Claims of efficacy
United Kingdom ／ MHRA / PMCPA
An advertisement for a medicinal product with a UK marketing authorisation must comply with the particulars listed in the summary of product characteristics, must encourage rational use by presenting the product objectively without exaggerating its properties, and must not be misleading.
英国販売承認を有する医薬品の広告は製品概要（SmPC）の記載事項に適合しなければならず、製品特性を誇張せず客観的に提示して合理的使用を促さなければならず、誤認を与えてはならない。
Note
The Blue Guide adds that an advertisement may include statements not in the SmPC provided they are substantiated and not inconsistent with it.
