Lusutrombopag is an oral medication used to treat thrombocytopenia (low platelets) in adults with chronic liver disease who are scheduled to have a medical or dental procedure. Lusutrombopag works by increasing the number of platelets in the blood, which helps to reduce the risk of bleeding during and after the procedure. It is not a substitute for other measures to prevent bleeding during the procedure, and it should not be used to treat bleeding caused by low platelets.
Lusutrombopag, sold under the brand name Mulpleta among others, is a medication used to address a specific issue related to blood cells in adults with chronic liver disease [1, 2]. Here's a breakdown of what it does:
- Increases Platelet Count: Lusutrombopag works by boosting the production of platelets in the bone marrow [1, 2]. Platelets are blood cells that help with clotting and prevent excessive bleeding.
- Chronic Liver Disease and Procedures: This medication is specifically indicated for adults with chronic liver disease who are scheduled for a medical or dental procedure [1]. Chronic liver disease can cause low platelet counts, and Lusutrombopag helps raise them before a procedure to reduce bleeding risk.
Here's a deeper look at how Lusutrombopag works:
- Thrombopoietin Receptor Agonist: Lusutrombopag acts like a chemical messenger by mimicking a protein called thrombopoietin [2]. Thrombopoietin naturally stimulates the bone marrow to produce platelets.
- Increased Megakaryocyte Activity: By mimicking thrombopoietin, Lusutrombopag binds to receptors on megakaryocytes, which are the cells in the bone marrow that mature into platelets [2]. This binding increases megakaryocyte production and maturation, ultimately leading to more platelets.
Things to Consider with Lusutrombopag:
- Short-Term Use: Lusutrombopag is typically taken for a short period, usually just 7 days, before a scheduled procedure [1].
- Potential Side Effects: Headaches are the most common side effect, but there can be others [2]. It's important to discuss any potential risks with your doctor.
- Increased Blood Clot Risk: There's a potential increased risk of blood clots with Lusutrombopag, especially in patients with underlying risk factors [2]. Your doctor will weigh this risk against the benefit of using the medication.
