Stabilization of botulinum toxin type A during lyophilization.
Applied and environmental microbiology 1992;
58(
10):.
Botulinum toxin for medical use is diluted to very low concentrations (nanograms per milliliter); when it is preserved by lyophilization, considerable loss of activity can occur. In the present study, conditions that gave > 90% recovery of the toxicity after lyophilization of solutions containing 20 to 1,000 mouse 50% lethal doses per ml were found. Toxicity was recovered upon drying 0.1 ml of toxin solution when the pH was maintained below 7 and bovine or human serum albumins were used as stabilizers. Various other substances tested with albumin, including glucose, sucrose, trehalose, mannitol, glycine, and cellibiose, did not increase recovery on drying.
