Authorized Generics vs Regular Generics: What's the Difference?
Authorized generics are made by the brand-name manufacturer itself, while regular generics come from independent companies. Here is how they differ in quality, price, and availability.
Two Types of Generic Drugs
When a brand-name drug loses patent protection, you will typically see two types of generic versions appear on pharmacy shelves: authorized generics and regular (independent) generics. Both are safe and effective, but they differ in origin, pricing, and availability.
Understanding the difference can help you make smarter choices when filling prescriptions.
What Is an Authorized Generic?
An authorized generic is a generic drug that is produced or licensed by the brand-name manufacturer itself. It is typically the exact same pill — same factory, same formulation, same everything — just sold under a generic name at a lower price.
Example
The brand-name drug Lipitor (atorvastatin) is made by Pfizer. Pfizer also produces an authorized generic version of atorvastatin. It is the same pill in different packaging at a lower price.
What Is a Regular Generic?
A regular generic is produced by an independent generic manufacturer such as Apotex, Teva, or Sandoz. These companies develop their own formulation of the drug, submit it to Health Canada for approval through the ANDS process, and manufacture it in their own facilities.
Key Differences
| Factor | Authorized Generic | Regular Generic |
|---|---|---|
| Manufacturer | Brand-name company | Independent generic company |
| Formulation | Identical to brand name | Same active ingredient, may differ in fillers |
| Manufacturing facility | Same as brand name | Different facility |
| Health Canada approval | Marketed under brand's DIN or separate DIN | Separate ANDS submission |
| Price | Slightly higher than regular generics | Usually the lowest price |
| Availability | Often first to market | May take longer to reach pharmacies |
Quality Comparison
Are Authorized Generics Higher Quality?
No. Both authorized and regular generics meet the same Health Canada standards. The perception that authorized generics are "better" comes from the fact that they are made by the brand-name company, but this does not translate to any clinical advantage.
Health Canada requires all generics — authorized or independent — to demonstrate bioequivalence to the reference product. The testing standards are identical.
When Might It Matter?
For the vast majority of medications, there is no meaningful difference between authorized and regular generics. However, for narrow therapeutic index drugs (like warfarin or levothyroxine), some patients prefer to stay with one manufacturer — whether that is the authorized generic or a specific regular generic — to maintain consistency.
Price Comparison
Authorized generics are typically priced between the brand name and regular generics:
| Version | Typical Pricing (relative) |
|---|---|
| Brand name | 100% (reference price) |
| Authorized generic | 40 - 60% of brand price |
| Regular generic | 20 - 35% of brand price |
Real-World Example: Atorvastatin (90-day supply)
| Version | Approximate Cost |
|---|---|
| Lipitor (brand) | $180 |
| Authorized generic (Pfizer) | $65 - $85 |
| Regular generic (Apotex/Teva) | $28 - $42 |
Why Do Brand Companies Sell Authorized Generics?
It seems counterintuitive — why would a brand-name company compete with itself? There are several strategic reasons:
How to Choose Between Them
For Most Medications
Choose the cheapest option, which is usually a regular generic from Apotex, Teva, or Sandoz. The savings over an authorized generic can be $20 to $50 per 90-day supply.
For Narrow Therapeutic Index Drugs
Pick one version — authorized or regular — and stick with it. Consistency matters more than which specific generic you choose.
For First-Time Generic Users
If you are anxious about switching from brand to generic, an authorized generic can be a comfortable first step since it is the same pill. Once you see it works the same way, you can switch to a cheaper regular generic at your next refill.
The Bottom Line
Both authorized and regular generics are safe, effective, and approved by Health Canada. For most Canadians, the regular generic offers the best value. Check TransparentMedz to see all available versions of your medication and their prices at pharmacies in your area.
