Definitions
- the active ingredient may be encapsulated within a phospholipid vesicle or immobilized in microspheres of biodegradable polymer.
- the delivery of active ingredients through the skin has many advantages. Variable rates of absorption and metabolism associated with oral therapy are avoided, as well as possible gastrointestinal irritation.
- the delivery of the active ingredient transcutaneously also allows better control of blood levels.
- the skin has a complex structure and molecules administered transcutaneously or topically must first cross a barrier formed by the stratum corneum before reaching the blood stream.
- the stratum corneum consists of a dense and highly keratinized layer with an average thickness of 10-15 microns.
- the high degree of keratinization, as well as the compact assembly of the cells can constitute a virtually impermeable barrier to the passage of an active ingredient.
- the rate of permeabilization through the skin is extremely slow.
- Many additives can be used to increase the rate of penetration of the active ingredient through the skin.
- Most of the compounds are administered at the same time as the drug (in some cases the skin may be pretreated with a permeabilizer) so as to increase the permeability of the stratum corneum and thereby increase the penetration of the active ingredient through the skin.
- the permeability of many therapeutic agents can be improved by these permeabilizers.
- Several additives are able to promote the transport of active ingredients through the skin according to several mechanisms, the most important of which are:
- Permeabilization agents can be classified into different categories. Solvents such as alcohols, methyl sulphoxides and polyols increase the solubility which increases the skin passage. In addition, some solvents such as dimethylsulfoxide (DMSO) or ethanol, will extract the lipids and make the stratum corneum more permeable. Oleic acid and isopropyl myristate are typical examples of permeabilization agents that disrupt the stratum corneum by intercalating into the lipid structures. This emollient effect thus increases the diffusion coefficient of the active ingredient. Also, ionic surfactants or DMSO interact with the keratin of corneocytes, which deploys the structure of the protein and increases the diffusion coefficient.
- DMSO dimethylsulfoxide
- ethanol ethanol
- Oleic acid and isopropyl myristate are typical examples of permeabilization agents that disrupt the stratum corneum by intercalating into the lipid structures. This emollient effect thus increases the diffusion coefficient of the
- the present invention describes an original strategy of actively involving the active ingredient in its own transport. This intermolecular association will aim to protect, solubilize and convey the drug to the action site.
- it is proposed to associate, by simple electrostatic acid / base interaction, an acidic active ingredient with a biocompatible basic amphiphilic molecule. This combination can be stabilized by hydrophobic type interactions between the active ingredient and the amphiphilic molecule.
- this invention relates to formulation applications, such as solubilization, transport, protection and transcutaneous diffusion of an active ingredient. Indeed, this amphiphilic molecule may also act as a permeabilization agent for transcutaneous transport.
- the invention relates to the combination of a biocompatible basic transporter with an active ingredient comprising one or more acid functional groups.
- This intermolecular association leads to a new amphiphilic species corresponding to the formation of an acid / base pair bound by electrostatic interactions and stabilized by Van der Waals interactions between the hydrophobic parts of the two constituents.
- the amphiphilic complex thus formed by association leads, according to its concentration in water as well as the nature of the active ingredient (volume, hydrophobicity), to a set of self-assembled structures such as micelles or vesicles.
- the objects thus formed can also be used for the self-transport of the active ingredient.
- the present invention thus relates to an association complex formed between an amphiphilic molecule and an active ingredient.
- the object of the present invention is an intermolecular association complex of formula (I) of an amphiphilic transporter and an active ingredient " ZY:
- S represents a carbohydrate residue selected from the group consisting of monosaccharides, disaccharides, polysaccharides, polyols and combinations of these residues,
- X represents a C 1 -C 12 aliphatic residue chosen from alkyl, alkene, alkyne, linear or branched, or an ethylene oxide or propylene oxide unit having a degree of polymerization of between 1 and 10, as well as all the combinations of these residues,
- n 0 or l
- R 1 represents H
- R 2 , R 3 independently represent a hydrogen atom or a linear or branched C1-C20 or perfluorinated hydrocarbon chain, as well as all the combinations of these substituents, and in which the active ingredient
- Y carrying the therapeutic or pro-therapeutic activity, chosen from the group comprising anti-inflammatories, antibiotics, polyunsaturated fatty chain, vitamins or pro-vitamins and a residue
- Z acid selected from the group consisting of carboxylates, sulfates sulfonates, phosphates, phosphonates or phosphinates.
- the present invention also relates to the use of a complex as defined above to protect, solubilize and / or convey an active ingredient.
- the invention also relates to the use of a complex as defined above for the manufacture of a medicament intended for topical or transcutaneous administration.
- the transporter is selected from biocompatible amphiphilic molecules having one or more basic functions.
- amphiphilic transporter will be chosen from carbohydrate derivatives having one or more hydrophobic chains, as well as one or more basic functions capable of interacting electrostatically with the active acidic principle.
- This amphiphilic carrier has the general formula (II):
- S represents a carbohydrate residue selected from the group consisting of monosaccharides, disaccharides, polysaccharides, polyols and combinations of these residues,
- X represents a C 1 -C 12 aliphatic residue, alkene, alkyne, linear or branched, or an ethylene oxide or propylene oxide unit with a degree of polymerization of between 1 and 10, as well as all the combinations of these residues,
- n 0 or 1
- R 1 represents H
- R 2 and R 3 independently represent a hydrogen atom or a linear or branched C1-C20 or perfluorinated hydrocarbon chain, as well as all the combinations of these substituents.
- the amphiphilic transporter will advantageously be chosen from sugar-chain and long-chain amino surfactants, such as N- alkylamino-1-deoxylactitols having a chain with 12 or 16 carbon atoms, which will be named respectively Lhydl2 and Lhydl ⁇ .
- N-alkylamino-1-deoxylactitols is as follows:
- the active ingredient will preferably be chosen from non-steroidal anti-inflammatory drugs (NSAIDs) carrying an acid function, such as ketoprofen, ibuprofen or indomethacin.
- NSAIDs non-steroidal anti-inflammatory drugs
- the complexes according to the present invention may advantageously be used to solubilize and transport by acid / base combination polyunsaturated fatty acids (PUFAs) such as linoleic acid or linolenic acid.
- PUFAs polyunsaturated fatty acids
- the intermolecular combination (stoichiometric or not) will be formed by simple contact in water or in another solvent, the amphiphilic molecule in its basic form with the active ingredient in its acid form .
- the invention therefore relates to a combination by simple neutralization acid / base between the amphiphilic transporter in its basic form and the active ingredient in its acid form.
- the invention also relates to a process for preparing the present complexes.
- the stoichiometric mixture of amphiphilic carrier and active principle is advantageously reacted by heating it at a temperature between room temperature and the boiling point of the solvent at atmospheric pressure, and for a duration of 1 to 72 hours. .
- the final mixture is freed from its water, preferably filtered and freeze-dried.
