Pregnancy and lactation

Pregnancy category: C

Lactation: not known if distributed into breast milk, use caution

 

Pregnancy categories

A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

NA: Information not available.

 

Pharmacology of Aralast NP, Glassia (alpha 1 proteinase inhibitor)

Mechanism of action

Purified human alpha-1-proteinase inhibitor (alpha-1-antitrypsin, ATT) inhibits serine proteases such as neutrophil elastase in lungs; alpha1-antitrypsin deficienty leads to the development of emphysema resulting from increased elastic damage in the lung

Source: Human plasma donors

 

Pharmacokinetics

Half-life elimination: 5-6 days

Vd: 3.5 L

Peak plasma time: 1 hr (3 weeks to achieve threshold levels)

Metabolism: Undergoes catabolism in the intravascular space; 33% of AAT is catabolized per day

 

Administration

IV Preparation

Use aseptic technique

Reconstitution requires no more than 5 min for 0.5 g vial and no more than 10 min for a 1 g viaL

Do not shake contents of the vial; do not invert vial until ready to withdraw contents

When reconstitution procedure is strictly followed, a few small particles may remain; will be removed by microaggregate filter

 

IV Administration

For IV infusion only

IV infusion rate

  • Aralast NP, Prolastin C, Zemaira: Not to exceed 0.08 mL/kg/min
  • Glassia: 0.04 mL/kg/min

 

Storage

Unopened vials

  • Aralast NP, Prolastin C, Zemaira: Temperatures not to exceed 25°C (77°F); avoid freezing (may damage diluent vial)
  • Glassia: 2-8 °C (36-46 °F); do not freeze

Opened vials

  • Store at room temperature
