Definitions
- the present invention relates to new viscoelastic solutions containing sodium hyaluronate (NaHA) and hydroxypropyl methylcellulose (HPMC). These are biocompatible aqueous solutions, particularly suitable as auxiliaries and / or temporary surgical implants.
- the present invention also relates to the preparation and use of said solutions as auxiliaries and / or temporary surgical implants and as hydration implants.
- Viscoat® by Storz, which contains hydroxypropyl methylcellulose (HPMC).
- HPMC hydroxypropyl methylcellulose
- ophthalmic solutions of modified mucopolysaccharide containing a viscoelastic fraction consisting of hyaluronic acid substituted with acyl groups of 3 to 20 carbon atoms, hyaluronic acid (HA), hydroxypropyl methylcellulose (HPMC) or mixtures thereof. This fraction does not contain chondroitin sulfate.
- HA solutions (of low or high molecular weight) / HPMC (low or high molecular weight) are described, more specifically solutions of this type containing 2% by weight of HPMC and 1% by weight of HA. These solutions have been prepared and tested at the laboratory scale;
- solutions containing a viscous or viscoelastic substance in an aqueous vehicle with controlled pH and osmolality may be chosen from hyaluronic acid or one of its salts and hyaluronic acid mixtures or one of its salts / modified cellulose or modified collagen.
- Hyaluronic acid or one of its salts is present in a proportion of 0.1 to 5%, with a molecular mass of between 0.5 ⁇ 10 6 and 2.5 ⁇ 10 6 ; cellulose or collagen modified at a rate of 0.1 to 5% also.
- WO-A-03 059391 describes a surgical method in which intervene successively: a viscoelastic agent based on a first ingredient (hyaluronate), then a very fluid irrigation solution containing a second ingredient . It does not propose, for use in the context of said surgical method, solutions incorporating said two ingredients.
- the mixtures tested in the examples, representative of mixtures made in situ (inside the eye) are not solutions within the meaning of the invention (the irrigation solution only modifies the surface properties of the viscoelastic agent).
- the mixtures produced in situ are not homogeneous mixtures and, moreover, microbubbles are a priori inexorably generated at the interface viscoelastic agent / irrigation solution.
- the teaching of WO-A-03 059391 does not anticipate or suggest the object of the present invention (solutions, characterized by the nature of their constituents, their respective concentrations and molecular weights (see below), ready for use. 'employment). On the contrary, it can objectively be considered that it removes said object from the person skilled in the art. Said teaching, to use successively two ingredients, is far from suggesting the possibility of previously preparing (industrially) solutions incorporating these two types of ingredients.
- the solutions of the invention are biocompatible viscoelastic aqueous solutions based on a mixture of sodium hyaluronate (s) (NaHA) and hydroxypropyl methylcellulose (s) (HPMC).
- NaHA sodium hyaluronate
- HPMC hydroxypropyl methylcellulose
- the biocompatible viscoelastic aqueous solutions of the invention contain: from 1 to 2% by weight, advantageously from more than 1 to 2% by weight, of at least one sodium hyaluronate, the average molecular mass of which is between 1.10 6 g / ml and 3.5.10 6 g / mol; and
- NaHA sodium hyaluronate
- HPMC hydroxypropyl methylcellulose
- said HPMC develops said surface properties, low concentration involved and a low molecular weight ( ⁇ 1% by weight, preferably ⁇ 1% by wt.) ( ⁇ 110 000 g / mol.).
- a low molecular weight ⁇ 1% by weight, preferably ⁇ 1% by wt.
- the intervention of such HPMC, low molecular weight, low concentration facilitates obtaining the solutions of the invention on an industrial scale.
- the problems of filtration and optical quality of the product remain, under these conditions, quite manageable; a synergistic effect is observed, with such HPMC, on the viscosity. This is particularly interesting in a context of using solutions to maintain spaces or volumes. Indeed, the more the product is viscous and less it is necessary to use to fill a volume. The less we use and the less likely it is to stay in the eye after surgery. The skilled person does not ignore the risks inherent in the non-evacuation of all the product introduced into the eye, risk of elevation of intraocular pressure in particular.
- the viscoelastic aqueous solutions of the invention contain: from 1.2 to 1.8% by weight of at least one sodium hyaluronate, the average molecular mass of which is between 1.6 ⁇ 10 6 g / mol and 3.10 6 g / mol; and
- the lowest concentrations are preferably associated with the highest molecular weights and vice versa (a 1.2% NaHA, with a mean molecular weight of about 3.10 6 g / mol or 1.8% NaHA, average molecular weight of about 1.6.10 e g / mol).
- the solutions of the invention are quite likely to contain at least two sodium hyaluronates of different average molecular weights (between 1.10 e g / mol and 3.5.10 e g / mol) and / or at least two hydroxypropyl methylcelluloses of different average molecular weights (between 10,000 g / mol and 110,000 g / mol).
- sodium hyaluronate of adequate molecular weight between 1.10 e g / mol and 3.5.10 6 g / mol, preferably between 1.6.10 e g / mol and e 3.10 g / mol
- hydroxypropyl methylcellulose of an adequate molecular weight (between 10,000 g / mol and 110,000 g / mol, advantageously between 10,000 g / mol and 50,000 g / mol).
- the solutions of the invention contain:
- the solutions of the invention contain: 0.57% by weight of a hydroxypropylmethylcellulose whose average molecular mass is about 20,000 g / mol.
- the buffer in question is advantageously a phosphate buffer.
- Such a method constitutes the second object of the present invention.
