Is it really impossible to stop taking Seladelpar?

Seladelpar(Seladelpar) is a drug for primary biliary cholangitis (PBC) is an oral targeted drug whose core function is to regulate liver bile metabolism and anti-inflammatory signals by activating PPARδ receptors, thereby improving key indicators such as serum bilirubin and alkaline phosphatase (ALP), and slowing down liver cell damage and disease progression. Like most chronic disease drugs, Siladepa does not cure PBC, so efficacy depends largely on long-term continued use. Random discontinuation of medication may lead to a rebound in biochemical indicators such as serum bilirubin and ALP, and an increase in disease activity. Long-term discontinuation may even accelerate the occurrence of complications related to liver fibrosis or cholestasis.

However,“cannot discontinue medication” is not an absolute restriction but emphasizes the need to maintain long-term disease control. Clinically, doctors will evaluate whether the dose can be adjusted or try to observe drug withdrawal reactions based on the patient's condition stability, changes in liver function, combined medications, and potential risks. In some patients with long-term stable biochemical indicators, gradual reduction or intermittent medication may be explored, but this must be done under strict medical monitoring to prevent disease rebound. For PBC patients, the goal of continuous medication is to maintain normal bile flow, reduce liver cell damage, and delay the progression of the disease, rather than just relieving symptoms.

In addition, the risk of discontinuation is closely related to individual patient factors, such as age, liver function level, comorbid diseases, and past medical history. Patients with abnormal liver function or underlying diseases need to be extra cautious, as discontinuation of medication may lead to rapid deterioration of the disease. Patients should regularly review liver function and biochemical indicators during use, and maintain close communication with their doctors. Any dose adjustment or discontinuation should be done under professional guidance to ensure safety and efficacy

In general, continuous and regular medication is the key to ensuring the efficacy and disease control of Siladepa, and discontinuation of medication must be scientifically evaluated and gradual.
