Glyset Vita rDNA is a sterile, clear solution of Glyset Vita human insulin analogue for subcutaneous injection/infusion or intravenous injection. This is a blood glucose lowering agent with an earlier onset of action. It produces a more rapid onset of action compared to soluble human insulin. Glyset Vita is homologous with regular human insulin with the exception of a single substitution of the amino acid Proline by aspartic acid in position B28, and is produced by recombinant DNA technology.
