Drug calculation skills are an important part of prescribing, as calculation errors may lead to significant patient harm. This is particularly important when prescribing for the elderly and paediatric populations, as they are more vulnerable to medication-related harm. Frailty and reduced renal function are commonly seen in the elderly population. ...
When carrying out a drug calculation, there are some basic principlesto keep in mind: 1. Convert all dose units to the same units to avoid confusion 2. Percentage concentrations are expressed as weight/volume (w/v) = 1 g in 100 ml; volume/volume (v/v) = 1 ml in 100 ml; weight/weight (w/w) = 1 g in 100 g; volume/weight (v/w) = 1 ml in 100 g 3. For c...

Adjusted body weight
In clinical practice, the adjusted body weight may be used in obese patients who are >20% of their ideal body weightto prevent overdosing in these patients. This only applies to some medications with poor distribution in adipose tissues, such as aminoglycosides (e.g. gentamicin and amikacin) and varies depending on local guidelines. Resources 1.

Jul 29, 2024 · We must administer 0.1 mg per pound of body weight to a 20 lb child. To calculate how much of the drug should be administered: Dose = Weight × Dosage. Dose = 20 lbs × (0.1 mg / 1 lbs) = 2 mg. To calculate the dose of the syrup: Liquid dose = Dose/Concentration. Liquid dose = 2 mg/(1 mg / 2 mL) = 4 mL.
