The stability of neomycin in several pharmaceutical preparations*

Journal of the American Pharmaceutical Association (Scientific ed.), 1955
Neomycin is a water‐soluble polybasic antibiotic relatively stable in solution over a range of pH 2.0 to 9.0. It is most active in alkaline solution and is active against Gram‐positive and Gram‐negative bacteria, but is inactive against fungi. In ointment bases, i.

Crystalline Vitamin B12 in Pharmaceutical Preparations

Journal of the American Pharmaceutical Association (Scientific ed.), 1952
Abstract Some pharmaceutical properties of crystalline vitamin B 12 are reported. The anhydrous solid is hygroscopic and may absorb about 12 per cent of moisture. The solid presents no unusual stability problem in the hydrated form, and is also stable in dry triturations with mannitol, sodium chloride, and certain sugars.

The Polarographic Determination of Tenoxicam in the Pharmaceutical Preparations

Analytical Letters, 1996
Abstract In this study, the polarographic behaviour and the optimum polarographic conditions for the determination of TNX using DC (direct current), DP (differential pulse), SCAP (superimposed constant amplitude pulse) and SIAP (superimposed increasing amplitude pulse) polarographic techniques are described based on the reduction of enol group of the ...

Preparation of microspheres of water-soluble pharmaceuticals

Journal of Microencapsulation, 1989
An emulsion-solvent evaporation procedure involving the dispersion of an alcoholic solution of an active in liquid paraffin was used to prepare microspheres of water-soluble pharmaceuticals using ethylcellulose as a carrier. The effects of surfactant, plasticizer, drug loading, and agitation speed on drug release rate from the microspheres were ...

Biocatalysis Applied to the Preparation of Pharmaceuticals

Organic Process Research & Development, 2002
Biotransformations are now accepted as a methodology for the preparation of fine chemicals. The majority of enzyme-catalysed reactions involve the use of hydrolases, especially lipases, in hydrolysis, esterification or aminolysis reactions. Lyases, enzymes much less exploited in organic synthesis, are proving increasingly interesting, especially the ...
