Which two drugs are classified as aminopenicillins?

Aminopenicillins are a subclass of penicillin antibiotics that are specifically characterized by their ability to treat a broader spectrum of bacterial infections compared to natural penicillins. They are particularly effective against certain gram-negative bacteria due to their extended usability against penicillin-sensitive strains.

Ampicillin and Amoxicillin are two well-known examples of aminopenicillins. They have a similar core structure to penicillin but are modified to enhance their efficacy against a wider range of bacteria. Ampicillin is often used in the treatment of infections such as respiratory tract infections and urinary tract infections, while Amoxicillin is frequently prescribed for similar conditions as well as for its convenience in dosing and better gastrointestinal absorption.

In contrast, the other drug choices refer to different classes or generations of penicillins. Cloxacillin and Dicloxacillin are classified as penicillinase-resistant penicillins, primarily effective against staphylococci. Piperacillin and Ticarcillin are classified as extended-spectrum penicillins, designed to target more resistant gram-negative bacteria. Benzathine and Procaine Penicillin refer to formulations of penicillin that are used for specific purposes, such as long-acting treatments, rather than being aminopen
