Onsudil (Procaterol Hydrochloride)

Procaterol hydrochloride, the active ingredient in Onsudil, is a short‑acting β2‑adrenergic agonist presented as a inhalation solution for oral inhalation use. It is used to relieve bronchospasm in patients with reversible airway obstruction such as asthma.

GNH USA supplies Onsudil as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals and pharmacies worldwide.

Onsudil is a β‑adrenergic bronchodilator that acts on the airway smooth‑muscle pathway to improve airflow.

- Asthma: Provides rapid relief of bronchospasm and improves peak expiratory flow. - Chronic obstructive pulmonary disease (COPD): Helps alleviate reversible airway narrowing during exacerbations. - Exercise‑induced bronchoconstriction: Prevents airway narrowing associated with physical activity.

Adverse reactions reported with β2‑agonist inhalation therapy vary in frequency and severity.

Common Side Effects: - Tremor: Mild, transient shaking of the hands or limbs. - Headache: Light‑to‑moderate headache occurring shortly after inhalation. - Palpitations: Noticeable but usually benign increase in heart rate. - Throat irritation: Mild discomfort or dryness in the throat. - Cough: Temporary coughing following inhalation of the aerosol. - Nausea: Mild stomach upset or queasiness.

Serious or Rare Side Effects: - Paradoxical bronchospasm: Worsening of airway obstruction after use. - Severe tachycardia: Markedly elevated heart rate that may require medical attention. - Hypokalemia: Low blood potassium levels, potentially leading to muscle weakness. - Allergic reaction: Rash, itching, swelling, or anaphylaxis in rare cases.

When prescribing Onsudil, clinicians should consider several safety aspects.

- Cardiac monitoring: Patients with known heart disease should be observed for arrhythmias. - Electrolyte assessment: Check serum potassium in patients at risk of hypokalemia. - Diabetes management: Monitor blood glucose as β2‑agonists may affect glycemic control. - Pregnancy and lactation: Use only if the potential benefit outweighs risk. - Pediatric use: Dose adjustments may be required for children. - Store at ambient temperature: Keep below 25°C, in the original container, protected from moisture.

Procateryl may interact with several drug classes, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid): - Non‑selective β‑blockers: Antagonize the bronchodilatory effect of β2‑agonists. - Mono‑Mono‑Methyl  ---
