Amoxicillin; Amoxycillin; (2S,5R,6R)-6-[[(2R)-2-amino-2-(4-hydroxyphenyl)acetyl]amino]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid (IUPAC) · Amoxicillin, Amoxycillin, Amox; trade names include Amoxil, Moxatag, Trimox (and as the trihydrate in most oral formulations)

Modern MM

A modern drug remedy whose sphere of action mirrors the documented toxicology of the antibiotic: gastrointestinal (diarrhoea, nausea, vomiting), the skin (allergic urticaria and delayed maculopapular drug eruptions), and mucous membranes prone to candidal overgrowth. There is no proving-derived constitutional or mental picture.

Key symptoms

No keynotes from a formal proving are on record. The fact-based indications inferred from amoxicillin's toxicology (Law of Similars) are: itching urticarial rash and angio-oedema after drug exposure; flat, red, often non-itchy maculopapular ('amoxicillin') rash; antibiotic-associated diarrhoea, nausea and vomiting (including C. difficile diarrhoea); and candidal overgrowth of mucous membranes (oral thrush, vaginal thrush) following antibiotic use. These are pharmacological/clinical associations, not proven keynotes.

Worse (aggravation)

No proving-derived modalities exist. Not established.

Better (amelioration)

Source & Nature

AMOXICILLINUM is the homeopathic preparation of amoxicillin (amoxycillin), a semi-synthetic aminopenicillin beta-lactam antibiotic, molecular formula C16H19N3O5S, MW ~365.40 g/mol anhydrous (CAS 26787-78-0; PubChem CID 33613). The commonly dispensed trihydrate is C16H25N3O8S (CAS 61336-70-7). Introduced clinically by Beecham around 1974, amoxicillin is a bactericidal inhibitor of bacterial cell-wall synthesis (binds penicillin-binding proteins, blocking transpeptidation) and is one of the most widely prescribed oral antibiotics worldwide.
