Definitions

  • the present invention relates to stable olanzapine tablets and the process for its preparation; wherein the said tablets are stable to color, chemical degradation and polymorphic changes.
  • the chemical name of olanzapine is 2-methyl-4-(4-methyl-l- piperazinyl)-10H-thieno [2, 3-6] [15] benzodiazepine.
  • Olanzapine is an antagonist of 15 dopamine at D-I and D-2 receptors and. in addition, it has antimuscarinic, anticholinergic properties and antagonist activities at 5HT-2 receptor sites, with antagonist activity at noradrenergic ⁇ - receptors. The compound is useful in treating psychotic conditions such as schizophrenia, acute mania and mild anxiety states.
  • European Patent Number 454436B1 discloses pharmaceutical composition of olanzapine using conventional techniques.
  • the active ingredient is mixed with a carrier such as lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, 25 calcium phosphate, alignates, tragacanth, gelatin, syrup, methyl cellulose, microcrystalline cellulose, methyl and propyl- hydroxy benzoate, povidone, talc, aluminum stearate, magnesium stearate or mineral oil and converted to a suitable pharmaceutical composition.
  • a carrier such as lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, 25 calcium phosphate, alignates, tragacanth, gelatin, syrup, methyl cellulose, microcrystalline cellulose, methyl and propyl- hydroxy benzoate, povidone, talc, aluminum stearate, magnesium stearate or mineral oil and converted to
  • Coated formulations of olanzapine are also prepared in European Patent Publication Number 1231903 assigned to M/S Biochemie and PCT publication 2005009407.
  • Coated and uncoated formulation of olanzapine is known in the art as techniques like wet granulaton are not suitable due to problems of stability.
  • Direct compression is widely used for moderate dose active (API) as a process of choice. It involves simple mixing of active with other excipients followed by compression to tablets. However, the tablets produced by DC may possess problems of poor content uniformity. Taste masking and chemical compatability are often compromised as active is present as primary particles and completely exposed to saliva of oral cavity and also to all the excipients of tablet.
  • Lyophilised tablets e,g, Zyprexa Velotab are produced by a complex, time intensive and costly process involving freeze drying of suspension of drug/ excipients in preformed blister. This requires a dedicated facility.
  • Coating of active with tastemasking polymers is also conventionally used to improve taste and stability characteristics of API, however it is a critical and lengthy process and the taste masked granules often provide grittiness, roughness and poor content uniformity problems.
  • the object of the invention is to provide stable olanzapine tablets.
  • the tablets of the present invention are without coating.
  • the tablets are stable to color, chemical degradation and polymorphic changes for 3 months at 40 0 C / 75% relative humidity in open vials.
  • Also provided herewith is a simple process for the preparation of stable olanzapine tablets.
  • olanzapine e.g.calcium carbonate, microcrystalline cellulose
  • Taste masking can be achieved by compaction with saliva insoluble fillers which have good solubility or swellability in GIT fluids.
  • Stable olanzapine tablets comprising compacted blend of olanzapine and at least one pharmaceutical excipient; mixed with extragranular blend of diluent(s), disintegrant(s), lubricant(s) and optional sweetener(s); wherein the said tablets are stable to color, chemical degradation and polymorphic changes for 3 months at 40 0 C / 75% relative humidity in open vials.
  • the tablets of the present invention can be prepared by a simple process such as compaction of granules with olanzapine with at least one pharmaceutical excipient.
  • the stable olanzapine tablets prepared according to one embodiment of the present invention are stable to color, chemical degradation and polymorphic changes for 3 months at 40 0 C / 75% relative humidity in open vials.
  • stable as used herein is intended to encompass stability with respect to color, chemical degradation and polymorphic changes.
  • the chemical degradation impurity is ⁇ 0.5% by HPLC.
  • the formulations of the present invention may contain anhydrous fo ⁇ ns of olanzapine, which are disclosed e.g. in European Patent Number 733635 Bl , therein designated as Form I and Form II; in United States Patent Number 6,348,458, therein designated as Form III, Form IV, Form V; in United States Patent Number 2002/086993 Al, therein designated as form X. Also useful are hydrates of olanzapine which are disclosed e.g. in European Patent Number 0831098 Bl, therein designated as forms B, D, E; in PCT publication Number 02/18390A, therein designated as monohydrate I and dihydrate I.
  • a process for the preparation of stable olanzapine tablets comprises compaction, miling, mixing and compression.
  • Olanzapine tablets prepared by process comprising compacting olanzapine with atleast one pharmaceutical excipient, milling and mixing with extragranular blend of pharmaceutical excipients selected from diluents(s), lubricant(s), disintegrant(s), optional sweetener(s) are stable to color, chemical degradation and polymorphic changes for atleast 3 months at 40 0 C / 75% relative humidity in open vials.
  • Compaction of olanzapine and at least one pharmaceutical excipient is a key step in the process of the present invention.
  • Olanzapine is effective over a wide dosage range, the actual dose administered depending on the condition treated. For example, in the treatment of adult humans, dosages of from 0.25 to 50 mg per day may be used. A once-daily dosage is normally sufficient, although divided doses may be administered. Preferred tablets of the invention thus comprise 0.25 to 50 mg of olanzapine. The preferred weight of the tablets is 50 to 1000 mg,
  • the pharmaceutical excipient may be selected from directly compressible calcium carbonate, dibasic calcium phosphate, microcrystalline cellulose tribasic calcium phosphate, celluloses, cellulose based polymers, starches and the like.
  • the ratio of olanzapine to pharmaceutical excipient may be in the range of 1 : 1 to 1 : 10.
  • Calcium carbonate when included in orally- administered solid pharmaceutical products, such as tablets, the tablets readily disintegrates in the mouth, and thus eliminates the need for swallowing the tablets in order to release the active pharmaceutical ingredient. It accelerates rapid disintegration of the tablets when the tablets contacts water and is used in conjunction with a super disintegrant.
  • the compacts of olanzapine and at least one pharmaceutical excipient obtained on compaction may be subjected to milling.
  • Granules obtained may have an average diameter of less than microns.
  • the granules may be mixed with extragranular blend comprising pharmaceutical excipients such as diluent(s), lubricant(s), disintegrate(s), binder(s), flavoring agent(s), coloring agent(s), stabilizer(s), surfactant(s), glidant(s), plasticizer(s), preservative(s) and sweetener(s).
