This invention relates to novel homotopic prodrugs and medicaments and methods for their preparation, testing and use. In one embodiment, the homotopic prodrug has the general formula
wherein
is a biologically-active moiety comprising a carboxylic acid functional group, and R
b
is a homotopically-symmetrical alcohol bonded to the biologically-active moiety through the carboxylic acid functional group to form an ester linkage, as well as optical isomers, enantiomers, pharmaceutically acceptable salts, biohydrolyzable amides, esters, and imides thereof and combinations thereof.
