Abstract
Topical pharmaceutical compositions containing a specific 6-amino-1,2-dihydro-1-hydroxy-2-iminopyrimidine component and a penetration-enhancing vehicle are disclosed. The vehicle comprises a binary combination of a C.sub.3 -C.sub.4 diol or C.sub.3 -C.sub.6 triol and isocetyl alcohol polar lipid compound. The vehicle provides marked transepidermal and percutaneous delivery of the iminopyrimidine compound. These compositions, when applied topically, act to stimulate the growth of mammalian hair on the body.
