Pharmacology of non sedating antihistamines

18 Apr

A tricyclic drug similar to Elavil with muscle relaxant qualities.May be taken along with Elavil to provide muscle relaxant relief.Antihistamines are used in the treatment of allergic reactions, colds, hay fever, hives, and insect bites and stings.Some antihistamines may also be helpful in reducing anxiety, inducing sleep, or at preventing or treating motion sickness.Some sedatives can cause psychological and physical dependence when taken regularly over a period of time, even at therapeutic doses.Dependent users may get withdrawal symptoms ranging from restlessness and insomnia to convulsions and death.

Advances in pharmacology have permitted more specific targeting of receptors, and greater selectivity of agents, which necessitates greater precision when describing these agents and their effects: Doctors often administer sedatives to patients in order to dull the patient's anxiety related to painful or anxiety-provoking procedures.Aspirin use is discouraged in children due to the risk of Reye’s syndrome.Although the risk is probably low, it is also discouraged in nursing mothers because of the potential risk of Reye’s syndrome and bleeding.Rupatadine fumarate has been approved for the treatment of allergic rhinitis and chronic urticaria in adults and children over 12 years.It is available as round, light salmon coloured tablets containing 10 mg of rupatadine (as fumarate) to be administered orally, once a day.The efficacy of rupatadine as treatment for allergic rhinitis (AR) and chronic idiopathic urticaria (CIU) has been investigated in adults and adolescents (aged over 12 years) in several controlled studies, showing a rapid onset of action and a good safety profile even in prolonged treatment periods of a year. However, as in other non sedating second-generation antihistamines, the most common side effects in controlled clinical studies were somnolence, headaches and fatigue.Rupatadine is a second generation, non-sedating, long-acting histamine antagonist with selective peripheral H Rupatadine possesses anti-allergic properties such as the inhibition of the degranulation of mast cells induced by immunological and non-immunological stimuli, and inhibition of the release of cytokines, particularly of the tumor necrosis factors (TNF) in human mast cells and monocytes.Although sedatives do not relieve pain in themselves, they can be a useful adjunct to analgesics in preparing patients for surgery, and are commonly given to patients before they are anaesthetized, or before other highly uncomfortable and invasive procedures like cardiac catheterization, colonoscopy or MRI.They increase tractability and compliance of children or troublesome or demanding patients.Analgesics generally recommended are: Tylenol, Tylenol with codeine, Vicodin, Darvon and Ultram.These medications, except Tylenol are prescribed for pain at the physician's discretion and are generally prescribed for those requiring a greater analgesic effect than acetaminophen alone can deliver, and/or those who are allergic to, or cannot take aspirin.: Drugs made from naturally occurring and synthetic substances that combat bacterial infection.
