Other Information
Gadopentetate dimeglumineInjection is the N-methylglucamine salt of the gadolinium complex of diethylenetriamine pentaacetic acid, and is an injectable contrast medium for magnetic resonance imaging (MRI). Gadopentetate dimeglumine Injection is provided as a sterile, clear, colorless to slightly yellow aqueous solution for intravenous injection.
Gadopentetate dimeglumine Injection is a 0.5- mol/L solution of 1-deoxy-1-(methylamino)-D-glucitol dihydrogen [N,N-bis[2-[bis(carboxymethyl)amino]ethyl]- glycinato (5-)]gadolinate(2--) (2:1) with a molecular weight of 938, an empirical formula of C28H54GdN5O20, and has the following structural formula:
Each mL contains 469.01 mg gadopentetate dimeglumine, 0.99 mg meglumine, 0.40 mg diethylenetriamine pentaacetic acid and water for injection. Gadopentetate dimeglumine Injection contains no antimicrobial preservative.
Gadopentetate dimeglumine Injection has a pH of 6.5 to 8.0. Pertinent physicochemical data are noted below:

*Rate of injection: 10 mL/15 sec
Drug Handling:To ensure complete injection of the contrast medium, the injection should be followed by a 5-mL normal saline flush. The imaging procedure should be completed within 1 hour of injection of Gadopentetate dimeglumine Injection.
As with other gadolinium contrast agents, Gadopentetate dimeglumine Injection has not been established for use in magnetic resonance angiography.
Parenteral products should be inspected visually for particulate matter and discoloration prior to administration. Do not use the solution if it is discolored or particulate matter is present.
Pharmacy Bulk Package Preparation: NOT FOR DIRECT INFUSIONThe Pharmacy Bulk Package is used as a multiple dose container with an appropriate transfer device for filling empty sterile syringes.
a) The transfer of Gadopentetate dimeglumine Injection from the Pharmacy Bulk Package must be performed in an aseptic work area, such as a laminar flow hood, using aseptic technique.
b) Once the Pharmacy Bulk Package is punctured, it should not be removed from the aseptic work area during the entire 24 hour period of use.
c) The contents of the Pharmacy Bulk Package after initial puncture should be used within 24 hours.
d) Any unused Gadopentetate dimeglumine Injection must be discarded 24 hours after the initial puncture of the bulk package.
IV tubing and syringes used to administer Gadopentetate dimeglumine Injection must be discarded at the conclusion of the radiological examination.
Any unused portion must be discarded in accordance with regulations dealing with the disposal of such materials.
