Irradiation is an established method of sterilization for pharmaceutical products. Radiation sterilization can be achieved with gamma rays, electron beams, and X-rays. Each of these techniques has its advantages and disadvantages. The author describes these methods, the ways to find the correct sterilization doses, and the regulatory and safety concerns about irradation sterilization.

Aseptic processing has advanced over the past several decades, yet the pharmaceutical industry is still accepting of its limitations, particularly as it relates to human intervention as a source of contamination. The authors explain the importance of further diminishing the role of operators in aseptic processing and the approaches and technologies needed to achieve that goal.

The Truth about Interventions In Aseptic Processing

Interphex2007, New York, NY (Apr. 25)-As governments begin to contemplate the possibility of biological terrorism or a pandemic event, a new problem begins to emerge: in the case of a pandemic or an attack, even if a vaccine or treatment exists, how could it be produced in sufficient numbers to prevent the deaths of millions of people? That question was addressed in at the conference session, "Responding to Bioterrorism and Pandemic Events: A Case for Development of Flexible Manufacturing Space for Vaccine Production," at Interphex today.

Lyon, France (Apr. 17)-Sanofi Pasteur, the vaccine division of the Sanofi-Aventis Group, announced that the US Food and Drug Administration has licensed its H5N1 vaccine, making it the first avian-influenza vaccine for humans in the United States.

The authors prepared and tested press-coated tablets with various weight ratios of ethylcellulose to hydroxypropylcellulose (HPC) and various ratios of two different batches of HPC as an outer coating shell and fillers in core tablets. The tablets were examined for changes in time lag and release patterns of salbutamol sulfate.

Hydrogels are biocompatible drug delivery systems by which the physical properties can be controlled by the cross-linking density. Hydrogels were prepared by copolymerization of acrylic acid monomers in the presence of poly(ethylene glycol)(PEG) to form polyethylene diacrylate (PEDGA). Various molecular weights of PEGs were used for the synthesis of PEGDA to study the effect of molecular weight of PEG on the properties of hydrogels. These hydrogels were further characterized for free water, swelling behavior, water diffusion, drug loading, and drug release profile. By analyzing the swelling behavior and release pattern of the hydrogels, the authors show that these systems can be suitably used for controlled delivery of drugs.
