Daptomycin (Page 2 of 10)
2.6 Dosage in Patients with Renal Impairment
Adult Patients
No dosage adjustment is required in adult patients with creatinine clearance (CLCR ) greater than or equal to 30 mL/min. The recommended dosage regimen for daptomycin for injection in adult patients with CLCR less than 30 mL/min, including adult patients on hemodialysis or continuous ambulatory peritoneal dialysis (CAPD), is 4 mg/kg (cSSSI) or 6 mg/kg (S. aureus bloodstream infections) once every 48 hours (Table 3). When possible, daptomycin for injection should be administered following the completion of hemodialysis on hemodialysis days [see Warnings and Precautions (5.2, 5.10), Use in Specific Populations (8.6), and Clinical Pharmacology (12.3)].
| Creatinine Clearance (CL CR ) | Dosage Regimen in Adults | |
|---|---|---|
| *When possible, administer daptomycin for injection following the completion of hemodialysis on hemodialysis days. | ||
| cSSSI | S. aureus Bloodstream Infections | |
| Greater than or equal to 30 mL/min | 4 mg/kg once every 24 hours | 6 mg/kg once every 24 hours |
| Less than 30 mL/min, including hemodialysis and CAPD | 4 mg/kg once every 48 hours* | 6 mg/kg once every 48 hours* |
Pediatric Patients
The dosage regimen for daptomycin for injection in pediatric patients with renal impairment has not been established.
2.7 Preparation and Administration of Daptomycin for Injection
There are other formulations of daptomycin that have differences concerning reconstitution and storage. Carefully follow the reconstitution and storage procedures described in this labeling.
Reconstitution of Daptomycin for Injection Vial
Daptomycin for injection is supplied in single-dose vials, each containing 500 mg daptomycin as a sterile, lyophilized powder. The contents of a daptomycin for injection vial should be reconstituted, using aseptic technique, to 50 mg per mL as follows:
- To minimize foaming, AVOID vigorous agitation or shaking of the vial during or after reconstitution.
- Remove the polypropylene flip-off cap from the daptomycin for injection vial to expose the central portion of the rubber stopper.
- Wipe the top of the rubber stopper with an alcohol swab or other antiseptic solution and allow to dry. After cleaning, do not touch the rubber stopper or allow it to touch any other surface.
- Slowly transfer 10 mL of 0.9% sodium chloride injection through the center of the rubber stopper into the daptomycin for injection vial, pointing the transfer needle toward the wall of the vial. It is recommended that a beveled sterile transfer needle that is 21 gauge or smaller in diameter, or a needleless device is used, pointing the transfer needle toward the wall of the vial.
- Ensure that all of the daptomycin for injection powder is wetted by gently rotating the vial.
- Allow the wetted product to stand undisturbed for 10 minutes.
- Gently rotate or swirl the vial contents for a few minutes, as needed, to obtain a completely reconstituted solution.
Administration Instructions
Parenteral drug products should be inspected visually for particulate matter prior to administration.
Slowly remove reconstituted liquid (50 mg daptomycin per mL) from the vial using a beveled sterile needle that is 21 gauge or smaller in diameter. Administer as an intravenous injection or infusion as described below:
Adults
Intravenous Injection over a period of 2 minutes
- For intravenous (IV) injection over a period of 2 minutes in adult patients only: Administer the appropriate volume of the reconstituted daptomycin for injection (concentration of 50 mg per mL).
Intravenous Infusion over a period of 30 minutes
- For intravenous (IV) infusion over a period of 30 minutes in adult patients: The appropriate volume of the reconstituted daptomycin for injection (concentration of 50 mg per mL) should be further diluted, using aseptic technique, into a 50 mL IV infusion bag containing 0.9% sodium chloride injection.
Pediatric Patients (1 to 17 Years of Age)
Intravenous Infusion over a period of 30 or 60 minutes
- Unlike in Adults, do NOT administer Daptomycin for Injection by injection over a two (2) minute period to pediatric patients [see Dosage and Administration (2.1)].
- For Intravenous infusion over a period of 60 minutes in pediatric patients 1 to 6 years of age: The appropriate volume of the reconstituted daptomycin for injection (concentration of 50 mg per mL) should be further diluted, using aseptic technique, into an intravenous infusion bag containing 25 mL of 0.9% sodium chloride injection. The infusion rate should be maintained at 0.42 mL/minute over the 60-minute period.
- For Intravenous infusion over a period of 30 minutes in pediatric patients 7 to 17 years of age: The appropriate volume of the reconstituted daptomycin for injection (concentration of 50 mg per mL) should be further diluted, using aseptic technique, into a 50 mL IV infusion bag containing 0.9% sodium chloride injection. The infusion rate should be maintained at 1.67 mL/minute over the 30-minute period.
No preservative or bacteriostatic agent is present in this product. Aseptic technique must be used in the preparation of final IV solution. Do not exceed the In-Use storage conditions of the reconstituted and diluted solutions of daptomycin for injection described below. Discard unused portions of daptomycin for injection.
In-Use Storage Conditions for Daptomycin for Injection Once Reconstituted in Acceptable Intravenous Diluents
Stability studies have shown that the reconstituted solution is stable in the vial for 12 hours at room temperature and up to 48 hours if stored under refrigeration between 2° and 8°C (36° and 46°F).
The diluted solution is stable in the infusion bag for 12 hours at room temperature and 48 hours if stored under refrigeration. The combined storage time (reconstituted solution in vial and diluted solution in infusion bag) should not exceed 12 hours at room temperature or 48 hours under refrigeration.
2.8 Compatible Intravenous Solutions
Daptomycin for injection is compatible with 0.9% sodium chloride injection and Lactated Ringer’s injection.
2.9 Incompatibilities
Daptomycin for injection is not compatible with dextrose-containing diluents.
Daptomycin for injection should not be used in conjunction with ReadyMED® elastomeric infusion pumps. Stability studies of daptomycin for injection solutions stored in ReadyMED® elastomeric infusion pumps identified an impurity (2-mercaptobenzothiazole) leaching from this pump system into the daptomycin for injection solution.
Because only limited data are available on the compatibility of daptomycin for injection with other IV substances, additives and other medications should not be added to daptomycin for injection single-dose vials or infusion bags, or infused simultaneously with daptomycin for injection through the same IV line. If the same IV line is used for sequential infusion of different drugs, the line should be flushed with a compatible intravenous solution before and after infusion with daptomycin for injection.
