How much sterile, non-bacteriostatic water is required to mix with a 20mg vial of Dantrolene?

1. 30 cc's

2. 40 cc's

3. 50 cc's

4. 60 cc's

The correct answer is: 60 cc's

To determine the correct volume of sterile, non-bacteriostatic water required to mix with a 20 mg vial of Dantrolene, it is important to understand the manufacturer's recommended dilution criteria. Dantrolene is typically reconstituted with sterile water prior to administration because it is a powdered medication that requires mixing to prepare the correct dosage for injection. In practice, the recommended dosage for reconstituting Dantrolene requires a specific amount of diluent. For a 20 mg vial, the appropriate volume is often detailed in guidance materials or product inserts, which recommend using 60 cc (or mL) of sterile, non-bacteriostatic water. This amount ensures that the solution is adequately mixed, achieving the proper concentration for administration, while also allowing for easier withdrawal of the medication from the vial. Using 60 cc of water provides sufficient volume to adequately dissolve the powder, while also making it easier for healthcare professionals to withdraw a precise dose of the medication for patient treatment. It's critical that the guidelines provided by the manufacturer are followed to ensure patient safety and therapeutic effectiveness.
