About this trial
There's no unified recommendation in clinical practice regarding adjusting dosages for different patient types, especially when adverse events occur. While rivaroxaban typically doesn't require coagulation monitoring, in elderly patients, particularly those with multiple medications, finding appropriate lab indicators becomes crucial to gauge its anticoagulant effect. This aids in evaluating precise rivaroxaban dosing for the elderly, balancing bleeding risks and recurrence. Clinical pharmacological studies suggest that drug pharmacokinetics and pharmacodynamics in different populations can guide dosage optimization. Hence, this study aims to provide a basis for optimizing dosing regimens in high-risk elderly patients in China by exploring pharmacokinetic and pharmacodynamic indicators in clinical practice.
Eligibility criteria
Qualifiers
(1) Adult patients with objectively diagnosed acute symptomatic pulmonary embolism (with or without concurrent deep vein thrombosis) by imaging, who have completed acute anticoagulation and entered the anticoagulation maintenance phase; (2) Life expectancy greater than 3 months; (3) Meeting the indications for Xa factor inhibitor use; (4) Willingness to participate in this study, sign the informed consent form, and adhere to regular follow-ups.
Disqualifiers
