Asthma & COPD Care Guide
Asthma and chronic obstructive pulmonary disease (COPD) share a common therapeutic goal: maintaining airway patency, reducing inflammation, and preventing acute exacerbations that can jeopardize quality of life. In Singapore, clinicians prescribe a combination of controller medications-such as inhaled corticosteroids, long-acting beta-agonists, and leukotriene modifiers-to achieve long-term stability, while rescue inhalers containing short-acting bronchodilators provide rapid relief during symptom flare-ups. Treatment is indicated when patients experience recurrent wheeze, dyspnoea, cough, or reduced exercise tolerance despite environmental control measures. Controllers are typically initiated after a confirmed diagnosis by spirometry, whereas rescue agents are kept on hand for immediate symptom relief. The category encompasses prescription inhalers, some over-the-counter (OTC) bronchodilators, and oral agents, all of which are regulated by Singapore’s Health Sciences Authority to ensure safety and efficacy. Understanding the distinct roles of each medication class helps patients and providers tailor regimens that balance symptom control with minimal side-effects, ultimately aiming for a life with fewer interruptions from breathlessness.
Understanding Asthma & COPD Care
In medical practice, “Asthma & COPD Care” refers to the full spectrum of pharmacologic options used to manage obstructive airway diseases. The primary symptoms addressed include wheezing, chest tightness, cough, and shortness of breath, all of which arise from reversible (asthma) or partially reversible (COPD) airway narrowing. Controllers act on the underlying inflammation or bronchial tone, while rescue agents counteract acute bronchospasm. In Singapore, inhaled medicines are classified as prescription-only, whereas oral leukotriene modifiers can be obtained OTC after pharmacist consultation. The category divides into several sub-domains: inhaled corticosteroids (ICS), long-acting β₂-agonists (LABA), combination inhalers (ICS/LABA), short-acting β₂-agonists (SABA), long-acting muscarinic antagonists (LAMA), and leukotriene receptor antagonists (LTRA). Treatment philosophy prioritises stepwise escalation-starting with low-dose controllers and adding rescue inhalers as needed-to achieve symptom-free days and reduce exacerbation frequency. Therapeutic goals include improved lung function, fewer hospital admissions, and enhanced activity tolerance.
Common Medications in This Category
Major Therapeutic Subcategories
- Inhaled Corticosteroids (ICS): Reduce airway inflammation by inhibiting cytokine production, forming the cornerstone of long-term asthma control and moderate COPD management.
- Long-Acting β₂-Agonists (LABA): Promote bronchodilation for up to 12-hour periods, often paired with an ICS to enhance symptom control while minimizing steroid exposure.
- Short-Acting β₂-Agonists (SABA): Provide rapid relief within minutes; albuterol and levalbuterol are typical agents used as rescue inhalers during sudden breathlessness.
- Long-Acting Muscarinic Antagonists (LAMA): Block acetylcholine-mediated bronchoconstriction, proving especially effective in COPD patients with persistent airflow limitation.
- Leukotriene Receptor Antagonists (LTRA): Oral tablets that blunt leukotriene-driven inflammation, useful as adjunct therapy for asthma or when inhaler technique is problematic.
These classes together form the therapeutic backbone for Asthma & COPD Care, allowing clinicians to customize regimens based on disease severity, patient preference, and comorbid conditions.

Treatment Considerations & Safety
All Asthma & COPD Care medications require medical supervision because dosing, device technique, and monitoring differ across agents. Controllers often demand a titration period of several weeks, during which lung function tests (spirometry) and symptom diaries guide dose adjustments. Rescue inhalers should be limited to short-term use; frequent reliance signals inadequate baseline control and warrants regimen review. Common drug interactions include β-blockers, which may blunt bronchodilator response, and high-dose systemic steroids, which increase infection risk. Contraindications arise with certain LAMA agents in patients with narrow-angle glaucoma or urinary retention. Regular follow-up-typically every 3-6 months-allows clinicians to assess inhaler technique, adherence, and adverse effects such as oral thrush from ICS or tachycardia from β₂-agonists. Patients should store inhalers at room temperature, keep spacers clean, and replace devices according to manufacturer timelines to maintain therapeutic efficacy.
Frequently Asked Questions
-
What determines whether I need a controller inhaler or a rescue inhaler? Controllers are prescribed for daily use to suppress underlying inflammation and prevent symptoms, while rescue inhalers are reserved for immediate relief of acute bronchospasm.
-
How do I know which type of inhaler device is right for me? Pressurized metered-dose inhalers, dry-powder inhalers, and soft mist inhalers each require specific inhalation techniques; your clinician will select a device that matches your breath strength and ability to coordinate actuation.
-
Can inhaled corticosteroids cause systemic side effects? At standard low to medium doses, systemic absorption is minimal, but high-dose or prolonged use can affect bone density and glucose control, prompting periodic monitoring.
-
Why are long-acting muscarinic antagonists preferred for COPD over asthma? LAMA agents target cholinergic pathways that dominate COPD-related airway constriction, delivering sustained bronchodilation without the inflammation-focused action of corticosteroids.
-
Are leukocyte-modifying tablets effective for severe asthma? Leukotriene receptor antagonists modestly reduce inflammation and can supplement inhaled therapy, yet they are generally less potent than high-dose ICS or biologics for severe disease.
-
What common supplements might interact with my bronchodilators? High doses of magnesium or caffeine can enhance β₂-agonist effects, potentially causing tremor or palpitations; discuss any supplement regimen with your healthcare provider.
-
Do I need to use a spacer with my rescue inhaler? A spacer reduces oropharyngeal deposition, improving drug delivery to the lungs and lowering the risk of thrush, especially when using corticosteroid-containing rescue blends.
-
How often should I replace my inhaler device? Most devices have a built-in dose counter; replace the inhaler when the counter reaches zero or if the mouthpiece becomes damaged, typically every 6-12 months.
-
Is it safe to travel with my inhalers on an international flight? Yes, but keep them in original packaging, carry a copy of the prescription, and inform security officials that they are essential medical devices.
-
Can pregnancy affect my asthma medication plan? Pregnancy may alter hormone levels and airway reactivity, so clinicians often adjust doses while prioritising medications with established safety records, such as low-dose inhaled corticosteroids.
