Gleevec is a medicine used to treat cancer. It is a type of targeted therapy that specifically targets cancer cells and stops them from growing and dividing.

Mechanism of Action:
• Gleevec works by inhibiting a specific protein called tyrosine kinase, which is found in certain cells that cause cancer to grow and spread.
• This protein is responsible for triggering the growth and division of cancer cells.
• Gleevec blocks the activity of this protein, which stops cancer cells from multiplying and spreading.

Uses:
• Gleevec is used to treat certain types of cancer such as chronic myeloid leukemia (CML), gastrointestinal stromal tumors (GIST), and some types of skin cancer.
• It is also used to prevent the recurrence of certain types of cancer.

Side Effects:
• Gleevec can cause side effects such as nausea, vomiting, diarrhea, muscle cramps, and fatigue.
• It can also cause more serious side effects such as liver problems, low blood counts, and fluid retention.

Precautions:
• Patients must inform their doctor about any other medications they are taking, as Gleevec can interact with other drugs.
• Patients should also inform their doctor if they have any liver or kidney problems, as Gleevec can affect these organs.
• Pregnant women should not take Gleevec, as it can harm the fetus.

In conclusion, Gleevec is a targeted therapy used to treat certain types of cancer. It works by inhibiting a specific protein that triggers the growth and division of cancer cells. Patients must take precautions and inform their doctor about any other medications they are taking to avoid any potential interactions or side effects.
