Kailas Thakker, Ph.D. – Co-Founder

Dr. Thakker earned her PhD in Pharmaceutical Chemistry at the University of Kansas working under Dr. Higuchi. She worked at US Pharmacopeia for 12 years, where she specialized in the development and validation of dissolution methods in the Drug Research and Testing Laboratory. Subsequently, Dr. Thakker held leadership positions at Sphinx Pharmaceuticals and BioAnalytika Laboratories. In 1994, Dr. Thakker exploited her years of experience evaluating drug product performance and leading analytical organizations to launch Analytical Solutions, Inc. (later to become Tergus) with a mission to provide quality analytical services to the pharmaceutical industry. With the emergence of newer, alternative dosage forms over the past 10 years, she has surfaced as a well-recognized global leader in the development of topical drug products, providing expertise in the development and validation of performance tests used to evaluate the transport of drugs across skin and other membranes (e.g., buccal, sublingual, vaginal, rectal).  Working with compendial and regulatory organizations, Dr. Thakker continues to strive toward improving public standards for topical and other dosage forms.

Since 1994, Dr. Thakker, has also had a focus on functional testing for semisolids. She has been involved with developing In Vitro Release Test (IVRT) methods for semisolid dosage forms.  Her work was helpful to many of sponsors and ultimately led to the development of the SUPAC-SS guidance document that the pharmaceutical industry follows now.  As a result of her pioneering work, Tergus has emerged as a leader in developing release rate methods for semisolid dosage forms. As a member of USP’s Advisory Panel to the then Biopharmaceutics Expert Committee, she helped draft chapters <3> and <1724>.  Her efforts and commitments in helping to develop and maintain public standards for the semisolid dosage  forms remains firm to date, and she is committed to continue these efforts as a newly elected member of USP’s Expert Committee on Dosage Forms for the revision cycle 2010-2015.
