Safety Pharmacology

Our safety pharmacology studies are designed to determine potential hazards and assist in the prediction of adverse effects. Because pharmacological responses may be unique, we work with you to design customized, detailed protocols for your studies.
  • CNS, respiratory
  • Functional Observational Battery (FOB) and motor activity
  • Supplemental safety pharmacology studies
    – GI, Renal

Metabolism studies

Ricerca’s Drug Metabolism and Pharmacokinetics (DMPK) specialists provide world–class expertise in selecting a testing strategy specific to your development stage and provide high–quality data necessary for intelligent decision making.
Ricerca is accredited by AAALAC International, which promotes the highest standards of animal care in the world.
