Definitions

  • the present invention relates to the field of formulations of pharmaceutical compositions; in particular it relates to tablets of the MUPS type for oral administration of esomeprazole, and the method of preparation thereof.
  • Esomeprazole belongs to the class of proton pump inhibitors (PPI): drugs containing active ingredients discovered relatively recently, which have proved very effective in treating various gastrointestinal pathologies by reducing the acid secretion of the stomach.
  • PPI proton pump inhibitors
  • the enteric-coated tablets obtained by the conventional technique have long residence times in the stomach, sometimes unpredictable: there is an increased risk of degradation of the active ingredient, due to the residence time in the stomach and to microinfiltrations in the enteric coating.
  • the residence time in the stomach is short because the tablets or capsules disintegrate, releasing enteric-coated pellets having a diameter in the range 0.5-2.0 mm, which therefore pass through the stomach without stopping.
  • MUPS Multi Unit Pellet System
  • WO96/01623 describes tablets of the MUPS type, containing esomeprazole, in which, to avoid the aforementioned problems of compression, the pellets were coated with an enteric coating that contains a plasticizer in amounts from 20 to 50 wt.%, relative to the weight of the enteric coating.
  • a plasticizer in amounts from 20 to 50 wt.%, relative to the weight of the enteric coating.
  • the cores are isolated by applying neutral polymers characterized by low solubility owing to their high viscosity: it is therefore necessary to use dilute solutions, leading to lengthening of the covering times, made worse by the actual adhesiveness of the film.
  • concentrations used must be between 2 and 5% otherwise the viscosity becomes so great that spraying of the solutions is not possible.
  • the present invention thus solves the aforementioned problem by means of a method for preparation of tablets of the MUPS (Multi Unit Pellet System) type comprising esomeprazole, said method comprising the following steps:
  • step (iii) preparation of a mixture comprising enteric microgranules obtained from step (i) and the wet granulate obtained from step (ii);
  • step (iv) compression of the mixture obtained from step (iii) with a compression force equal to 1 .8-2.5 kN with lubricated punches.
  • the granulated excipients are mixed, wet as obtained without prior drying, with the enteric-coated pellets previously produced.
  • What distinguishes the present invention from other pharmaceutical formulations of the MUPS type containing esomeprazole magnesium dihydrate already on the market is the use of a much lower compression force, so that the enteric coating of the pellets is not damaged during compression.
  • the tablets obtained disintegrate when in contact with the fluids and release the protected granules that they contain.
  • the presence of a water content of approx. 10% in the wet granulate of tableting excipients surprisingly makes it possible to obtain tablets having high hardness and low friability while applying a minimal compression force equal to approx. 2kN.
  • the tablets obtained by the aforementioned method have suitable hardness (above 15kp) and friability for withstanding the usual subsequent steps of film coating and packaging.
  • the tablets can then be coated with ordinary excipients for film coating in an aqueous medium.
  • the tablets lose the water added in the step of granulation of the tableting excipients.
  • the finished tablets thus produced display, surprisingly, a further increase in hardness at the end of the film coating cycle.
  • the present invention also relates to enteric microgranules containing esomeprazole that are particularly simple and convenient to be prepared and which, even if they do not possess particularly high mechanical strength and must not be submitted to high pressures during compression, can be used particularly advantageously in the aforementioned method; said microgranules each comprising:
  • microgranules preferably having an average diameter between 500 and 800 ⁇ ;
  • said layer (b) containing esomeprazole does not contain alkaline substances
  • said coating layer (d) can also contain plasticizers but in amounts such as not to endow said coating with sufficient mechanical strength to preserve enteric characteristics during dry compression.
  • the isolating layer (c) constituted of mannitol, applied simply in aqueous solution, makes it possible to obtain pellets with very fast production times and with excellent results. With the same operating conditions with respect to the neutral polymers used in the aforementioned patents, there is an approximately five-fold decrease in production times.
  • microgranules can be used, as well as for preparation of tablets of the MUPS type according to the method of the present invention, for the preparation of capsules filled with said microgranules.
  • tablette excipients means the inert additives, known and mentioned in the various pharmacopoeias, which are generally added to active ingredients, or to granules containing them, to facilitate their compression to tablets; in particular, for preparation of tablets of the MUPS type, disintegrating tableting excipients are used, for example microcrystalline cellulose, carboxymethyl starch, croscarmellose, crospovidone, pregelatinized starch and others.
