What is Berotec® N (Fenoterol) Metered Aerosol?
Berotec® N (Fenoterol) is a metered-dose inhaler containing 100 mcg of Fenoterol per puff.
It is primarily used for treating respiratory conditions such as asthma and bronchitis.
Fenoterol is a selective beta2-adrenergic agonist that works by quickly relaxing the muscles in the airways, making it easier to breathe during an asthma attack or bronchospasm.
How Does Berotec® N Work?
Berotec® N contains Fenoterol, a potent bronchodilator, specifically a selective beta2-adrenergic agonist.
Its primary action is to relax the smooth muscles that line the airways in the lungs, which helps to alleviate bronchospasm, a condition where these muscles tighten and cause the airways to narrow.
This narrowing of the airways can lead to symptoms such as wheezing, shortness of breath, and difficulty breathing, which are commonly associated with asthma and other obstructive respiratory conditions.
Mechanism of Action
Activation of Beta2-Adrenergic Receptors:
- When you inhale Berotec® N, Fenoterol directly targets the beta2-adrenergic receptors located in the smooth muscle cells of the bronchi (airways in the lungs).
- Activation of these receptors triggers a cascade of biochemical events inside the muscle cells, leading to the relaxation of the smooth muscle tissue. This relaxation results in the widening (dilation) of the bronchi, allowing for improved airflow into and out of the lungs.
Rapid Onset of Action:
- Fenoterol is known for its quick onset of action. After inhalation, the drug typically begins to work within minutes, providing rapid relief from acute symptoms such as shortness of breath or wheezing. This makes Berotec® N particularly useful during an asthma attack or in situations where immediate bronchodilation is required.
Reduction of Airway Resistance:
- By relaxing the smooth muscles and dilating the airways, Fenoterol significantly reduces the resistance to airflow. This decrease in resistance makes it easier for air to move in and out of the lungs, which improves overall breathing and oxygen exchange.
Prevention of Bronchoconstriction:
- Fenoterol also helps prevent bronchoconstriction (the narrowing of the airways) that can be triggered by physical exertion, exposure to allergens, or other stimuli. This preventative action is beneficial for individuals who experience exercise-induced asthma or allergic reactions that affect their breathing.
Anti-Inflammatory Support:
- While the primary function of Berotec® N is to dilate the airways, its use can also complement anti-inflammatory treatments. In chronic conditions like asthma, inflammation is a key factor that contributes to airway obstruction. Although Fenoterol itself is not an anti-inflammatory, its bronchodilatory effect can enhance the delivery and efficacy of inhaled corticosteroids or other anti-inflammatory medications, which work to reduce swelling and inflammation in the airways over the long term.
Duration of Effect
The bronchodilatory effect of Fenoterol lasts for several hours, typically around 3 to 6 hours, depending on the individual and the severity of their condition. This duration is sufficient to manage symptoms between doses, allowing for better control of respiratory conditions throughout the day.
When Should You Use Berotec® N?
Berotec® N is indicated for:
- Symptomatic treatment of acute asthma attacks: It offers quick relief during sudden episodes of wheezing and shortness of breath.
- Prevention of exercise-induced asthma: Inhalation before physical exertion can help prevent asthma symptoms triggered by exercise.
- Management of chronic obstructive pulmonary diseases: It helps alleviate symptoms of COPD, including chronic bronchitis and emphysema, by improving airflow in the lungs.
What Should You Know Before Using Berotec® N?
Contraindications
Berotec® N should not be used if you have:
- Hypersensitivity to Fenoterol or any of the ingredients in the inhaler.
- Hypertrophic obstructive cardiomyopathy.
- Tachyarrhythmia (abnormally fast heart rhythms).
Precautions
Special care should be taken if you have:
- Severe heart conditions, especially following a recent heart attack.
- Uncontrolled high blood pressure or aneurysm.
- Thyroid disorders or poorly controlled diabetes.
- Conditions like pheochromocytoma (a rare tumor of adrenal gland tissue).
Can Berotec® N Affect the Cardiovascular System?
Yes, like other sympathomimetics, Berotec® N can impact the cardiovascular system.
Although rare, cases of myocardial ischemia (reduced blood flow to the heart) have been reported.
Patients with pre-existing severe heart conditions should use Berotec® N with caution and immediately seek medical advice if they experience chest pain or other symptoms of heart disease.
How to Use Berotec® N Correctly?
Using the inhaler properly is crucial for effective treatment.
Here are the steps:
- Remove the protective cap.
- Exhale deeply.
- Place the mouthpiece in your mouth, aiming the inhaler upwards.
- Press down on the inhaler while taking a deep breath in, hold your breath for a few seconds, and then exhale slowly.
- If another dose is needed, wait for a few minutes before repeating.
- Replace the protective cap after use.
It's essential to clean the mouthpiece at least once a week to prevent blockage.
What Are the Possible Side Effects?
Like all medications, Berotec® N can cause side effects. Common side effects include:
- Tremors, especially in the hands.
- Dizziness.
- Nausea and vomiting.
- Increased sweating.
- Nervousness or anxiety.
Less common but more severe side effects include heart arrhythmias, significant changes in blood pressure, and paradoxical bronchospasm (a sudden constriction of the airways after using the inhaler).
What to Do in Case of an Overdose?
Symptoms of overdose can be severe and include:
- Facial flushing.
- Rapid or irregular heartbeat.
- Severe headache or dizziness.
- Shaking or tremors.
- Increased blood sugar levels.
If you suspect an overdose, seek immediate medical attention.
Can Children Use Berotec® N?
Yes, Berotec® N can be used by children, but only under adult supervision and following the doctor's instructions.
The recommended dose for children between 4 to 6 years is one inhalation as needed, not exceeding four inhalations per day.
What Should Athletes Know About Berotec® N?
Athletes should be aware that Berotec® N contains Fenoterol, a beta2-adrenergic agonist, which can potentially result in a positive doping test. This substance is regulated in sports due to its ability to enhance physical performance by improving breathing and oxygen delivery.
Doping Regulations and TUE
Potential for Positive Tests: Fenoterol is monitored in sports, and exceeding certain levels can lead to a positive doping test. This could result in penalties, including disqualification.
Therapeutic Use Exemption (TUE): Athletes who need Berotec® N for legitimate medical reasons should obtain a TUE. This exemption allows them to use the medication without facing penalties, provided they stay within the prescribed dosage.
Consulting a Healthcare Provider
Athletes should consult their healthcare provider to ensure they are using Berotec® N correctly and to discuss the need for a TUE. This consultation helps avoid potential issues with anti-doping regulations while managing their respiratory condition safely.
How to Store Berotec® N?
Store Berotec® N at room temperature, away from direct sunlight and heat sources.
Avoid freezing the inhaler.
Always keep the inhaler with the cap on when not in use to prevent contamination.
