Benzocaine Determination in Pharmaceutical Preparations
Analytical Letters, 1982Abstract A new sensitive method for rapid and accurate determination of benzocaine via hydroxamic acid formation is described. The solution of hydroxylamine hydrochloride is reacted with benzocaine in alkaline medium to give corresponding hydroxamic acid (II) which forms the purple coloured complex with FeCl3 in acidic medium, having a maximum ...

Transgenic Rabbits to Prepare Pharmaceutical Proteins
2009The preparation of recombinant pharmaceutical proteins is one of the major challenges of biotechnology. Mammalian cells are required for a number of proteins which must be modified posttranscriptionally. Animal cell lines cultured in fermentors are presently the major source of complex proteins.

The stability of neomycin in several pharmaceutical preparations*
Journal of the American Pharmaceutical Association (Scientific ed.), 1955Neomycin 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.), 1952Abstract 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.

Preparation of microspheres of water-soluble pharmaceuticals
Journal of Microencapsulation, 1989An 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 ...
