How EKTERLY Works

EKTERLY halts the attack

EKTERLY works by blocking plasma kallikrein, which is a protein that plays a key role in swelling in hereditary angioedema (HAE) attacks.

• 

  In people with HAE, plasma kallikrein becomes overactive.

• 

  When plasma kallikrein is overactive, excessive fluid leaks through the walls of blood vessels and into body tissues.

• 

  Increased fluid buildup leads to the swelling that people with HAE experience during
  an attack.

• 

  EKTERLY works to stop attacks from getting worse by blocking plasma kallikrein.
