Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics01:23

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

1.4K
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by...

Drugs Used in Upper Respiratory Disorders: Overview

825
Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...

Direct-Acting Cholinergic Agonists: Therapeutic Uses01:11

Direct-Acting Cholinergic Agonists: Therapeutic Uses

1.9K
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...

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...

Antiasthma Drugs: Muscarinic Receptor Antagonists

2.0K
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...

Area of Science:

  • Respiratory Cell Biology
  • Pharmacology
  • Biotechnology

Background:

  • Myrtol standardized (Gelomyrtol forte) aids rhinosinusitis symptom management by improving mucociliary clearance.
  • Investigating the in-vitro effects of myrtol on nasal ciliated and goblet cells is crucial for understanding its therapeutic mechanisms.

Purpose of the Study:

  • To assess the short- and long-term impacts of myrtol standardized on ciliated columnar and goblet cells in an in-vitro model.
  • To elucidate the cellular and molecular mechanisms underlying myrtol's effects on nasal epithelium.

Main Methods:

  • Human nasal epithelial stem/progenitor cells (hNESPCs) were cultured to form an air-liquid interface (ALI) model.
  • Myrtol 0.1% was applied to ALI cultures at different time points, followed by evaluation of ciliary beat frequency (CBF) and cell markers.

Main Results:

  • Long-term myrtol treatment increased cilia area and ciliogenesis markers (Foxj1, CP110) without altering CBF.
  • Short-term myrtol exposure significantly enhanced mucin secretion from goblet cells.

Conclusions:

  • Myrtol standardized stimulates goblet cell mucus production in the short term.
  • Myrtol standardized promotes ciliated cell differentiation over the long term.
  • These findings support myrtol's role in improving nasal symptom control through distinct cellular effects.
