CLAMENTIN is the group name for formulations containing 2, 4 and 5 parts of a broad spectrum penicillin, amoxycillin and 1 part of potassium clavulanate. Potassium clavulanate has been shown in vitro to be an irreversible inhibitor of beta-lactamases produced by; Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Proteus vulgaris, Haemophilus influenzae, Neisseria gonorrhoeae and Bacteroides fragilis. Potassium clavulanate does not inactivate the chromosomally mediated (Sykes Type 1 Cephalosporinase) beta-lactamases produced by Acinetobacter species, Citrobacter species, Enterobacter, Indole positive Proteus, Providencia species and Serratia marcescens. In vitro the formulation showed synergism against amoxycillin-resistant organisms, with no evidence of antagonism and the activity was not reduced in the presence of serum.
(In vitro activity does not necessarily imply in vivo efficacy).
|(ii) Bactericidal action:|
The amoxycillin component of the formulations exert a bactericidal action against many strains of Gram-positive and Gram-negative organisms. The clavulanic acid component has very little bactericidal action. It does however, by inactivation of susceptible beta-lactamases, protect amoxycillin from degradation by a large number of beta-lactamase enzymes produced by penicillin resistant strains of organisms.
