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]
When used as drugs, the International Nonproprietary Names (INNs) end in -mab. The remaining syllables of the INNs, as well as the column Source, are explained in Nomenclature of monoclonal antibodies. Types of monoclonal antibodies with other structures than naturally occurring antibodies.
Drugs with muscarinic antagonist activity are widely used in medicine, in the treatment of low heart rate, overactive bladder, respiratory problems such as asthma and chronic obstructive pulmonary disease (COPD), and neurological problems such as Parkinson's disease and Alzheimer's disease.
Tezepelumab, sold under the brand name Tezspire, is a human monoclonal antibody used for the treatment of asthma. [5] [7] [8] [9] Tezepelumab blocks thymic stromal lymphopoietin (TSLP), [5] an epithelial cytokine that has been suggested to be critical in the initiation and persistence of airway inflammation.
LABAs are designed to reduce the need for shorter-acting β 2 agonists such as salbutamol (albuterol), as they have an approximately twelve-hour duration of action, compared to about five hours for salbutamol, making them candidates for sparing high doses of corticosteroids [citation needed] or treating nocturnal asthma and providing ...
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]
If the non-competitive antagonist binds to the allosteric site and an agonist binds to the ligand site, the receptor will remain unactivated. [9] [10] An example of an adrenergic non competitive antagonists is phenoxybenzamine. This drug is a non-selective α-adrenergic antagonist, which means it binds to both alpha receptors. [11]
