PURPOSE: A film coating formulation with improved pantothenic acid or its salt is provided to reduce the deviation of pantothenic acid content and easily administer. CONSTITUTION: A film coating formulation is produced by coating a solid formulation containing pantothenic acid or its salt with a film layer containing pantothenic acid or its salt. The mass ratio of the pantothenic acid or its salt and film substrate is 1:99-95:5. The film substrate is water soluble and/or soluble in stomach. The film substrate is methyl cellulose, hydroxypropyl cellulose, hydroxypropylmethylcellulose, polyvinyl pyrrolidone, carboxyvinyl polymer, polyvinyl alcohol, aminoalkyl methacrylate copolymer E or polyvinyl acetal diethylamine acetate.
