Analytic method development, validation and transfer are key elements of any pharmaceutical development program. This technical brief will focus on development and validation activities as applied to drug products. Often considered routine, too little attention is paid to them with regards for their potential to contribute to overall developmental time and cost efficiency.

Methods are developed and validated to analyze in-process, finished product and stability samples, as well as swabs to verify the cleanliness of manufacturing equipment.

Typically, methods for in-process, uniformity of dosage units and dissolution sample analysis are developed and validated using UV, HPLC, UPLC, or GC procedures.

Methods used to perform chemical assay, identification, related substances/impurities or chiral purity testing on API and finished drug product are typically developed and validated using HPLC, UPLC or GC.

Methods developed for stability sample analysis are validated to ensure they are stability indicating.

All validations are performed according to FDA-ICH guidelines, client-approved protocols and standard operating procedures.

Method Validation

By working with Medicilon, you gain an experienced partner with a good working knowledge of method validation requirements suitable for different phases of development. To ensure methods meet regulatory requirements, we follow relevant ICH guidelines such as ICH Q2(R1) or compendia guidance in combination with client-specific protocols.

A Nickel-Catalyzed Reductive Alkylation of Aryl Bromides and Chlorides for Sp3-Sp2 Bond Formation

In 2012, a nickel-catalyzed reductive alkylation method of aryl bromides and chlorides was reported. Under the optimized conditions, a variety of aryl and vinyl bromides as well as active aryl chloride can be reductively coupled with alkyl bromides in high yields. The protocols were highly functional-group tolerant and the reactions were not air or moisture sensitive. The reaction showed different chemoselectivity than conventional cross-coupling reactions. Substrates bearing both anelectrophilic and nucleophilic carbon resulted in selective coupling at the electrophilic carbon (R-X) and no reaction occurred at the nucleophilic carbon (R-[M]). The 2010 Nobel Prize in Chemistry was awarded for the Pd-catalyzed cross-coupling, and in the past decade the progress in cross-coupling has not only had a significant impact on academic research but has also influenced the industrial synthetic application. The transition-metal-catalyzed union of nucleophilic organo-boronic acids with elect...

What is Toxicokinetics?

Toxicokinetics is essentially the study of “how a substance gets into the body and what happens to it in the body”. Four processes are involved in toxicokinetics. The study of the kinetics (movement) of chemicals was originally conducted with pharmaceuticals and thus the term pharmacokinetics became commonly used. In addition, toxicology studies were initially conducted with drugs. However, the science of toxicology has evolved to include environmental and occupational chemicals as well as drugs. Toxicokinetics is thus the appropriate term for the study of the kinetics of all toxic substances. Frequently the terms toxicokinetics , pharmacokinetics , or disposition may be found in the literature to have the same meaning. Disposition is often used in place of toxicokinetics to describe the time-course of movement of chemicals through the body (that is, how does the body dispose of a xenobiotic?). The disposition of a toxicant along with its’ biological reactivi...
