|Other names||MyrB, Myrcludex-B|
The most common side effects include raised levels of bile salts in the blood and reactions at the site of injection.
Bulevirtide works by attaching to and blocking a receptor (target) through which the hepatitis delta and hepatitis B viruses enter liver cells. By blocking the entry of the virus into the cells, it limits the ability of HDV to replicate and its effects in the body, reducing symptoms of the disease.
Bulevirtide was approved for medical use in the European Union in July 2020.
Mechanism of action
The hepatitis B virus uses its surface lipopeptide pre-S1 for docking to mature liver cells via their sodium/bile acid cotransporter (NTCP) and subsequently entering the cells. Myrcludex B is a synthetic N-acylated pre-S1 that can also dock to NTCP, blocking the virus's entry mechanism.
The drug is also effective against hepatitis D because the hepatitis D virus is only infective in the presence of a hepatitis B virus infection.
