Pharmacology & Toxicology

The pharmacologists, toxicologists and study monitors at PHDS have experience in a variety of compounds and therapeutic areas. Our nonclinical resources are dedicated to getting the project to first-in-man studies. We place and monitor studies; obtain competitive bids with comparisons based on critical milestones; and design and review study protocols, considering dose selection, animal models, regimen, overall design and regulatory compliance.

PHDS has expertise in the following areas (our toxicology services are non-GLP):

l  Primary and secondary pharmacology

l  General toxicology (acute, subacute, subchronic and chronic)

l  Special toxicology

l  Genetic toxicology

l  Reproductive and developmental toxicology

l  Carcinogenicity, including the use of alternative models

l  Safety pharmacology

l  Absorption, distribution, metabolism and excretion (ADME) data

Safety Pharmacology

Safety pharmacology plays a critical role in the pharmaceutical industry, by providing valuable insight into a drug's potential adverse effects, preview what may be observed clinically and provide essential information about likely side effects on the major physiological systems of the body.

At PHDS, we understand your requirements for safety pharmacology testing in the changing environment of drug development. Our industry-leading scientists are innovative and investigative, and focus on improving existing models and developing new ones. Our broad GLP service offering enhances our ability to provide a complete range of pharmacology services, allowing full integration into a safety assessment program.
