Ocular pharmacokinetics

Iris Pharma can perform the regulatory program (GLP, validated).

Prior to proof of concept or efficacy studies, Iris Pharma suggests to quickly evaluate (non-GLP) the ocular pharmacokinetics of your compound or formulation. Iris Pharma may also be able to help you discriminate several preclinical formulations.
