OPTI-ADME™ Panel

Type:Services
SUBTYPE:Transporter Assays
APPLICATION & SPECIALITY USES:ADME-Toxicology Products and Services
Keywords:DDIRegulatoryTransporters

Our OPTI-ADME Panel consists of the major transporters that affect ADME properties of drugs. Transporters in the panel can be used to investigate drug bioavailability, tissue distribution, excretion, and inter-individual variability in drug response. We provide customized OPTI-ADME Panel research services for rapid screening and more extensive, regulatory-compliant transporter studies.

In vitro ADME (Absorption, Distribution, Metabolism and Excretion) studies have long played a critical role in optimizing both pharmacokinetic (PK) and pharmacodynamic (PD) properties of drugs, thereby decreasing attrition rates in drug development. Because transporters regulate the cellular entry and exit of most small molecules, they are critical determinants of every aspect of drug ADME properties. In particular, many new chemical entities (NCEs) synthesized today are hydrophilic compounds with low cell membrane permeability, which are more dependent on transporters to achieve acceptable bioavailability, desirable tissue distribution, and optimized PK profiles.

The table below lists transporters that are associated with serious adverse events.
