Amoxicillin is a broad spectrum aminopenicillin antibiotic belonging to the beta lactam family. It is used to treat infections caused by susceptible bacteria and has established activity against a range of Gram positive and selected Gram negative organisms.
Amoxicillin works by interfering with bacterial cell wall synthesis. It binds to penicillin binding proteins involved in producing the peptidoglycan structure that gives bacterial cell walls their strength. Inhibition of this process weakens the cell wall and ultimately causes susceptible bacteria to rupture and die, making amoxicillin a bactericidal antibiotic.
Amoxicillin is commonly used for susceptible ear, nose and throat infections, lower respiratory tract infections, genitourinary infections, and skin and soft tissue infections. Depending on the organism and clinical setting, susceptible bacteria can include Streptococcus pneumoniae, other Streptococcus species, Enterococcus faecalis, Haemophilus influenzae, Escherichia coli, and Proteus mirabilis.
Amoxicillin is also used as part of certain combination treatment regimens for Helicobacter pylori (H. pylori) infection associated with duodenal ulcer disease. The exact combination of medications and treatment duration should be determined by a healthcare professional.

Amoxicillin is relatively stable in stomach acid and is readily absorbed following oral administration. A substantial portion of the absorbed medication is eliminated unchanged through the kidneys and urine, making renal function an important consideration in some patients.
An important limitation of amoxicillin is bacterial resistance. Many resistant organisms produce beta lactamase enzymes capable of breaking open the beta lactam structure of amoxicillin and rendering the antibiotic ineffective. Susceptibility testing and local resistance patterns may therefore be important when selecting antibiotic therapy.
As with other penicillin antibiotics, amoxicillin can cause allergic and hypersensitivity reactions, including potentially severe anaphylactic reactions in susceptible individuals. Patients with a history of serious reactions to penicillin or related beta lactam antibiotics should discuss this with a healthcare professional before treatment.
Common adverse effects can include nausea, diarrhea, vomiting, and skin rash. Antibiotic treatment can also disrupt normal intestinal bacteria and may contribute to Clostridioides difficile associated diarrhea, which can range from mild gastrointestinal symptoms to serious colitis.
Amoxicillin should be used only for infections that are proven or strongly suspected to be bacterial. Unnecessary antibiotic use can contribute to antimicrobial resistance and reduce the effectiveness of antibiotics when they are genuinely required.
Amoxicillin is a prescription antibiotic and should be taken according to the directions of a qualified healthcare professional.
