem does not arise because it is there local application at the eye and not oral administration.
- solubility is not an obstacle to the formulation of mequitazine because it has significant solubility in a range of acidic pH ranging from 2 to 6.
- a liquid formulation such as that described in FR 2 742 053
- the solubility collapses, and it is in this case that the problem of solubility and bioavailability arises since as said higher, the pH of the intestinal medium is in a range of about 7 to about 9.
- the object of the present invention is thus to provide a solid form of mequitazine having satisfactory solubility in an extended pH range, particularly at basic pH's. So in the cases measured here, the solubility is most often measured at a pH of the order of 9.

- the pH of the intestinal medium varies in a range between about 7 and about 9 and this is where the absorption of mequitazine occurs. Ensuring a particularly increased solubility at these pH is an undeniable advantage of the present invention.
- the solubilization rate of mequitazine alone, that is to say uncomplexed, measured under the same conditions is of the order of 1%.
- the present invention thus makes it possible to multiply the solubility of this molecule by a factor of at least 30, even 60 and even 80.
- an interaction agent to the mequitazine and cyclodextrin complex according to the present invention makes it possible to increase the solubilization of mequitazine.
- the term "interaction agent” is intended to mean any organic or mineral agent improving the physicochemical properties, in particular the solubilization properties in aqueous medium, of the mequitazine / cyclodextrin complex by interactions without covalent bonds with mequitazine included in the cyclodextrin or directly with the mequitazine / cyclodextrin complex.
- the interaction agent is a surfactant, for example sodium lauryl sulphate or Tween, an acid or a base.
- it is an acid or a base.

- the complex thus formed non-covalently associates mequitazine, cyclodextrin and interaction agent.
- the interaction agent interacts according to two plausible hypotheses: strong interactions with mequitazine included in the cyclodextrin and / or strong interactions with the complex formed.
- this interaction agent makes it possible mainly to improve the dissolution properties of the complex in biological fluids, and in particular water, and possibly to increase the rate of inclusion of mequitazine in the cyclodextrin.
- the improvement of the physicochemical properties, in particular in terms of the dissolution of the formed system, may originate - A non-covalent interaction of the interaction agent with mequitazine, cyclodextrin or both (complexation, excepted ).

- it is pure CO 2 or a mixture with an organic solvent conventionally used by those skilled in the art.
- the term "diffusion agent” is intended to mean any solvent which promotes an interaction of mequitazine with cyclodextrin.
- this diffusion agent is chosen from the group consisting of alcohols, ketones, ethers, esters and water with or without surfactant and their mixtures. Even more advantageously, it is water.
- the term "static mode" means a reaction or a process in which all the reagents are simultaneously brought into contact and the reaction is allowed to proceed.
- step (b) of the present invention the complex substances, water and supercritical CO 2 are autoclaved and allowed to react for several hours. The mass of product does not change during the reaction.

- step (a) mequitazine, the interaction agent and the cyclodextrin are introduced in solid or liquid form into a container in which during step (b) ) is injected the dense fluid under pressure and the diffusion agent in carefully chosen proportions.
- the conditions of pressure and temperature as well as the duration of the treatment are defined by any appropriate method.
- the diffusion agent may be added continuously or discontinuously in an amount of between 1 and 50% by weight relative to the total mass of the mixture, preferably between 10 and 25% by weight relative to the total mass of the mixture. .
- step (b) The time required for the molecular diffusion of step (b) is determined by any suitable method. This step (b) can be repeated as many times as desired to obtain a satisfactory dissolution rate. Advantageously, step (b) lasts between about 1 and 16 hours, advantageously 2 hours.
- the pressure of the supercritical fluid is between 0.5 MPa and 50 MPa, advantageously 15 MPa and the temperature between 0 and

- COMPARATIVE EXAMPLE Solubility of racemic mequitazine, L or D taken alone and mixtures Physical mequitazine - beta cyclodextrin and mequitazine - beta cyclodextrin - arginine.
- solubilization rates of mequitazine obtained through the use of the complexes according to the present invention are further compared to the solubilization rates obtained during the simple mixture of cyclodextrin and mequitazine and optionally as an interaction agent, such a mixture is called "physical mixture" and does not correspond to complexes.
- the "physical mixture” corresponds to the simple mixture of the constituents but in an uncomplexed form. It is therefore a question of taking again the molar ratios Méquitazine / cyclodextrines and possibly arginine like agent of interaction implemented for the manufacture of the complexes, and to carry out the tests of solubility on these "physical mixtures".
- Table 1 Mequitazine solubilization rate of the different samples: mequitazine alone, physical mixture simple or in complex with cyclodextrin or with cyclodextrin and arginine.
- FIG. 1 represents the solubilization rates of mequitazine for the various samples tested at 37 ° C. after 15 minutes of stirring for a 2 g / l solution of mequitazine.
- the complexes according to the present invention allow a particularly increased solubility of mequitazine, in this case at pH 9.
- a pH is particularly interesting because it corresponds to the intestinal pH. It is thus noted that mequitazine alone has a very low solubility at this pH.
