Abstract: A filled cellulose capsule for oral administration, wherein the capsule comprises a cellulose derivative as the base and the filling comprises a therapeutically effective amount of a benzimidazole derivative but does not comprise a lower-substituted hydroxypropyl cellulose (13 to 16% hydroxypropoxy groups) is disclosed.

Abstract: Non-crystalline, in particular amorphous, pharmaceutically acceptable atorvastatin salts, especially the calcium salt, are prepared from atorvastatin lactone or from a compound of formula (I) where A denotes a common protecting group or separate protecting groups for the two hydroxy groups, and B denotes a carboxylic acid protecting group, without the need of prior formation of atorvastatin lactone, the crystalline form of the atorvastatin salt, or a mixture of amorphous and crystalline forms of the atorvastatin salt. Pharmaceutical formulations are prepared from these salts.

Abstract: A process for the isolation of clavulanic acid and pharmaceutically acceptable salts thereof, such as potassium clavulanate, from the aqueous fermentation broth of a clavulanic acid-producing microorganism comprises the microfiltration of the broth without prior treatment.

Abstract: Provided is a process for preparation and/or purification of clavulanic acid or a pharmaceutically acceptable salt or ester thereof including removing solids from a clavulanic acid containing fermentation broth by microfiltration to form a first filtrate, further removing solids from the first filtrate by ultrafiltration to form a second filtrate, concentrating the second filtrate by removal of water, and treating the concentrated second filtrate to isolate clavulanic acid or a pharmaceutically acceptable salt or ester thereof.

Abstract: Provided is a process for preparation of pharmaceutically acceptable metal salts of clavulanic acid which avoids the use of toxic amines or other intermediates. The process involves removing solids from a clavulanic acid containing fermentation broth by microfiltration; acidifying the microfiltrate to a pH of between 1 and 3; extracting the acidified microfiltrate with a water immiscible solvent and separating the clavulanic acid containing extract; without converting the clavulanic acid containing extract to an intermediate clavulanate salt, mixing the extract with a metal donor and at least one additional non-aqueous solvent; and separating a pharmaceutically acceptable metal clavulanate salt from the solution.
