|January 1, 1979
Summary
A novel compound, RU 20201, demonstrates potent antitussive effects comparable to codeine in animal studies. Its local activity in the lungs suggests a direct mechanism on respiratory tract receptors.
Area of Science:
- Pharmacology
- Respiratory Medicine
- Drug Discovery
Background:
- Codeine is a widely used antitussive agent.
- Novel compounds are sought to improve cough suppression with potentially fewer side effects.
- Understanding the mechanism of action of new antitussive agents is crucial.
Purpose of the Study:
- To evaluate the antitussive activity of a novel compound, 1,2,3,4,4a,9b-hexahydro-8,9b-dimethyl-4-[3-(4-methylpiperazin-1-yl)propionamido]dibenzofuran-3-one dihydrochloride (RU 20201).
- To compare its efficacy with codeine phosphate.
- To investigate the potential mechanism of action and delivery routes.
Main Methods:
- Oral administration of RU 20201 and codeine phosphate in animal models.
- Aerosol administration of RU 20201 to assess local antitussive activity.
- Observation of immediate effects post-administration.
Main Results:
- RU 20201 exhibited comparable antitussive activity to codeine phosphate after oral administration.
- Aerosolized RU 20201 demonstrated immediate local antitussive effects.
- The compound appears to act directly on superficial receptors in the respiratory tract.
Conclusions:
- RU 20201 is a promising antitussive compound with efficacy similar to codeine.
- Its ability to act locally via aerosol suggests a targeted approach for cough suppression.
- Further research into the direct inhibition of respiratory tract receptors is warranted.

01:16Drugs Used in Upper Respiratory Disorders: Overview
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...

01:27Upper Respiratory Drugs: Decongestants
Decongestants are a class of medications used primarily to alleviate nasal congestion, a common symptom resulting from allergies, colds, sinusitis, and other upper respiratory tract infections. These drugs work by activating α-adrenergic receptors, constricting small blood vessels in the nasal membranes. This action results in the opening of clogged nasal passages, thereby facilitating sinus drainage and relieving congestion.

01:15Upper Respiratory Drugs: First and Second-Generation Antihistamines
Antihistamines are a class of drugs widely used to alleviate the symptoms of allergies, such as sneezing, itching, and nasal congestion. They work by inhibiting the actions of histamine, which is released by immune cells in response to allergenic substances or tissue injuries.
Histamine binds to specific receptor sites, known as H1 receptors, on tissue cells, triggering inflammation and swelling. Antihistamines combat these effects by competing with histamine for these receptor sites. By...

01:23Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
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 anesthetizing...

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,...

01:20Antiasthma 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...
