Novolizer Salbutamol (Salbutamol Sulfate)

Novolizer Salbutamol is a bronchodilator that acts on the β2‑adrenergic pathway to relax airway smooth muscle.

• Asthma: provides rapid relief of acute bronchospasm and improves airflow.
• Chronic obstructive pulmonary disease (COPD): alleviates episodic breathlessness and wheeze.
• Exercise‑induced bronchoconstriction: prevents airway narrowing during physical activity.

• Salbutamol binds selectively to β2‑adrenergic receptors on bronchial smooth‑muscle cells, activating adenylate cyclase and increasing intracellular cyclic AMP. The rise in cAMP leads to phosphorylation of myosin‑light‑chain kinase, resulting in smooth‑muscle relaxation and bronchodilation, which eases airflow obstruction.

Adverse reactions to inhaled salbutamol are generally dose‑related and may vary in frequency.

Common Side Effects

• Tremor: mild shaking of the hands or limbs.
• Headache: transient headache without focal neurological signs.
• Palpitations: sensation of rapid or irregular heartbeat.
• Throat irritation: mild soreness or dryness in the throat.
• Cough: brief cough following inhalation.
• Nausea: mild stomach upset.

Serious or Rare Side Effects

• Paradoxical bronchospasm: worsening of airway narrowing after inhalation.
• Cardiac arrhythmia: irregular heart rhythm, especially in patients with pre‑existing heart disease.
• Hypokalemia: low blood potassium levels that may cause muscle weakness.
• Severe allergic reaction: rash, itching, swelling, or difficulty breathing.
• Hyperglycaemia: elevated blood glucose, particularly in diabetic patients.
• Pulmonary oedema: fluid accumulation in the lungs, a rare but serious condition.

When using Novolizer Salbutamol, consider the following safety measures:

• Assess patient history: identify asthma severity, COPD stage, and cardiac comorbidities.
• Monitor response: ensure adequate symptom relief without excessive use.
• Avoid overuse: limit rescue inhalations to recommended frequency to prevent tolerance.
• Caution in pregnancy: discuss potential risks and benefits with a healthcare professional.
• Store at ambient temperature: keep below 25°C, protect from moisture and direct sunlight.
