Ampicillin inhibits bacterial cell wall synthesis by binding to 1 or more of the penicillin-binding proteins (PBPs) which in turn inhibit the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.

Ampicillin is a penicillin beta-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually gram-positive, organisms. The name "penicillin" can either refer to several variants of penicillin available, or to the group of antibiotics derived from the penicillins. Ampicillin has in vitro activity against gram-positive and gram-negative aerobic and anaerobic bacteria. The bactericidal activity of Ampicillin results from the inhibition of cell wall synthesis and is mediated through Ampicillin binding to penicillin binding proteins (PBPs). Ampicillin is stable against hydrolysis by a variety of beta-lactamases, including penicillinases, and cephalosporinases and extended spectrum beta-lactamases.

Cloxacillin inhibits bacterial cell wall synthesis by binding to 1 or more of the penicillin-binding proteins (PBPs) which in turn inhibit the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.

Cloxacillin is a semisynthetic antibiotic in the same class as penicillin. Cloxacillin is for use against staphylococci that produce beta-lactamase.

Uses

Ampicillin is used for the treatment of infections caused by susceptible strains of the designated organism listed below:

  • Infections of the Genitourinary Tract Including Gonorrhea: E. coli, P. mirabilis, enterococci, Shigella, S. typhosa and other Salmonella, and nonpenicillinase-producing N. gononhoeae.
  • Infections of the Respiratory Tract: Nonpenicillinase-producing H. influenzae and staphylococci, and streptococci including streptococcus pneumoniae.
  • Infections of the Gastrointestinal Tract: Shigella, S. typhosa and other Salmonella, E. coli, P. mirabilis, and enterococci.
  • Meningitis: O. Meningitides.

Bacteriology studies to determine the causative organisms and their sensetivity to ampicillin should be performed. Therapy may be instituted prior to the results of susceptibility testing.

Cloxacillin is used for the treatment of infections caused by Grampositive organisms including infections caused by β-lactamase producing Staphylococci such as :

  • Skin and soft tissue infections : Boils, Abscesses, Carbuncles, Furunculosis, Cellulitis, Infected wounds, Infected burns, Otitis media and externa, Protection of skin graft and Skin infections like ulcer, eczema, acne, etc.
  • Respiratory tract infections : Pneumonia, Lung abscess, Empyema, Sinusitis, Pharyngitis and Tonsillitis.
  • Other infections caused by sensitive organisms : Osteomyelitis, Enteritis, Endocarditis, Urinary tract infection, Meningitis and Septicaemia.

How Adaclox works

By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, Ampicillin inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that Ampicillin interferes with an autolysin inhibitor.

Interaction

May reduce the efficacy of oral contraceptives. May alter INR while on warfarin and phenindione. May reduce the efficacy of oral typhoid vaccines. May reduce the excretion of methotrexate. Reduced excretion with probenecid and sulfinpyrazone, resulting to increased risk of toxicity. Allopurinol increases ampicillin-induced skin reactions. Reduced absorption with chloroquine. Bacteriostatic antibacterials (e.g. erythromycin, chloramphenicol, tetracycline) may interfere with the bactericidal action of ampicillin.

May diminish the effect of BCG and typhoid vaccine. May increase risk of methotrexate toxicity. May diminish the therapeutic effect of Na picosulfate. May decrease serum concentrations of mycophenolate. May prolong bleeding time with anticoagulants. Increased serum concentrations with probenecid. Tetracycline may antagonise the bactericidal effect of cloxacillin.
