Is it necessary to continue taking pirtobrutinib without stopping it?

Pirtobrutinib (pirtobrutinib) is a new non-covalent reversible BTK inhibitor, mainly used to treat mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL) and other B cell malignant tumors. Because of its unique targeting mechanism, it can overcome the problems caused by resistance to traditional BTK inhibitors (such as ibrutinib), so it is considered to be one of the important treatment options for refractory or relapsed patients.

Under normal circumstances, it is recommended to continue taking pitobrutinib during treatment until disease progression or intolerable adverse reactions occur. This type of targeted drugs does not have a strictly prescribed course of treatment like some chemotherapy drugs, but is dynamically adjusted based on efficacy and individual response. Stopping medication may lead to rapid rebound or relapse of the disease, especially in patients whose disease control is not yet stable.

However, during the actual treatment process, if the patient develops serious side effects after taking the medication, such as infection, high blood pressure, bleeding tendencies, or abnormal liver function, the doctor may recommend suspending, reducing the dose, or evaluating whether to change the medication. In these cases, it is not that "the medication cannot be stopped", but individualized risk assessment and medication adjustment are required to ensure safety.

In general, Pitobrutinib is a maintenance treatment drug, which emphasizes long-term continuous use to maintain efficacy. Patients should not stop taking the drug or reduce the dose on their own. Interrupting treatment may worsen the condition or even increase the risk of drug resistance. If any discontinuation of medication or adjustment of the regimen is required, it should be done strictly under the guidance of a professional hematologist, and changes in the condition should be closely monitored to ensure continuity and effectiveness of treatment.
