Procaterol is a type of medication that belongs to the class of drugs known as beta2-agonists. It is used in the treatment of chronic obstructive pulmonary disease (COPD) and asthma. It works by relaxing the airways which makes it easier for the person to breathe. Procaterol is also known as formoterol, and it is taken through an inhaler device. It is usually taken twice a day and should be used regularly to help keep the airways open. Side effects of procaterol may include nausea, headache, and shakiness.
Procaterol is a medication that was intended to be a long-acting beta-2 adrenergic receptor agonist for treating asthma and chronic obstructive pulmonary disease (COPD) [1, 2]. However, it has some limitations that have prevented its widespread use. Here's a closer look at its properties:
Intended Use:
- Designed to relax the muscles surrounding the airways in the lungs, similar to other bronchodilators used for asthma and COPD. This would help ease breathing difficulties associated with these conditions.
Benefits:
- In theory, procaterol could offer a benefit over some existing medications by providing a longer-lasting bronchodilator effect due to its classification as a long-acting beta-2 agonist [1].
Limitations:
- Procaterol is readily broken down by moisture and air, making it unsuitable for administration through traditional inhalation methods like metered-dose inhalers (MDIs) [2, 3].
- Pharmaceutical companies haven't been able to develop a suitable stabilizer to prevent this breakdown, hindering its practical use as an inhaled medication [3].
Current Status:
- Procaterol has never been approved by the FDA for use in the United States [3].
- Due to the instability issues, it's not widely available or commonly used anywhere in the world.
Alternatives:
- There are many other effective bronchodilator medications available, including various long-acting beta-2 agonists that can be delivered through inhalers thanks to stabilizers [2].
