Ac Vet Forte D

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.

Dicloxacillin is used for Boils, Carbuncles, Cellulitis, Endocarditis, Folliculitis, Impetigo, Mastitis, Osteomyelitis, Otitis externa, Pneumonia, Septic Arthritis, Staphylococcal skin infections, Streptococcus Septicaemia, Surgical Prophylaxis, Throat infections

How Ac Vet Forte D 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.

Dicloxacillin exerts a bactericidal action against penicillin-susceptible microorganisms during the state of active multiplication. All penicillins inhibit the biosynthesis of the bacterial cell wall. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, dicloxacillin 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 dicloxacillin interferes with an autolysin inhibitor.

Patient with history of allergy esp β-lactam allergy, asthma. Pregnancy and lactation.

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.

Probenecid prolongs serum levels of dicloxacillin. Bacteriostatic drugs (e.g. chloramphenicol, tetracyclines) may antagonise the bactericidal effect of dicloxacillin. May reduce anticoagulant response to dicumarol and warfarin. May increase risk of methotrexate toxicity. May diminish the effect of live vaccines (e.g. typhoid vaccine).

Elimination Route

Absorption of the isoxazolyl penicillins after oral administration is rapid but incomplete: peak blood levels are achieved in 1-1.5 hours. Oral absorption of cloxacillin, dicloxacillin, oxacillin and nafcillin is delayed when the drugs are administered after meals.

Half Life

The elimination half-life for dicloxacillin is about 0.7 hour.

Elimination Route

Ampicillin is excreted largely unchanged in the urine.

Dicloxacillin sodium is rapidly excreted as unchanged drug in the urine by glomerular filtration and active tubular secretion.
