split dosing
Administration of daily medication in divided doses rather than single daily dose to improve therapeutic coverage.
Full Definition
Split dosing involves dividing a patient's total daily medication dose into two or more administrations throughout the day. In methadone treatment, split dosing may be used for patients experiencing withdrawal symptoms between doses due to rapid metabolism or other factors. This practice requires careful evaluation, as it increases clinic burden and diversion risk, but may improve treatment retention and patient comfort for appropriate candidates.
Usage
Usage note: Hyphenate as adjective; distinguish from dose splitting for take-homes.
