Doosis

Doo sis is a term used in pharmacology and clinical planning to describe the structured process of determining and administering drug doses to achieve a balance between efficacy and safety. It encompasses selecting an initial dose, deciding on maintenance dosing, dosing intervals, and routes of administration, as well as adjustments based on patient response and tolerability. The concept emphasizes tailoring regimens to individual factors rather than applying fixed, one-size-fits-all schedules.

Etymology and usage: The term is not standardized in medical dictionaries and has no universally agreed-upon definition. It appears as a hybrid of "dose" and the suffix -osis, indicating a process. In many discussions, doosis is presented as a framework rather than a rigid protocol, used to illustrate the dynamic nature of dosing in real-world care.

Core components: Dosing strategies typically integrate pharmacokinetic and pharmacodynamic considerations, therapeutic drug monitoring, and patient-specific variables such as age, body weight, organ function, comorbidities, and drug interactions. Models may include loading doses, maintenance doses, and interval modifications, with adjustments guided by measured drug levels, clinical response, and adverse effects.

Applications and limitations: Doosis is discussed in clinical pharmacology, oncology, and antimicrobial stewardship as a way to conceptualize personalized dosing. It is less common in formal guidelines and not universally adopted, which can lead to confusion with conventional dosage terminology. Practitioners should interpret the term as a heuristic rather than a standardized protocol.
