A scientist in protective gear uses a pipette in a laboratory, performing Discovery in vivo pharmacokinetics (PK) research with analytical equipment in the background.

Pharmaron provides comprehensive biologics pharmacokinetics (PK) services, including discovery PK, preclinical PK, and clinical PK services. Discovery and preclinical PK studies are conducted in AAALAC-accredited animal facilities by scientists who follow study protocols reviewed and approved by IACUC. Our experienced medical staff performs clinical PK studies in our clinical pharmacology center. 

The corresponding bioanalysis is performed in laboratories equipped with state-of-the-art instruments, led by bioanalytical scientists, to support discovery and preclinical and clinical PK needs. The studies can also be conducted in an environment meeting GLP or GCLP and GCP requirements, as outlined by ICH, FDA, EMA, and NMPA.
