Therapeutic Class

Antibiotics ( Beta Lactam Anitbiotics)

Dose and Direction of Use

The preparation is strictly for intramuscular injection.

The injection must not be administered into tissue with reduced perfusion.

Benzathine Penicillin should be administered by deep intramuscular injection into the upper, outer quadrant of the gluteus maximus. The puncture should be as vertical to the skin surface as possible and the injection as far away from major vessels as possible. In all events, aspiration must be performed prior to the injection. If aspiration of blood or pain occurs during the injection, it must be discontinued.

For depot preparations, a total volume of 5 ml per injection site is stated as the tolerance limit. Thus, no more than 5 ml of the ready-to-inject suspension should be administered at any one time into one site.

The injection should be given as slowly as possible and only with the application of low pressure. “Rubbing” after the injection should be avoided.

Mode of Action

Penicillin binds to the transpeptidase and interferes with cross-linking of peptidoglycan thus, interfering with the cell wall synthesis. The action is bactericidal and mainly fights and stops the growth of the gram-positive type of bacteria.

Uses

To treat bacterial infections (eg, mild to moderate infections of the upper respiratory tract, syphilis, yaws, bejel, pinta). It is also used to prevent rheumatic fever, chorea, rheumatic heart disease, or acute glomerulonephritis.
