Anvisa aprova Nurtec ODT, novo medicamento para tratamento de enxaqueca

Migraine sufferers experiencing moderate to severe headaches with nausea, vomiting, and light/sound sensitivity gain access to a new treatment option.
A new mechanism targeting the source of migraine pain itself
Nurtec ODT blocks CGRP protein, offering both acute and preventive treatment through a pathway different from older migraine drugs.

Por décadas, a enxaqueca foi subestimada como simples dor de cabeça, enquanto milhões de brasileiros enfrentavam crises incapacitantes sem respostas terapêuticas suficientes. A Anvisa aprovou na segunda-feira o Nurtec ODT, da Pfizer, um medicamento que inaugura uma nova classe de tratamento ao bloquear a proteína CGRP — responsável pela cascata inflamatória que origina a dor. A aprovação oferece, pela primeira vez, uma opção que age tanto no alívio agudo quanto na prevenção das crises, reconhecendo a enxaqueca como a doença neurológica séria que sempre foi.

  • Adultos com quatro ou mais crises de enxaqueca por mês vivem em estado de interrupção permanente — trabalho, relações e rotina comprometidos de forma recorrente.
  • Os tratamentos convencionais frequentemente falham nesse perfil de paciente, deixando uma lacuna terapêutica que o sistema de saúde brasileiro ainda não havia conseguido preencher.
  • O Nurtec ODT age por um mecanismo inédito: bloqueia a proteína CGRP, interrompendo a inflamação na origem da dor, em vez de apenas atenuar seus efeitos depois que a crise já se instalou.
  • A aprovação da Anvisa abre duas vias de uso — tratamento agudo no início da crise e uso preventivo regular — ampliando significativamente as possibilidades clínicas para médicos e pacientes.
  • O desafio imediato é garantir que o medicamento chegue com agilidade a quem mais precisa, especialmente diante das desigualdades de acesso ao sistema de saúde no Brasil.

A Anvisa aprovou na segunda-feira o Nurtec ODT, medicamento da Pfizer voltado para adultos que sofrem ao menos quatro crises de enxaqueca por mês — pacientes para quem os analgésicos comuns frequentemente não são suficientes.

A enxaqueca vai muito além de uma dor de cabeça intensa. É uma doença neurológica crônica que pode tornar impossível trabalhar, conviver com outras pessoas ou tolerar luz e som. Quando as crises se repetem quatro vezes ou mais ao mês, a condição deixa de ser uma interrupção ocasional e passa a moldar a vida inteira de quem a vive.

O que distingue o Nurtec ODT dos tratamentos anteriores é seu mecanismo de ação. Seu princípio ativo pertence a uma classe inteiramente nova de medicamentos para enxaqueca: em vez de apenas aliviar a dor após sua chegada, ele bloqueia a proteína CGRP, que está no centro do processo inflamatório responsável pela crise. Isso permite tanto interromper um ataque agudo quanto, com uso regular, reduzir a frequência com que as crises ocorrem.

Com a aprovação, os pacientes brasileiros que se enquadram no perfil indicado passam a contar com duas possibilidades: usar o medicamento no momento em que a enxaqueca começa ou adotá-lo de forma preventiva, em esquema regular. Para quem vive com quatro ataques mensais, a opção preventiva pode representar uma mudança concreta na qualidade de vida. A pergunta que permanece é com que velocidade esse novo recurso chegará às mãos de quem mais precisa.

Brazil's health regulator gave the green light on Monday to a new migraine medication that represents a shift in how doctors can treat one of the country's most debilitating neurological conditions. The drug, called Nurtec ODT, made by Pfizer, is designed for adults who experience at least four migraine episodes each month—the kind of patient for whom standard painkillers have often proven insufficient.

Migraine is not simply a bad headache. It is a chronic neurological disease that can render a person unable to work, unable to be around others, unable to tolerate light or sound. The pain itself ranges from moderate to severe, but it rarely comes alone. Nausea, vomiting, extreme sensitivity to light, extreme sensitivity to sound—these are the companions that make migraine so incapacitating. For someone experiencing four or more attacks per month, the condition becomes a permanent feature of life, not an occasional disruption.

What makes Nurtec ODT different is its mechanism. The active ingredient is rimegepanto hemisulfate sesquihydrate, which belongs to an entirely new class of migraine drugs. Rather than simply dulling pain after it arrives, this medication works by blocking the action of a protein called calcitonin gene-related peptide, or CGRP. This protein is central to the inflammatory cascade that produces migraine pain in the first place. By interrupting that process, the drug can both stop an acute migraine attack and, when taken regularly, prevent episodic migraines from occurring as frequently.

The approval from Anvisa, Brazil's National Health Surveillance Agency, opens two treatment pathways. Patients can use Nurtec ODT acutely—taking it when a migraine begins, with or without the visual disturbances that sometimes precede an attack. They can also use it preventively, taking it on a regular schedule to reduce how often migraines strike. For someone living with four attacks a month, the preventive option could mean the difference between a life interrupted by illness and a life that feels more stable.

The medication represents a recognition that migraine, long dismissed in casual conversation as a severe headache, is actually a serious medical condition requiring serious pharmaceutical innovation. Patients in Brazil who meet the criteria—adults experiencing frequent, severe episodes—now have access to a tool that works through a mechanism their previous treatments may not have addressed. The question now becomes how quickly this new option reaches the people who need it most.

Why does this drug matter specifically for people with four or more migraines a month?

Model

Because at that frequency, you're not dealing with occasional bad days anymore. You're dealing with a chronic condition that shapes your entire life. Standard painkillers stop working, or they work but leave you exhausted. A new mechanism—blocking CGRP instead of just masking pain—offers something genuinely different.

Inventor

What is CGRP, and why is blocking it significant?

Model

It's a protein your body releases during a migraine. It causes inflammation and pain. Most older migraine drugs work on different pathways entirely. This one goes directly at the source of the inflammation itself, which is why it can work both to stop an attack and prevent future ones.

Inventor

Can someone use this drug both ways—acute and preventive?

Model

Yes. That flexibility is important. Some days you might take it when you feel a migraine starting. Other days, if you're prone to frequent attacks, you might take it regularly to keep them from happening. It's not one or the other.

Inventor

Who benefits most from this approval?

Model

Adults in Brazil who have at least four migraines a month and haven't found relief elsewhere. That's a specific population, but it's also a population that's been waiting for options like this.

Inventor

What does this say about how Brazil treats neurological disease?

Model

It says the country's regulatory system is keeping pace with global pharmaceutical innovation. Migraine has been underfunded and undertreated for decades. Approvals like this one signal that's beginning to change.
