# Aclidinium Bromide
*(Note: "Walethmade" is not a recognized pharmaceutical entity; based on the suffix, this information reflects **Aclidinium Bromide**, a long-acting muscarinic antagonist (LAMA) used for COPD.)*
## Overview
Aclidinium bromide is a long-acting inhaled anticholinergic (bronchodilator) that works by inhibiting M3 receptors in the airway smooth muscle. It is typically administered via a dry powder inhaler (DPI).
## Primary Indications
Maintenance treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema.
## Adult Dosing
400 mcg (one inhalation) via the Genuair/Pressair inhaler twice daily (every 12 hours). Do not exceed 800 mcg/day.
## Pediatric Dosing
Not indicated for pediatric use. Safety and efficacy in patients <18 years have not been established.
## Dose Adjustments
No specific dosage adjustments are required for renal or hepatic impairment.
## Contraindications
Hypersensitivity to aclidinium bromide, atropine, or related derivatives. Acute bronchospasm (not for rescue therapy).
## Adverse Effects
* **Common:** Headache, nasopharyngitis, cough, sinusitis.
* **Serious:** Paradoxical bronchospasm, urinary retention, narrow-angle glaucoma exacerbation, dry mouth, and tachycardia.
## Key Drug Interactions
Avoid concomitant use with other anticholinergic-containing medications (e.g., tiotropium, ipratropium) due to the risk of additive anticholinergic systemic effects.
## Monitoring
* Monitor for signs of paradoxical bronchospasm post-administration.
* Monitor for worsening of urinary retention or ocular symptoms (blurred vision, eye pain) in susceptible patients.
* Assess COPD symptom severity and lung function (FEV1) periodically.
## Clinical Pearls
* **Rescue Inhaler:** Aclidinium is **not** a rescue medication. Ensure the patient has a short-acting beta-agonist (e.g., albuterol) for acute exacerbations.
* **Inhalation Technique:** The patient must inhale deeply and forcefully through the device. The device includes a "colored control window" that changes from red to green to confirm correct inhalation.
* **Systemic Absorption:** While systemic absorption is low, anticholinergic side effects may occur; counsel patients to remain cautious if they have pre-existing bladder neck obstruction or narrow-angle glaucoma.
