An anti-asthmatic agent, also known as an anti-asthma drug, refers to a drug 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 ...
Competitive inhibitors are commonly used to make pharmaceuticals. [3] For example, methotrexate is a chemotherapy drug that acts as a competitive inhibitor. It is structurally similar to the coenzyme, folate, which binds to the enzyme dihydrofolate reductase. [3]
The medical uses for Cysteinyl-leukotriene type 1 receptor antagonists are for chronic and prophylactic treatment of asthma. [3] [9] [10] Other indications have been approved by the FDA for montelukast and they are used for the prevention of exercise-induced bronchoconstriction (EIB), relief of symptoms of allergic rhinitis (AR) that is for relief of seasonal allergic rhinitis and perennial ...
Arachidonate 5-lipoxygenase inhibitors are compounds that slow or stop the action of the arachidonate 5-lipoxygenase (5-lipoxygenase or 5-LOX) enzyme, which is responsible for the production of inflammatory leukotrienes. The overproduction of leukotrienes is a major cause of inflammation in asthma, allergic rhinitis, and osteoarthritis. [1] [2]
For example, the clinical trial results of omalizumab on asthma have unambiguously settled the long debate on whether IgE plays a central role in the pathogenesis of asthma. [30] Numerous investigator-initiated case studies or small-scale pilot studies of omalizumab have been performed on various allergic diseases and several non-allergic ...
Ethyl alcohol or fomepizole used in methyl alcohol or ethylene glycol poisoning is a typical example of competitive enzyme inhibition. By posing competition for alcohol dehydrogenase (ADH) with methyl alcohol and ethylene glycol, these drugs reduce the production of harmful metabolites. [ 38 ]
NMDA receptor antagonists induce a state called dissociative anesthesia, marked by catalepsy, amnesia, and analgesia. [1] Ketamine is a favored anesthetic for emergency patients with unknown medical history and in the treatment of burn victims because it depresses breathing and circulation less than other anesthetics.
