    • PROBLEM TO BE SOLVED: To provide a 2-(1-amino-1-carboxy-2-substituted ethyl)-1-fluorocyclopropanecarboxylic acid derivative exhibiting excellent pharmacological actions by introducing a fluorine atom onto a cyclopropane ring contained in a basic skeleton of 2SR- and 2RS-2-amino-2-(1SR, 2SR-2-carboxycyclopropan-1-yl)propanoic acid derivative. SOLUTION: The medicinal preparation or the medicinal composition comprises the 2-(1-amino-1-carboxy-2-substituted ethyl)-1-fluorocyclopropanecarboxylic acid derivative represented by formula [I] or a medicinally acceptable salt thereof, or a hydrate thereof. In the formula, R 1 is a hydrogen atom, or a group represented by the formula: -CHR 4 R 5 (wherein R 4 and R 5 are the same or different and are each a hydrogen atom, a 1-10C alkyl group, a 2-10C alkenyl group, a naphthyl group or a naphthyl group substituted with 1-7 halogen atoms, or the like); and R 2 and R 3 are the same or different and are each a hydrogen atom, a 1-10C alkyl group, a 2-10C alkenyl group or a 2-10C alkynyl group, or the like.
