Pharmaceutical R&D

A solid R&D platform is the foundation of a successful pharmaceutical program. Government and industry clients at all stages of the drug discovery cycle turn to SRI Biosciences to rapidly identify and optimize new drug leads and move them toward preclinical development.

SRI Biosciences applies its more than 50 years of experience to solve challenges in formulation, drug delivery development, and the characterization of small molecule drugs and biologics.

SRI's approach to drug formulation is customized to the needs of clients and partners. Services range from the preparation of dose formulations for preclinical in vitro and in vivo safety studies, to the design of finished product dosage forms for clinical trials.

SRI also provides pharmaceutical R&D support and services in these areas:

Our pharmaceutical R&D services meet worldwide stringent regulatory requirements. SRI studies are conducted under current Good Laboratory Practice (GLP) and Good Manufacturing Practice (cGMP) regulations.
