Uses

Antibacterial;Bacterial transpeptidase inhibitor

Definition

ChEBI: A penicillin in which the substituent at position 6 of the penam ring is a 2-amino-2-(4-hydroxyphenyl)acetamido group.

brand name

Amoxil (GlaxoSmithKline); Dispermox (Ranbaxy); Larotid (GlaxoSmithKline); Trimox (Apothecon) [Name previously used: Amoxycillin.].

Antimicrobial activity

The antibacterial spectrum is identical to that of ampicillin and there are few differences in antibacterial activity . Like ampicillin, amoxicillin is unstable to most β-lactamases. It has useful activity against Helicobacter pylori (<1% resistance), and is included in most combination regimens for the treatment of H. pylori infections.

Acquired resistance

There is complete cross-resistance with ampicillin. Its action against many β-lactamase-producing strains can be restored by co-administration with β-lactamase inhibitors.

Contact allergens

Amoxicillin is both a topical and a systemic sensitizer. Topical sensitization occurs in health care workers. Systemic drug reactions are frequent, such as urticaria, maculo-papular rashes, baboon syndrome, acute generalized exanthematous pustulosis, or even toxic epidermal necrosis. Cross-reactivity is common with ampicillin, and can occur with other penicillins.

Pharmacokinetics

Oral absorption: 75–90%
Cmax 500 mg oral: 5.5–7.6 mg/L after 1–2 h
500 mg intramuscular: c. 14 mg/L after 1–2 h
Plasma half-life: 1 h
Volume of distribution: 0.3 L/kg
Plasma protein binding: 17–20%
Absorption and distribution
Oral absorption produces over twice the peak concentration achieved by comparable doses of ampicillin, allowing less frequent dosing intervals. Absorption is unaffected by food. It is well-distributed in multiple body fluids, including pleural, peritoneal and middle ear fluid. It does not penetrate well into the CSF.
Metabolism and excretion
Some 10–25% is converted to the penicilloic acid. Between 50% and 70% of unchanged drug is recovered in the urine in the first 6 h after a dose of 250 mg. Plasma levels are elevated and prolonged by the administration of probenecid.

Clinical Use

Amoxicillin, 6-[D-(-)-α-amino-p- hydroxyphenylacetamido]penicillanic acid (Amoxil, Larotid, Polymox), a semisyntheticpenicillin introduced in 1974, is simply the p-hydroxyanalog of ampicillin, prepared by acylation of 6-APA with phydroxyphenylglycine.Its antibacterial spectrum is nearly identical with that ofampicillin, and like ampicillin, it is resistant to acid, susceptibleto alkaline and β-lactamase hydrolysis, andweakly protein bound. Early clinical reports indicated thatorally administered amoxicillin possesses significantadvantages over ampicillin, including more complete GIabsorption to give higher plasma and urine levels, lessdiarrhea, and little or no effect of food on absorption.50Thus, amoxicillin has largely replaced ampicillin for thetreatment of certain systemic and urinary tract infectionsfor which oral administration is desirable. Amoxicillin isreportedly less effective than ampicillin in the treatment ofbacillary dysentery, presumably because of its greater GIabsorption. Considerable evidence suggests that oral absorptionof α-aminobenzyl–substituted penicillins (e.g.,ampicillin and amoxicillin) and cephalosporins is, at leastin part, carrier mediated, thus explaining their generallysuperior oral activity.Amoxicillin is a fine, white to off-white, crystallinepowder that is sparingly soluble in water. It is available invarious oral dosage forms. Aqueous suspensions are stablefor 1 week at room temperature.

Clinical Use

Isolates should be tested for susceptibility before use, especially for serious infections.
Ear, nose and throat infections other than pharyngitis, which may mask glandular fever
Tracheobronchitis, bronchitis, pneumonia
Genitourinary tract infections, including gonorrhea
Infections of skin and soft tissues due to streptococci and susceptible staphylococci
Helicobacter pylori infection (in combination with a proton pump inhibitor and at least one other antimicrobial agent such as clarithromycin)
Prophylaxis of endocarditis in patients undergoing dental treatment and other procedures

Side effects

Amoxicillin is generally well tolerated, side effects being those common to penicillins, but including non-allergic rashes in patients with glandular fever. As the drug is well absorbed, diarrhea is generally infrequent and rarely sufficiently severe to require withdrawal of treatment.
