Journal of the European Academy of Dermatology and Venereology : JEADV, 19(3), 319-322 (2005-04-29)
As the current antipsoriatic medications are commonly associated with deleterious side-effects, a determined search for safer agents, which could be used alone or in combination with current antipsoriatic drugs, would be very imperative. Psoriasis is believed to be characterized by
I J Roman et al.
Clinical reviews in allergy, 11(1), 89-110 (1993-01-01)
Antihistamines are considered first-line therapy for the relief of symptoms from allergic rhinitis and chronic urticaria. The newer, second-generation, nonsedating antihistamines reduce the central nervous system and anticholinergic side effects commonly found with previous drugs. The availability of H1-receptor antagonists
M Haria et al.
Drugs, 48(4), 617-637 (1994-10-01)
Loratadine is a long-acting antihistamine agent, exhibiting partial selectivity for peripheral histamine H1-receptors. To date, loratadine has been evaluated in allergic rhinitis, urticaria and, to a limited extent, in asthma. In several large controlled comparative clinical studies, loratadine was superior

Clinical and experimental allergy : journal of the British Society for Allergy and Clinical Immunology, 29 Suppl 3, 197-199 (1999-08-12)
The extremely low reporting rate of cardiovascular adverse events for loratadine, the possible preferential use of loratadine in patients with pre-existing cardiovascular disorders, and the impressive lack of cardiovascular effects at extremely high concentrations in clinical and preclinical studies demonstrate
