Definitions

  • Present invention relates to tablet forms comprising cefixime. Said tablet forms are characterized by being in effervescent form.
  • Cefixime was first described in European patent no EP0030630 (Bl) and it is known with the chemical name of (6R,7R)-7- ⁇ [2-(2-amino-l,3-thiazol-4-yl)-2-
  • carboxylic acid (Formula 1). It is defined as a third generation cephalosporin and indicated for use in the treatment of infections caused by gram positive and gram negative bacteria.
  • Cefixime physically appears as white or light yellow crystal powder. It is freely soluble is methanol and propylene glycol, partially soluble in ethanol and acetone however it does not dissolve in ether, ethyl acetate, hexane and water. Its solubility in aqueous solutions changes with respect to the pH of the solution. Accordingly its solubility in a solution with a pH value of 3.2 is 0.5 mg/mL at room temperature; however when the pH of the solution is increased to 4.2 solubility increases to 18 mg/mL.
  • the product named as SUPRAX that is sold by Fujisawa/Astellas comprises cefixime as active agent and is present in oral tablet or oral suspension forms and in dosages comprising high amounts like 200 mg and 400 mg cefixime.
  • Tablets comprising 200 mg or 400 mg active agents become very big in size when formulated with excipients and this causes problems about use of these tablets for patients having difficulty in swallowing, especially for pediatric and geriatric patients.
  • Suspension forms that are developed to overcome these problems are undesirable since it is possible to take uncontrolled or high dose and in addition to that they have chemical and physical stability problems, have high manufacturing cost, and cause problems when used or when carried.
  • EP0281200 discloses fast dispersing tablets comprising microcrystalline cellulose, microfine cellulose or a mixture thereof in an amount of 24-70 %.
  • Inventors have surprisingly developed a tablet formulation that disperses in water without using cellulose based disintegrants.
  • Subject of the present invention is related to formulation of effervescent tablets and granules comprising cefixime and processes for preparation of these. Surprisingly it was found that effervescent tablets comprising cefixime, which has a low solubility, and formulated with the formulation given in the present invention dissolves in water and forms a homogenous cefixime solution.
  • first aspect of the invention is effervescent tablet and granule formulations comprising cefixime.
  • Second aspect of the invention is use of cefixime in an amount 1-60%, preferably in an amount 5-50% and more preferably in an amount 10-40% in effervescent tablet and granule formulation of the present invention.
  • Cefixime used in the invention can be in monohydrate, dihydrate, trihydrate and/or anhydrous form.
  • Another aspect of the invention is pharmaceutical composition comprising cefixime and in addition to that pharmaceutically acceptable excipients.
  • Said pharmaceutical composition is formulated for effervescent tablet and granule forms. Accordingly, another aspect of the invention relates to pharmaceutical compositions for oral application, comprising cefixime and pharmaceutically acceptable excipients such as effervescent couple, sweetener, binder, water soluble lubricant and flavoring agents and other pharmaceutically acceptable excipients.
  • cefixime and pharmaceutically acceptable excipients such as effervescent couple, sweetener, binder, water soluble lubricant and flavoring agents and other pharmaceutically acceptable excipients.
  • cefixime can be present in an amount of 1-60%
  • effervescent couple can be present in an amount of 10-90%
  • sweetener can be present in an amount of 0.1-5%
  • binder can be present in an amount of 0.1-10%
  • water soluble lubricant can be present in an amount of 0.1-5%
  • flavoring agent can be present in an amount of 0.1-5%.
  • Said effervescent couple can be selected from organic acids such as citric acid, tartaric acid, malic acid, fumaric acid etc., basic agents such as sodium hydrogen carbonate, sodium carbonate, potassium carbonate, potassium hydrogen carbonate etc.
  • Sweetener that can be used in the tablet and granule formulations of the present invention can be selected from a group comprising acesulfame, aspartam, fructose, maltitol, xylitol, saccharine, sodium cyclamate, sucralose, sucrose. Preferably aspartame is used.
  • Water soluble lubricant that can be used in the tablet and granule formulations of the present invention can be selected from a group comprising PEG6000 and sodium benzoate.
  • PEG6000 polyethylene glycol
  • 1-2000 mg of cefixime or its pharmaceutically acceptable salts, hydrates, solvates and/or a combination of these in an amount equivalent to 1-2000 mg cefixime can be used.
  • Binder that can be used in the tablet and granule formulations of the present invention can be selected from a group comprising; ethyl cellulose, gelatine, hypromellose, magnesium aluminium silicate, maltodextrin, polyethylene oxide and povidone.
  • the preferred binder is povidone. It was seen that in tablets in which cefixime :povidone ratio is 20:1, preferably 15:1 and most preferably 10:1 physical qualities such as friability and stability and chemical properties such as solubility and dispersibility have the desired characteristics and that the said ratio plays an important role in obtaining water soluble cefixime effervescent tablets and granules.
  • another aspect of the present invention is effervescent tablet formulations comprising cefixime and povidon in an amount such that cefixime:povidon ratio is 20:1, preferably 15:1 and more preferably 10:1.
  • Another aspect of the invention is use of the pharmaceutical compositions for the treatment of infections caused by gram positive and gram negative bacteria.
  • Another aspect of the invention is related to processes for use in the preparation of effervescent tablet and granules comprising cefixime. Said process comprises use of wet and/or dry granulation techniques present in the state of the art.
  • a process for the preparation of the effervescent tablet or granule according to the present invention comprises granulation of cefixime, effervescent couple, sweetener and binder with water or an aqueous solution, drying of the formed granules, mixing dried granules with flavoring agent and water soluble lubricant and optionally compressing the formed mixture in tablet pressing machine.
