Caffeine is the drug of choice for the treatment of apnea of prematurity. Although it has been used abroad for nearly 50 years, it has only begun to be widely used in China in recent years. There is still no consensus on the timing of caffeine initiation and discontinuation at home and abroad up to now. The efficacy and safety of caffeine under the standard-dose regimen have been confirmed, but the apnea symptoms of some preterm infants are still poorly controlled. The high-dose regimen is more effective, but the potential adverse effects are still worrisome. In addition, the necessity for the therapeutic drug monitoring of caffeine remains debatable since the effective blood concentration range is still controversial. Therefore, the pharmacokinetic characteristics of caffeine in premature infants, as well as the efficacy, safety, and effective blood concentration range under different dosage regimens were summarized. Of note, the research progress of the therapeutic drug monitoring and dose regimen optimization of caffeine were also discussed.
