The group is well-versed in the management of authorisations issued by COFEPRIS, the review of research protocols and regulatory compliance review relating to the storage, distribution, labelling and importation of medicines and medical devices. Leadership of the team is split between counsels Enrique Muñoz Guízar and Carlos Fernando Castilla. Muñoz Guízar specialises in environmental law and regulatory matters relating to healthcare, natural resources, and consumer protection; Castilla handles dispute resolution, environmental and regulatory law.
