    Area of Science:

    • Pharmacology
    • Clinical Pharmacy
    • Drug Delivery Systems

    Background:

    • Accurate drug dosage calculation is critical for patient safety.
    • Manual calculations for intravenous infusions can be time-consuming and prone to errors.
    • Existing methods may not be easily adaptable for precise microgram per kilogram per minute dosing.

    Purpose of the Study:

    • To develop a simplified and accurate method for calculating drug infusion dosages.
    • To establish a protocol for achieving precise microgram per kilogram per minute drug delivery.
    • To reduce the risk of calculation errors in clinical practice.

    Main Methods:

    • A straightforward multiplication factor (15) was introduced.
    • Patient weight in kilograms is multiplied by this factor to determine milligrams of drug.

  • The calculated drug amount is added to 250 ml of infusate vehicle.
  • A microdrip chamber (60 drops/ml) is utilized for administration.

    • Main Results:

    • The proposed method simplifies the calculation of drug infusion dosages.
    • The resulting solution delivers 1 microgram per kilogram per minute per drop.
    • Dosage can be precisely controlled by setting the infusion rate (1 drop = 1 microgram/kg).

    Conclusions:

    • This simplified method enhances accuracy and efficiency in drug infusion calculations.
    • It provides a practical approach for achieving precise therapeutic drug levels.
    • The method is particularly useful for microgram per kilogram per minute dosing regimens.
