Commonly used solvents include sterile water, bacteriostatic water, or sterile normal saline. Next, you'll use a syringe and needle to draw up the desired volume of solvent from its vial and inject the solvent into the vial of powdered medication.

Sterile water for injection vials are primarily used to reconstitute medications available as lyophilized powders. While the prescribing information for some medications may indicate alternative sterile liquids for reconstitution, most specify that SW for injection must be used.

STEP ONE: Dilute 1 mL (10 mg/mL) of morphine injection with 9 mL of 0.9% sodium chloride (to a total of 10 mL). This makes a 1 mg/mL solution. STEP TWO: Add 1 mL morphine (1 mg/mL) to 24 mL of compatible fluid (to a total of 25 mL). This makes a 40 microgram/mL (0.04 mg/mL) solution.

Reconstitution is the process of adding a liquid diluent to a dry ingredient to make a specific concentration of liquid. See Figure 5.9 for an example of a vial of medication that requires reconstitution.

To reconstitute something is to rebuild it or change the way it's organized. After your club president moves away, you might reconstitute the group by putting the former treasurer in charge and inviting new members to join.

Examples of dry powders mixtures intended for reconstitution to oral solutions are as follows: i) Cloxacillin Sodium for Oral Solution, USP (Teva), an anti-infective antibiotic. ii) Penicillin V Potassium for Oral Solution, USP (Veetids, Geneva), an anti-infective antibiotic.

Using tap water and the measuring cylinder provided, measure out the required volume of water to reconstitute the oral antibiotic powder. Once the correct volume of water is measured, pour it slowly into the medicine bottle containing the oral antibiotic powder.

Add approximately 1/3 of the total amount of water for reconstitution (see Table 2) and shake vigorously to wet powder. Add remainder of the water and again shake vigorously. After reconstitution, the required amount of suspension should be placed directly on the child's tongue for swallowing.

For intramuscular injection, dissolve Ceftriaxone Injection 0.5 g in 2 ml, and Ceftriaxone Injection 1 g in 3.5 ml lidocaine hydrochloride solutions 1% w/v and inject well within the body of a relatively large muscle. It is recommended not to inject more than 1 g at one site.
