Answer:
The duration of treatment with amoxicillin should last for 10 days, according to the prescription.
Explanation:
The duration in days of a treatment with amoxicillin, according to a physician's prescription, depends on the concentration of the medicine and the amount available in the bottle.
- Dose: 250 mg
- Interval between doses: TID = every 8 hours
- Concentration: 125 mg/5 ml
- Volume of medicine in the bottle: 300 ml
Each dose involves administering 10 ml of the drug, so in one day 30 cc will be used.
- Individual dose = 125 mg x 2 = 250mg
- Total daily dose = 250 mg X 3
- Total daily dose = 750 mg
If the drug has a concentration of 125 mg in 5 ml, 750 mg is equivalent to 30 ml:
125 mg ------------------- 5 ml
750 mg ------------------- X
X = (750 mg x 5) / 125
X = 30 ml.
This is the total volume of amoxicillin that can be administered per day.
Dividing the total amount of medicine by the daily volume administered gives the number of days the treatment lasts.
<u>Days of treatment = 300 ml / 30 ml/day = 10 days</u>
