General Description
Lypressin is synthetic 8-L-lysine vasopressin,a polypeptide similar to ADH. The lysine analog isconsidered more stable, and it is absorbed rapidly from thenasal mucosa. Lypressin (Diapid) is pharmaceutically availableas a topical solution, spray, 50 pressor units(185 g)/mL in 5-mL containers. Usual dosage, topical (intranasal),one or more sprays applied to one or both nostrilsone or more times daily.
