Twenty patients of mean age 41.3 years, with a diagnosis of chronic idiopathic urticaria were assessed in a fully randomized, double-blind, crossover study to investigate the efficacy of acrivastine at two doses (8 mg and 4 mg) versus 1 mg clemastine and placebo, given three times per day. All active preparations were found to be effective, and significantly better than placebo, in controlling the signs and symptoms of urticaria. There was a higher incidence of sedation with clemastine than with either acrivastine or placebo, although this difference did not achieve statistical significance in this small study.

D010919	Placebos	Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol.	Sham Treatment
D011725	Pyridines	Compounds with a six membered aromatic ring containing NITROGEN. The saturated version is PIPERIDINES.
D011759	Pyrrolidines	Compounds also known as tetrahydropyridines with general molecular formula (CH2)4NH.	Tetrahydropyridine,Tetrahydropyridines
D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).
