[Post-irradiation morphea in brest cancer: a case report].

We report the case of a caucasian woman of 44 years old with no personal medical history. She was diagnosed breast carcinoma and underwent right partial mastectomy with adjuvant radiotherapy and chemotherapy. Four years after the intervention, presented a indurated plaque.

Aclidinium bromide, a novel long-acting muscarinic antagonist for COPD with improved preclinical renal and urinary safety profile.

Aims: Aclidinium bromide is a novel, long-acting, inhaled muscarinic antagonist currently in registration phase for the treatment of chronic obstructive pulmonary disease. Since urinary difficulty and retention have been reported for anticholinergic agents such as tiotropium and ipratropium, it is important to examine the preclinical urinary and renal safety profile of aclidinium.

Main Methods: The effect of aclidinium on urine and electrolyte excretion, renal function and voiding cystometry was analysed in conscious water-loaded Wistar rats (10-1000 μg/kg, s.

Characterization of aclidinium bromide, a novel inhaled muscarinic antagonist, with long duration of action and a favorable pharmacological profile.

Aclidinium bromide is a novel potent, long-acting inhaled muscarinic antagonist in development for the treatment of chronic obstructive pulmonary disease. Aclidinium showed subnanomolar affinity for the five human muscarinic receptors (M(1)-M(5)). [(3)H]Aclidinium dissociated slightly faster from M(2) and M(3) receptors than [(3)H]tiotropium but much more slowly than [(3)H]ipratropium.

Comparative antiallergic effects of second-generation H1-antihistamines ebastine, cetirizine and loratadine in preclinical models.

Ebastine (CAS 90729-43-4), cetirizine (CAS 83881-51-0) and loratadine (CAS 79794-75-5) are second generation H1-antihistamines of proven efficacy for treating allergy. Recent clinical studies have found ebastine to be more effective than cetirizine or loratadine in alleviating the symptoms of seasonal allergic rhinitis. The objective of this study was to compare the efficacy of these compounds in three guinea-pig modeles of bronchoconstriction, elicited either by histamine, allergen or leukotriene C4 in order to shed light onto the mechanisms that might explain differences found in clinical studies.
