PHILOCAINE INJ.

FORTIFIED PROCAINE PENICILLIN FOR INJECTION

I.M. B.P.

This preparation is available in the form of a sterile dry powder containing benzylpenicillin potassium (or sodium) and procaine penicillin with a suitable amount of suspending and buffering agents. The advantage of such a preparation is that it can exert both prompt actions due to the high initial blood levels produced by the soluble potassium salt, and the prolonged action of the insoluble procaine penicillin salt which is adsorbed and excreted slowly. Therefore, a single dose injection of this preparation can maintain an effective concentration in blood for 12-24 hours.

Action and uses:

It has the same indications as penicillin. As its peak blood concentration is relatively low, it is only indicated in mild infections caused by penicillin-sensitive bacteria, such as tonsillitis, scarlet fever, erysipelas, furuncles, and carbuncles. It is also effective for syphilis, Vincent’s angina, and gonorrhea.

Administration and dosage:

It is given by I.M. injection only. A suitable amount of water for injection is added to the vial before use. 400,000 i.u.-800,000 i.u. each time, once or twice a day.

Caution:

1. Before administration skin tests of procaine and penicillin should be made. It should not be administrated to patients hypersensitive to penicillin and procaine.
2. The suspension prepared by adding a suitable amount of water for injection into the vial should be stored below 10°C and used up within 24 hours.