- Sodium hyaluronate (of a suitable average molecular mass of between 1.10 6 g / ml and 3.5 ⁇ 10 6 g / ml or at least two appropriate average molecular weights of between 1.10 6 g / ml and 3.5 ⁇ 10 6 g / ml), generally occurs in the form of fibers while hydroxypropylcellulose (of a suitable average molecular weight of between 10 000 g / mol and 110 000 g / mol or at least two average molecular weights suitable, between 10,000 g / mol and 110,000 g / mol) is generally in the form of powder.
- the purifications are carried out independently of each other in the context of the process of the invention. Below are specified advantageous variants of implementation of said purifications, particularly adapted to the nature of the products in question.
- the filtration step of the mixture is advantageously carried out on at least one 5 ⁇ m filter.
- This filtration step can in any case be carried out under reasonable conditions and within a reasonable time, given the low concentration and molecular weight of P (of) hydroxypropylmethylcellulose (s) present in the solution.
- NaHA fibers (of adequate molecular weight (s)) are dissolved at a low concentration.
- the diluted solutions obtained are filtered through finer and finer filters. In particular, it is recommended to filter them successively on 5 ⁇ m, 1 ⁇ m and then 0.22 ⁇ m filters.
- the purified solutions are then treated so that within them, the purified NaHA precipitates. Precipitation is usually carried out in alcohol. After drying, purified NaHA fibers are recovered.
- Those skilled in the art are aware of this purification process of sodium hyaluronate. A process of this type is hardly applicable to hydroxypropyl methylcellulose which does not have the same solubility characteristics as sodium hyaluronate. To be precipitated, it must be heated; which, in an industrial environment, can lead to bacterial proliferation, a source of endotoxins. In addition, this purification process does not solve the opalescence phenomena.
- the raw material (fibers) NaHA was previously purified (by filtration of a dilute solution thereof, on 5 ⁇ m, 1 ⁇ m and then 0.22 ⁇ m filters);
- the raw material (powder) HPMC has been dissolved in a suitable aqueous solution. Said solution is successively filtered on 5 ⁇ m, 1 ⁇ m and then 0.22 ⁇ m filters;
- the purified NaHA is added, in an adequate quantity, to the filtered solution; it is homogenized;
- the homogenized solution is finally filtered on a 5 ⁇ m filter.
- degassing is intended to rid the viscoelastic solution obtained of small gas bubbles, it is likely to contain.
- the resulting solution is then generally packaged and sterilized. It is usually packaged in syringes.
- the sterilization implemented is likely to modify somewhat the molecular weights of NaHA and HPMC present in the solution.
- the present invention relates to the use of the solutions of the invention as auxiliaries and / or temporary surgical implants and as hydration implants.
- solutions of the invention are particularly effective in this context of use, and are therefore particularly effective in a context of cataract surgery.
- the solutions of the invention are injected, fulfill their function and then recovered at the end of the intervention.
- the outlet of said solutions is not limited to this context.
- hydration implants are also ideally suited as hydration implants, in a context such as meso-lifting. Such hydration implants are injected, fulfill their function and disappear at their injection site. They are metabolized there.
- the solutions of the invention are generally used as is, but it is not excluded that they be added at least one additive, they are loaded with at least one active ingredient ...
- the implants (surgery or hydration) and / or auxiliaries mentioned above therefore consist or consist essentially of the solutions of the invention. It is now proposed to illustrate the invention and highlight the interest by the examples below.
- Examples 1, 2 and 3 show the synergy, announced above on the viscosity.
- the dynamic viscosity of the tested gels was measured with a CARIMED CSL 500 imposed stress rheometer (TA Instrument), at a temperature of 25 ° C, with a cone / plane measuring device (4 cm, 2 °).
- the dynamic viscosity at rest is determined by a measurement at equilibrium under a stress of 1 Pa.
- Example 4 illustrates the problems encountered in filtering HPMC solutions.
- Example 5 shows the importance of the parameters: concentration and molecular weight of HPMC used I 1, on the optical quality of the solution.
- Example 1 Three aqueous solutions were prepared from the following ingredients:
- the first solution containing NaHA, at a concentration of 1.28% by weight, had a resting viscosity of 234 ⁇ 10 Pa ⁇ s.
- Example 2 In the same way, three aqueous solutions were prepared from the following ingredients:
- NaHA fibers with a molecular weight Mw ⁇ 3.10 6 g / mol;
- the first solution containing NaHA, at a concentration of 1.21% by weight, had a resting viscosity of 213 ⁇ 9 Pa ⁇ s.
- the increase in viscosity observed in this case remains greater than expected (synergy) but is more measured than that observed in the previous example.
- aqueous solutions were prepared from the following ingredients: - NaHA fibers, molecular weight Mw ⁇ 2.5.10 6 g / mol;
- HPMC powder sold by DOW, known under the name Methocel, referenced E50, with a molecular weight Mw ⁇ 20,000 g / mol.
- the first solution containing NaHA, at a concentration of 1.5% by weight, had a resting viscosity of 161 ⁇ 2 Pa.s.
- the second containing HPMC, at a concentration of 2% by weight, had a viscosity at rest of 0.05 Pa ⁇ s.
- HPMC Homogeneous solutions of HPMC are obtained by dissolving adequate quantities of powders (Methocel sold by DOW) in phosphate buffer solutions.
- Homogenization is obtained by mechanical stirring at room temperature. After 48 hours of stirring, the solutions are purified, by successive filtrations, until filtration on 0.2 ⁇ m filters.
- WO-A-96 32929 generally more concentrated in HPMC, possibly of higher molecular weight (prepared only on a laboratory scale).
