[Pulmonary volume and flows in asthmatic children in therapy with prompt and delayed-action theophylline: preliminary

Insights

Plain theophylline showed better results than sustained-release (SR) theophylline in improving lung function in asthmatic children. Further studies are needed to confirm SR theophylline

Area of Science:

  • Pediatric Pulmonology
  • Pharmacology
  • Respiratory Medicine

Context:

  • Asthma management in children requires effective long-term therapies.
  • Theophylline is a bronchodilator used for asthma prophylaxis.
  • Sustained-release (SR) theophylline formulations aim for improved compliance and efficacy.

Purpose:

  • To compare the efficacy of plain theophylline versus SR theophylline in pediatric asthma.
  • To evaluate the impact of these theophylline formulations on pulmonary function tests.
  • To assess bronchodilator response after Albuterol inhalation.

Summary:

  • A study involving 12 asthmatic children compared plain theophylline, SR theophylline, and no therapy.
  • Pulmonary function (statics, dynamics, and flow-volume curves) was assessed using body plethysmography before and after Albuterol inhalation.
  • Plain theophylline demonstrated superior effects on static lung volumes (TV, RV, FRC) and dynamic parameters (MMEF, V 0.50 TV) compared to SR theophylline.

Impact:

  • Findings suggest plain theophylline may be more effective than current SR formulations for children's asthma.
  • Highlights the need for further pharmacokinetic, clinical, and spirometric research.
  • Informs potential therapeutic strategies for long-term asthma control in pediatric populations.

Drugs Used in Lower Respiratory Disorders: Overview

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...

Antiasthma 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,...

Inhaled Medications

Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Asthma 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,...
