Will Daprodustat interact with other drugs and analysis of common contraindication combinations?

Daprodustat is an oral small molecule HIF-PH (hypoxia-inducible factor- prolyl hydroxylase) inhibitor, mainly used for the treatment of anemia related to chronic kidney disease. It inhibits HIF-PHenzyme activity to stabilize the HIF-α subunit in a hypoxic state, thereby promoting erythropoietin (EPO) expression and bone marrow red blood cell production, thereby improving anemia symptoms. Due to the systemic metabolism of daprostat, its pharmacokinetics in the body is easily affected by other drugs, so potential drug interactions need to be highly paid attention to in clinical practice.

Daprostat mainly relies onCYP2C8 for metabolism, and CYP3A4 may also be involved in its metabolism. Therefore, strong CYP2C8 inhibitors (e.g., fluvastatin, politraline) may lead to elevated plasma concentrations and increase the risk of hypertension, thrombosis, or cardiovascular events. On the contrary, CYP2C8 inducers (such as rifampicin, carbamazepine) will accelerate the metabolism of daprexostat and reduce the blood concentration of the drug, thereby reducing the efficacy and leading to unsatisfactory improvement of anemia. Clinically, potential interactions should be carefully evaluated and necessary dosage adjustments should be made based on the patient's previous medication history.

In addition, daprostat may interact with other erythropoiesis-stimulating drugs, such as recombinant human erythropoietin. When used in combination, hemoglobin levels need to be strictly monitored to avoid increased blood viscosity and increased risk of thrombosis. Patients with chronic kidney disease are often accompanied by hypertension and cardiovascular disease. Therefore, when using anticoagulants (such as warfarin) and antiplatelet drugs (such as aspirin, clopidogrel) in combination, they need to pay attention to the risk of bleeding and regularly monitor coagulation function and blood pressure.

Drug interactions between daprostat and antihypertensive drugs and diuretics are also possible. Antihypertensive drugs may affect blood pressure control, and diuretics may cause abnormalities in serum potassium or electrolytes. While daprixostat improves anemia, it may also affect blood viscosity and circulatory system burden. Therefore, during combined medication, blood pressure, electrolyte levels, and renal function need to be dynamically monitored to ensure safety.

Common contraindicated combinations include severe hepatic impairment, high risk of thrombosis, uncontrolled hypertension, and additive use with other erythropoiesis-stimulating drugs. For these high-risk patients, daplestat should be used with extreme caution and dose adjustments or alternative therapies should be selected if necessary. Doctors should conduct a comprehensive assessment before prescribing drugs, including blood pressure, hemoglobin, liver and kidney function and drug use history, to ensure that patients use it within a safe range.

In terms of clinical management, it is recommended that patients undergo regular follow-up during treatment, monitor changes in hemoglobin, blood pressure, electrolytes, and liver and kidney function, and promptly detect abnormal reactions and intervene. For patients who take it for a long time, they also need to pay attention to the risk of cardiovascular events and thrombosis to ensure that the drug can improve the efficacy of anemia while minimizing potential drug interactions and the incidence of adverse events. Through individualized dose adjustment and scientific monitoring, daprostat can achieve safe and effective anemia treatment.
