Buckets of Drugs 101: Understanding the Economics Behind What You Dispense

When evaluating the financial health of your pharmacy, it’s critical to understand how drugs are categorized—and how those classifications impact your purchasing strategy and reimbursement outcomes. Manufacturers, wholesalers, and PBMs all segment medications into distinct “buckets,” and each one carries its own implications for profitability, cash flow, and sourcing decisions.

Here’s a breakdown of the most common drug categories and how to navigate them strategically:

1. Brand Drugs: Low Margin, High Stakes

Brand-name drugs are typically manufactured by a single company and offer limited pricing flexibility. Margins on these items tend to be thin for both wholesalers and pharmacies, and they're often best sourced through your primary wholesaler. While some secondary vendors may carry a handful of brand drugs at competitive prices, the majority of access and volume will come through your primary relationship.

Key Takeaway: Brand drugs are a necessary part of your inventory, but they won’t be the profit drivers. Monitor your brand volume and manage expectations around margin.

2. Generics: The Profit Engine

Generics are where most pharmacies thrive. With dozens of sourcing options and aggressive competition among secondary suppliers, generics typically carry high margins and offer room to negotiate better pricing and volume discounts.

The more your pharmacy dispenses generics relative to brands or specialty items, the more likely you are to see stronger profitability metrics.

Key Takeaway: Generics should be the backbone of your strategy. Make sure you’re maximizing secondary sourcing opportunities while protecting primary incentives.

3. Specialty: High Risk, High Cost

Specialty drugs are a category shrouded in complexity. Typically used for chronic or high-risk conditions like cancer or autoimmune diseases, these drugs are expensive, tightly controlled by manufacturers, and often require net billing arrangements that can severely distort your purchasing ratios.

Unless your pharmacy is structured to handle the unique demands of specialty care, these items can negatively affect your cash flow and rebate performance.

Key Takeaway: Be cautious. Specialty drugs can drain your resources if not part of a planned service line.

4. GLP-1 Medications: The New Disruptor

With the explosion in popularity of drugs like Ozempic, Mounjaro, and Wegovy, many pharmacies are experiencing a surge in GLP-1 volume. But here’s the catch: these high-cost drugs can skew your purchasing ratios and potentially hurt your standing with your primary wholesaler.

It’s natural to assume that higher volume should lead to better pricing or incentives—but if the bulk of that volume is GLP-1s, it might have the opposite effect, dragging down your metrics.

Key Takeaway: Work proactively with your wholesaler to track and contextualize your GLP-1 purchasing. Don’t let these drugs distort your overall performance metrics.

5. Antipsychotics & Long-Acting Injectables: Hidden Opportunity or Silent Liability?

This bucket includes branded medications—often long-acting injectables used in behavioral health—that can hurt or help your pharmacy depending on how they’re sourced. Without a strategy in place, they function like any other expensive brand: low margin, high risk.

However, by setting up combo-med accounts or specialty sourcing arrangements, you may unlock deeper discounts that make these items more viable.

Key Takeaway: If antipsychotics are a significant part of your business, let’s talk. Strategic sourcing can turn them from liability to asset.
