The Brazilian Chamber of Deputies has passed a request for urgent processing of a bill that declares the medications Mounjaro and Zepbound as having 'public interest'. This will allow for the breaking of their patents, which is seen as a significant step towards enhancing public health by making these drugs more accessible. The bill received overwhelming support, with 337 votes in favor and only 19 against, highlighting a strong legislative focus on public health concerns.

Opposition to the bill has emerged from the Novo party, with Deputy Adriana Ventura arguing that the legislation represents a direct violation of intellectual property rights. The opposition, however, allowed its members to vote freely, indicating a mix of views among lawmakers regarding the implications of patent breaks on innovation and public welfare. Mário Heringer, the bill's author, argues that this measure would serve as a crucial tool for public health, especially for addressing several comorbidities associated with obesity.

Both Mounjaro and Zepbound contain tirzepatide as their active ingredient and have been primarily used for weight loss treatments. The approval of this bill could set a precedent for how Brazil handles pharmaceutical patents going forward, potentially balancing the needs for public health against the rights of pharmaceutical companies to protect their innovations. The implications of this decision could be far-reaching in terms of drug accessibility and healthcare affordability in Brazil.
