Tryngolza
Tryngolza (olezarsen) is an prescription medication used along with a low-fat diet to lower triglyceride (fat) levels in adults with familial chylomicronemia syndrome (FCS). It’s an injection given once a month under the skin, either around the stomach or the outer thigh. Injections can also be given in the back of the upper arm if someone else is helping you. Potential side effects include injection site reactions such as swelling, redness, and irritation where the medication was injected.

How Tryngolza (olezarsen) works
People who have FCS have problems breaking down triglycerides, leading to very high levels of triglycerides in their blood. This raises the risk for a serious condition called pancreatitis, or inflammation of the pancreas.
Tryngolza (olezarsen) is an APOC-III antisense oligonucleotide (ASO). It works on apolipoprotein C-III (apoC-III), a protein responsible for keeping triglycerides (fats) in the blood. Specifically, it blocks the creation of apoC-III so less of it is made. This helps your body break down triglycerides more easily, which lowers levels of triglycerides in the blood.
