INDICATIONS AND USAGE
Ampicillin and sulbactam for injection, USP is indicated for the treatment of infections due to susceptible strains of the designated microorganisms in the conditions listed below. Skin and Skin Structure Infections caused by beta-lactamase producing strains of Staphylococcus aureus , Escherichia coli ,• Klebsiella spp.• (including K. pneumoniae •), Proteus mirabilis ,• Bacteroides fragilis ,• Enterobacter spp.,• and Acinetobacter calcoaceticus .• NOTE: For information on use in pediatric patients (see PRECAUTIONS–Pediatric Use and CLINICAL STUDIES sections). Intra-Abdominal Infections caused by beta-lactamase producing strains of Escherichia coli , Klebsiella spp. (including K. pneumoniae •), Bacteroides spp. (including B. fragilis ), and Enterobacter spp.• Gynecological Infections caused by beta-lactamase producing strains of Escherichia coli ,• and Bacteroides spp.• (including B. fragilis •). • Efficacy for this organism in this organ system was studied in fewer than 10 infections. While ampicillin and sulbactam for injection, USP is indicated only for the conditions listed above, infections caused by ampicillin-susceptible organisms are also amenable to treatment with ampicillin and sulbactam for injection, USP due to its ampicillin content. Therefore, mixed infections caused by ampicillin-susceptible organisms and beta-lactamase producing organisms susceptible to ampicillin and sulbactam for injection, USP should not require the addition of another antibacterial. Appropriate culture and susceptibility tests should be performed before treatment in order to isolate and identify the organisms causing infection and to determine their susceptibility to ampicillin and sulbactam for injection, USP. Therapy may be instituted prior to obtaining the results from bacteriological and susceptibility studies when there is reason to believe the infection may involve any of the beta-lactamase producing organisms listed above in the indicated organ systems. Once the results are known, therapy should be adjusted if appropriate. To reduce the development of drug-resistant bacteria and maintain effectiveness of ampicillin and sulbactam for injection, USP and other antibacterial drugs, ampicillin and sulbactam for injection, USP should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
DOSAGE AND ADMINISTRATION
The pharmacy bulk package is for preparation of solutions for IV infusion only. Ampicillin and sulbactam for injection should be administered by slow intravenous injection over at least 10 to 15 minutes or can also be delivered in greater dilutions with 50 to 100 mL of a compatible diluent as an intravenous infusion over 15 to 30 minutes. The recommended adult dosage of ampicillin and sulbactam for injection is 1.5 g (1 g ampicillin as the sodium salt plus 0.5 g sulbactam as the sodium salt) to 3 g (2 g ampicillin as the sodium salt plus 1 g sulbactam as the sodium salt) every six hours. This 1.5 to 3 g range represents the total of ampicillin content plus the sulbactam content of ampicillin and sulbactam for injection, and corresponds to a range of 1 g ampicillin/0.5 g sulbactam to 2 g ampicillin/1 g sulbactam. The total dose of sulbactam should not exceed 4 grams per day. Pediatric Patients 1 Year of Age or Older The recommended daily dose of ampicillin and sulbactam for injection in pediatric patients is 300 mg per kg of body weight administered via intravenous infusion in equally divided doses every 6 hours. This 300 mg/kg/day dosage represents the total ampicillin content plus the sulbactam content of ampicillin and sulbactam for injection, and corresponds to 200 mg ampicillin/100 mg sulbactam per kg per day. The safety and efficacy of ampicillin and sulbactam for injection administered via intramuscular injection in pediatric patients have not been established. Pediatric patients weighing 40 kg or more should be dosed according to adult recommendations, and the total dose of sulbactam should not exceed 4 grams per day. The course of intravenous therapy should not routinely exceed 14 days. In clinical trials, most children received a course of oral antimicrobials following initial treatment with intravenous ampicillin and sulbactam for injection. (see CLINICAL STUDIES section). Impaired Renal Function In patients with impairment of renal function the elimination kinetics of ampicillin and sulbactam are similarly affected, hence the ratio of one to the other will remain constant whatever the renal function. The dose of ampicillin and sulbactam in such patients should be administered less frequently in accordance with the usual practice for ampicillin and according to the following recommendations:
| Creatinine Clearance (mL/min/1.73 m 2 ) | Ampicillin/Sulbactam Half-Life (Hours) | Recommended Ampicillin and Sulbactam for Injection Dosage |
|---|---|---|
| ≥30 | 1 | 1.5 to 3 g q 6h to q 8h |
| 15 to 29 | 5 | 1.5 to 3 g q 12h |
| 5 to 14 | 9 | 1.5 to 3 g q 24h |
When only serum creatinine is available, the following formula (based on sex, weight, and age of the patient) may be used to convert this value into creatinine clearance. The serum creatinine should represent a steady state of renal function. Males weight (kg) × (140 – age) 72 × serum creatinine Females 0.85 × above value
COMPATIBILITY, RECONSTITUTION AND STABILITY
When concomitant therapy with aminoglycosides is indicated, ampicillin and sulbactam and aminoglycosides should be reconstituted and administered separately, due to the in vitro inactivation of aminoglycosides by any of the aminopenicillins.
