Definitions
- the present invention relates to a pellet composition comprising propiverine or a pharmaceutically acceptable salt thereof for oral administration which is formulated as modified release.
- Overactive bladder (OAB) and the related condition of urge urinary incontinence represent the other major disorder of the storage function. They are characterized by a frequent need to void (frequency), with an intense urge to do so (urgency) and a need to void during the night (nocturia). Contrary to stress urinary incontinence, OAB and urge incontinence are not associated with urethral sphincter control but rather involves disturbances in bladder functions and the regulation thereof.
- antimuscarinic agents which exert their effects at muscarinic receptors and suppress or diminish the intensity of involuntary detrusor muscle contractions, are the first-choice pharmacotherapy for OAB, and may be the only therapy available whose efficacy is not in question.
- Propiverine hydrochloride is an extensively studied antimuscarinic and calcium channel blocker agent.
- Propiverine is one of the most frequently prescribed antimuscarinic drugs used for the treatment of overactive bladder and urinary incontinence.
- the chemical name of propiverine is (l-methyl-4-piperidyl diphenylpropoxyacetate) and it is a benzylic acid derivative as shown in Formula I.
- Formula I Propiverine is a BCS (Biopharmaceutical Classification System) Class III drug, which exhibits low permeability and high solubility.
- typical anticholinergic side effects like and accommodation disorders have to be accepted with a rapid increase in the blood level. Therefore, these side effects limit the amount of the possible unit dose of non-modified, rapidly releasing dosage forms to 10-20 mg.
- Propiverine in the form of its hydrochloride salt is currently marketed under the trade names Mictonorm® / Detrunorm®/ Proprinorm® by Apogepha Arzneistoff GmbH in two different dosage forms as immediate -release (IR) and modified-release (MR).
- IR immediate -release
- MR modified-release
- TR 2012/11270 patent application discloses an oral pharmaceutical composition comprising propiverine or a pharmaceutically acceptable salt thereof as an anticholinergic active agent.
- composition comprising propiverine or a pharmaceutically acceptable salt thereof which overcomes the above described problems in the prior art and has additive advantages over them.
- the main object of the present invention is to provide a composition comprising propiverine or a pharmaceutically acceptable salt thereof having high stability by the help of using a pellet composition.
- modified release refers to any pharmaceutical formulation that maintain constant levels of a drug in the patient's bloodstream by releasing the drug over an extended period of time. Modified release is formulated to release the active ingredient gradually and predictably over a 12-hour to 24-hour period.
- propiverine or a pharmaceutically acceptable salt thereof are thus not suitable for the realization of a modified release formulation.
- propiverine or a pharmaceutically acceptable salt thereof especially propiverine hydrochloride, is sensitive to environmental conditions and excipients used. Therefore, the steps and polymers employed to make modified-release are important in the present invention.
- Pellets can be blended to deliver incompatible active agents.
- the reproducibility of the pellet formulations is also much better than the reproducibility of the single-unit dosage forms. They are suitable systems for film coating with respect to the low surface area-volume ratios.
- one of the advantageous properties of the pellet formulations is being good resistance to external factors such as moisture, air and light.
- pellets have excellent flow properties. Considering all these advantages, the pellet form is best for use in propiverine-containing formulation.
- a pellet composition comprises propiverine or a pharmaceutically acceptable salt thereof, wherein the pellet composition is formulated as modified release.
- propiverine or a pharmaceutically acceptable salt thereof is propiverine hydrochloride.
- the amount of propiverine hydrochloride is present between 5.0% and 40.0%, 7.0% and 35.0%, 10.0% and 30.0%, 11.0% and 25.0%, 12.0% and 20.0%, 12.0% and 18.0% by weight of the pellet.
- propiverine hydrochloride is also present outside the pellet.
- the amount of propiverine hydrochloride is present between 1.0% and 30.0%, 1.0% and 25.0%, 1.0% and 20.0%, 1.0% and 15.0%, 1 .0% and 10.0%, 1.0% and 6.0% by weight of the total composition.
- the pellets further comprises at least one release modifying agent.
- Suitable release modifying agent is selected from the group comprising poly(methacrylic acid-co-methylmethacrylate), poly(methyl acrylate-co-methyl methacrylate-co-methacrylic acid), ethyl cellulose, methyl cellulose, hydroxypropylmethylcellulose, cellulose acetate, cellulose acetate phthalate, cellulose acetate trimellitate, hydroxypropyl methylcellulose phthalate, hydroxypropyl methylcellulose acetate succinate, poly(methacrylic acid-co- ethylacrylate), polyvinylchloride, polyvinyl acetate phthalate, poly(vinylpyrrolidone-co- vinylacetate), silicone elastomers, shellac, zein, rosin esters or mixtures thereof.
- the amount of the release modifying agent is between 1.0% and 25.0%, 2.0% and 20.0%, 3.0% and 15.0%, 5.0% and 10.0% by weight of the pellet.
- the amount of the release modifying agent is between 0.5% and 10.0%, 1.0% and 8.0%, 1.0% and 6.0%, 1.0% and 4.0% by weight of the total composition.
- the release modifying agent is poly(methacrylic acid-co-methylmethacrylate) 1 :2 (Eudragit S 100) or poly(methacrylic acid-co- methylmethacrylate) 1 :1 (Eudragit L 100) or poly(methyl acrylate-co-methyl methacrylate-co- methacrylic acid) 7:3:1 (Eudragit FS 30 D) , they can be used together or separately.
- the optimum amounts of the excipients for example the composition of the corresponding mixtures depend on several factors, like for example the desired retarding effect, the kind of the release modifying agent having their specific solubility and permeability, and the ratio of acidic substance to active agent propiverine. These parameters vary completely independently from each other and are of essential importance for the controlled and long- lasting, modified release of the propiverine.
- the preferred dosage forms are tablets or capsules filled with pellets as these are more convenient and easier to administer.
- the form of the composition is a tablet.
- Pellet is located within a tablet.
- the tablet further comprises at least one pharmaceutically acceptable excipient which is selected from the group comprising fillers, pH adjusters, binders, disintegrants, plasticizers, lubricants, glidants, suspending agents, permeability enhancing agents or mixtures thereof.

- the filler is neutral microcrystalline cellulose pellets or lactose or microcrystalline cellulose or mixtures thereof.
- fillers should be as inert as possible to prevent them from interacting with propiverine hydrochloride, they should serve only as a carrier to enable propiverine hydrochloride.
- neutral microcrystalline cellulose pellets support the formulation, such as by improving propiverine hydrochloride solubility, improving dissolution and enhancing stability. So, neutral microcrystalline cellulose pellets are used in pellets as fillers.
- compositions comprise at least one pharmaceutically acceptable organic or inorganic acid having a pKa value of less than 6.65.
