What is alpha 1-proteinase inhibitor (Aralast, Aralast NP, Glassia, Prolastin, Prolastin-C, Zemaira)?
Alpha 1-proteinase inhibitor is a protein, also called alpha 1-antitrypsin. This protein occurs naturally in the body and is important for preventing the breakdown of tissues in the lungs.
In people who lack the alpha 1-antitrypsin protein, breakdown of lung tissues can lead to emphysema (damage to the air sacs in the lungs).
Alpha 1-proteinase inhibitor is used to treat alpha 1-antitrypsin deficiency in people who have symptoms of emphysema.
Alpha 1-antitrypsin deficiency is a genetic (inherited) disorder and alpha 1-proteinase inhibitor will not cure this condition.
Alpha 1-proteinase inhibitor may also be used for purposes not listed in this medication guide.
