The possibility that the virus arrives in other parts of the world is real as for all the types of influence virus. In order that a strain has a wide distribution, its antigenic characteristics must ensure that it escapes the neutralization of antibodies of the host and of the surrounding population.

~Oxcarbazepine is in a class of drug called anticonvulsants. It inhibits unusual electrical activity in the brain. Oxcarbazepine may help control seizures, but it does not cure the disease. However, this medication is also used for treatment of epilepsy. Oxcarbazepine HPLC chromatography determination method was developed to quantify the quality of the synthesized drug. The developed method was then validated for the determination of Oxcarbazepine The separation was achieved in a octylsilyl s...

~~The term ‘5 – batch analysis’ originates from the US EPA guidelines for testing of pesticides. The term is accepted now by most regulatory bodies like EEC, Indian registration authorities namely CIB & RC and other countries as well. There are no guidelines of OECD for this study. The study is essential to determine the composition of the product with respect to the active ingredient and its associated impurities.

Industrial process for OXICONAZOLE Dr Krishnasarma PathyOxiconazole inhibits ergosterol biosynthesis, which is required forcytoplasmic membrane integrity of fungi. It acts to destabilize the fungal cyctochromeP450 51 enzyme (also known as Lanosterol 14-alpha demethylase). This is vital in thecell membrance structure of the fungus. Its inhibition leads to cell lysis. Oxiconazole hasalso been shown in inhibit DNA synthesis and suppress intracellular concentrations ofATP. Like other imidazole an...

Process for the preparation of enantioselective method of making methylphenidate and derivatives . The method involves use of a rhodium catalyst, and selectively produces the D-enantiomer of the methylphenidate derivative in excess of the L-enantiomer . Furthermore, the method selectively produces the threo-diastereomer in excess of the erythro-diastereomer. The method is thus suitable for synthesis of D-threo-methylphenidate (the biologically active form of this compound) and derivatives &...

The N-acetyl derivative of β-phenethylamine is reacted with chlorosulfonic acid to form the para sulfonyl chloride derivative. This is then subjected to ammonolysis, followed by base-catalyzed removal of the acetamide. This is then acylated with 2-methoxy-5-chlorobenzoic acid chloride to give the amide intermediate. This is then reacted with cyclohexyl isocyanate to yield the sulfonylurea glibenclamide

Impurities are normally generated during the formation of Active PharmaceuticalIngredients and their intermediates. Chances of their generation during Drug Productsformation are less as formulation is a physical blending process. Care is taken that theseexcipients do not react with each other to produce the degradants. They may consist oforganic and inorganic, and define levels at which impurities/degradants should beidentified.ICH Q3A covers drug substances and Q3B covers drug products. Th...
