This particular illness is a type of asthmatic condition where the bronchi and the lower airway of the respiratory system is inflamed by irritants and allergens. In allergic bronchitis, asthma and respiratory allergies are present. This can cause a condition called hay fever or allergic rhinitis. Allergic bronchitis is also commonly called as allergic asthma. This particular condition is triggered by an overly active immune system that attacks harmless foreign substances that enters the body. The immune system identifies the foreign substance as dangerous and releases antibodies to fight the substance.
BRAND NAME: None available. DRUG CLASS AND MECHANISM: Propylthiouracil (PTU) is an oral medication that is used to manage hyperthyroidism which is due to an overactive thyroid gland. It is an anti-thyroid drug that has a mechanism of action that is similar to methimazole (Tapazole). Graves' disease is the most common cause of hyperthyroidism.
Propylthiouracil inhibits the synthesis of thyroid hormones and thus is effective in the treatment of hyperthyroidism. The drug does not inactivate existing thyroxine and triiodothyronine that are stored in the thyroid or circulating in the blood, nor does it interfere with the effectiveness of thyroid hormones given by mouth or by injection.
