Drug calculation Drug calculation is the process of determining the correct dose of medication for a patient based on factors such as their weight, age, medical history, and other relevant factors. This is an important process to ensure that patients receive the appropriate amount of medication for their needs and to minimize the risk of adverse reactions or medication errors. Drug calculations may involve various types of measurements, including volume (such as milliliters), weight (such as milligrams or grams), and concentration (such as a percentage or ratio of active ingredient to total volume). The calculation process typically involves converting between these different units of measurement, as well as accounting for any adjustments needed based on the patient's individual characteristics or medical condition. There are various methods and tools that can be used to perform drug calculations, including calculators, conversion tables, and formulas. It is important for healt
