20. BPPVに対する薬物療法
Medications — Medications are not useful for the brief episodes of
vertigo associated with BPPV, except when the frequency of spells is
very high [52]. However, vestibular suppressants can be used as
premedication with liberatory maneuvers, and may help patients who
would not otherwise tolerate these maneuvers because of discomfort
and nausea. In a randomized trial, patients given betahistine (24 mg
twice daily for one week) along with the Epley maneuver had reduced
dizziness symptoms compared with those treated with the maneuver
alone
