Why DMPK is an essential part of early drug discovery.

  • Date: September 29th, 2020


Drug discovery or the process of developing a drug begins when there are no suitable medical products for a disease or clinical condition which is likely to be prone at masses. Basically, it is a process in medicine, pharmacology and biotechnology through which new medications are discovered or designed and later critically evaluated. This process comprises the identification of candidate medications, amalgamation, transmission, personation and evaluation.

About DMPK

In the process of drug discovery, the scientists not only have the pressure of formulating a superior drug to ones that are available and not have any adverse effects in standard safety tests. To keep the safety and efficacy evaluation afloat, DMPK (Drug metabolism and pharmacokinetics) is applied as an essential discipline in drug discovery.



Significance of DMPK in early drug discovery 

DMPK  outlines several properties of potential candidates and assesses its half-life, clearance, metabolic stability & bioavailability which means the portion that magnificently targets the body and indicates a positive active effect.

–The main object of DMPK studies in drug discovery is to screen multiple compounds and evaluating their intrinsic Drug metabolism and pharmacokinetic properties. 

–Its goal is to also implement further metabolism revisions on a subset of compounds that contribute to advance drug development.

–Through advance studies, dmpk scientist contributes to estimating the potential for drug-drug interactions (DDIs) taking place when unfavourable effects result from a patient taking several medications.

DMPK studies come alongside absorption, distribution, metabolism, excretion, and toxicity analysis (ADMET) of drug candidates. Its studies also offer an understanding of the dose regimen, toxicity level, therapeutic index, PK/PD relationships, & other PK parameters. 

–With the advancement of DMPK studies, drug discovery and development utilizes 2-4 doses of animal for testing. This benefits in understanding if the generic formulations of a compound fit as per the standards. 

DMPK and ADME in drug development 

In the early medicinal chemistry and lead optimization phase of drug discovery, the dmpk adme are critical steps that let the scientist make decisions whether a compound should be picked as a drug candidate.

Post identification of the candidate drug, the role of DMPK is to expand understanding the ADME and PK properties in relevant animal species and man in support of clinical drug development.

ADME are the four steps involved in Pharmacokinetics which specifically studies and designed to investigate how the body reacts to a drug. 

Absorption – what proportion of the drug is absorbed and the way quickly? (bioavailability)

Distribution Where is that the drug distribution within the body? what’s the speed and extent of the distribution?

Metabolism how briskly is that the drug metabolized? what’s the mechanism of action? What metabolite is made and is it active or toxic?

Elimination How is that the drug excreted and the way quickly?

Toxicity-Does this drug has a toxic aftereffect on organs and body’s system?

Metabolic stability DMPK assays are helpful when trying to work out the potential half-life of a compound when dosed to animals or humans. 

It regulates the steadiness of a test article during a sort of enzyme sources, including hepatocytes, liver microsomal preparations, hepatic cytosol, hepatic mitochrondrial fraction, hepatic S9 fraction, and membrane preparations from recombinant bacteria or eukaryotic cells.


The object behind pertaining the DMPK in early drug discovery is that it helps the scientist to assess it on various extensions to understand its inherent properties. It also aids in assurance about the drug candidate on how it will be cleared from the body without any deleterious aftereffect. Over the next decade and beyond in our discipline, it is in silico DMPK approaches that can most significantly impact the cost-effectiveness, speed and design quality of drug discovery projects.
