The subject compounds, which are adapted for the site-specific/sustained delivery of centrally acting drug species to the brain, are: (a) compounds of the formula [D--DHC] (I) wherein [D] is a centrally acting drug species, and [DHC] is the reduced, biooxidizable, blood-brain barrier penetrating lipoidal form of a dihydropyridine.revreaction.pyridinium salt redox carrier, with the proviso that when [DHC] is ##STR1## wherein R is lower alkyl or benzyl and [D] is a drug species containing a single NH.sub.2 or OH functional group, the single OH group when present being a primary or secondary OH group, said drug species being linked directly through said NH.sub.2 or OH function group to the carbonyl function of [DHC], then [D] must be other than a sympathetic stimulant, steroid sex hormone or long chain alkanol; and (b) non-toxic pharmaceutically acceptable salts of compounds of formula (I) wherein [D] is a centrally acting drug species and [DHC] is the reduced, biooxidizable, blood-brain barrier penetrating lipoidal form of a dihydropyridine.revreaction.pyridinium salt redox carrier. The corresponding ionic pyridinium salt type drug/carrier entitles [D--QC].sup.+ X.sup.- are also disclosed.
The invention provides a method for controlling mammalian body weight using a compound of the formula [E--DHC] (I) or a non-toxic pharmaceutically acceptable salt thereof, wherein [E] is an estrogen and [DHC] is the reduced, biooxidizable, blood-brain barrier penetrating, lipoidal form of a dihydropyridine.revreaction.pyridinium salt redox carrier. Novel compositions for weight control comprising a compound of formula (I) or its salt are also disclosed. A preferred compound for use in the subject method and compositions is an estradiol derivative, namely, 17 .beta.-[(1-methyl-1,4-dihydro-3-pyridinyl)carbonyloxy]estra-1,3,5(10)-trie n-3-ol.

The invention provides the use of a compound of the formula
[E-DHC] (I)
or a non-toxic pharmaceutically acceptable salt thereof, wherein [E] is an estrogen and [DHC] is the reduced, biooxidizable, blood-brain barrier penetrating, lipoidal form of a dihydropyridine#pyridinium salt redox carrier in the preparation of a medicament for controlling mammalian body weight. Novel compositions for weight control comprising a compound of formula (I) or its salt are also disclosed. A preferred compound for use herein is an estradiol derivative, namely, 17β-[(1-methy)-1,4-dihydro-3-pyridiny))carbony)oxy]estra-1,3.5(10)-trien-3-ol.
