Definitions
- the present invention relates to a pnarr ⁇ aceutical formulation in the form of a lyophilisate and containing at least one active principle of non-protein nature. More particularly, the invenuon relates to such a formulation, stable at temperatures which may range from 25 ° C to 40 ° C. which can be sott reconstituted in liquid form by addition of a solvent for the parenteral or oral administration, either directly administered orally, to humans or animals.
- the active principle contained in the formulation according to the invention may be alone or else associated with another active principle of protein or non-protein nature. It is known that lyophilization can have a considerable effect on the degradation of the active pharmaceutical ingredients in a formulation, as well as a strong impact on their stability in lyophilized form.
- the various variables that affect these parameters are mainly the pH, the quantity of salts present, the type and quantity of excipients in the formulation, ie the type of cryoprotection chosen, as well as the temperatures, pressure and time of the freezing, sublimation operations. and drying selected. These different va ⁇ abies influence the physical state of the lyophilisate obtained, namely: glassy amorphous, soft, crystalline amorphous or a combination of these states.
- amino acids preferably glycine
- polyols preferably mannitol
- the literature very rich on the subject, gives no information on the solution of the general problem of obtaining a stable pharmaceutical formulation which takes account of the various parameters which intervene in your operations of formulation and of lyophilization of a non-protein active principle in association with an amino acid and a poiyol. More particularly, your literature teaches that the presence of an amino acid, a polyol, for example mannitol.
- Alanine in crystallized form has the advantage of preventing the collapse of the lyophilisate during sublimation and drying and allowing obtaining a lyophilisate with a greater specific surface area and therefore allows more drying. rapid (Pikai MJ, Freeze-drying of proteins, Biopharm., 26-30 October 1990). Disadvantages linked to the presence of amino acids.
- mannitol in the composition of a lyophilisate is generally justified as a lyophilization ballast, that is to say that it makes it possible both to maintain a solid and rigid structure of the volume of the lyophilisate corresponding to the volume of solution to be lyophilize, but its presence also makes it possible to adjust the reconstituted solution to be injected to isotonia.
- mannitol is the main excipient in the composition of a lyophilisate, it is most often in crystalline form (Lyophiiized formulations recombinant tumor necrosis factor, Hora MS, Rana RK, Smith FW, Pharm. Res., 1992, 9 ( 1), 33-36).
- crystallized solute in a frozen solution is a means of stabilizing proteins during drying (Carpenter JF & Crowe JH, Modes of stabilization of a protein by organic solutes during drying, Cryobiotogy, 1988, 25, 459- 470).
- the crystallization, during freezing, of the excipients predominantly present in a solution to be lyophilized makes the sublimation and secondary desiccation operations more effective, by increasing the specific surface of exchange between the atmosphere of the enclosure of the lyophilizer. and the solid to sublimate. This increase in specific surface area of the crystalline forms compared to the amorphous forms facilitates the heat exchanges during lyophilization.
- crystallized substances have slower dissolution rates than amorphous substances. Indeed, it takes more energy to tear a molecule from an organized network of a crystalline arrangement, than to tear it from the unorganized assembly of an amorphous state. Sometimes the dissolution rate becomes insufficient to allow a sufficiently rapid absorption of these substances, which can cause a reduction in their activity, especially in the context of molecules which are not very stable in solution.
- the heterogeneity of the crystalline phase and the polymorphism obtained for the same substance and between asso ⁇ ées substances induce different dissolution rates for the same substance and between each of the substances, which can lead to non-reproducible therapeutic effects (Galénica 2, Biopharmade 2nd edition, 1982, technique and documentation).
- the loss of activity of a lyophilized protein has been shown to be directly related to the crystallinity levels of the cryoprotective molecule (Izutsu KL, Yoshioka S., Terao T., Decreased protein-stabilizing effects of cryoprotectants due to crystailization., Pharm. Research.
- the amorphous form dissolves faster than the crystallized form and does not have the drawbacks linked to the heterogeneity and polymorphism of the crystallized substances.
- the presence of additives in the amorphous state stabilizes the activity of certain enzymes in proportion to the concentration of the additive according to Izutsu K.L,
- the present invention relates to a lyophilized pharmaceutical formulation consisting of an amorphous phase and a crystalline phase, comprising an effective amount of at least one non-protein pharmaceutical active ingredient, of mannitol and of alanine, the latter two being in a mass ratio R of between 0.1 and 1, R being the ratio between the mass of mannitol and the mass of alanine.
