- WO2004 / 084883 discloses the use of an isotretinoin complex with cyclodextrins for the preparation of a pharmaceutical composition for oral administration.
- Adapalene is recognized as a drug as effective as tretinoin for the treatment of acne, but having the advantage of causing fewer adverse effects than this one; making it a product of choice. There is therefore a need for a topical pharmaceutical composition containing adapalene, the formulation of which is stable, well tolerated and which optimizes the penetration of adapalene into the skin.
- a formulation as described in the present application makes it possible to solubilize adapalene and gives good tolerance and chemical stability results at ambient temperature, with improved penetration into the skin. This makes it possible, if necessary, to reduce the quantity of active ingredient administered.
- the Applicant has also developed a method of manufacturing the composition according to the invention and thus solubilization of adapalene in aqueous medium.

- Cyclodextrins are cyclic oligosaccharides consisting of ( ⁇ -1, 4) ⁇ -D-glucopyranose units with a lipophilic central cavity and a hydrophilic external surface (Frémming KH, Szejtli J: "Cyclodextrins in pharmacy", Kluwer Académie Publishers, Dortrecht, 1994).
- Cyclodextrins are known to increase the solubility of molecules by forming a "cage" shaped structure having a hydrophilic portion external and an internal hydrophobic part. Cyclodextrins can thus form inclusion complexes with many drugs by accepting inside the cavity the whole molecule, or more commonly the lipophilic part of the molecule.
- cyclodextrins The most abundant natural cyclodextrins are ⁇ -cyclodextrins, ⁇ -cyclodextrins and ⁇ -cyclodextrins.

Furthermore, not all products are suitable for complexation with cyclodextrins. Many products can not be complexed or complexation provides no essential benefit. Inorganic compounds are generally unsuitable for complexing with cyclodextrins.
