Leukotriene modifiers as novel therapeutics in asthma
1Merck and Co., Inc., Whitehouse Station, New Jersey 08889-0100, USA.
Summary
Cysteinyl leukotrienes are key players in chronic asthma, causing symptoms like bronchoconstriction. New leukotriene antagonists and inhibitors effectively treat asthma by blocking these inflammatory mediators.
Area of Science:
- Pharmacology
- Immunology
- Respiratory Medicine
Background:
- Slow-reacting substance of anaphylaxis components identified as cysteinyl leukotrienes (C4, D4, E4).
- Leukotrienes are recognized as critical mediators in chronic asthma pathogenesis.
Purpose of the Study:
- To investigate the role of leukotrienes in asthma.
- To evaluate the efficacy of leukotriene pathway inhibitors in asthma management.
Main Methods:
- Identification of cysteinyl leukotrienes as mediators.
- Administration of leukotriene receptor antagonists and biosynthesis inhibitors.
- Testing agents against laboratory challenges simulating asthma (exercise, allergen, aspirin).
Main Results:
- Leukotrienes induce bronchoconstriction, edema, and mucus secretion in asthma models.
- Asthmatic patients exhibit excessive leukotriene production.
- Leukotriene antagonists and inhibitors effectively mitigate asthma symptoms in diverse patient groups.
Conclusions:
- Leukotrienes are confirmed as significant mediators of chronic asthma.
- Leukotriene pathway inhibitors demonstrate therapeutic potential for asthma.
- Further research will define the precise role of these agents in asthma treatment.

01:17Drugs Used in Lower Respiratory Disorders: Overview
Lower respiratory tract disorders present challenges that often require skilled and nuanced approaches for effective management. Common ailments, such as asthma and chronic obstructive pulmonary disease (COPD), have prompted the development of intricate treatment strategies involving bronchodilators and anti-inflammatory drugs, each tailored to ease breathing and revitalize the lungs.

01:25Antiasthma Drugs: β2-Adrenoceptor Agonists
Bronchodilators are critical in managing asthma, a chronic respiratory condition characterized by airway constriction due to inflammation and hyper-reactivity. Specifically, bronchodilators ease this constriction by relaxing the bronchial muscles, facilitating easier breathing.
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce relaxation in these...

01:24Antiasthma Drugs: Methylxanthines
Theophylline, a member of the methylxanthine class of bronchodilators, has long been used in asthma management. While its exact mechanism of action is not fully understood, it is believed to have multiple effects on various cellular processes.
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...

01:19Antiasthma Drugs: Leukotriene Modifiers
Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.
Leukotriene modifiers work through two distinct mechanisms:

01:20Antiasthma Drugs: Muscarinic Receptor Antagonists
Muscarinic receptor antagonists, also known as antimuscarinic agents, are a class of bronchodilators used to treat asthma, although they are more commonly used to treat COPD. They work by inhibiting the action of acetylcholine (ACh), a neurotransmitter, on muscarinic receptors found in the airways.
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
