Pharmacology and toxicology:
Mechanism of action:
Adco-Amoclav is a combination of amoxicillin and potassium clavulanate. The amoxicillin component of the
formulation exerts a bactericidal action against many strains of Gram positive and Gram-negative organisms.
The clavulanic acid component has little or no antimicrobial action. However, by inactivation of susceptible
beta-lactamase protect amoxicillin from degradation by beta-lactamase enzymes produced by penicillin
resistant strains of organisms.
Clavulanic acid is an irreversible inhibitor of beta-lactamases produced by Staphylococcus aureus,
Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis and Proteus vulgaris , H. influenzae, N.
gonorrhoeae and B. fragilis( In-vitroactivity does not necessarily imply in-vivo efficacy). Potassium clavulanate
does not inactivate the chromosomally mediated (Cephalosporinase) beta-lactamases produced by Acineto
bacter species, Citrobacter species,Enterobacter, indole positive Proteus, Providencia species and Serratia
The pharmacokinetics of amoxicillin and clavulanic acid are closely allied and neither are adversely affected
by the presence of food in the stomach, and are stable in the presence of gastric acid. The oral bioavailability
of amoxicillin and potassium clavulante is approximately 90% and 75% respectively.
Peak serum levels of both occur about 1-2 hour after oral administration. Clavulanic acid has about the same
plasma elimination half-life (1 hour) as that of amoxicillin (1,3 hours). Adco-Amoclav Suspension is eliminated
primarily unchanged through the renal route (glomerularfiltration and tubular secretion). Approximately 50-78%
of amoxicillin and 25-40% of clavulanic acid are excreted unchanged in urine within the first 6 hrs after
SIDE EFFECTS AND SPECIAL PRECAUTIONS:
Sensitivity reactions are more likely to occur in individuals who have previously demonstrated hypersensitivity
to penicillins and in those with a history of allergy, asthma, hay fever or urticaria.The hypersensitivity reactions
reported are erythematous maculopapular rashes, fever and joint pains. Anaphylactic shock may occur.
Nausea, heartburn, vomiting and diarrhoea.
Pseudomembranous colitis has been reported.
Hepatotoxicity, hepatitis, cholestatic jaundice may occur. A moderate rise in serum glutamic oxalacetic
transaminase (SGOT) has been noted, but the significance of this finding is unknown.
Hemic and Lymphatic Systems
Anaemia, thrombocytopenia, thrombocytopenic purpura, eosinophilia, leukopenia and granulocytopenia have
been reported during therapy with Adco-Amoclav. These reactions are usually reversible on discontinuation
of therapy and are believed to be hypersensitivity phenomena.
Central Nervous System
Reversible hyperactivity, agitation, anxiety, insomnia, confusion, behavioural changes, and/or dizziness have
also been reported. Depression, seizures, or hallucinations.
Other A sore mouth or tongue and a black hairy tongue have been reported.
Allergic reactions which may include exfoliative dermatitis, other skin rashes, interstitial nephritis and
vasculitis, may occur. Erythema multiforme (including Stevens Johnson syndrome), toxic episodes of
