Definitions

  • the technical field of the invention relates to ibuprofen-containing soft gelatin capsules, pharmaceutical compositions of a substantially clear ibuprofen solution, and process for their manufacture.
  • Background of the Invention The insolubility of solid drug forms in common media such as water poses a major challenge because of the resulting low bioavailability of the active ingredients.
  • Liquid dosage forms in contrast, generally have better bioavailability.
  • Liquid compositions, and especially concentrated liquid pharmaceutical compositions offer many advantages over solid compositions. Liquids are easy to swallow and provide an excellent vehicle for the uniform delivery of pharmaceutical actives.
  • Liquids also provide a rapid onset of pharmacological action, since the composition does not first have to disintegrate and dissolve in the gastrointestinal tract.
  • Concentrated liquid compositions are ideally suited for encapsulation within a soft gelatin shell to provide a portable and easy-to-swallow soft, flexible capsule. Encapsulation also permits the accurate and uniform delivery of a unit dose of a pharmaceutical active ingredient, an advantage which becomes especially important when relatively small amounts of the active ingredient are to be delivered.
  • soft gelatin capsules are aesthetically appealing, especially when filled with a transparent liquid, and can be manufactured in a wide variety of sizes, shapes, and colors.
  • the dosage form is generally swallowed, it is unnecessary to flavor or otherwise mask any unpleasant taste of the active pharmaceutical ingredients.
  • U.S. Patent No. 5,484,606 describes the process for reducing the precipitation of difficult-to-solubilize pharmaceutical actives. The process uses propylene glycol to solubilize these actives along with polyethylene glycol and polyvinylpyrrolidine.
  • U.S. Patent No. 5,071,643 discloses a solvent system that is characterized as enhancing the solubility of pharmaceuticals for encapsulation. The system involves the use of gelling agents such as sodium stearate, sodium palmitate and calcium acetate to improve solubility of pharmaceutical ingredients into polyethylene glycol.
  • gelling agents such as sodium stearate, sodium palmitate and calcium acetate
  • 6,287,594 discloses oral liquid compositions which are characterized as having improved bioavailability.
  • the patent describes these compositions as being designed to provide drugs with minimal gastric irritability.
  • the ratio of active drug to polymer based dispersing agent is from about 1:1 to 1:50 w/w.
  • the resulting solution was found to be hazy.
  • U.S. Patent No. 6,387,400 discloses a process for improving concentration of a pharmaceutically active ingredient relative to fill composition. The process includes a two step process. In step one, a suspension of part of a drug is made in polyethylene glycol with a molecular weight of 200 daltons to 100,000 daltons and solubilizing it subsequently with hydroxide ion.
  • step two the remaining drug is added and the resulting suspension is solubilized by adding the remaining part of hydroxide ion.
  • the ratio of drug to fill material by weight is 1 :2 and/or 5:9.
  • U.S. Patent No. 5,919,481 discloses fill material for soft gelatin capsule that is translucent and semisolid in nature. The fill material uses cellulose ether and polyalkylene glycol with an average molecular weight of about 600 or less.
  • U.S. Patent No. 5,141,961 discloses a process for solubilizing difficult-to-solublize pharmaceutical actives. This process uses polyethylene glycol, polyvinylpyrrolidine and monohydric alcohols. The ratio of polyethylene glycol to polyvinylpynOlidine is about 2.5 to 1.

  • Hydrophobic therapeutic agents i.e., therapeutic compounds having poor solubility in aqueous solution, present problems in formulating such compounds for effective administration to patients.
  • a well-designed formulation must be capable of presenting a therapeutically effective amount of the hydrophobic compound to the desired absorption site, in an absorbable form. Even this minimal functionality may be difficult to achieve when delivery of the hydrophobic therapeutic agent requires interaction with aqueous physiological environments, such as gastric fluids and intestinal fluids.
  • compositions for delivery of such hydrophobic therapeutic agents must carry the hydrophobic compound through the aqueous environment while maintaining the hydrophobic compound in an absorbable form and avoiding the use of physiologically harmful solvents br excipients.
  • Soft gelatin capsules or softgels are predominantly used to contain liquids wherein the active ingredients are present in the dissolved or suspended state. Solutions also provide the best liquid form to obtain optimal "content uniformity" in softgel fill. In addition, a solution provides a faster and more uniform absorption of a pharmaceutical agent than a suspension. Because of these distinct technical advantages, solutions often are preferred over suspensions or other dispersions. However, an appropriate solution of the pharmaceutical agent cannot always be achieved.
  • the present invention provides clear and stable solutions of ibuprofen and the process of preparing them.
  • the term 'clear solutions' describes liquid pharmaceutical compositions that are transparent and free from turbidity or cloudiness or any other foreign particulate matter.

  • polyethylene glycols having a molecular weight range from about 400 to about 1000.
  • mixtures of two or more polyethylene glycols of different average molecular weight range can also be employed in the present invention.

However, in the present invention we have prepared clear solutions by employing less than 25% w/w of polyethylene glycol.
