What is Brimica?
Brimica Genuair is a prescription-only medication delivered via a dry powder inhaler, containing two distinct active ingredients: aclidinium bromide and formoterol fumarate dihydrate. It is approved specifically for the maintenance treatment of Chronic Obstructive Pulmonary Disease (COPD) in adult patients. COPD is a progressive lung disease that makes breathing difficult, and includes conditions like chronic bronchitis and emphysema. By relaxing the muscles of the airways and keeping them open, Brimica helps improve airflow and reduce symptoms like shortness of breath and wheezing.
It is important to understand that Brimica is a long-term treatment and should be used regularly as prescribed, not as a 'rescue' inhaler for sudden, acute attacks of breathlessness.
How Brimica works: A dual-action mechanism
The effectiveness of Brimica lies in its two active components, each targeting a different mechanism to widen the airways. This combination provides a more comprehensive and sustained bronchodilation effect than either medication alone.
- Aclidinium bromide: This is a long-acting muscarinic antagonist (LAMA). It works by blocking specific receptors in the smooth muscle cells of the lungs, preventing them from constricting. This action leads to the relaxation and opening of the airways, making breathing easier.
- Formoterol fumarate dihydrate: This is a long-acting beta-2 agonist (LABA). It binds to beta-2 receptors on the airway muscles, which signals them to relax. Like aclidinium, this effect helps to keep the airways open, but through a different pathway, complementing the LAMA action.
Proper use
For Brimica to be effective, consistent and correct use is essential. Patients should receive detailed instructions from their doctor or pharmacist on how to operate the Genuair inhaler correctly.
- Administration: Brimica is typically administered at regular intervals throughout the day as prescribed. Following a consistent schedule helps maintain a steady level of medication in the body.
- Inhalation technique: The Genuair device is breath-activated, meaning it delivers the medication as you inhale. After pressing and releasing the orange button, a strong, deep breath is required to pull the powder into the lungs. A 'click' sound confirms a correct inhalation. The control window turning red confirms the dose has been successfully delivered.
- Missed dose: If a dose is missed, it should be taken as soon as remembered. However, if it is almost time for the next scheduled dose, the missed dose should be skipped. It is important not to take more than the prescribed amount to compensate for a missed dose.
Potential side effects and precautions
Like all medications, Brimica can cause side effects. Awareness of these is important, and any persistent or severe effects should be reported to a healthcare provider.
Common side effects:
- Nasopharyngitis (inflammation of the nose and throat)
- Headache
- Cough
- Diarrhea, vomiting, or nausea
- Dry mouth
Serious side effects and warnings:
- Paradoxical bronchospasm: This is a rare but serious reaction where the inhaler causes the airways to tighten instead of relax. If this occurs, stop using Brimica and seek immediate medical attention.
- Cardiovascular effects: The formoterol component can increase heart rate and blood pressure. Patients with existing heart conditions should use this medication with caution.
- Urinary issues: The anticholinergic effect of aclidinium can cause or worsen urinary retention, especially in patients with an enlarged prostate.
- Narrow-angle glaucoma: Patients with this condition should use Brimica with caution as it can affect vision.
- Asthma: Brimica is not recommended for patients with asthma, as its safety and effectiveness have not been established for this condition.
Comparison of Brimica with other COPD inhalers
| Feature | Brimica (Aclidinium/Formoterol) | Stiolto Respimat (Tiotropium/Olodaterol) | Breo Ellipta (Fluticasone/Vilanterol) |
|---|---|---|---|
| Drug Class | LAMA/LABA | LAMA/LABA | Inhaled Corticosteroid/LABA |
| Purpose | Maintenance treatment for COPD | Maintenance treatment for COPD | Maintenance treatment for COPD |
| Inhaler Type | Dry powder inhaler (Genuair) | Metered-dose inhaler (Respimat) | Dry powder inhaler (Ellipta) |
| Potential Benefit | Combines two long-acting bronchodilators for sustained symptom relief | Combines two long-acting bronchodilators, often used for similar symptom control | Offers both a steroid and a bronchodilator for patients needing anti-inflammatory action |
| Consideration | Not for asthma. Contains lactose. | Not for asthma. Can have different side effects than other LAMA/LABA combinations. | Not for asthma. Risk of fungal mouth infection with steroid component. |

Conclusion
Brimica offers an effective dual-action bronchodilator therapy for the long-term management of COPD symptoms in adults. By combining a LAMA and a LABA, it works to consistently relax and open the airways, making it easier for patients to breathe. Correct usage via the Genuair inhaler is crucial for optimal results. While generally well-tolerated, patients should be aware of potential side effects and precautions, particularly if they have underlying conditions like heart problems or glaucoma. As with any prescription medication, patients should always follow their healthcare provider's instructions and never use Brimica to treat acute breathing emergencies or asthma.
