European Review for Medical and Pharmacological Sciences
|December 16, 2022
Summary
Menthol may worsen allergic rhinitis (AR) symptoms by stimulating cold receptors and potentially histamine release. Individuals with allergies should avoid menthol-containing products to prevent adverse reactions.
Area of Science:
- Immunology
- Pharmacology
Background:
- Allergic rhinitis (AR) is a nasal inflammation causing symptoms like congestion and itching.
- Menthol, a cooling agent from peppermint, affects the respiratory system.
Approach:
- A literature survey was conducted using PubMed, Google, and Google Scholar.
- The review focused on the relationship between menthol and allergic rhinitis.
Key Points:
- Menthol can trigger allergic reactions, including asthma, AR, and urticaria.
- It stimulates the TRPM8 receptor and may cause dose-dependent histamine release.
- Menthol provides a sensation of freer airflow by stimulating cold receptors, but can provoke hypersensitivity.
Conclusions:
- Menthol-containing products may exacerbate allergic rhinitis and other allergic disorders.
- It is advisable to avoid menthol if diagnosed with an allergic condition.

01:16Drugs Used in Upper Respiratory Disorders: Overview
328
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...

01:23Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
381
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...

01:20Asthma: Pathogenesis and Management
511
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
395
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...

01:24Antiasthma Drugs: Methylxanthines
325
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,...

01:28Adrenergic Agonists: Mixed-Action Agents
810
Mixed-action adrenergic agonists, like ephedrine and pseudoephedrine, directly and indirectly affect adrenergic receptors. These agents stimulate adrenoceptors and indirectly release stored neurotransmitters, amplifying the adrenergic response.
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