- the active prindpe indus in said formulation remains stable at temperatures which can range from 25 ° C to 40 ° C in lyophilized form. If necessary, the dissolution of the lyophilisate obtained is rapid and complete. The appearance of the lyophilisate is not collapsed and its water content is compatible with the maintenance of the stability of the active principle. It has been shown that, for R between 0.1 and 1:
- the lyophilisate consists of an amorphous phase and a crystalline phase
- the amorphous phase mainly consists of mannitol and active prindpe
- the crystalline phase consists mainly of alanine.
- the object of the present invention is to obtain stable lyophiiisates containing a pharmaceutical active ingredient cryoprotected by an amorphous solid phase constituted wholly or partially by mannitol, this amorphous phase coexisting within the lyophilisate obtained after sublimation and desiccation of the frozen solution, with a crystalline phase consisting essentially of alanine.
- the subject of the present invention is also a process for the preparation of lyophilized pharmaceutical formulations comprising at least one non-protein active ingredient, characterized in that a mixture of said active ingredient, of mannitol and of alanine in which the mannitol and alanine are present in the ratio R of between 0.1 and 1, R being the ratio between the masses of mannitol and of alanine.
- compositions according to the present invention can be introduced into the formulation according to the present invention, such as, for example, buffers or add-bases making it possible to adjust the pH, surfactants, salts, preservatives, in particular antibacterial preservatives, antioxidants or chelating agents with the exception of the expdpients which, in the lyophilisate containing the active prindpe, would prevent the coexistence of the crystalline phase constituted mainly by mannitol and the crystalline phase constituted mainly by alanine, such as for example certain protein derivatives of animal or vegetable origin such as gelatins, dextrins or proteins extracted from wheat or soybean seeds, gums such as agar or xanthan, polyssacharides , alginates, carboxymethylcelluloses, pectins, synthetic polymers such as polyvinylpyrrol idone or complexes of a polyssacharidic nature such as acada gelatin.
- buffers or add-bases making it possible to adjust the pH,
- surfactants which can be introduced into the formulation according to the present invention, mention will be made in particular of polysorbates, poloxamers, tyloxapol, ledthines.

- the preservatives which can be introduced into the formulation according to the present invention, particular mention will be made of methyl and propyl parahydroxybenzoate, benzethonium chloride, sodium mercurothiolate, nitratephenylmercury, benzyl alcohol, phenol and metacresol.
- amorphous mannitol phase and the crystalline alanine phase are independent of the presence and of the concentration of the buffer used to adjust the pH of the solution, but it depends on the ratio R defined above.
- formulation of the solutions to be lyophilized leading to the formulations of the invention are the following:
- One or a combination of active pharmaceutical preparations, a pharmaceutically acceptable buffer for adjusting the pH, of mannitol and of alanine with a mass ratio R mass of mannitol / mass of alanine of between 0.1 and 1, water for injections, as well as, if necessary, antibacterial preservatives and dispensers allowing the solubilization of the active ingredient (s).
- the alanine / mannitol mixture is in the majority.
- the amount of active prindpe present is limited by its solubility in water.
- the formulations of the invention result in fact from the lyophilization of aqueous solutions in which the active substance is perfectly dissolved. Likewise, every ingredient is present in the formulation in an amount less than the amount of the alanine / mannitol mixture.
- the solutions to be lyophilized are prepared as follows:
- the desired amounts of buffer, alanine, mannitol, preservatives and active prindpe are added at the appropriate dissolution temperature to the amount of water for injections or of solubilizing agent necessary for their solubilization until complete dissolution .
- the solutions obtained are filtered in a sterile medium and distributed into reductants, preferably vials or cartridges.
- the lyophilization of the solutions is carried out as follows:
- the solution follows a cycle of freezing, then sublimation and drying adapted to the volume to be lyophilized and to the container containing the solution.
- a freezing speed close to -2 ⁇ C / min is chosen in a Usifroid freeze dryer (France) of the SMH15, SMJ100 or SMH2000 type.
- the times, temperatures and pressures of sublimation and drying are adjusted as a function of the volumes of solution to be lyophilized and of the desired residual water content in the lyophilisate.
- a lyophilisate is then obtained in which the alanine is in crystallized form, and the mannitol in completely or partially amorphous form.
- the lyophilisate can be stored at 25 ⁇ C and even up to 40 ⁇ C without altering the chemical and biological stability of the active prindpe it contains.
