01 Risk first

Safety essentials

The information most likely to change a prescribing or dispensing decision.

Contraindications

  • Hypersensitivity.
  • LABA monotherapy in asthma is contraindicated — always with ICS.

Precautions

  • Paradoxical bronchospasm.
  • Hypokalaemia with high dose/nebs especially with steroids/diuretics/xanthines.
  • CV disease: tachycardia/arrhythmia risk.
  • Thyrotoxicosis caution.
02 Point of care

Dosing matrix

Population and organ-function guidance, shown together for faster comparison.

Adult

Acute attacks: 1 or 2 puffs. Prophylaxis: 2 puffs TID or QID. Exercise induced bronchospasm: 2 puffs before exertion. Children: half adult dose

Paediatric

See label paediatric section if present; otherwise use paediatric formulary — do not extrapolate adult doses.

Renal

Low for inhaled; monitor electrolytes if continuous nebs.

  • CrCl 0–120: Confirm renal dosing in product SmPC / primary label.
Hepatic

Low clinical concern for inhaled therapy.

03 Clinical use

Use, effects & interactions

Indications

  • Reversible bronchospasm associated with acute or chronic asthma, bronchitis or other obstructive pulmonary disease.
  • Clinical selection for Salbutamol inhaler should follow culture results where relevant, Kenya STG/EML recommendations, and the current product SmPC.
  • Class context: Beta-2 adrenergic agonist (bronchodilator).
  • Confirm site-specific dose, duration and monitoring before prescribing.

Adverse effects

  • Muscle cramps, tachycardia, palpitation, fine muscle tremor, headache, peripheral vasodilation, restlessness, allergic reactions, fear, fatigue, insomnia, dizziness.
  • Assess inhaler technique every visit.
  • Increasing SABA use = uncontrolled disease — step up controller therapy.
  • Never prescribe LABA alone for asthma.

Read complete mechanism

It stimulates beta-agonist receptors in the lungs to relax bronchial smooth muscle, thereby relieving bronchospasm. This action may result from increased production of cAMP and ensuing reduction in intracellular calcium concentration caused by activation of the enzyme adenylate cyclase that catalyzes the conversion ATP to cAMP. Increased cAMP concentrations, in addition to relaxing bronchial smooth muscle, inhibit release of mediators of immediate hyper-sensitivity from cells, especially from mast cells.

Pregnancy

Inhaled salbutamol widely used; uncontrolled asthma risk > drug risk.

Lactation

Inhaled therapy generally compatible.
