Pharmacology of Alecnib 150 Mg (Alectinib)

Alecnib (Alectinib) is a selective ALK inhibitor that works by blocking the action of the ALK protein. This protein is found in some cancer cells, where it plays a role in abnormal cell growth. By inhibiting ALK, Alecnib helps to stop the growth and spread of cancer cells, thereby controlling the disease progression in ALK-positive cancers.

 

Mechanism of Action:

Alecnib binds to the ALK protein, preventing its activity and halting tumor growth. This action also inhibits the spread of cancer to other parts of the body, particularly in the lungs, where it is most commonly found.
