Description

DESCRIPTION PHARMACEUTICAL COMPOSITIONS OF MIRABEGRON FIELD OF INVENTION The present invention relates to a homogenous pharmaceutical composition comprising mirabegron or a pharmaceutically acceptable salt thereof developed in the prolonged release of the solid dosage form with improved pharmaceutical properties. BACKGROUND O F THE INVENTION Overactive bladder is a chronic distressing condition that has a tremendous impact on the health-related quality of life of the inflicted individuals (daily activities and social functions). According to the International Continence Society, the overactive bladder syndrome is characterized by urgency, with or without urinary incontinence, usually associated with increased daytime frequency and nocturia. Irrespective of the pathophysiology, the aim of the pharmacotherapeutic treatment options indicated for the overactive bladder is to obtain the reduced or suppressed intensity of involuntary detrusor contraction. There are many options for the treatment of overactive bladder such as; bladder training and drug therapy using antimuscarinic drugs. However, antimuscarinic drugs are not always effective in controlling an overactive bladder due to the adverse effects, including dry mouth, nausea, constipation, and central nervous system adverse effects, that cause poor long-term adherence to treatment. Then, a novel active substance mirabegron developed by Astellas Pharmac Inc. has been reported that this compound has not only both an activity of promoting insulin secretion and an activity of enhancing insulin sensitivity, but also an antiobestic activity and an antihyperlipemic activity based on an activity of selectively stimulating a β3 receptor, and is useful in treating diabetes. Further, it has been reported as an alternative option to antimuscarinic drugs for patients with overactive bladder accompanied by prostatic hyperplasia, or overactive bladder accompanied by urinary urgency, urinary incontinence, and urinary frequency. Mirabegron is an active substance that chemical name is 2-(2-Amino-1,3-thiazol-4-yl)-N-[4- (2-{[(2R)-2-hydroxy-2-phenylethyl] amino} ethyl) phenyl] acetamide with the following structure Formula I. The empirical formula is C21H24N4O2S. The compound has a molecular weight of 396.506 g/mol. Mirabegron appears as a white crystalline powder and is non-hygroscopic. It can be freely soluble in dimethyl sulfoxide, soluble in methanol, and soluble in water between neutral to acidic pH. Mirabegron has one chiral center and exhibits stereoisomerism. The manufacture of the finished product consists of the R-enantiomer. Mirabegron and its pharmaceutically acceptable salts thereof first have been described in EP1028111 numbered patent document by Yamanouchi Pharmaceutical Co. in which the preparation of mirabegron and its pharmaceutically acceptable salt thereof, with hydrochloride salt, in particular, Example 41 is also disclosed. Further, a patent document numbered EP1559427 was the first to disclose a pharmaceutical composition comprising mirabegron that could be used as a therapeutic agent for overactive bladders, such as overactive bladder accompanied by prostatic hyperplasia, or overactive bladder accompanied by urinary urgency, urinary incontinence, and urinary frequency. Moreover, the R-enantiomer used in the manufacture of the finished product was disclosed in EP2298752 numbered patent document. A finished product comprising mirabegron as an active substance was first approved in Japan and has been launched under the brand name BETANIS®. In a similar way, it was commercially approved by the U.S. Food&Drug Administration in June 2012 and by European Medicines Agency in December 2012 and has been launched under the brand name MYRBETRIQ® in the United States and BETMIGA® in Europe. All of the approved products are available in prolonged-release tablet dosage form in the strengths of 25 mg and 50 mg of mirabegron for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency, and urinary frequency. In the state of the art, there are many patents/patent applications, which are summarized below. EP2554168 relates to modified release pharmaceutical composition comprising mirabegron or a pharmaceutically acceptable salt thereof, and a carrier for a sustained release pharmaceutical composition, wherein the dissolution rate of the drug from the composition is 75% or less after 1.5 hours from the beginning of the dissolution test, and also wherein the pharmaceutical composition is not a sustained release hydrogel formulation which contains an additive that allows water to penetrate into the formulation, and a hydrogel-forming polymer. EP2345410 relates to modified release pharmaceutical composition comprising mirabegron, at least one additive having a solubility such that the volume of water required for dissolving 1 g of the additive is 10 mL or less to ensure penetration of water into the pharmaceutical composition, and a hydrogel-forming polymer having an average molecular weight of approximately 100.000 or more, or viscosity of 12 cP or more at a 5% aqueous solution at 25°C. WO2011122523 relates to a pharmaceutical composition comprising mirabegron or a pharmaceutically acceptable salt thereof, and a carrier for a sustained release pharmaceutical composition, and the drug dissolution rate after 30 minutes from the beginning of the dissolution test is less than 85%. EP3345600 relates to a pharmaceutical composition comprising mirabegron, hypromellose, and polyvinylpyrrolidone, wherein the spray-dried granulated product contains 100% or more by mass of the hypromellose, and the polyvinylpyrrolidone in total with respect to a content of the mirabegron. WO2019072404 relates to a pharmaceutical composition for modified release comprising mirabegron presenting 5-25 w/w% to the total weight of the uncoated tablet, polyethylene oxide having an average molecular weight of approximately 7,000,000 or viscosity of 7500 to 10000 cps at a 1% aqueous solution at 25°C and polyethylene glycol having an average molecular weight of approximately 6000 to 10000, preferably 8000, wherein the weight ratio polyethylene oxide to polyethylene glycol ranges from 1:3 to 1:4.5. EP3448366 relates to a pharmaceutical composition for modified release comprising; 5 to 25 w/w% mirabegron relative to the total weight of the formulation, 15 to 40 w%, relative to the total weightof the formulation, of a mixture of one or more polyethylene oxides having a viscosity of 100 to 800, preferably 400 to 800 cP at a 2% aqueous solution at 25°C, and a water- insoluble hydrophilic excipient. EP3554480 relates to a solid prolonged release solid pharmaceutical oral dosage form comprising mirabegron or a pharmaceutically acceptable salt thereof wherein mirabegron is distributed in a sustained release matrix comprising a hydrogel generator selected from the group consisting of a mixture of at least two different hydroxypropyl methylcellulose, of alginate, alginic acid, poly (meth) acrylate-based polymer and carrageenan, and wherein dissolution rate of the drug from the composition is 20% to 40% in 3 hours, 44% to 64% in 5 hours and more than 80% in 8.5 hours. WO2018169325 relates to a controlled-release pharmaceutical composition comprising mirabegron or a pharmaceutically acceptable salt thereof and a polyethylene oxide as a sustained-release agent. WO2022125007 relates to a prolonged release formulation comprising mirabegron or a pharmaceutically acceptable salt thereof as an active ingredient in which the release profile of the active ingredient is controlled by using a specific hydrophobic polymer and a plasticizer at a specific range of ratio between 1:0.5 to 1:1 in the coating formulation. From a pharmacokinetic point of view, the prolonged-release tablet dosage form comprising mirabegron leads to a slower absorption rate in the gastrointestinal tract than immediate-release formulations, even in fasted conditions, due to pharmacokinetic variation of mirabegron according to the presence or absence of food in the gastrointestinal tract. Besides that, it is reported that if it is administered with the high-fat meal there is a decrease in both Cmax and AUC by 45% and 17%, respectively in comparison with low-fat meals. Therefore, there is more than one problem in the prolonged-release formulation that should be overcome. In the improved formulation, a composition is designed to release active substance as prolonged-release and also to present promising pharmacokinetic properties with particular amounts of the matrix agents.
