Summary
Anticholinergics provide significant benefits for acute asthma attacks, unlike in chronic asthma. This suggests increased cholinergic bronchoconstriction in acute asthma may involve M2 muscarinic receptor changes.
Area of Science:
- Pharmacology
- Respiratory Medicine
- Clinical Therapeutics
Background:
- Anticholinergics are widely prescribed for various airway diseases.
- Their efficacy in chronic asthma is comparable to beta-agonists.
- Growing evidence supports their added benefit in acute asthma exacerbations.
Purpose of the Study:
- To investigate the enhanced response to anticholinergics during acute asthma attacks.
- To explore potential mechanisms, including M2 muscarinic receptor alterations.
- To review anticholinergic use in chronic obstructive pulmonary disease and rhinitis.
Main Methods:
- Literature review and synthesis of existing evidence.
- Analysis of mechanisms underlying cholinergic bronchoconstriction.
- Discussion of clinical applications in different airway conditions.
Main Results:
- Anticholinergics demonstrate substantial additional benefit in acute asthma attacks.
- Cholinergic bronchoconstriction appears heightened during acute asthma.
- Potential mechanisms involve altered M2 muscarinic receptor expression and function.
Conclusions:
- Anticholinergics are valuable adjuncts in managing acute asthma exacerbations.
- Understanding M2 receptor modulation may reveal new therapeutic targets.
- Anticholinergic utility extends to COPD and rhinitis management.

01:11Direct-Acting Cholinergic Agonists: Therapeutic Uses
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren syndrome.
01:30Indirect-Acting Cholinergic Agonists: Pharmacological Actions
Indirect-acting cholinergic agonists, also known as anticholinesterases, exert their pharmacological effects by enhancing cholinergic transmission in various body parts, including the neuromuscular junction, autonomic cholinergic synapses, and the brain.
At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...

01:24Cholinergic Antagonists: Pharmacokinetics
Cholinergic antagonists—such as antimuscarinics—are available in oral, topical, ocular, parenteral, and inhalational formulations. Most antimuscarinics are oral formulations, while scopolamine is available as a topical patch, and ipratropium and tiotropium are available as inhalation aerosols or powders. Atropine, tropicamide, and cyclopentolate are topically instilled in the eye. Most antimuscarinics are lipid-soluble and readily absorbed from the gastrointestinal tract and the conjunctiva.
01:28Cholinergic Antagonists: Pharmacological Actions
Antimuscarinic drugs block muscarinic receptors in multiple systems, including the gut, eye, smooth muscles, respiratory tract, cardiovascular, and central nervous systems. They produce similar effects with varying selectivity depending on the specific agent and tissue. Here are the key pharmacological actions of antimuscarinics:
Gastrointestinal Effects: Antimuscarinics reduce gut contractions, increase gastric emptying, and slow intestinal transit. They partly inhibit gastric acid secretion...

01:26Cholinergic Antagonists: Therapeutic Uses
Antimuscarinic drugs have various therapeutic applications by inhibiting parasympathetic stimulation in different systems. Here are the key therapeutic uses of antimuscarinics:
Respiratory Tract: Ipratropium, aclidinium, and tiotropium treat asthma, chronic bronchitis, and chronic obstructive pulmonary disease (COPD). They protect against bronchoconstriction caused by irritants like cigarette smoke, sulfur dioxide, and ozone. They also help reduce nasopharyngeal secretions in common...

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...
