Effects on growth and tolerance and hypoallergenicity of an amino acid-based formula with synbiotics.

Background: To evaluate the effects of an amino acid-based formula (AAF) with synbiotics on growth and tolerance in healthy infants. The hypoallergenicity of this AAF with synbiotics was evaluated in subjects with cow's milk allergy (CMA).

Methods: Study 1: 115 full-term, healthy infants randomly received an AAF with synbiotics or a commercially available AAF for 16 wk.

The concept of receptor occupancy to predict clinical efficacy: a comparison of second generation H1 antihistamines.

Second generation H1 antihistamines are considered first-line therapy for allergic rhinitis and chronic idiopathic urticaria, largely because of their nonsedating effects. Evaluating pharmacokinetic and pharmacodynamic parameters and clinical efficacy of a drug is important, but models to predict clinical efficacy are lacking. Receptor occupancy (RO), a predictor for human pharmacodynamics and antihistamine potency that takes into account the affinity of the drug for the receptor and its free plasma concentration, may be a more accurate way to predict a drug's clinical efficacy.

Efficacy of fexofenadine versus desloratadine in suppressing histamine-induced wheal and flare.

To date, no published articles exist comparing the H1-receptor antagonist activities of fexofenadine and desloratadine using the histamine-induced skin wheal-and-flare model. The aim of this study was to compare the efficacy of fexofenadine versus desloratadine in suppressing histamine-induced skin flares and wheals in adults and adolescents. This was a two-center, randomized, placebo-controlled, complete-crossover study.

The health-related quality of life effects of once-daily cetirizine HCl syrup in children with seasonal allergic rhinitis.

Seasonal allergic rhinitis (SAR) can adversely impact children's physical, psychological, and social functioning and well-being, that is, their health-related quality of life (HRQL). This study assessed HRQL in children 6 to 11 years treated with cetirizine HCl syrup, while concurrently assessing symptomatic relief and safety. In an open-label, non-comparative study, 544 children from 124 centers in the United States were instructed to take cetirizine HCl syrup (10 cc of 1 mg/mL) each evening for 4 weeks.

One-year trial on safety and normal linear growth with flunisolide HFA in children with asthma.

Flunisolide hydrofluoroalkane (HFA) has efficacy equivalent to that of flunisolide chlorofluorocarbon (CFC) at one third the dose of the CFC formulation, a reduction from 250 microg/puff for flunisolide CFC to 85 microg/puff for flunisolide HFA. Flunisolide HFA delivers a smaller particle size (1.2 microm) in solution, resulting in improved lung deposition as compared with flunisolide CFC (3.
