In enzymology, a formaldehyde dehydrogenase (EC 1.2.1.46) is an enzyme that catalyzes the chemical reaction formaldehyde + NAD + + H 2 O ⇌ {\displaystyle \rightleftharpoons } formate + NADH + H + The 3 substrates of this enzyme are formaldehyde , NAD + , and H 2 O , whereas its 3 products are formate , NADH , and H + .
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.
Formaldehyde inhaled at this concentration may cause headaches, a burning sensation in the throat, and difficulty breathing, and can trigger or aggravate asthma symptoms.

[18] Salicylate sensitivity Salicylates can trigger asthma in sensitive individuals. Salicylates ...
Sensitizer-induced occupational asthma is an immunologic form of asthma which occurs due to inhalation of specific substances (i.e., high-molecular-weight proteins from plants and animal origins, or low-molecular-weight agents that include chemicals, metals and wood dusts) and occurs after a latency period of several weeks to years.
