PBM: a complete guide to paying less at the pharmacy

At many Brazilian pharmacies, simply giving your CPF (Brazilian taxpayer ID) at checkout can result in large discounts on the price of a medication. The price difference can surprise consumers, who may become suspicious. This discount, however, is usually tied to a Drug Benefit Program (PBM).

This guide explains how PBMs work, the main programs in Brazil, market trends and official sources for reference.

PBM: what is it and what does it stand for?

In the Brazilian context, PBM stands for Programa de Benefícios em Medicamentos (Drug Benefit Program), although it originates from the international concept of Pharmacy Benefit Management, related to the management of pharmacy benefits.

It is a model in which the manufacturer or specialized companies subsidize part of the price of the medication, reducing the final price paid by the patient.

In Brazil, discounts offered by PBMs can exceed 70% of the maximum consumer price (PMC), as set by the Drug Market Regulation Chamber (CMED). This subsidy focuses mainly on continuous-use medications, for which cost is a critical factor in continuing treatment.

What is a PBM medication?

A PBM medication is not a distinct therapeutic class. It is a medication (brand-name, generic or similar) included in an active benefit program, defined by the manufacturer or by the PBM administrator, and available at participating pharmacies.

The list of participating medications changes over time and should be confirmed through each program’s official channels.

How do PBM registration and lookup work?

In most cases, access to the benefit requires prior registration. First, the patient identifies the pharmaceutical company responsible for the prescribed medication. Next, they register with the corresponding PBM program, providing their CPF and, when required, the details of the medical prescription.

After registering, the benefit can be looked up through the administrators’ portals or apps, which show the discount amount and the participating pharmacies.

How the PBM market has evolved in Brazil

The PBM market in Brazil has existed for more than 25 years and is established as a significant component of the ecosystem for access to medications. Today, an estimated 40,000 to 50,000 pharmacies are connected to PBM programs, about half of the establishments in the country.

This reach shows the maturity of the model, which has expanded beyond simple discount programs to include strategies that bring together healthcare, technology and wellness stakeholders.

Benefit models and integration with health plans

Beyond the traditional discount-per-purchase model, there are new types of PBM that come closer to broader coverage solutions. Some examples include:

• Programs with monthly pharmacy credits in exchange for a fixed payment, similar to a group benefit.

• Integration between health plans and PBMs, such as initiatives that add an annual pharmacy credit to health plans.

These models broaden the scope of the PBM, bringing it closer to international pharmacy benefit management practices.

Technology and the new role of the PBM

The traditional discount PBM is evolving. Today, advanced platforms use digital technology to connect preventive care to the purchasing experience, including:

• Apps that promote wellness, prevention and health education, beyond simple discounts on medications.

• Analytics solutions that help monitor treatment adherence and consumption patterns, reducing the risk of treatment interruption.

This technological transformation positions the PBM as a component of population health management, not just of access to medications.

Advantages and limitations of PBMs

PBMs offer clear advantages: lower costs for the patient, greater treatment adherence and loyalty to specific pharmaceutical products. At the same time, programs with coverage caps or restrictive rules may not fully cover all the medications in a treatment regimen. This can limit the impact in complex or high‑cost treatments.

Why is the PBM important for treatment adherence?

The cost of medication is one of the main reasons patients abandon treatment. Reducing the price directly at the point of sale, through PBM programs, helps more patients complete their treatment cycles, leading to better health outcomes and more efficient spending on medications.
