Drugs Used in Lower Respiratory Disorders: Overview01:17

Drugs Used in Lower Respiratory Disorders: Overview

969
Lower respiratory tract disorders present challenges that often require skilled and nuanced approaches for effective management. Common ailments, such as asthma and chronic obstructive pulmonary disease (COPD), have prompted the development of intricate treatment strategies involving bronchodilators and anti-inflammatory drugs, each tailored to ease breathing and revitalize the lungs.
Bronchodilators, the first step of respiration enhancement, come in various forms, each with its own mechanism...

Drugs Used in Upper Respiratory Disorders: Overview01:16

Drugs Used in Upper Respiratory Disorders: Overview

579
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...

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...

Summary

Allergic rhinitis patients often show subclinical lung function changes, indicating a potential for latent asthma. Pulmonary function tests are crucial for early detection in these individuals.

Area of Science:

  • Pulmonology
  • Allergology
  • Clinical Medicine

Background:

  • Established link between allergic rhinitis and bronchial asthma.
  • Bronchial hyper-responsiveness can lead to abnormal pulmonary function tests.
  • Investigating subclinical pulmonary derangements in allergic rhinitis patients.

Purpose of the Study:

  • To identify pulmonary function derangements in allergic rhinitis patients without overt asthma symptoms.
  • To assess the prevalence of subclinical lung disease in this population.
  • To compare findings with previous international studies.

Main Methods:

  • Studied 74 patients diagnosed with allergic rhinitis.
  • Conducted clinical evaluation, blood tests (hemogram, eosinophil count, total IgE).
  • Performed pulmonary function tests (PFTs) to assess lung function.

Main Results:

  • 60% had intermittent allergic rhinitis, 19% persistent.
  • 24.3% showed reversible obstruction (asthma-like response on PFTs).
  • 14 patients had mild obstruction, 4 had moderate obstruction.

Conclusions:

  • Highlights the significance of pulmonary symptoms in allergic rhinitis.
  • Recommends pulmonary function tests for allergic rhinitis patients.
  • Emphasizes ruling out latent asthma in individuals with allergic rhinitis.
