Rocastine (AHR-11325) is a potent, nonsedating antihistamine with a rapid onset of action. This H1-antagonist effectively protected guinea pigs challenged with a lethal dose of histamine. It has also been mentioned in patents as a candidate to treat eye conditions and cough/cold mixtures (in which the lack of sedative effects from a non-sedating antihistamine would be especially useful in children, because daytime sedation is especially undesirable in this group). However, information on current use is not available and other second-generation, non-sedative antihistamines are available.
