Preclinical Pharmacokinetics Testing Services

The Absorption Systems Difference

We take a truly end-to-end approach to preclinical PK studies. From formulation to PK parameters, our experienced team have been supporting DMPK for over 30 years. Our combined expertise in both in vitro and in vivo preclinical PK studies mean we know the right questions to ask and how to answer them, across model systems. We also recognise the time-sensitive nature of these studies and offer rapid turnaround times that support drug discovery timelines. 

FREQUENTLY ASKED QUESTIONS

What species do you work with?

We work with a range of preclinical models that enables us to select the most suitable model for a particular dose route, treatment regimen or endpoint. Our models include:

  • Dog
  • Guinea Pig
  • Mouse
  • Porcine
  • Rabbit
  • Rat

 

Do you work with specialized animal models?

 

What dose routes do you use?

Our scientists are experienced in a range of dosage routes, including more specialised routes. We have a selection of different preclinical models to match suitable routes of administration to:

  • Routine: IV, PO, SC, IM, IP
  • Standard: Ophthalmic, Dermal, Intranasal, Intraoral, Buccal
  • Specialty: GI (ID, IJ, IC), IT, Intra-articular
