About Us

Pharmtox Program – Drug Diversion and Compliance Program

Pharmtox developed a unique prescription drug screen program designed to provide physicians with important data about the treatment for their patients. Our primary goal is to enhance pharmacologic management decisions for physicians, provide objective data to assist in improving patient compliance, and to reduce prescription drug diversion and misuse. Developed by pharmacists, our program is focused on enhancing patient care.

Pharmtox Clinical Analysis Technology (PCAT™ )

We utilize an integrated software matrix that we developed called Pharmtox Clinical Analysis Technology (PCAT™) – to perform a comprehensive urine evaluation.  Our program concentrates specifically on identifying prescription medications and correlating them to prescribed therapy and potential drug interactions.

“Urine drug screening can be used to provide objective documentation showing adherence to the agreed-upon treatment plan, to aid in the diagnosis and treatment of the disease of addiction or drug misuse, if present, and to advocate for the patient in family and social issues.” Urine Drug Testing in a Clinical Practice: Dispelling the Myths and Designing Strategies. Heit, Howard MD et al., 2006 (CME Accredited)

Pharmtox is lead by a dedicated team of professionals with years of pharmaceutical experience. Meet our CEO.


MATTHEW WALK PHARM D, CEO

Matthew began working in a “mom and pop” pharmacy when he was 16 years old and quickly discovered he wanted to become a pharmacist. Graduating from the St. Louis College of Pharmacy with a Doctorate in Pharmacy in 2006, his desire to break away from the conventional pharmacy experience brought him to Pharmtox where he became CEO in 2009.

Since then, Matthew has created the Pharmtox Rapid-Exam division and developed the algorithms that drive PCAT— Pharmtox Clinical Analysis Technology.

Matthew is a member of the Los Angeles Entrepreneurs Organization, California Pharmacist Association, American Academy of Compounding Pharmacists, and the American Pharmacist Association.
