Oxis Turbuhaler (Formoterol Fumarate Dihydrate)

Formoterol fumarate dihydrate, the active ingredient in Oxis Turbuhaler, is a long‑acting β‑adrenergic agonist (LABA) presented as a dry‑powder inhalation formulation for oral inhalation use. It provides bronchodilation for maintenance therapy in asthma and chronic obstructive pulmonary disease (COPD) in adults.

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

Formoterol fumarate dihydrate is a bronchodilator that acts on the airway smooth‑muscle pathway to improve airflow. - Asthma: improves lung function and reduces symptoms when used regularly as maintenance therapy. - Chronic obstructive pulmonary disease (COPD): provides sustained bronchodilation to ease breathing and decrease exacerbation risk. - Exercise‑induced bronchoconstriction: helps prevent airway narrowing during physical activity when combined with a rapid‑onset reliever.

Formoterol may cause adverse reactions that vary in frequency and severity.

Common Side Effects: - Tremor: mild shaking of the hands or limbs. - Headache: transient headache episodes. - Throat irritation: discomfort or dryness in the throat. - Cough: occasional coughing after inhalation. - Palpitations: sensation of rapid or irregular heartbeat.

Serious or Rare Side Effects: - Paradoxical bronchospasm: sudden worsening of breathing difficulty. - Cardiovascular events: chest pain, arrhythmia, or hypertension. - Hypokalemia: low blood potassium levels. - Severe allergic reaction: rash, swelling, or anaphylaxis.

When prescribing Formoterol, clinicians should consider several safety aspects. - Assess asthma or COPD control: ensure patient is stable before initiating therapy. - Review cardiovascular history: patients with arrhythmias or ischemic heart disease need careful monitoring. - Avoid excessive dosing: do not exceed the recommended daily inhalations. - Monitor for paradoxical bronchospasm: discontinue if breathing worsens after use. - Store at ambient temperature: keep below 25°C, retain in original packaging, and protect from moisture.

Formoterol can interact with other medications that affect the cardiovascular or respiratory systems.

Major Interactions (Avoid):\n- Non‑selective β‑blockers: antagonize bronchodilator effect and may precipitate bronchospasm. - Mono‑mono    t -   t   -      \