  • the esomeprazole is esomeprazole magnesium dihydrate.
  • the pellets according to the present invention have an average diameter between 500 and 800 ⁇ .
  • the pellets according to the invention are prepared by fluidized bed technology.
  • the layer containing the active ingredient further comprises usual excipients, preferably polysorbate, povidone or PEG and mixtures thereof.
  • the layer of active ingredient does not comprise alkalizing substances.
  • the layer containing the active ingredient is applied on the inert (neutral) cores using an aqueous suspension of the components of the layer in which the active ingredient is contained at 15-25 wt.%, more preferably at approx. 20%.
  • the active ingredient is contained in larger amounts than is known in the prior art, in which suspensions are used at 6-10 wt.% of active ingredient. It has now been discovered that it is also possible to work with higher concentrations (up to 15- 25 wt.%) when said aqueous suspension is prepared and maintained at a temperature not above 20 °C, preferably between 10 and 20 °C; in fact, by carrying out homogenization of the suspension at this temperature, it is possible to prevent gelation thereof and make the spraying operation possible.
  • the isolating layer of mannitol is preferably applied by means of fluidized bed technology using a solution of mannitol in water preferably at a concentration by weight below 50%, more preferably at 10-30%.
  • Said solution of mannitol is preferably at pH 9-10, said pH preferably being obtained by adding a 1 N solution of NaOH.
  • the pellets according to the invention are made resistant to the gastric environment using suitable films for this purpose, known and referred to in the various pharmacopoeias; among these, preferably the following can be used: Eudragit L100- 55, hydroxypropylmethylcellulose phthalate, hydroxypropylmethylcellulose acetate, cellulose acetate phthalate, hydroxypropylmethylcellulose succinate, polyvinyl acetate.
  • the enteric coating can further comprise other usual excipients, for example glyceryl monostearate, triethyl citrate, talc, paraffin and mixtures thereof.
  • any plasticizers present are in amounts below 25 wt.% relative to the enteric polymers. The aforementioned amount of plasticizer is not sufficient to endow the pellets with the necessary mechanical strength in dry compression. The pellets are preserved, however, when compressed with wet granulate of tableting excipients according to the method of the present invention.
  • the pellets according to the invention or others selected for example from those known in the prior art are mixed with the tableting excipients and then compressed. It is convenient for the purposes of the present method to use the microgranules according to the present invention because they are easier to prepare while maintaining the desired enteric characteristics and release at neutral or slightly alkaline pH.
  • the granulate of the tableting excipients comprises cellulose and preferably further comprises an alditol of general formula H[CH(OH)] n H where n is between 5 and 12.
  • Said tableting excipients are advantageously constituted of cellulose or of mixtures of cellulose and an alditol of general formula H[CH(OH)] n H where n is between 5 and 12, preferably selected from mannitol, lactitol, isomalt, maltitol, sorbitol or xylitol.
  • the aforementioned mixture of cellulose+alditol preferably comprises 70-90 wt.% of cellulose and the remaining 10-30% of alditol.
  • the aforementioned cellulose+alditol mixture is preferably obtained by co-spray drying.
  • the tableting excipients are granulated with addition of water, to obtain a wet granulate with a water content preferably of 7-13%, more preferably 9-1 1 % (based on the weight of the excipients).
  • the water content was evaluated by testing for weight loss on drying.
  • the water used for preparation of the granulate of tableting excipients is preferably acidified beforehand to pH 3-5, preferably using hydrochloric acid.
  • the wet granulate is mixed with the enteric-coated pellets previously produced without carrying out drying.
  • the mixture thus obtained is compressed using conventional tableting presses, equipped for obtaining tablets of the desired shape and dosage.
  • the punches must be lubricated at the time of compression.
  • a tableting machine equipped with automatic distribution of a lubricant is used.
  • the lubricant is preferably selected from sodium stearyl fumarate, stearic acid, magnesium stearate, talc, purified silica, kaolin.
  • the amount of lubricant to use for lubricating the punches is preferably 0.2-3.0 wt.% relative to the total of the tableting mixture.
  • the enteric-coated pellets are mixed with the wet granulate of tableting excipients in the presence of a lubricant as well, which preferably is the same as is used for lubricating the punches.
  • a lubricant as well, which preferably is the same as is used for lubricating the punches.
