Non sedating antihistamines urticaria treatment studies on online dating

In addition, patients were excluded if they met any criteria from a typical list of exclusion criteria for pharmacological studies: presence of a permanent gastrointestinal condition that may influence oral therapy, history or presence of epilepsy, significant neurological disorders, cerebrovascular attacks or ischaemia, history or presence of myocardial infarction or cardiac arrhythmia that requires drug therapy, evidence of severe renal dysfunction, evidence of significant hepatic disease, presence of active cancer that requires chemotherapy, presence of alcohol abuse or drug addiction, participation in any clinical trial within 4 weeks prior to enrolment, pregnancy or breast-feeding, and existing or planned placement in an institution after ruling according to § 40 AMG (Arzneimittelgesetz). This was considered sufficient to adequately investigate the objectives of this study, based upon the investigator’s experience and previous studies on urticaria.

Formally, our study had a power of 80% to detect effects of size 1.085 (quotient difference of means and standard deviation). At visit 1, screening for eligibility was performed, and patients were requested to stop taking any antihistamines for the duration of the study, if possible.

Symptoms of 29 patients with chronic spontaneous urticaria were followed without treat­ment on one day and again on another day during the next 3 weeks after a single dose of either 5 mg or 20 mg desloratadine, using different objective measures.

While the intervention with both doses of desloratadine was effective in terms of a reduction in hyperthermic skin area, there was no improvement in wheal area and wheal volume compared with no treatment.

-antihistamines are the recommended first-line treatment for chronic spontaneous urticaria.

The current guidelines for management of urticaria strongly recommend non-sedating H-antihistamines (ns AH) as the first-line symptomatic treatment for CSU, based on a large body of high-quality evidence (7).Most clinical trials rely on patient assessments of symptoms and quality of life over a period of outpatient treatment time.Although this is entirely appropriate, we designed the current clinical study to examine the efficacy of standard dose desloratadine (5 mg) and up-dosed desloratadine (20 mg) on existing wheals, under carefully monitored conditions, using the most technically reliable, objective measures.It is characterized by a recurrent and spontaneous appearance of itchy wheals with or without angioedema, for 6 weeks or longer (1, 2).CSU often lasts for years, sometimes even decades, and has a substantial impact on patients’ quality of life (3–5).
