enteric-coated zoledronic acid tablet MER-101
An oral tablet formulation containing zoledronic acid combined with a proprietary absorption enhancer for improved zoledronic acid gastrointestinal absorption with anti-bone-resorption activity. The third-generation bisphosphonate zoledronic acid binds to hydroxyapatite crystals in the bone matrix, slowing their dissolution and inhibiting the formation and aggregation of these crystals. This agent also inhibits farnesyl pyrophosphate synthase, an enzyme involved in terpenoid biosynthesis. Inhibition of this enzyme prevents the biosynthesis of isoprenoid lipids, donor substrates of farnesylation and geranylgeranylation during the post-translational modification of small GTPase signalling proteins, which are important in the process of osteoclast turnover. The proprietary absorption enhancer is a GRAS (generally-recognized-as-safe) food additive. Check for active clinical trials using this agent. (NCI Thesaurus)
