Which of the following medications is administered via injection?

Evkeeza is an injectable medication used primarily for the treatment of certain genetic conditions related to high cholesterol, specifically in patients with homozygous familial hypercholesterolemia. It is administered via subcutaneous injection, which allows it to be absorbed directly into the bloodstream, providing a more rapid effect compared to oral medications.

In contrast, the other options listed are oral medications or formulations. Tricor, Lipofen, and Vascepa are all taken by mouth, which means they undergo gastrointestinal absorption before entering the systemic circulation. This key distinction of administration routes is what makes Evkeeza the correct answer in this case.
