✦ Synopsis


The transepithelial transport of biosynthetic human growth hormone (hGH) formulated with the absorption enhancers didecanoylia-phosphatidylcholine (DDPC) and a-cyclodextrin (a-CD) was studied after intranasal administration to rabbits. Plasma concentrations of the hormone were determined until 240 rnin post administration by ELISA, and the absolute bioavailability was estimated to be in the vicinity of
