Doositulemus

Doositulemus is a term used in pharmacology and toxicology to denote the observed outcome or effect produced by a given administered dose of a drug or toxin. The word combines Estonian roots doosi meaning dose and tulemus meaning result or outcome, and is used to describe the dose–effect relationship in both therapeutic and adverse contexts. In practice, doositulemus refers to the measured response across dose levels in preclinical experiments and clinical trials, and serves as the basis for dose–response modeling.

The concept encompasses potency, expressed as the dose required to achieve a specified effect (for example ED50), and efficacy, the maximum effect attainable. It can be described by standard models such as logistic or Hill equations, which characterize how the doositulemus changes with dose, including thresholds, slope, and saturation. Factors influencing doositulemus include pharmacokinetics (absorption, distribution, metabolism, excretion), pharmacodynamics (receptor interactions, signaling pathways), and patient-specific variables (age, genetics, comorbidities).

Doositulemus is central to determining dosing guidelines, therapeutic windows, and safety margins. It supports comparisons across formulations, routes of administration, or populations and is used to assess both beneficial effects and adverse effects. In reporting, researchers often present dose–response curves, along with quantitative parameters such as ED50, EC50, TD50, and the maximum tolerated dose.
