Investigation of drug delivery by iontophoresis in a surgical wound utilizing microdialysis.

abstract：:Primaquine, an 8-aminoquinoline antimalarial, is shown to undergo unexpectedly rapid aromatic proton exchange with the medium. At a pH less than 4, the exchange of C-5 is so fast as to be unmeasurable by proton nmr methods. At a pH of 6-6.5 the half-time for exchange is 4 to 5 minutes. This unexpectedly high rate of e...
