In addition, understanding the pharmacokinetics of cobimetinib can also help patients better understand the behavior of drugs in the body.

Pharmacokinetics of cobimetinib

Pharmacokinetics is the science of studying the absorption, distribution, metabolism and excretion of drugs in the body. Understanding the pharmacokinetics of cobimetinib helps patients and doctors better understand the effects of drugs in the body and metabolism.

Absorption and distribution

Cobimetinib is rapidly absorbed after oral administration and widely distributed in the body. In healthy subjects and cancer patients, cobimetinib exhibits linear pharmacokinetics, that is, within a certain dose range, the exposure of the drug is proportional to the dose.

Metabolism and excretion

Cobimetinib is mainly metabolized by the liver and excreted through bile and urine. Oral administration of cobimetinib 60mg once a day reaches steady state after 9 days, with an average accumulation ratio of 2.4 times. This means that with continuous administration, the concentration of cobimetinib in the body will gradually accumulate and reach a stable level.

Warm reminder: Cobimetinib is an effective targeted therapy drug, but patients need to pay close attention to their physical reactions during medication. If any discomfort or adverse reactions occur, the doctor should be informed in time. Patients should also follow the doctor's advice and take the medicine on time and in the right amount. Do not adjust the dosage or stop the medicine on your own to avoid affecting the treatment effect.
