Sulprex Inhalation Aerosol (Salbutamol and Ipratropium Bromide)

Indications

Sulprex Inhalation Aerosol is indicated for use in patients with Chronic Obstructive Pulmonary Disease (COPD) who:

1. Are already on a regular aerosol bronchodilator.

2. Continue to show evidence of bronchospasm.

3. Require a second bronchodilator.

Pharmacology and Action

This aerosol is an environmentally friendly, HFA-based inhaler (does not contain CFCs). It contains two bronchodilator drugs that work via different mechanisms to maximize the treatment response:

• Salbutamol (B2-adrenergic bronchodilator): A short-acting sympathomimetic that relaxes bronchial smooth muscle.

• Ipratropium Bromide (Anticholinergic bronchodilator): Prevents bronchoconstriction caused by acetylcholine binding to muscarinic receptors.

The combination of these two distinct mechanisms (sympathomimetic and anticholinergic) provides a greater bronchodilatory effect than using either drug alone.

Dosage and Administration

• Adult Dose (Including the Elderly):2 puffs of Sulprex 4 times a day.

• Maximum: Patients may take additional puffs as required, but the total number of puffs should not exceed 12 in 24 hours.

Important Administration Steps:

• Shake the inhaler vigorously at least six times before each use.

• Breathe out fully, then place the mouthpiece in your mouth and close your lips around it.

• While breathing in deeply and slowly through the mouth, press down fully on the canister to release medicine.

• Hold your breath for at least 10 seconds (or as long as comfortable).

• If more than one puff is prescribed, wait 1 minute between puffs and shake the inhaler again.

• Rinse your mouth with water after each treatment to reduce the risk of side effects.

Contraindications and Safety

• Contraindications: Hypersensitivity to Soya-Lecithin, related food products (soybean and peanut), or to atropine or its derivatives.

• Special Populations Caution: Use with caution in patients with narrow-angle glaucoma, prostatic hypertrophy, or bladder-neck obstruction (due to Ipratropium Bromide). Use caution in patients with convulsive disorders, hyperthyroidism, or diabetes mellitus (due to Salbutamol).

• Overdose: Effects are mainly related to Salbutamol and may include anginal pain, hypertension, hypokalemia, and tachycardia.

• Side Effects: Common side effects include mild tremor and headache (usually disappear with continued treatment).

Pregnancy & Lactation: Use during pregnancy only if the potential benefit justifies the risk to the fetus. Use cautiously in nursing mothers.

Therapeutic Class: Combined bronchodilators.
