Concurrent use of probenecid with ampicillin and sulbactam for injection may result in increased and prolonged blood levels of ampicillin and sulbactam. 365 0 obj <> endobj

Top Answer. The corresponding mean peak serum levels for sulbactam range from 48 to 88 mcg/mL and 21 to 40 mcg/mL, respectively. dose is 110mg. Reconstituted solution should be diluted further in 0.9% sodium chloride (normal saline) to yield a concentration between 3 and 45 mg/mL (ampicillin sodium 2 to 30 mg/mL and sulbactam sodium 1 to 15 mg/mL).

It's that old "dose ordered divided by the concentration available= amount to be given " calculation. I'm thinking that if the med in the vial is 250mg ,its 250mg regardless of how many mls the mixed volumn is. Answer: The procedures for reconstituting medications is highly scrutinized by the Food and Drug Administration (FDA). allnurses is Registered ® Copyright © allnurses.com

(Ampicillin is, however, degraded by beta-lactamases and therefore the spectrum of activity does not normally include organisms which produce these enzymes. Call the doc and ask him if he really wanted 260mg!! I'm thinking about Rocephin, once mixed its 2.1mls that is given to get the total mg dosage.
