Document Summary

Allergy is immune system response when body mistakes certain food as a harmful substance (affects 4% of adults) Hygiene hypothesis: suggests that the immune system needs to come into contact with a variety of microorganisms and bacteria while it"s developing at the infant stage. People are exposed to less natural things, society is too clean . Mast cells release histamine (inflammatory) to trigger allergic reactions. First gen can enter the brain e. g. diphenhydramine (benadryl), histamine antagonists. Second gen does not enter the brain e. g. loratadine (claritin), doesn"t cause drowsiness. Body responds to desired effect in an unintended way. Active component of chili peppers that binds to heat sensing neurons, acts as agonist. Capsaicin dissolves in fat so it unbinds from your taste receptors. Excipients: inert substances used to bind contents of a pill. Fillers: inactive substance used to make active component of drug easier to measure. Stabilizers: protect drugs from reacting with oxygen. Preservatives: protect drugs from degradation by microbes.
