Dosvolym

Dosvolym is a Swedish term that denotes the volume of a dose administered. It describes how much liquid or solution is given per dosing event and is typically expressed in milliliters (ml) or cubic centimeters (cc). In clinical practice and pharmacology, dosvolym is determined from the prescribed dose and the preparation’s concentration.

In practice, dosvolym is calculated as the required dose divided by the concentration of the preparation. For liquids, dose volume equals the amount of active substance (in mg or µg) divided by the preparation’s concentration (mg/ml). For vaccines and other ready-to-use liquids, the label usually specifies both the dose and the corresponding volume to be administered. In inhalation therapy, dosvolym may refer to the volume delivered per puff or per inhalation.

Contexts where the term is used include human medicine, veterinary medicine, and laboratory research. Healthcare professionals use calibrated devices such as syringes, droppers, or metered-dose inhalers to ensure accurate dosvolym. The emphasis on volume rather than mass is common when the concentration can vary between preparations or batches.

Safety and accuracy are central concerns: an incorrect dosvolym can lead to underdosage or overdose. Verification against the prescribing information and consideration of patient factors (such as age and weight) are essential, particularly in pediatric care where precise measurement is crucial.
