Asthma & COPD Treatments

Asthma and chronic obstructive pulmonary disease (COPD) are two of the most prevalent respiratory conditions worldwide. While they share some symptoms, including breathlessness, wheezing, and coughing, they differ in their underlying mechanisms and typical age of onset. Asthma usually begins in childhood and is characterised by reversible airway narrowing, whereas COPD is most commonly seen in adults over 40 with a history of smoking and involves progressive, largely irreversible airflow limitation.

Both conditions involve chronic inflammation of the airways, which makes them hypersensitive to triggers such as allergens, cold air, exercise, and air pollution. During a flare-up or exacerbation, the airway muscles tighten, the lining swells, and excess mucus is produced, all of which restrict airflow and make breathing difficult.

With appropriate treatment and self-management, most people with asthma achieve excellent symptom control, and those with COPD can slow disease progression and maintain a good quality of life. The cornerstone of management for both conditions is inhaled therapy, supported by an individualised action plan.

Inhalers fall into two broad categories: relievers and preventers. Reliever inhalers, typically containing short-acting beta-agonists such as salbutamol (Ventolin), relax the muscles around the airways within minutes and are used to treat acute symptoms. They should be carried at all times but ideally needed infrequently, as regular reliance on a reliever suggests that the underlying condition is not well controlled.

Preventer inhalers contain inhaled corticosteroids (ICS) such as beclometasone, budesonide, or fluticasone. These reduce inflammation in the airways over time and must be used daily to be effective, even when symptoms are absent. It can take several weeks of consistent use before the full protective benefit is felt.

Combination inhalers, such as Symbicort (budesonide/formoterol) and Seretide (fluticasone/salmeterol), deliver both a corticosteroid and a long-acting bronchodilator in a single device. They are commonly prescribed for patients whose asthma or COPD is not adequately controlled by a preventer alone. Choosing the right inhaler device, whether a metered-dose inhaler, dry-powder inhaler, or soft-mist inhaler, is just as important as choosing the right medication, since correct technique determines how much drug actually reaches the lungs.

Identifying and avoiding personal triggers is a vital part of respiratory disease management. Common asthma triggers include house dust mites, pet dander, pollen, mould, tobacco smoke, and strong fragrances. For COPD patients, respiratory infections and air pollution are particularly dangerous, often precipitating exacerbations that require hospital admission.

An asthma or COPD action plan, agreed with your healthcare team, provides clear instructions on what to do when symptoms worsen. This typically involves increasing your preventer medication, using your reliever more frequently, and knowing when to seek emergency help. Having a written plan has been shown to reduce hospital admissions and improve outcomes.

Annual influenza vaccination and pneumococcal vaccination are strongly recommended for anyone with a chronic respiratory condition, as infections can trigger severe flare-ups. Staying physically active, maintaining a healthy weight, and practising breathing exercises also contribute to better lung function and overall wellbeing.

Regular monitoring helps detect changes in lung function before symptoms become severe. Peak flow meters are inexpensive, portable devices that measure how fast air can be expelled from the lungs. Daily peak flow readings at home allow patients and clinicians to spot trends, adjust treatment, and intervene early during a deterioration.

Spirometry, a more detailed lung function test performed in a clinic, is used to diagnose asthma and COPD and to assess severity over time. For asthma, the key finding is a reversible obstruction that improves after using a bronchodilator. For COPD, the hallmark is a fixed obstruction that does not fully reverse.

Keeping a symptom diary, noting night-time waking, exercise tolerance, and reliever use, gives your prescriber valuable information at review appointments. Many smartphone apps now offer digital tracking alongside medication reminders, making it easier to stay on top of your condition between consultations.

Repeat prescriptions for well-established asthma and COPD medications can be conveniently ordered through regulated online pharmacies. This is particularly helpful for patients who have a stable diagnosis, a clear treatment plan, and simply need to replenish their supply of inhalers or other maintenance therapy.

The process involves confirming your current medication, dosage, and recent review status through an online consultation. A prescriber checks that the request is appropriate and that your condition remains under adequate control. Medications are then dispatched from a licensed pharmacy, usually with next-day delivery available.

Online ordering does not replace the need for periodic face-to-face or telephone reviews with your GP or respiratory nurse. An annual review is recommended for asthma, and more frequent assessments may be needed for COPD. If you are experiencing worsening symptoms, increased reliever use, or a new exacerbation, seek a full medical review rather than simply reordering medication.
