Summary--Ru-Vert, a combination product, containing in each tablet, 25 mg of pentylenetetrazol, 12.5 mg of pheniramine maleate, and 50 mg of nictonic acid, was evaluated in the treatment of seventeen patients with benign paroxysmal positional vertigo. The study was double-blind with crossover. Ru-Vert at a dosage of two tablets t.i.d. was found to reduce significantly the nystagmus and the vertigo induced by Hallpike maneuvers in these patients.
