Definitions
- the present invention relates to a method of manufacturing a tablet including a morphine-type analgesic and the tablet obtained.
- Morphine derivatives are indicated in the treatment of moderate to severe pain in adults.
- the analgesic effect is obtained thanks to an activity on morphine receptors, preferably mu receptors, associated with an inhibitory activity on the neuronal reuptake of serotonin and noradrenali e.
- morphine derivatives there may be mentioned inter alia morphine, codeine, pethidine, dextropropoxyphene, methadone, nefopam.
- tramadol a compound marketed under the name tramadol.
- the advantage of this molecule is to use it in therapy in a galenic form called sustained release. This makes it possible to reduce the number of takes, to obtain a continuous effect and substantially proportional to the time at place of immediate release or at best over a very short period of time.
- This prolonged release also makes it possible to limit the side effects by eliminating the main peaks of doses engendered by rapid releases, thus making it possible to limit the side effects that can cause temporary overruns of admissible doses.
- this type of analgesic which is not currently treated, it is that of the slowing of the intestinal transit caused by the taking of tramadol, in particular.
- this active principle acts on morphine receptors and we know that they are localized at the central level and responsible for regulating the perception of pain and also at the level of the intestinal mucosa.
- the present invention provides a method for manufacturing a tablet containing an analgesic, more particularly a morphine derivative such as tramadol which limits this side effect on intestinal transit without harming the effectiveness and the diffusion of the active principle.
- the invention also covers the tablet obtained.
- Tablet formulations are known in particular from US Patent No. 6,149,940 which describes a tablet with a controlled release formulation.
- the teaching disclosed consists in proposing a tablet with several layers.
- the first layer consists of a compound of hydrophilic polymers which swell on contact with aqueous biological fluids.
- the second layer is juxtaposed and includes additives allowing a compressibility suitable for releasing alfuzosin hydrochloride over a determined period of time.
- the swelling kinetics remain long and the volume increase is reached after several hours.
- the retention is based on the fact that the swelling must substantially lead to a tripling of the size and undergo mechanical retention at the pylorus.
- Such an arrangement requires the superposition of at least two layers, which is particularly difficult to manufacture.
- it is a mechanical retention or the pylorus has dimensions and rates of contraction which can vary sufficiently from one individual to another to not allow to determine satisfactorily a residence time precise in the stomach.
- the dose of active ingredient is of the order of 10 mg whereas in the case of tramadol, the doses are high of the order of 25 to 500 mg.
- FIG. 3 represents a table with a constant composition and different hardnesses
- the aim of the process consists in producing a form with gastric residence which maintains tramadol in the upper part of the digestive tract.
- the release and absorption of the active ingredient will mainly take place in this upper part, limiting the atony of the intestinal muscles responsible for constipation.
- the method according to the present invention consists in producing a monolithic, homogeneous tablet which uses low density excipients in order to provide the tablet with immediate buoyancy, these same excipients allowing a controlled release of the associated active principle, in this case tramadol or its salts, dosed between 25 and 200 mg per tablet.
- the excipients are chosen from derivatives of hydroxypropylmethylcellulose, more particularly that having a molecular mass of between 1000 and 4,000,000. The proportion of this excipient is between 30 and 99% by weight of the finished tablet. It is also possible to use derivatives of polyvinyl acetate and of povidone known under the trade name of Kollidon SR, always in the same proportions.
- a dry or wet granulation route or direct compression is used, which is the best embodiment.
- the active principle and the excipients used are preferably but not necessarily sieved before mixing.
- the particle size of the active ingredient is between 10 and 500 ⁇ m and preferably slightly close to 150 ⁇ m.
- Hydroxypropyl methylcellulose whose trade name is
- Metolose or Methocel is available with an apparent viscosity ranging from 4 to 100,000. In the preferred embodiment of the process, the grade 4000 centipoise is used.
- Kollidon SR consists mainly of polyvinyl acetate and povidone, its particle size is close to 100 ⁇ m and its apparent density varies from 0.3 g / ml to 0.45 g / ml. Lactose is used for its diluent properties, a compressible grade of lactose will preferably be used with a particle size of less than 200 ⁇ m.
- the excipients and active ingredient are mixed, preferably by inversion after sieving of each constituent.
- the mixing times are adjusted according to the quantity of product to be mixed and the apparent volume.
