Orciprenaline[edit]
Orciprenaline, also known as metaproterenol, is a bronchodilator medication used in the treatment of asthma and other conditions involving reversible airway obstruction. It is a beta-adrenergic agonist that works by relaxing the muscles in the airways and increasing airflow to the lungs.
Pharmacology[edit]
Orciprenaline is a beta-2 adrenergic receptor agonist, which means it selectively stimulates the beta-2 adrenergic receptors in the lungs. This stimulation leads to the relaxation of bronchial smooth muscle, resulting in bronchodilation. The drug is typically administered via inhalation, allowing for direct action on the lung tissue and rapid onset of effects.
Mechanism of Action[edit]
The primary mechanism of action of orciprenaline involves the activation of adenylate cyclase through the beta-2 adrenergic receptors. This activation increases the levels of cyclic adenosine monophosphate (cAMP) within the cells, leading to the relaxation of bronchial smooth muscle and subsequent bronchodilation. This process helps alleviate symptoms of bronchospasm associated with conditions like asthma.
Clinical Uses[edit]
Orciprenaline is used in the management of:
- Asthma
- Chronic obstructive pulmonary disease (COPD)
- Other conditions involving reversible airway obstruction
It is often prescribed for patients who require a fast-acting bronchodilator to relieve acute symptoms of bronchospasm.
Side Effects[edit]
Common side effects of orciprenaline may include:
These side effects are generally mild and transient. However, patients with cardiovascular conditions should use orciprenaline with caution due to its potential to increase heart rate and blood pressure.
Administration[edit]
Orciprenaline is available in various forms, including:
The inhalation route is preferred for rapid relief of acute bronchospasm, while oral forms may be used for maintenance therapy.
