Clinical studies of terfenadine in seasonal allergic rhinitis. 1982

M L Brandon, and M Weiner

alpha-[4-(1,1-Dimethylethyl)phenyl]-4-(hydroxydiphenylmethyl)-1- piperidinebutanol (terfenadine, RMI 9918, Triludan, Teldane, resp.) was evaluated in groups of at least 30 patients per drug for relief of symptoms of active allergic pollinosis on a double-blind basis during the pollen season for 3 successive years. Terfenadine 20 mg 3 times a day was as effective as chlorpheniramine maleate 4 mg 3 times a day. In each study chlorpheniramine consistently showed a higher incidence of sedation than placebo. None of the terfenadine dosage schedules up to 200 mg 3 times a day caused sedation significantly different from that of placebo or efficacy greater than that seen with 20 mg 3 times a day. The incidence of central nervous system stimulation in the terfenadine group was also not different from that of placebo.

D006255	Rhinitis, Allergic, Seasonal	Allergic rhinitis that occurs at the same time every year. It is characterized by acute CONJUNCTIVITIS with lacrimation and ITCHING, and regarded as an allergic condition triggered by specific ALLERGENS.

D006634	Histamine H1 Antagonists	Drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine. Included here are the classical antihistaminics that antagonize or prevent the action of histamine mainly in immediate hypersensitivity. They act in the bronchi, capillaries, and some other smooth muscles, and are used to prevent or allay motion sickness, seasonal rhinitis, and allergic dermatitis and to induce somnolence. The effects of blocking central nervous system H1 receptors are not as well understood.

D016593	Terfenadine	A selective histamine H1-receptor antagonist devoid of central nervous system depressant activity. The drug was used for ALLERGY but withdrawn due to causing LONG QT SYNDROME.
