From WikiMD's Wellness Encyclopedia

What is Alpha-1-Proteinase Inhibitor (Human)?[edit | edit source]

GLASSIA is an Alpha1-Proteinase Inhibitor (Human) (Alpha1-PI) used to increase the levels of the alpha1-antitrypsin (AAT) protein in your blood and lungs.

What are the uses of this medicine?[edit | edit source]

  • GLASSIA is a liquid medicine containing human Alpha1-Proteinase Inhibitor (Alpha1-PI) also known as alpha1-antitrypsin (AAT), which is purified from human blood.
  • The main purpose of infusing GLASSIA is to increase the levels of the AAT protein in your blood and lungs.
  • AAT protein protects the lung tissue by blocking certain enzyme-caused damage.
  • Such damage can lead to severe lung disease, such as emphysema.

Limitation of Use:

  • The effects of increasing the AAT protein levels with GLASSIA or any other Alpha1-PI product on worsening pulmonary function and progression of emphysema have not been proven in clinical trials.
  • The long-term effects of AAT replacement and maintenance therapy with GLASSIA have not been studied.
  • GLASSIA is not intended as a therapy in individuals with lung disease other than severe Alpha1-PI deficiency.


How does this medicine work?[edit | edit source]

  • Alpha1-PI deficiency is a chronic, autosomal, co-dominant hereditary disorder characterized by reduced levels of Alpha1-PI in the blood and lungs.
  • Smoking is an important risk factor for the development of emphysema in patients with Alpha1-PI deficiency3.
  • Because emphysema affects many, but not all individuals with the more severe genetic variants of Alpha1-PI deficiency (AAT deficiency), augmentation therapy with Alpha1-Proteinase Inhibitor (Human) is indicated only in patients with severe Alpha1-PI deficiency who have clinically evident emphysema.
  • The main purpose of infusing GLASSIA is to increase the levels of the AAT protein in your blood and lungs.
  • AAT protein protects the lung tissue by blocking certain enzyme-caused damage.
  • Such damage can lead to severe lung disease, such as emphysema.