DIRECTIONS FOR USE
Intravenous Administration Directions for Proper Use of Pharmacy Bulk Package Ampicillin and sulbactam for injection sterile powder for intravenous use may be reconstituted with any of the compatible diluents described in this insert. Solutions should be allowed to stand after dissolution to allow any foaming to dissipate in order to permit visual inspection for complete solubilization. Ampicillin and sulbactam for injection concentrations between 3 and 45 mg (2 to 30 mg ampicillin/1 to 15 mg sulbactam/mL) are recommended for intravenous use. The 15 gram bottle may be reconstituted with either 92 mL Sterile Water for Injection or 0.9% Sodium Chloride Injection. The diluent should be added in two separate aliquots in a suitable work area, such as a laminar flow hood. Add 50 mL of solution, shake to dissolve. Then add an additional 42 mL and shake. The solution should be allowed to stand after dissolution to allow any foaming to dissipate in order to permit visual inspection for complete solubilization. The resultant solution will have a final concentration of approximately 100 mg/mL ampicillin and 50 mg/mL sulbactam. The closure may be penetrated only one time after reconstitution, if needed, using a suitable sterile transfer device or dispensing set that allows for measured dispensing of the contents. After reconstitution, use within two hours if stored at room temperature, or within four hours if stored under refrigeration.
| Reconstituted Bulk Solution Should Not be Used For Direct Infusion |
If the reconstituted bulk solution is stored for less than one hour at room temperature (20°C/68°F) prior to further dilution, the use periods indicated in Table 4 apply for the diluted solutions. If the bulk solution is stored for one to two hours at room temperature (20°C/68°F) and then diluted with Sterile Water for Injection or 0.9% Sodium Chloride Injection to the following concentrations, the use periods indicated in Table 5 apply. Any unused portions of solution that remain after the indicated time periods should be discarded.

Urinalysis: Presence of RBC’s and hyaline casts in urine.
Postmarketing Experience In addition to adverse reactions reported from clinical trials, the following have been identified during post-marketing use of ampicillin sodium/sulbactam sodium or other products containing ampicillin. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of their seriousness, frequency, or potential causal connection to ampicillin sodium/sulbactam sodium.
Blood and Lymphatic System Disorders: Hemolytic anemia, thrombocytopenic purpura, and agranulocytosis have been reported. These reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena.

Drug Interactions
Probenecid decreases the renal tubular secretion of ampicillin and sulbactam. Concurrent use of probenecid with ampicillin and sulbactam may result in increased and prolonged blood levels of ampicillin and sulbactam. The concurrent administration of allopurinol and ampicillin increases substantially the incidence of rashes in patients receiving both drugs as compared to patients receiving ampicillin alone. It is not known whether this potentiation of ampicillin rashes is due to allopurinol or the hyperuricemia present in these patients. There are no data with ampicillin and sulbactam and allopurinol administered concurrently. Ampicillin and sulbactam and aminoglycosides should not be reconstituted together due to the in vitro inactivation of aminoglycosides by the ampicillin component of ampicillin and sulbactam.
