Allergy

Allergy is an alternative reaction to an ingredient unknown to the organism which is quick, acquired and predictable. In its close meaning it's the first class of five known types of hypersensitivity, listed in Coombs and Gell classification produced in 1963. In fact, the definition "allergy" is commonly applied to other alternative reactions to ingredients. The definition was produced by Clemens von Pirquet in 1906 after several of patients appeared to be strangely sensitive to such common things as pollen, dust or particular meals. To be aware of all the allergies a patient may possess is necessary in medicinal treatment. Patient's allergy history is always considered if obtaining his medical history. This can protect the patients from being prescribed some medicines harmful to his health. Some antagonistic medicines are applied to neutralize the activity of allergy mediators, or to escape the process of cells activation and degranulation. They are: Atarax, Allegra, Clarinex, Claritin, Zyrtec. Other components (some of them can lessen eosinophil chemotaxis) are as well usually applied.
