Physical description & handling notes

• Solid
• Sparingly
• Freshly prepared solutions of Meropenem should be used whenever possible. However, constituted solutions of Meropenem maintain satisfactory potency at controlled room temperature 15-25 °C (59-77 °F) or under refrigeration at 4 °C (39 °F) ... . Solutions of intravenous Meropenem should not be frozen.
• Meropenem injection vials constituted with sterile Water for Injection for bolus administration (up to 50 mg/mL of Meropenem) may be stored for up to 2 hours at controlled room temperature 15-25 °C (59-77 °F) or for up to 12 hours at 4 °C (39 °F).
• White to pale yellow crystalline powder. Sparingly soluble in water; very slightly soluble in hydrated ethanol /Meropenem trihydrate/
• The solution varies from colorless to yellow depending on the concentration. The pH of freshly constituted solutions is between 7.3 and 8.3. Meropenem is soluble in 5% monobasic potassium phosphate solution ... and practically insoluble in acetone or ether. /Meropenem trihydrate/
