Summary
Continuous levocetirizine 5 mg daily offers better symptom control for persistent allergic rhinitis than on-demand use. This regimen also shows a trend towards improved quality of life and reduced nasal inflammation over six months.
Area of Science:
- Allergology and Immunology
- Pharmacology
- Clinical Medicine
Background:
- Allergic rhinitis significantly impacts patient quality of life (QOL), sleep, and productivity.
- Persistent allergic rhinitis is particularly troublesome and requires effective management strategies.
Purpose of the Study:
- To compare the efficacy of continuous daily levocetirizine 5 mg versus on-demand levocetirizine 5 mg in adults with persistent allergic rhinitis.
- To assess the impact of both treatment regimens on symptom scores, QOL, sleep quality, and nasal inflammation.
Main Methods:
- A 6-month, randomized, open-label pilot study involving symptomatic patients with persistent allergic rhinitis.
- Patients received either continuous daily levocetirizine 5 mg or on-demand levocetirizine 5 mg.
- Symptom scores, QOL, sleep quality, nasal cytology, drug intake, and safety were monitored.
Main Results:
- Both continuous and on-demand levocetirizine improved symptoms and QOL.
- Continuous therapy demonstrated superior symptom control from week 15 onwards, with statistical significance noted later in the study.
- Both treatments were well-tolerated, though the on-demand group reported more adverse events.
Conclusions:
- Levocetirizine 5 mg effectively manages persistent allergic rhinitis over six months.
- Continuous daily administration shows a trend towards greater efficacy in symptom control, QOL improvement, and reduced nasal inflammation compared to on-demand use.

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:

01:25Antiasthma 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...

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...

01:25Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

01:13Asthma III: Clinical Manifestations
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
