Definitions

  • This invention is concerned with a novel method of wet granulation in the manufacture of tablets comprising a large dose of a highly soluble compound as active ingredient.
  • the novel method comprises the addition of a second compound having the capability of decreasing solubility of the active ingredient prior to agglomeration.
  • the invention is particularly concerned with the novel method wherein the active ingredient is a highly soluble ionic compound.
  • the novel method of this invention is a wet granulation of an active ingredient which is a highly soluble compound and is to be inco ⁇ orated in a relatively high concentration in compressed tablets which comprises the addition of a second compound to reduce the solubility of the active ingredient prior to the agglomeration step.
  • the solubility of the active ingredient is decreased and a signficant increase in the viscosity of the granulation is adequately suppressed.
  • This novel method is particularly useful wherein the active ingredient is ionic and has an aqueous solubility of about 10 to about 500 mg/ml, especially about 135 to about 235 mg/ml of water.
  • the second compound added during the novel process is ordinarily a soluble ionic compound that can suppress the solubility of the active ingredient especially an electrolyte having an ion in common with that of the active ingredient.
  • the tablet compositions prepared by the novel method of this invention are generally art recognized and employ standard excipients based on their compatibility with one another and with the active ingredient .
  • excipients are such as: microcrystalline cellulose, dextrates, calcium phosphates, or pregelatinized starch for their compactibility properties, lactose, mannitol, sorbitol, xylitol, sucrose or glucose because of their water solubility which improves the agglomeration process; hydroxypropyl cellulose, hydroxypropyl methylcellulose, polyvinly pyrrolidone as binders or adhesives; Croscarmelose, crospovidone or sodium starch glycolate as disintegrants; and lastly, magnesium or calcium stearate, stearic acid, sodium stearyl fumarate, or polyethylene glycols as lubricants; and a granulating fluid such as water or ethanol: water mixtures.
  • the active agent is dry blended with the excipients, and an aqueous solution of the second compound is atomized onto the blend.
  • the blend is then granulated by spraying onto it an aqueous solution of the granulating fluid, which may or may not contain the binder. After drying, the granulation is sized, lubricated with magnesium stearate and then compressed to form the tablet cores.
  • the active ingredient in the following Example is identified as montelukast sodium. This name is listed in USAN and is used by T.R. Jones, et al in Can. J. Physiol. Pharmacol.. (1995) 73(2), 191-201. It has the name and absolute structural formula as follows:
  • Sodium chloride was dissolved in 540 g of water. Hydroxypropyl cellulose was dissolved in 1485 g of water. The microcrystalline cellulose, montelukast sodium, lactose hydrous and Croscarmellose were added together and blended for 5 minutes. The sodium chloride solution was added over 30 seconds and blended for 30 seconds. The hydroxypropylcellulose solution was sprayed onto the mixture over 1.5 minutes and mixed for 30 seconds. After drying, the granulation was sized and then lubricated by addition of the magnesium stearate. The lubricated blend was then compressed to form tablet cores.
