Loratadine

Description

desloratadine is available off the shelf in Canada); Loratadine is a tricyclic antihistamine, which has a selective and peripheral H1-antagonist action. It has a long-lasting effect and does not normally cause drowsiness because it does not readily enter the central nervous system; An antiviral that is used in the prophylactic or symptomatic treatment of influenza A. It is also used as an antiparkinsonian agent, to treat extrapyramidal reactions, and for postherpetic neuralgia. The mechanisms of its effects in movement disorders are not well understood but probably reflect an increase in synthesis and release of dopamine, with perhaps some inhibition of dopamine uptake; Loratadine is a drug used to treat allergies. It is marketed by Schering-Plough under several trade names such as Claritin, Clarityn or Claratyne depending on the market, by Lek as Lomilan and by Wyeth as Alavert. It is also available as a generic; Loratadine is a drug used to treat allergies. It is marketed by Schering-Plough under several trade names such as Claritin, Clarityn or Claratyne depending on the market, by Lek as Lomilan and by Wyeth as Alavert. It is also available as a generic. Its active metabolite, desloratadine, is also on the market, though loratadine itself is the only drug of its class available over the counter (at least in the U.S. as of 2005. Loratadine is available off the shelf in the UK [HMDB]