DESCRIPTION
Ampicillin and sulbactam for injection, USP is an injectable antibacterial combination consisting of the semisynthetic antibacterial ampicillin sodium and the beta-lactamase inhibitor sulbactam sodium for intravenous and intramuscular administration. HOWEVER, THE INTENT OF THE PHARMACY BULK PACKAGE IS FOR PREPARATION OF SOLUTIONS FOR IV INFUSION ONLY. Ampicillin sodium is derived from the penicillin nucleus, 6-aminopenicillanic acid. Chemically, it 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 and has a molecular weight of 371.39. Its chemical formula is C 16 H 18 N 3 NaO 4 S. The structural formula is:
Sulbactam sodium is a derivative of the basic penicillin nucleus. Chemically, sulbactam sodium is sodium penicillinate sulfone; sodium (2S, 5R)-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo [3.2.0] heptane-2-carboxylate 4,4-dioxide. Its chemical formula is C 8 H 10 NNaO 5 S with a molecular weight of 255.22. The structural formula is:
Ampicillin and sulbactam for injection parenteral combination, is available as a white to off-white, crystalline powder for reconstitution. Ampicillin and sulbactam for injection crystalline powder is freely soluble in aqueous diluents to yield pale yellow to yellow solutions containing ampicillin sodium and sulbactam sodium equivalent to 250 mg ampicillin per mL and 125 mg sulbactam per mL. The pH of the solutions is between 8 and 10. Dilute solutions (up to 30 mg ampicillin and 15 mg sulbactam per mL) are essentially colorless to pale yellow. The pH of dilute solutions remains the same. Each sterile Pharmacy Bulk Package contains 15 g ampicillin and sulbactam for injection (10 g ampicillin as the sodium salt plus 5 g sulbactam as the sodium salt) and approximately 1150 mg (50 mEq) sodium. Ampicillin and sulbactam for injection Pharmacy Bulk Package is a bottle containing a sterile preparation of ampicillin sodium and sulbactam sodium for parenteral use that contains many single doses. The Pharmacy Bulk Package is for use in a pharmacy admixture setting; it provides many single doses of ampicillin and sulbactam for addition to suitable parenteral fluids in the preparation of admixtures for intravenous infusion (see DIRECTIONS FOR PROPER USE OF PHARMACY BULK PACKAGE ). FURTHER DILUTION IS REQUIRED BEFORE USE.
CLINICAL PHARMACOLOGY
General
Immediately after completion of a 15-minute intravenous infusion of ampicillin and sulbactam for injection, peak serum concentrations of ampicillin and sulbactam are attained. Ampicillin serum levels are similar to those produced by the administration of equivalent amounts of ampicillin alone. Peak ampicillin serum levels ranging from 109 to 150 mcg/mL are attained after administration of 2,000 mg of ampicillin plus 1,000 mg sulbactam and 40 to 71 mcg/mL after administration of 1,000 mg ampicillin plus 500 mg sulbactam. The corresponding mean peak serum levels for sulbactam range from 48 to 88 mcg/mL and 21 to 40 mcg/mL, respectively. After an intramuscular injection of 1,000 mg ampicillin plus 500 mg sulbactam, peak ampicillin serum levels ranging from 8 to 37 mcg/mL and peak sulbactam serum levels ranging from 6 to 24 mcg/mL are attained. The mean serum half-life of both drugs is approximately 1 hour in healthy volunteers. Approximately 75 to 85% of both ampicillin and sulbactam are excreted unchanged in the urine during the first 8 hours after administration of ampicillin and sulbactam for injection to individuals with normal renal function. Somewhat higher and more prolonged serum levels of ampicillin and sulbactam can be achieved with the concurrent administration of probenecid. In patients with impaired renal function the elimination kinetics of ampicillin and sulbactam are similarly affected, hence the ratio of one to the other will remain constant whatever the renal function. The dose of ampicillin and sulbactam for injection in such patients should be administered less frequently in accordance with the usual practice for ampicillin (see DOSAGE and ADMINISTRATION section). Ampicillin has been found to be approximately 28% reversibly bound to human serum protein and sulbactam approximately 38% reversibly bound. The following average levels of ampicillin and sulbactam were measured in the tissues and fluids listed:
| Fluid or Tissue | Dose (grams) Ampicillin/Sulbactam | Concentration (mcg/mL or mcg/g) Ampicillin/Sulbactam |
|---|---|---|
| Peritoneal Fluid | 0.5/0.5 IV | 7/14 |
| Blister Fluid (Cantharides) | 0.5/0.5 IV | 8/20 |
| Tissue Fluid | 1/0.5 IV | 8/4 |
| Intestinal Mucosa | 0.5/0.5 IV | 11/18 |
| Appendix | 2/1 IV | 3/40 |
Penetration of both ampicillin and sulbactam into cerebrospinal fluid in the presence of inflamed meninges has been demonstrated after IV administration of ampicillin and sulbactam. The pharmacokinetics of ampicillin and sulbactam in pediatric patients receiving ampicillin and sulbactam are similar to those observed in adults. Immediately after a 15-minute infusion of 50 to 75 mg ampicillin and sulbactam/kg body weight, peak serum and plasma concentrations of 82 to 446 mcg ampicillin/mL and 44 to 203 mcg sulbactam/mL were obtained. Mean half-life values were approximately 1 hour.
