Guidance on the correct taking time of Maribavir/Yitazhi

Maribavir is an oral anti-CMV drug that is mainly used for adult patients with refractory CMV infection after stem cell or organ transplantation. The correct timing and method of administration are critical to drug efficacy, tolerability, and long-term patient management. Both the drug instructions and clinical practice emphasize that maribabavir is taken orally twice a day, with each dose of 400 mg. It can be taken on an empty stomach or with food. Food intake will not significantly affect drug absorption, so patients can flexibly choose the time to take medication according to their own lifestyle habits to improve compliance.

In actual use, it is usually recommended to take the medicine at a fixed time in the morning and evening, with an interval of about 12 hours, to ensure stable blood concentration and maintain continued inhibitory effect on the CMV virus. This dosing interval helps maximize drug efficacy while reducing the risk of viral breakthrough caused by fluctuations in blood concentration. In addition, patients should understand the storage conditions of the drug before starting medication and avoid high temperature or humid environments to maintain drug stability and efficacy. For those who forget to take medication, they should be handled according to the guidance of a doctor. It is generally not recommended to take double the dose at one time to avoid increasing the risk of side effects.

Compared with intravenous drugs, the oral administration of maribavir significantly improves patients' convenience and quality of life, and is especially suitable for transplant patients who require long-term management. Clinical experience shows that rationally arranging medication time and strictly following the twice-daily rule can help maintain virological control and reduce clinical symptoms. Doctors usually adjust the medication regimen based on the patient's blood drug concentration monitoring and virological indicators to ensure sustained efficacy and safety.

In general, through the principles of fixed intervals, being able to be taken with food, and following the doctor's recommendations, patients can reduce the risk of adverse reactions while ensuring the efficacy of the drug, and provide reliable protection for the management of CMV in high-risk transplant patients
