MDC Pharmacokinetics (PK) II Practice Exam

Which antibiotic is supplied by Cathay Drug?

Cloxacillin (Oxaclen) Amoxicillin (Pediamox) Cefaclor (Ceclor) Benzylpenicillin

Correct Answer:

Benzylpenicillin

Explanation:

The question tests familiarity with which antibiotic a supplier stocks. Cathay Drug is known in many practice references for supplying benzylpenicillin (penicillin G) preparations for injection. Among the options, this is the classic injectable penicillin that matches Cathay Drug’s product line. The other drugs belong to different families or forms—cloxacillin is a penicillinase-resistant penicillin, amoxicillin is an oral amino-penicillin, and cefaclor is a cephalosporin—so they don’t align with Cathay Drug’s typical listing.
