Treatment with ursodeoxycholic acid (UDCA) can result in improvement in liver function tests, including alkaline phosphatase (ALP)1
- Once diagnosed, all patients should be treated with UDCA; however, a considerable number of patients may have an inadequate response to UDCA1-4
- In patients with primary biliary cholangitis (PBC) who present with abnormal ALP, treatment with UDCA can result in improvement in liver function tests, including ALP, within a few weeks1
- 90% of the improvement usually occurs as early as 6 months1
- About 20% of patients will have normalization of liver biochemistries after 2 years5
- A further 15% or 35% of the total will have normalization by 5 years1
- After initiating treatment with UDCA, monitor patients after 3 to 6 months to determine if ALP has been lowered and subsequently monitor every 3 to 6 months1
