Definitions
- the present invention relates to an improved extended release dosage form, and in particular to a pharmaceutical composition for oral administration comprising a therapeutically effective quantity of fesoterodine or a pharmaceutically acceptable salt, metabolite, or derivative thereof, as an active ingredient, and an effective quantity of ion exchange resin in order to prevent the degradation of said active ingredient, and a process for the preparation thereof.
- Fesoterodine is a muscarinic receptor antagonist used for the treatment of overactive bladder syndrome including urinary incontinence.
- Fesoterodine' s chemical name is [2-[(lR)-3- (Di(propan-2-yl)amino)-l -phenylpropyl]-4-(hydroxymethyl)phenyl]2-methylpropanoate) and its chemical structure is presented by the following Formula I.
- Fesoterodine is rapidly hydrolyzed in vivo into its active metabolite 5-hydroxy methyl tolterodine, which binds and inhibits muscarinic receptors on the bladder detrusor muscle, thereby preventing bladder contractions or spasms caused by acetylcholine. This results in the relaxation of bladder smooth muscle and greater bladder capacity, in addition to a reduction in involuntary muscle contractions and involuntary loss of urine.
- the dissolution profile of extended release pharmaceutical compositions containing fesoterodine or a pharmaceutical acceptable salt, derivative and metabolite thereof can also be influenced by the selection of the excipients, as the drug release rate is dependent from the gastrointestinal pH-value and/or ionic strength. It is favorable for an extended release formulation to possess drug release rates, independent or less dependent from the ionic strength and/or pH of the environment through out the whole gastrointestinal tract in order to achieve better treatment to a patient.
- EP-B-2029134 discloses a pharmaceutical granulate comprising fesoterodine or a pharmaceutically acceptable salt or solvate thereof and a pharmaceutically acceptable stabilizer against hydrolysis, such as sorbitol, xylitol, polydextrose, isomalt, dextrose or combinations thereof. Further, said fesoterodine and stabilizer granulate is embedded in a gel matrix formed by a water swellable sustained release agent such as hydroxypropyl methylcellulose. According to said document, fesoterodine is more stable in a composition comprising sugar alcohols and in the presence of water e.g. by wet granulation. Dry granulation or direct compression resulted in higher amounts of undesirable degradation products.
- EP-A-2508175 discloses a microencapsulated fesoterodine composition which is composed of a particle containing fesoterodine and a shell surrounding the fesoterodine-containing particle, wherein the shell comprises a hydrophobic polymer as rate-controlling agent, such as acrylate- based polymers, acrylates or methylacrylates and a pore-forming agent, such as water soluble polymer or water soluble salt.
- the proposed composition requires a complex-structured pharmaceutical composition.
- an object of the present invention to provide an improved sustained release solid dosage composition for oral administration containing fesoterodine or pharmaceutical acceptable salt, derivative and metabolite thereof as an active ingredient, which overcomes the deficiencies of the prior art.
- an extended release pharmaceutical composition for oral administration comprising a therapeutically effective quantity of fesoterodine or a pharmaceutically acceptable salt, metabolite or derivative thereof, as an active ingredient and an effective quantity of ion exchange resin as a stabilizer in order to prevent the degradation and improve the physicochemical stability of the active ingredient in the finished dosage form.
- a process for the preparation of an extended release pharmaceutical composition for oral administration comprising a therapeutically effective quantity of fesoterodine or a pharmaceutically acceptable salt, metabolite or derivative thereof as an active ingredient, and an effective quantity of ion exchange resin as a stabilizer in order to prevent the degradation of said active ingredient is provided, wherein said process comprises following steps:
- a) Complexation Dissolving the total quantity of fesoterodine or a pharmaceutically acceptable salt, metabolite or derivative thereof into an appropriate solvent and forming a homogenous mixture by adding the total quantity of an ion exchange resin and mixing for appropriate time until the complexation reaction is completed, and subsequently separating the solid fraction (resinate) from prepared slurry by discarding the filtrate;
- step d) Adding to the sieved resinate from step c) the total quantity of a rate controlling agent and at least one optional additional excipient such as binder, diluent, lubricant and/or glidant and mixing for appropriate time.
- a rate controlling agent such as binder, diluent, lubricant and/or glidant and mixing for appropriate time.
- step e) Compressing the final blend from step d) into a desired tablet form in a rotary compression machine using appropriate punches.
- Fig. 1 shows dissolution profiles of fesoterodine containing pharmaceutical composition according to the present invention (composition 1) DETAILED DESCRIPTION OF THE INVENTION
- a pharmaceutical composition comprising fesoterodine or salts, metabolites or derivatives thereof is considered to be “stable” if said ingredient degradates less or more slowly than it does on its own and/or in known pharmaceutical compositions during storage.
- excipient is considered to be "incompatible” with fesoterodine or salts, metabolites or derivatives thereof if it promotes the degradation of said active ingredient, that is to say, if said active ingredient degrades more or faster in the presence of said excipient when compared with the degradation of said active ingredient on its own.
- incompatibility is defined accordingly.
- the active ingredient contained in a dosage form is "bioavailable", if when administered in a dosage form is released from the dosage form, absorbed and reaches, at least the same, concentration levels in plasma as any of the marketed products containing the same quantity of the same active ingredient and intended for the same use.
- the pharmaceutical composition may be in various forms, the preferred solid forms are tablets, capsules and caplets.
- the object of the present invention is achieved by employing an ion exchange resin such as Sodium Polysterene Sulfonate, in order to prevent the degradation and improve the physicochemical stability of the active ingredient in the finished dosage form.
- an ion exchange resin such as Sodium Polysterene Sulfonate
- Ion exchange resins are insoluble polymers that contain acidic or basic functional groups and have the ability to exchange counter-ions within aqueous solutions surrounding them.
- the efficacy of ion exchange resins mainly depends upon their physical properties such as degree of cross-linking, porosity, acid base strength, stability, purity and particle size.
- the most common resins used in pharmaceutical formulations are cross-linked polystyrene and polymethacrylate polymers.
- the use of ion exchange resins into drug delivery systems have been encouraged because of the their physico-chemical stability, inert nature, uniform size, spherical shape assisting coating and equilibrium driven reproducible drug release in ionic environment.
- the physical and chemical properties of the ion exchange resins will release the drug more uniformly than that of simple matrix formulations.
- Complexes between ion exchange resins and drugs are known as resinates, which have been used in pharmaceutical formulations for several decades.
- Resinates are usually prepared by mixing the resin with a drug solution and allowing sufficient time for loading. The resin/fluid slurry is then filtered and the filtrate washed. The resinate is then dried. The dried resinate will be free of flowing powder with physical properties similar to the original resin, which can be formulated into tablets, capsules, lozenges etc.
