Clinical monograph: fenoterol
BNF-referencedFenoterol is a selective beta-2 adrenergic agonist used primarily as a bronchodilator in the management of respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It acts by stimulating beta-2 receptors in the bronchial smooth muscle, leading to relaxation and dilation of the airways, thus facilitating easier breathing.
Indications
- Asthma
- Chronic obstructive pulmonary disease (COPD)
- Bronchospasm
Dosage
Children: Refer to the BNF for Children for specific dosing recommendations.
Adults: Refer to the BNF for specific dosing recommendations.
Mechanism of action
Fenoterol stimulates beta(2)-adrenergic receptors in the lung, which causes relaxation of bronchial smooth muscle, resulting in bronchodilation and increased bronchial airflow.
Pharmacodynamics
Fenoterol is a beta agonist designed to open up the airways to the lungs by decreasing bronchoconstriction. By activating beta-2 receptors, it enhances airflow and reduces airway resistance, making it effective in relieving symptoms of bronchospasm.
Pharmacokinetics
Fenoterol is rapidly absorbed after inhalation, with peak plasma concentrations typically occurring within 1 to 2 hours. It has a half-life of approximately 3 to 6 hours. The drug is metabolized in the liver and excreted primarily in the urine, with renal clearance being a significant pathway for its elimination.
Adverse effects
- Tachycardia
- Palpitations
- Tremor
- Headache
- Dizziness
- Nausea
- Muscle cramps
Precautions
- Use with caution in patients with cardiovascular disease
- Monitor in patients with hyperthyroidism
- Caution in patients with diabetes mellitus due to potential hyperglycemia
Pregnancy
Use only if clearly needed and the benefits outweigh the risks, as limited data are available on the safety of fenoterol during pregnancy.
Breast-feeding
Fenoterol is excreted in breast milk, therefore caution should be exercised when administering to breastfeeding women.
Storage
Store at room temperature, away from moisture and heat. Keep out of reach of children.
