PROBLEM TO BE SOLVED: To provide uses of polypeptides derived from botulinum toxin and a pharmaceutical composition having more effective analgesic action. SOLUTION: Provided are a pharmaceutical composition containing polypeptide components free from non-toxin and nontoxic hemagglutinin (HA) among polypeptides derived from botulinum toxin as active components, more particularly, pharmaceutical composition containing polypeptides as active components, wherein the polypeptide components free from non-toxin and nontoxic HA have a molecular weight of about 150 kDa.
