Asthma allergic rhinitis and

Atopy A genetic predisposition to develop type I hypersensitivity reactions against common environmental antigens commonly seen in patients with allergic rhinitis, asthma, and atopic dermatitis. 

Flunisolide is a fast-acting corticoid designed for the treatment of allergic rhinitis, asthma, and other allied respiratory disorders in humans. As the quantum of drug delivered by inhalation (/. e., the usual route of administration of the drug), is invariably small, the plasma-levels attained can also be fairly small. Hence, there is a dire need for a sensitive method of plasma concentration evaluation which is satisfied by radioimmunoassay. 

There is steady growing evidence that environmental exposure to insects at home and in the workplace are the frequent causes of allergic sensitization (Arlian 2002). Subsequently clinical symptoms are mainly of respiratory nature, manifested in allergic rhinitis, asthma, and urticaria (Steen et al. 2004), and in some documented cases also via ingestion, causing systemic anaphylaxis. 

Allergic rhinitis, asthma and/or atopic dermatitis were seen in 58 of 234 bakery employees (25%) 14 had atopic dermatitis. Of these 14, 3 had positive intracu-taneous tests to one or more of the flours they used. One of those who had a positive skin test experienced aggravation of hand eczema upon contact with flour, and another experienced aggravation of atopic dermatitis of the neck (Jarvinen et al. 1979). 

Mechanism of Action An antiasthmatic and antiallergic agent that prevents mast cell release of histamine, leukotrienes, and slow-reacting substances of anaphylaxis by inhibiting degranulation after contact with antigens. Therapeutic Effect Helps prevent symptoms of asthma, allergic rhinitis, mastocytosis, and exercise-induced bron-chospasm.

Corticosteroids—a group of anti-inflammatory drugs similar to the natural corticosteroid hormones produced by the cortex of the adrenal glands. The disorders that often improve upon corticosteroid treatment include asthma, allergic rhinitis, eczema, and rheumatoid arthritis. 

Second-generation antihistamines have proved to be important therapeutic tools in the treatment of atopic disease, including both seasonal and perennial allergic rhinitis, urticaria, and atopic dermatitis (20). Several studies have shown that the use of second-generation antihistamines as adjunctive therapy can benefit patients whose allergic asthma co-exists with allergic rhinitis (21). 

Although predictive factors for allergic rhinitis, conjunctivitis and the IgE-associated subgroup of eczema, i.e. atopic eczema, are presented, the primary focus of this chapter is on asthma in at least 80% of children and 50% of adults, asthma is associated with an IgE sensitisation.

Castor oil contains a triglyceride of ricinoleic acid which is hydrolyzed by intestinal lipases to glycerol and ricinoleic acid, which has cathartic effects. Allergic reactions such as angioedema, rhinitis, asthma, and scarlatiniform rashes have been described but seem to be rare reactions to this common laxative (Bennett and Schwartz 1934 Blank 1945). 

As in other types of drug hypersensitivity, skin testing often yields variable results. Farah and Shbaklu (1971) reported positive skin tests on intradermal injections of progesterone and confirmed the sensitivity of both their patients by passive cutaneous transfer tests. Falliers (1974) noted that 10 out of 11 women with either allergic rhinitis/asthma or urticaria had strong positive wheal and erythema reactions. In contrast, the patients treated by Pelikan (1978) did not show a good correlation between the results of nasal provocation and either scratch or patch tests.
