Question

The antibiotic streptomycin sulfate is in $5 \mathrm{~g}$ vial of $20 \mathrm{~mL}$ maximum capacity, for veterinary use, and the dry powder accounts for $5 \%$ increase of the final volume of reconstituted solution. Using a 5-g streptomycin sulfate vial and water for injection as a diluent, how would you obtain the antibiotic needed for the following prescription? $\mathrm{R}$ Streptomycin sulfate $1 \mathrm{~g}$ Sodium chloride ad $\quad 100 \mathrm{~mL}$ Sig. For topical use only.

Step 1

The dry powder accounts for a 5% increase in the final volume. Therefore, the final volume $ V_f $ can be calculated as follows: \[ V_f = \frac{20 \, \text{mL}}{1 + 0.05} = \frac{20 \, \text{mL}}{1.05} \approx 19.05 \, \text{mL} \] Show more…
