The ideal antihistamine would optimize both receptor and clinical pharmacology, combining high receptor affinity, reflected by high potency, with outstanding clinical efficacy. Because the basic concepts of potency and efficacy are often confused and used interchangeably within the scientific and pharmaceutical industry, the distinction between these 2 terms must be understood in order for them...

Ocular symptoms often accompany allergic rhinitis and can be as or even more bothersome for the patient than the actual nasal symptoms. Ocular manifestations of allergic rhinoconjunctivitis may result from both direct allergen-mediated mast cell stimulation on the surface of the eye and naso-ocular reflexes--histamine being one of the mediators of symptoms onset. An H1 antihistamine would be th...

Objective: We aim to assess the influence of antihistamines as an adjunctive therapy in children with JIA who also have co-existing mild to moderate AR. Methods: Fifty-two JIA patients with AR were enrolled and consecutively randomized. The control group comprised 26 patients who were treated with methotrexate (MTX) 10-15 mg/m2/week orally for 12 months and enteric-coated diclofenac sodium 0.5-...

novel dispersive liquid-liquid microextraction (dllme), coupled with high performance liquid chromatography with photodiode array detection (hplc-dad) has been applied for the extraction and determination of cyproheptadine (cph), an antihistamine, in human urine samples. in this method, 0.6 ml of acetonitrile (disperser solvent) containing 30 µl of carbon tetrachloride (extraction solvent) was ...

Allergic rhinitis is a common disease with a lifetime prevalence of 20% among the United States population. The cost of medication alone to manage allergic rhinitis in the United States was estimated to be $3.1 billion. The two most commonly prescribed classes of medications are antihistamines and topical nasal steroids. The data on comparing the efficacy of a commonly used antihistamine (azela...

BACKGROUND Nose is used as a corridor in endoscopic endonasal transsphenoidal approach (EETSA) for pituitary adenoma. Thus, it may affect the nasal airway patency, function and sinonasal-related quality of life. The aim of this study is to objectively and subjectively evaluate these effects. METHODS In this prospective study, 43 patients with pituitary adenoma who were candidates for EETSA fr...