- the format of the tablet can be either round or oblong.
- the diameter must be large enough to obtain, after swelling, mechanical retention in the pylorus (diameter preferably greater than or equal to 10 mm).
- the compression force is adjusted so as to obtain a hardness of between 40 and 160 Newtons, and preferably close to 80 Newtons in order to obtain immediate flotation and a friability of less than 1%.
- the mass of the tablet is preferably close to 400 mg.
- the proportion of active principle and of the low density excipient is important since the lower the active principle / excipient ratio, the greater the buoyancy and the slower the kinetics of release.
- At least one disintegrating agent leads to an accelerated release of the active principle.
- Mention may be made, for such agents, of crosslinked polyvinylpirrolidone, hydroxypropylcellulose, crosslinked carboxymethylcellulose, hydroxypropylmethylcellulose, or also clays.
- the compression force can have an effect on the kinetics of release of the active principle since the density varies but this also decreases the buoyancy.
- increasing the compressive force does not change its release kinetics, which makes it the best embodiment.
- at least one retarding agent which slows down the release kinetics, these agents being directly associated with the active principle.
- Mention may be made of polyvinylpyrrolidone, gelatin, ethylcellulose, derivatives of polymethylmethacrylates and their aqueous dispersions as well as alginic acid and its salts.
- At least one hydrophilic diluent can be added simultaneously to the excipients in the external phase such as mannitol, lactose, starch, sorbitol, xylitol, microcrystalline cellulose, carbonates, soluble and insoluble hydrogen carbonates. These diluents have the property of accelerating the release of the active ingredient. Conversely, liposoluble diluents can on the contrary slow down the release of the active principle. At least one of these diluents can be chosen from palmitates, hydrogenated castor oil or glycerol monostearates. By their density, it improves the buoyancy and strengthens the gastric residence.
- agents may be useful for manufacturing and include lubricants such as talc, magnesium stearate, stearic acid, glycerol monostearate, polyethylene glycol derivatives, glycerol behenate as well as flow agents like colloidal silica.
- Tests have been carried out by varying the excipient composition for the same dose of active principle by supplementing with a hydrophilic diluent, the quantity of which is varied inversely proportional to the excipient.
- the formulations have been summarized with hydroxypropylmethylcellulose (HPMC) as an excipient, a constant hardness and in FIG. 2 the dissolution curve obtained. It is noted that in all cases, the flotation is immediate and that the percentage of excipient makes it possible to act on the dissolution profile. There is also a delayed release.
- the formulations have been summarized with Kollidon SR as an excipient, the composition of which is kept constant as well as that of the active principle by varying only the compressive force.
- Figure 4 shows the corresponding dissolution curve.
- the release is delayed but with the Kollidon SR, the compressive force modifies only very little the release profile of the active ingredient. There is independence of the hardness of the tablet when using the Kollidon SR.
- a tramadol salt is mixed by inversion at a dose of 100 mg / tablet and a hydroxypropylmethylcellulose derivative (marketed under the name Methocel 90SH) at 300 mg per tablet by direct compression with a sufficient compressive force to obtain a similar hardness of 80 Newtons.
- Methocel 90SH hydroxypropylmethylcellulose derivative
- a hard tablet with a total weight of 400 mg is obtained. Such a tablet immediately floats.
- a tramadol salt is mixed by inverting at a dose of 100 mg / tablet and a mixture of an excipient and an adjuvant.
- This mixture comprises a derivative of hydroxypropylmethylcellulose (marketed under the name Methocel 90SH) at 150 mg per tablet and lactose at 150 mg per tablet.
- the assembly is compressed by direct compression to obtain a 400 mg tablet whose hardness is close to 80 N. This form is immediately flotation.
- Tramadol salt is mixed by inverting at a dose of 100 mg / tablet and a mixture of 210 mg of HPMC (Methocel 90SH) and 90 mg of alginic acid. This mixture is compressed by direct compression so as to obtain a 400 mg tablet. Flotation is immediate.
- a mixture of tramadol is granulated with a 10% aqueous solution of polyvinylpyrrolidone K 90. This granulated mixture of active principle is passed through a 0.8 mm sieve.
- the granule is then mixed with a hydroxypropylmethylcellulose derivative as described in Example 1 to obtain a tablet with a final mass of 400 mg.
