How Brand Manufacturers Produce Their Own Generic Versions

When a brand-name drug’s patent runs out, prices usually drop - sometimes by 80% or more. But here’s the twist: the company that made the original drug often starts selling its own generic version at the same time. This isn’t a loophole. It’s a calculated move called an authorized generic.

What Exactly Is an Authorized Generic?

An authorized generic is the exact same pill, capsule, or injection as the brand-name drug - same active ingredient, same inactive ingredients, same size, same color, same manufacturing process. The only differences? The label says "generic" instead of the brand name, and the packaging is simpler. No reformulation. No shortcuts. It’s the same factory, same equipment, same quality control.

For example, when Pfizer’s Lipitor lost patent protection in 2011, Pfizer didn’t just sit back and watch competitors steal its market. It launched its own authorized generic version the same day. The pill was identical. The only thing changed was the box.

This strategy didn’t start with Lipitor. It began in 1997 when AstraZeneca released an authorized generic of Prilosec, the heartburn drug. Within six months, it captured about 30% of the omeprazole market. Since then, it’s become standard practice. Between 2018 and 2022, 68% of the top 50 brand-name drugs that lost patents had authorized generics introduced by their original makers.

Why Do Brands Make Their Own Generics?

It’s not charity. It’s survival.

Once a patent expires, dozens of other companies can start making the same drug. These generic makers don’t need to repeat expensive clinical trials. They just need to prove their version works the same way. That means prices plummet. The FDA found that in the first year after patent expiry, prices for traditional generics drop by 80-85%.

If the brand manufacturer does nothing, it loses almost all its revenue. But if it launches its own generic? It keeps a slice of the market - often 15-35% - while still controlling production and quality. It’s like opening a discount store next to your own high-end shop and offering the same products at a lower price.

The timing matters too. Under the Hatch-Waxman Act of 1984, the first generic company to file for approval gets 180 days of exclusive rights. But authorized generics don’t count as "first filers." That means the brand manufacturer can enter the market on day one - before the 180-day clock even starts. In 2019, Teva did exactly this with Copaxone, capturing 22% of the generic market in just three months.

How Is It Made? Same Factory, Same Process

There’s no need to build a new plant. The brand manufacturer uses the same facility, the same machines, the same batch records. The only changes are administrative: updating labels, registering a new NDA (Abbreviated New Drug Application), and setting up a separate sales team to avoid regulatory confusion.

The FDA requires no new clinical trials because the manufacturer already has decades of safety and efficacy data. That cuts the approval timeline from an average of 17 months (for traditional generics) to just 6-9 months for authorized generics.

This also means the quality is nearly identical. The FDA reports that authorized generics have a 99.7% bioequivalence rate compared to their brand-name counterparts - higher than many traditional generics.

What’s the Price Difference?

Authorized generics don’t always save you money - at least not as much as you’d expect.

They’re usually priced 10-15% below the brand-name version but 5-10% above competing generics. So if the brand drug costs $100, the authorized generic might be $85, while a regular generic is $75. That’s not a huge discount, and many patients don’t realize they’re getting the same pill.

A 2023 Reddit thread with 147 comments revealed widespread confusion. One user wrote: "I paid $85 for the "generic" version of my medication - then found the real generic for $30. I felt tricked."

But here’s the flip side: patients who know what they’re getting often prefer authorized generics. A Kaiser Family Foundation survey found that 71% of patients chose them when available, citing familiarity. "It’s the same pill I’ve taken for 10 years," one patient wrote on Drugs.com. That trust matters.

Is This Legal? What’s the Controversy?

Yes, it’s legal. But it’s not without criticism.

The Federal Trade Commission (FTC) has accused some companies of using authorized generics as a tool to block competition. In 2017, the FTC sued Actavis over its drug Namenda, claiming the company launched its own generic to scare off other generic makers. The case ended in a $448 million settlement.

Harvard Medical School’s Dr. Aaron Kesselheim argues that authorized generics "provide minimal cost savings to consumers while allowing brand manufacturers to maintain disproportionate market control." His research shows that markets with authorized generics saw only a 32% price drop, compared to 68% in markets with only traditional generics.

But the pharmaceutical industry defends the practice. PhRMA says authorized generics "increase competition and provide consumers with additional lower-cost options while maintaining quality standards." The Congressional Budget Office estimates that authorized generics save $2.3 billion a year in drug spending - but only about 37% of what could be saved if traditional generics dominated the market.

Who Benefits? Who Gets Left Behind?

The biggest winners are the brand manufacturers. They preserve revenue, control supply chains, and avoid the chaos of multiple generic entrants.

Pharmacies and insurers benefit too. Authorized generics are easier to stock - same packaging, same distribution, same reliability. No surprises.

But independent pharmacies and patients who shop for the cheapest option often lose out. A 2022 survey by the National Community Pharmacists Association found that 63% of pharmacists reported confusion among patients. "People think they’re getting a cheaper version, but they’re not," one pharmacist said.

And for smaller generic companies? It’s tough. When a brand manufacturer enters the generic market, it often undercuts them before they even get started. The first generic maker might have spent millions on development, only to see the brand company undercut them on day one.

What’s Next? Biologics and the Future

The trend is growing. Between 2020 and 2023, the top five pharma companies introduced 47 authorized generics - a 28% year-over-year increase.

Now, the strategy is moving into more complex drugs. In 2023, Amgen launched the first authorized biosimilar - a version of its own biologic drug Enbrel. Biosimilars are harder to copy than small-molecule pills. They require advanced manufacturing and years of testing. By launching its own version, Amgen avoids letting competitors enter this high-barrier market.

Analysts at SVB Securities predict that by 2025, 40% of small-molecule drugs losing patents will have authorized generics. For biologics, that number could be even higher.

Companies like Novartis are already planning ahead. With its drug Entresto, they didn’t wait for the patent to expire - they started preparing the authorized generic version years in advance. This "dual launch" strategy turns patent expiration from a threat into a managed transition.

What Should You Do as a Patient?

If you’re on a brand-name drug that’s about to go generic:

• Ask your pharmacist: "Is there an authorized generic available?"
• Compare prices - sometimes the real generic is cheaper.
• If you’re worried about switching, ask if the authorized generic is the same as your current pill - it likely is.
• Don’t assume "generic" means cheaper. Check the price tag.

Most importantly: know that you’re not being tricked. You’re just being sold the same medicine under a different name. And sometimes, that’s exactly what you want.
