Standard dosage and usage of apalutamide (Ansenko) and suggestions for individualized medication adjustment

Apalutamide (Apalutamide) is a non-steroidal androgen receptor inhibitor, mainly used to treat patients with castration-resistant prostate cancer (CRPC) and high-risk non-metastatic castration-resistant prostate cancer (nmCRPC). By blocking the androgen receptor signaling pathway, apalutamide can inhibit prostate cancer cell proliferation, delay disease progression, and improve patients' metastasis-free survival.

The standard dosage is 240mg taken orally daily. It is recommended to take it continuously every day, preferably at a fixed time to maintain stable blood concentration. Apalutamide may be taken with food or on an empty stomach, but the tablet must be swallowed whole and not chewed, crushed, or dissolved. Patients should strictly follow the doctor's instructions and not skip doses or double doses to ensure efficacy and safety.

For patients with moderate liver function impairment, dose adjustment or medication interval extension may be considered under the guidance of a doctor; patients with severe liver function impairment may use it with caution or it is prohibited. For patients taking concomitant strong inhibitors of CYP3A4 or CYP2C8, the dose may need to be adjusted to avoid adverse reactions caused by elevated plasma concentrations. Elderly patients or those with cardiovascular disease also need to closely monitor blood pressure, heart rate and electrocardiogram, and adjust the dose according to tolerance.

During the medication period, patients should regularly review blood routine, liver and kidney function and thyroid function, as well as monitor bone density and cardiovascular indicators. If obvious fatigue, rash, joint pain or cardiovascular discomfort occurs, you should contact your doctor promptly for dose adjustment or short-term discontinuation. Through individualized adjustment and standardized monitoring, the risk of adverse reactions can be minimized while ensuring the efficacy, and long-term safe medication can be achieved.
