Is cefaclor a “second-generation” cephalosporin?
Cefaclor is a second-generation cephalosporin antibiotic. It belongs to the oral cephalosporin class and is commonly characterized as a “second-generation” agent in standard drug references. [1][2]
What is the most authoritative way to cite cefaclor’s generation/class?
For authoritative, search-ready classification, use a standard clinical drug monograph (e.g., FDA labeling or a peer-reviewed/medical reference such as Medscape) that explicitly lists the drug as a second-generation cephalosporin. Credible sources that describe cefaclor’s class/generation include:
- Medscape drug monograph for cefaclor [1]
- DrugBank (classification commonly reflects “second-generation cephalosporin”) [2]
FDA label: what does it say about cefaclor?
The U.S. FDA label is the primary regulatory document for cefaclor’s approved indications and labeling claims. If you specifically need a “generation” statement, many FDA labels focus on indications/dosing/contraindications and may not always use the “second-generation” wording in the same way medical references do. For that reason, clinicians often pair FDA labeling (for approved use) with a clinical monograph (for class/generation language). [3]
What counts as “authoritative source” for drug classification searches?
For “authoritative source” purposes, the strongest options are:
- FDA drug label (official U.S. regulatory document) [3]
- Major clinical drug monographs (e.g., Medscape) [1]
- Well-regarded drug databases that explicitly state generation/class (e.g., DrugBank) [2]
If you need citations for a paper or guideline
Use two layers of support: cite FDA labeling for approved status/indications and cite a clinical monograph or drug database for the “second-generation” classification wording. This gives both regulatory authority and explicit generation labeling. [1][3]
