In patients with decreased kidney function, the dosing frequency may need to be reduced.Reported adverse events include both local and systemic reactions. Local adverse reactions are characterized by redness, tenderness, and soreness of the skin at the injection site. The mean peak ampicillin and sulbactam serum concentrations following intravenous dosing were 170.3 and 87.5 micrograms/mL, respectively. Symptoms of allergic reactions may range from rash to potentially life-threatening conditions, such as anaphylaxis. The pharmacokinetics of this antibiotic combination were determined in patients receiving continuous ambulatory peritoneal dialysis (CAPD). 1996 Oct;31(4):293-308. doi: 10.2165/00003088-199631040-00005.Johnson CA, Ateshkadi A, Zimmerman SW, Hughes GS, Craig WA, Carey PM, Borin MT.Antimicrob Agents Chemother. 1, and changes in CFU per gram over 72 h are detailed in Table 2.Ampicillin monotherapy was bactericidal against W04 and W07 but was bacteriostatic against W151. 1993 Dec;37(12):2650-5. doi: 10.1128/aac.37.12.2650. New York, NY: McGraw-Hill; 2014.Unasyn. Pharmacodynamics. The mean peak serum concentrations of ampicillin and sulbactam following intraperitoneal dosing were 48.0 and 27.8 micrograms/mL, respectively. Clipboard, Search History, and several other advanced features are temporarily unavailable. The pharmacodynamic activity of this drug was also determined by use of mean bactericidal titers against selected bacterial strains. Chapter 88. 2016 Sep 10;36(5):481-508. doi: 10.3747/pdi.2016.00078. Spectrum of activity includes non-penicillinase-producing gram-positive bacteria. DynaMed Web Site. Available at: UNASYN [package insert]. Patients who have asthma, eczema, hives, or hay fever are more likely to develop undesirable reactions to any of the penicillins.Pamphlet Pfizer. In pediatric patients, the dose is based on body weight and is recommended at 300 mg per kilogram of body weight per day. Pharmacodynamics of Antibiotics in Bone Cornelia B. Landersdorfer, Jürgen B. Bulitta, and Fritz Sörgel Chronic osteomyelitis requires prolonged antibiotic treatment, has a high recurrence rate, and can cause irreversible damage. Pharmacodynamics. The pharmacokinetics of this antibiotic combination were determined in patients receiving continuous ambulatory peritoneal dialysis (CAPD). It is effective against certain gram positive bacteria, gram-negative bacteria, and anaerobe.Ampicillin-sulbactam only comes in a parenteral formulation to be either used as intravenous or intramuscular injections, and can be formulated for intravenous infusion.→Brand names: Unasyn, Unasyn ADD-Vantage, Unasyn Piggyback Ampicillin sodium is derived from the basic penicillin nucleus, 6-aminopenicillanic acid. This total daily dose is to be divided into equal amounts to be given every six hours. CLSI document M02-A11. Ampicillin is a time-dependent antibiotic with its bacterial killing largely dependent on the time the free concentration is maintained above the MIC during a dosing interval (fT> MIC). Skin and Soft-Tissue Infections. Performance Standards for Antimicrobial Disk Diffusion Susceptibility Tests; Approved Standard – 11th ed. The fixed combination antibiotic ampicillin/sulbactam may provide a new, safe, and effective method of treating dialysis-related bacterial peritonitis. →Brand names: Unasyn, Unasyn ADD-Vantage, Unasyn Piggyback It has been reported to occur in 16% of patients receiving intramuscular injections, and 3% of patients receiving intravenous injections. Epub 2016 Jun 9.Taylor CA 3rd, Abdel-Rahman E, Zimmerman SW, Johnson CA.Clin Pharmacokinet. The duration of exposure will therefore determine the rate and extent of bacterial killing. CLSI, 950 West Valley Rd., Suite 2500, Wayne, PA 19087, 2012.Clinical and Laboratory Standards Institute (CLSI). Pifzer Inc., New York, NY; April 2007. This increases the antimicrobial activity by 4- to 32-fold when compared to ampicillin alone.Ampicillin/sulbactam has poor absorption when given orally.Ampicillin/sulbactam is a combination of a β-lactam antibiotic and a β-lactamase inhibitor. Both drugs exhibited similar distribution and elimination characteristics. Its chemical name is monosodium (2S, 5R, 6R)-6-[(R)-2-amino-2-phenylacetamido]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylate. Absolute bioavailabilities of the intraperitoneal ampicillin and sulbactam doses were 60% and 68%. Ampicillin/sulbactam is a combination of the common penicillin-derived antibiotic ampicillin and sulbactam, an inhibitor of bacterial beta-lactamase.Two different forms of the drug exist.
