Alpha-1 Proteinase Inhib.(Hum)

Pronounced

"al-fa-1-PROE-teen-ase inhibitor"

Common brand names:

Prolastin

Uses

This medication is used to treat lung problems (emphysema) caused by a certain inherited disease (alpha-1-proteinase inhibitor deficiency). In people with this condition, lung damage is caused by elastase, a natural substance that the body needs to kill bacteria in the lungs. Normally, a protein (alpha-1-proteinase inhibitor) stops elastase from working when it is no longer needed. However, in people who do not make enough of this protein, elastase does not stop working and damages the lungs. This medication replaces the missing alpha-1-proteinase inhibitor and helps to prevent further lung damage.
