In changing an overseas diabetic patient from U-80 to U-100 Insulin, a pharmacist needs to determine the equivalent quantity. How may ml of U-100 is required if the previous dosage was 0.5ml of U-80 Insulin per day?
Accepted Answer
The equivalent quantity of U-100 insulin is 0.4mL. Here's the calculation:
U-80 insulin: This means there are 80 units of insulin per 1 mL of solution.
U-100 insulin: This means there are 100 units of insulin per 1 mL of solution.
To maintain the same dosage, we need to figure out how much U-100 insulin contains the same number of units as 0.5mL of U-80 insulin:
Units in 0.5mL of U-80: 0.5mL
80 units/mL = 40 units
Volume of U-100 insulin containing 40 units: 40 units / 100 units/mL = 0.4mL
