Patent number: 5888544Abstract: The effervescent system for effervescent tablets and/or effervescent granules contains, on the one hand, particles of a solid, edible, organic acid and, on the other hand, particles of at least one alkali metal bicarbonate, of which at least 1, preferably from 2 to 4, but at most 10, preferably at most 8, % by weight are superficially converted into dry alkali metal carbonate free of water of crystallization. The acid particles, preferably citric acid particles, can be covered in a manner known per se by partial reaction with at least one carbonate and/or bicarbonate, preferably from about 20 to 40% by weight thereof. The conversion mentioned is carried out by a procedure in which commercial alkali metal bicarbonate particles are heated in a vacuum vessel at less than 40, preferably less than 20, in particular less than 10, mbar at above 60.degree. C., preferably between 80.degree. C. and 120.degree. C., in particular at about 100.degree. C., and are cooled to below 60.degree. C., preferably to below 50.Type: GrantFiled: June 2, 1997Date of Patent: March 30, 1999Assignee: Gerhard GergelyInventors: Gerhard Gergely, Irmgard Gergely, Thomas Gergely, Stefan Gergely

Patent number: 5861141Abstract: Pharmaceutical formulations of cefaclor, suitable for the direct-compression manufacture of dispersible tablets, containing the antibiotic cefaclor in an amount between 35% and 50% by weight of the total weight of the formulation, along with suitable excipients and coadjuvants selected from disintegrators, diluents, lubricants, antiadherents, sweeteners, fragrances and, optionally, flavorings, opacifiers and colorants. Said formulations are suitable for the manufacture of dispersible tablets which disintegrate in less than three minutes in water at 19.degree.-21.degree. C., and are suitable for the treatment of infections caused by bacteria strains sensitive to cefaclor.Type: GrantFiled: October 13, 1995Date of Patent: January 19, 1999Assignee: Lilly S.A.Inventor: Flavia Arce Mendizabal