MICROBIOLOGY
Ampicillin is similar to benzyl penicillin in its bactericidal action against susceptible organisms during the stage of active multiplication. It acts through the inhibition of cell wall mucopeptide biosynthesis. Ampicillin has a broad spectrum of bactericidal activity against many gram-positive and gram-negative aerobic and anaerobic bacteria. (Ampicillin is, however, degraded by beta-lactamases and therefore the spectrum of activity does not normally include organisms which produce these enzymes). A wide range of beta-lactamases found in microorganisms resistant to penicillins and cephalosporins have been shown in biochemical studies with cell free bacterial systems to be irreversibly inhibited by sulbactam. Although sulbactam alone possesses little useful antibacterial activity except against the Neisseriaceae , whole organism studies have shown that sulbactam restores ampicillin activity against beta-lactamase producing strains. In particular, sulbactam has good inhibitory activity against the clinically important plasmid mediated beta-lactamases most frequently responsible for transferred drug resistance. Sulbactam has no effect on the activity of ampicillin against ampicillin susceptible strains. The presence of sulbactam in the ampicillin and sulbactam for injection formulation effectively extends the antibacterial spectrum of ampicillin to include many bacteria normally resistant to it and to other beta-lactam antibacterials. Thus, ampicillin and sulbactam for injection possesses the properties of a broad-spectrum antibacterial and a beta-lactamase inhibitor. While in vitro studies have demonstrated the susceptibility of most strains of the following organisms, clinical efficacy for infections other than those included in the INDICATIONS AND USAGE section has not been documented. Gram-Positive Bacteria Staphylococcus aureus (beta-lactamase and non-beta-lactamase producing), Staphylococcus epidermidis (beta-lactamase and non-beta-lactamase producing), Staphylococcus saprophyticus (beta-lactamase and non-beta-lactamase producing), Streptococcus faecalis † (Enterococcus), Streptococcus pneumoniae † (formerly D. pneumoniae ), Streptococcus pyogenes † , Streptococcus viridans † . Gram-Negative Bacteria Hemophilus influenzae (beta-lactamase and non-beta-lactamase producing), Moraxella (Branhamella) catarrhalis (beta-lactamase and non-beta-lactamase producing), Escherichia coli (beta-lactamase and non-beta-lactamase producing), Klebsiella species (all known strains are beta-lactamase producing), Proteus mirabilis (beta-lactamase and non-beta-lactamase producing), Proteus vulgaris , Providencia rettgeri , Providencia stuartii , Morganella morganii , and Neisseria gonorrhoeae (beta-lactamase and non-beta-lactamase producing). Anaerobes Clostridium species † , Peptococcus species † , Peptostreptococcus species, Bacteroides species, including B. fragilis . † These are not beta-lactamase producing strains and, therefore, are susceptible to ampicillin alone. Susceptibility Testing For specific information regarding susceptibility test interpretive criteria and associated test methods and quality control standards recognized by FDA for this drug, please see: https://www.fda.gov/STIC.
CLINICAL STUDIES
Skin and Skin Structure Infections in Pediatric Patients Data from a controlled clinical trial conducted in pediatric patients provided evidence supporting the safety and efficacy of ampicillin and sulbactam for injection for the treatment of skin and skin structure infections. Of 99 pediatric patients evaluable for clinical efficacy, 60 patients received a regimen containing intravenous ampicillin and sulbactam, and 39 patients received a regimen containing intravenous cefuroxime. This trial demonstrated similar outcomes (assessed at an appropriate interval after discontinuation of all antimicrobial therapy) for ampicillin and sulbactam- and cefuroxime-treated patients:
| Therapeutic Regimen | Clinical Success | Clinical Failure |
|---|---|---|
| Ampicillin and Sulbactam | 51/60 (85%) | 9/60 (15%) |
| Cefuroxime | 34/39 (87%) | 5/39 (13%) |
Most patients received a course of oral antimicrobials following initial treatment with intravenous administration of parenteral antimicrobials. The study protocol required that the following three criteria be met prior to transition from intravenous to oral antimicrobial therapy: (1) receipt of a minimum of 72 hours of intravenous therapy; (2) no documented fever for prior 24 hours; and (3) improvement or resolution of the signs and symptoms of infection. The choice of oral antimicrobial agent used in this trial was determined by susceptibility testing of the original pathogen, if isolated, to oral agents available. The course of oral antimicrobial therapy should not routinely exceed 14 days.
