The agency will tighten rules for the import and handling of weight-loss pens
Director Daniel Pereira stated that Anvisa will establish new “individualization elements” as a requirement to authorize the manipulation of tirzepatide, but did not detail what they will be. This year, Anvisa carried out 11 inspections in the largest compounding pharmacies in the country. Eight pharmacies and one importer were closed due to irregularities. In one of them, the agency seized all batches of tirzepatide imported for the production of pens.
At the moment, Only the pharmaceutical company Eli Lilly has authorization to market tirzepatide in Brazil, under the name Mounjaro. But the current rule provides for authorization for the compound to be manipulated and sold by compounding pharmacies in specific cases, to serve a certain patient who does not adapt to the doses made available by the industry, for example. What Anvisa has verified, however, is large-scale production that is not compatible with individualized use.
According to Anvisa, from November last year until now, more than 100 kilos of tirzepatide IFA were imported, which would be enough to produce around 20 million 5 mg pens.
