Cephalosporin brand and generic names
This list uses representative study examples rather than a complete antibiotic formulary. Several recognizable brands are historical: Ceftin, Rocephin, Maxipime, and Omnicef appear in older US references even though their listed brand products have been discontinued. The brand–generic associations remain useful to recognize.
First generation
| Brand name | Generic name | Class or type |
|---|---|---|
| Keflex | cephalexin | 1st-gen cephalosporins |
Second generation
| Brand name | Generic name | Class or type |
|---|---|---|
| Ceftin | cefuroxime axetil | 2nd-gen cephalosporins |
Third generation
| Brand name | Generic name | Class or type |
|---|---|---|
| Omnicef | cefdinir | 3rd-gen cephalosporins |
| Rocephin | ceftriaxone | 3rd-gen cephalosporins |
Fourth generation
| Brand name | Generic name | Class or type |
|---|---|---|
| Maxipime | cefepime | 4th-gen cephalosporins |
Anti-MRSA example, often called fifth generation
| Brand name | Generic name | Class or type |
|---|---|---|
| Teflaro | ceftaroline fosamil | Anti-MRSA cephalosporins |
MRSA means methicillin-resistant Staphylococcus aureus. References may use “anti-MRSA cephalosporins” rather than a fifth-generation heading.
Understanding cephalosporin generations
Generation is a classification shortcut. It does not mean a higher-numbered drug is always better, and it does not make every member of a generation equivalent. For name learning, attach the generation to the specific generic: cephalexin—first; cefuroxime—second; cefdinir and ceftriaxone—third; cefepime—fourth.
Ceftaroline is commonly placed in an anti-MRSA or fifth-generation group. Its product ingredient is ceftaroline fosamil, a prodrug converted to ceftaroline. Retain fosamil when learning the full Teflaro identity, even when a class reference uses the shorter name.
Route and formulation are separate from generation. Cefdinir is an oral example and ceftriaxone an injectable example within the third generation. The generation heading alone cannot tell you how a product is supplied.
Naming patterns and memory tips
Cephalexin shows the ceph- spelling; cefuroxime, cefdinir, ceftriaxone, cefepime, and ceftaroline show cef-. These are family clues. There is no dependable spelling rule that turns the remaining letters into a generation number.
Build a short chain for each example: brand → generic → generation. Begin with Keflex—cephalexin—first generation and Maxipime—cefepime—fourth generation. Add the two third-generation examples together so you do not accidentally learn one drug as the entire generation.
Commonly confused cephalosporin names
Cefdinir and ceftriaxone
Omnicef pairs with cefdinir; Rocephin pairs with ceftriaxone. Both are third generation, so remembering only the generation will not distinguish the two brand pairs.
Cefuroxime and cefuroxime axetil
Ceftin is associated with oral cefuroxime axetil. Cefuroxime also appears in other formulations, so axetil supplies useful product-specific information rather than an extra drug in a combination.
Cephalosporins and penicillins
Both belong to the broader beta-lactam family, but cephalexin is a cephalosporin and amoxicillin is a penicillin. Keep the family hierarchy separate from any assumptions about treatment choice or allergy cross-reactivity.
