The generic drugs market has become one of the most critical segments in the global healthcare ecosystem, especially in the U.S. As healthcare costs rise and accessibility becomes more urgent, generic drugs offer an affordable alternative to expensive branded medications—while sparking debates on effectiveness, pricing, and investment potential.
In this blog, we’ll explore a generic drugs list with brand names, compare branded vs generic drugs examples, dive into the problems with generic drugs, and even take a look at generic drugs stocks and U.S. generic drug companies shaping the industry in 2025.
What Are Generic Drugs?
Generic drugs are pharmaceutical medications that contain the same active ingredients, dosage form, safety, strength, route of administration, and intended use as their branded counterparts. However, they are sold under their chemical name rather than a brand name—and often at a much lower cost.
Generic Drugs List with Brand Names
Understanding the connection between generic and brand names can help demystify what’s in your medicine cabinet.
Here’s a short list of generic drugs and their brand names:
| Generic Name | Brand Name |
| Atorvastatin | Lipitor |
| Amlodipine | Norvasc |
| Metformin | Glucophage |
| Omeprazole | Prilosec |
| Sertraline | Zoloft |
| Losartan | Cozaar |
| Levothyroxine | Synthroid |
| Fluoxetine | Prozac |
| Albuterol | Ventolin |
| Lisinopril | Prinivil / Zestril |
These generics treat a range of conditions from high cholesterol to diabetes, mental health disorders, and thyroid dysfunction.
Why Do Generic Drugs Cost Less?
One of the most common questions is, why do generic drugs cost less than their branded equivalents?
Here’s why:
- No R&D costs: The original drug manufacturer bears the expense of research, development, and clinical trials. Generic manufacturers don’t.
- No marketing expenses: Generics don’t need million-dollar ad campaigns.
- Competition: Multiple generic manufacturers often produce the same drug, pushing prices lower.
- Patent expiration: Once a brand-name drug’s patent expires (usually after 20 years), generic drug makers can legally produce it.
This leads to savings of 80–90% or more for consumers, without compromising safety or effectiveness.
Branded vs Generic Drugs Examples
Let’s break down branded vs generic drugs examples to clarify their differences and similarities:
Example 1:
- Brand Name: Lipitor
- Generic: Atorvastatin
- Used for: Lowering cholesterol
- Brand Cost: ~$300/month
- Generic Cost: ~$10–$20/month
Example 2:
- Brand Name: Zoloft
- Generic: Sertraline
- Used for: Depression, anxiety
- Brand Cost: ~$100/month
- Generic Cost: ~$5–$15/month
Despite the price gap, both versions deliver the same therapeutic benefit when used correctly.
Problems with Generic Drugs
While generics are largely considered safe and effective, there are some concerns associated with them:
1. Inactive ingredients may differ
These can affect tolerability, especially in patients with allergies or sensitivities.
2. Bioavailability variations
FDA guidelines allow for a small variation (±20%) in bioequivalence, which can affect how the drug is absorbed in the body.
3. Manufacturing standards
Some generics are manufactured overseas in countries with less stringent regulatory oversight, which has raised quality and safety concerns in rare cases.
4. Patient perception
Patients often trust brand names more and may be skeptical about generics, even if medically equivalent.
U.S. Generic Drugs Companies
The United States generic drug market is one of the largest in the world. Leading U.S. generic drugs companies include:
1. Teva Pharmaceuticals (U.S. subsidiary)
One of the largest generic drug makers globally.
2. Amneal Pharmaceuticals
Specializes in complex generics and injectables.
3. Hikma Pharmaceuticals (U.S. branch)
Strong presence in hospitals and retail.
4. Viatris (formed from Mylan and Upjohn)

5. Lannett Company

These companies play a key role in making healthcare affordable and accessible to millions.
