To What Extent can the Calculation of ADMET of Candidate Drugs be Predicted?
The discovery and development of new drugs is expensive & time-consuming! Whether a candidate can become a medicine is a work that R&D personnel continue to explore! When a molecule has obtained the desired drug effect, the work of preparing the drug begins to spread, and the research work of “absorption-distribution-metabolism-excretion-toxicity” (ie ADMET) is alsoRead more

How a Pill Accomplishes its Mission in the Body-ADME
Drugs enter the body through the four processes of absorption, distribution, metabolism, and excretion, but the four processes of different administration routes have their own advantages. Today we talk about the most common oral drug absorption and metabolism processes in the digestive tract. After oral administration of the drug in the gastrointestinal tract, it entersRead more

Talking about Pharmacokinetics PK
Pharmacokinetics (pharmacokinetics, PK) and pharmacodynamics (pharmacodynamics, PD), in fact, can be described as key research content, the two complement each other and are indispensable. PK refers to the quantitative study of the changes in the in vivo processes such as absorption (A), distribution (Distribution, D), metabolism (Metabolism, M) and excretion (Excretion, E) of drugs inRead more

What are the DMPK Parameters?
DMPK Parameters: Peak drug concentration (Cmax) The highest blood drug concentration after administration. This parameter is an important indicator reflecting the absorption rate and degree of absorption of drugs in the body.Peak time (Tmax)    the time required to reach the peak concentration of the drug after administration. This parameter reflects the rate at which theRead more
