The pharmaceutically acceptable polymer(s) are selected from the group comprising polyvinyl pyrrolidine, hydroxypropyl cellulose, hydroxypropylmethyl cellulose, methylcellulose, ethyl cellulose, polyvinyl pyrrolidone/polyvinyl acetate copolymers, polyethylene oxide polymers, acrylic acid polymers, methacrylic acid copolymers, natural gums, and derivatives and mixtures thereof.
Description
trade name "Biaxin XL". The literature sets out several approaches for therapeutic dosage forms that are designed to deliver the drug at a rate that allows it to reach the gastrointestinal tract. U.S. Patent No. 4,842,866 discloses the development of a controlled release formulation of erythromycin derivatives, wherein an alginate matrix comprising a water-soluble alginate and a complex salt of the alginic acid having a cation is used. which forms a soluble alginate salt and another cation which only forms an insoluble alginate salt. U.S. Patent No. 5,705,190, claims formulations in which a soluble alginate, a complex salt of alginic acid and an organic carboxylic acid are used. The patent discloses compositions containing equimolar amounts of citric acid and clarithromycin. U.S. Patents Nos. 6,010,718 and 6,551,616 disclose sustained release clarithromycin formulations containing 5 to 50% w / w of a pharmaceutically acceptable polymer. The specification and examples of this patent disclose preferred formulations containing 10% to 30% by weight of hydroxypropyl methylcellulose, a polymer for controlling speed, in addition to other excipients. This patent covers the prolonged release formulation of clarithromycin that is currently marketed under the trade name Biaxin XLm. The United States patent application
2003/0175341 discloses controlled release formulations containing about 0.1% to 4.5% of one or more cellulosic ether polymers that control the rate of release. PCT application WO 03/082241 discloses clarithromycin formulations that have better bioavailability when using the micronized active principle. The patent exemplifies clarithromycin prolonged release formulations in which the active ingredient has a particle size of less than 35 microns. The patent documents the improved relative dissolution with respect to the drug without micronising. However, the formulation as set forth in the patent does not show a significant improvement in bioavailability. U.S. Patent No. 4,389,393 discloses a sustained release composition that uses approximately less than one third of the weight of the solid unit dose of hydroxypropylmethylcellulose or a mixture of hydroxypropylmethylcellulose with some other rate-controlling polymers. In the specification of this patent, the inventors state that they have been able to achieve prolonged release from solid dosage forms containing approximately 5 to 30 weight percent of these hydroxypropylmethylcelluloses. All examples describe compositions containing 9% or more of the speed controlling polymer. Unexpectedly it has been found that compositions made with polymers that are used in a ratio ranging from about 50% to 65%, showed a pharmacokinetic profile similar to the innovative composition, which has lower polymer content.
OBJECTIVE OF THE INVENTION The object of the present invention is to provide a pharmaceutical composition for the prolonged release of erythromycin or its derivatives, which is administered once a day, this composition comprises approximately 50% to 65% by weight of pharmaceutically acceptable polymers. Another object of the invention is to provide a process for preparing a sustained release composition of erythromycin or its derivatives, which consists of mixing the active principle with about 50% to 65% by weight of one or more pharmaceutically acceptable polymers, granulating the mixture wet or dry and then deposit the granules in capsules or sachets or compress them to form tablets. Yet another objective of the present invention is to provide a pharmaceutical composition for the prolonged release of clarithromycin, comprising approximately 50% to 65% of pharmaceutically acceptable polymers, wherein the ratio T / R (time / rate or time / speed) of the geometric mean of Cmax and the ABC (area under the curve) are within an acceptable limit (80-125%) with respect to the current formulation of clarithromycin extended release marketed under the trade name Biaxin XL.
SUMMARY OF THE INVENTION In a basic aspect of the present invention, there is set forth a sustained release formulation of erythromycin or its own derivatives to be administered orally once a day, comprising approximately 50% to 65% by weight of pharmaceutically available polymers. acceptable or combinations thereof. In a preferred aspect of the invention there is disclosed a sustained release formulation of erythromycin or its derivatives, comprising erythromycin or its derivatives, pharmaceutically acceptable polymers in a proportion of about 50% to 65% by weight, in addition to other pharmaceutically acceptable excipients. The prolonged release formulation of the invention is prepared according to the wet or dry granulation processes and then depositing the granules in capsules or sachets or compressing them to form tablets.
