Amoxicillin vs. Penicillin — What's the Difference?

Amoxicillin is a broad-spectrum antibiotic.

Penicillin is the original antibiotic.

Amoxicillin treats various bacterial infections.

Penicillin can cause allergies.

Amoxicillin is a derivative of Penicillin.

Penicillin is less acid-stable.

Amoxicillin is orally administered.

Penicillin is often injected.

Amoxicillin is more acid-stable.

Penicillin has a narrower spectrum.

Amoxicillin is an antibiotic used to treat a number of bacterial infections. These include middle ear infection, strep throat, pneumonia, skin infections, and urinary tract infections among others.

Penicillins (P, PCN or PEN) are a group of antibiotics originally obtained from Penicillium moulds, principally P. chrysogenum and P. rubens. Most penicillins in clinical use are chemically synthesised from naturally-produced penicillins.

A semisynthetic penicillin, C16H19N3O5S, having an antibacterial spectrum of action similar to that of ampicillin.

An antibiotic drug obtained from molds especially of the genus Penicillium or produced synthetically, available in various preparations and usually used to treat infections caused by gram-positive bacteria.

(pharmaceutical drug) A moderate-spectrum, bacteriolytic beta-lactam antibiotic C₁₆H₁₉N₃O₅S closely related to ampicillin and with similar properties, but more readily absorbed when taken orally. It is used to treat bacterial infections caused by susceptible microorganisms.

Any of a group of broad-spectrum antibiotic drugs, synthetic or semisynthetic, that are derived from penicillin.

An antibiotic; a semisynthetic oral penicillin (trade names Amoxil and Larotid and Polymox and Trimox and Augmentin) used to treat bacterial infections

(pharmaceutical drug) Any of a group of narrow-spectrum antibiotics obtained from Penicillium molds or synthesized, that have a beta-lactam structure and are active against gram-positive bacteria and used in the treatment of various infections and diseases.

(mycology) A blue mold of the genus Penicillium that produces penicillin.

Any of a variety of substances having a structure containing a beta-lactam ring fused to a thiirane ring, to which a carboxyl group is attached, but most commonly interpreted as benzyl penicillin. They are notable as powerful antibacterial agents of relatively low toxicity which have found extensive use in medicine for treating bacterial infections. They are categorized as one of the classes of beta-lactam antibiotic. They are produced naturally by some fungi and bacteria, and industrial production processes almost invariably start from some form of the penicillin nucleus produced by fermentation of microorganisms. The fermentation products are then chemically modified to produce derivatives of enhanced potency, safety, or antibacterial spectrum. The first penicillin to see extensive use clinically (during World War II) was penicillin G, also called benzypenicillin, and commonly simply "penicillin".

Any of various antibiotics obtained from penicillium molds (or produced synthetically) and used in the treatment of various infections and diseases
