Anti-asthmatic agents, also known as anti-asthma drugs, refer to drugs that can aid in airway smooth muscle dilation to allow normal breathing during an asthma attack or reduce inflammation on the airway to decrease airway resistance for asthmatic patients, or both. The goal of asthmatic agents is to reduce asthma exacerbation frequencies and ...
In 1968 Andor Szentivanyi first described The Beta Adrenergic Theory of Asthma; in which blockage of the Beta-2 receptors of pulmonary smooth muscle cells causes asthma. [27] Szentivanyi's Beta Adrenergic Theory is a citation classic [ 28 ] using the Science Citation Index and has been cited more times than any other article in the history of ...
Formaldehyde inhaled at this concentration may cause headaches, a burning sensation in the throat, and difficulty breathing, and can trigger or aggravate asthma symptoms. [70] [71] The CDC considers formaldehyde as a systemic poison. Formaldehyde poisoning can cause permanent changes in the nervous system's functions. [72]
Furthermore, patients with asthma are found to have an increased release of type II cytokines, especially IL4 and IL5, but a normal or low level of type I cytokine production. Similarly, M. pneumoniae infection promotes a T helper type 2 response, which is why M. pneumoniae -positive patients with asthma have increased airways expression of ...
They are spiral-shaped mucus plugs from subepithelial mucous gland ducts of bronchi. They may occur in several different lung diseases [1] and may refer to parts of the desquamated epithelium seen in lavages from asthmatic patients. [2] These microscopic casts are named after German physician Heinrich Curschmann (1846-1910).
Occupational asthma is new onset asthma or the recurrence of previously quiescent asthma directly caused by exposure to an agent at workplace. It is an occupational lung disease and a type of work-related asthma. Agents that can induce occupational asthma can be grouped into sensitizers and irritants. [1]
Other causes can include acid reflux, asthma, allergies, or other chronic medical conditions, adds Richard Watkins, M.D., an infectious disease physician and professor of medicine at the Northeast ...
Image of aspirin which can be a trigger for asthma in some patients. Aspirin induced asthma, or aspirin-exacerbated respiratory disease, refers to situations where the use of aspirin worsen the asthma conditions. [34] Other non-steroidal anti-inflammatory drugs (NSAIDs) that inhibits the enzyme, cyclooxygenase-1, may also lead to an asthma attack.
