Salbutamol sulfate & Ipratropium bromide solution for inhalation in ampoule may be administered from a suitable nebulizer or an intermittent positive pressure ventilator.

• Adults (including elderly): Use one 3 ml ampoule in the nebulizer four times a day. Two additional treatments may be used per day, if needed.
• Children: Use and dose must be determined by doctor.

Patients should be advised to consult a doctor or the nearest hospital immediately in the case of acute or rapidly worsening dyspnoea if additional inhalations do not produce an adequate improvement.

In common with other beta-agonists containing products, side effects of this solution can include fine tremor of skeletal muscles and nervousness and less frequently tachycardia, dizziness, palpitations or headache, especially in hypersensitive patients.

Potentially serious hypokalaemia may result from prolonged and/or high dose beta2 agonist therapy.

As with use of other inhalation therapy, cough, local irritation and less commonly inhalation induced bronchospasm can occur. As with other beta-mimetics, nausea, vomiting, sweating, weakness and myalgia/muscle cramps may occur. In rare cases decrease in diastolic blood pressure, increase in systolic blood pressure, arrhythmias, particularly after higher doses, may occur.

In individual cases psychological alterations have been reported under inhalation therapy with beta-mimetics.

The most frequent non-respiratory anticholinergic related adverse events are dryness of mouth and dysphonia. There have been isolated reports of ocular complications (i.e. mydriasis, increased intraocular pressure, angle closure glaucoma, and eye pain) when aerosolised ipratropium bromide either alone or in combination with adrenergic beta2 agonist, has escaped into the eyes. Ocular side effects, gastrointestinal motility disturbances and urinary retention may occur in rare cases and are reversible.

The effects of overdosage are expected to be primarily related to Salbutamol because acute overdosage with Ipratropium Bromide is unlikely as it is not well absorbed systemically after inhalation or oral administration.

Symptoms: Manifestations of overdosage with salbutamol may include tachycardia, anginal pain, hypertension, hypotension , palpitations, tremor, widening of the pulse pressure, arrhythmia and flushing.

Therapy: Administration of sedatives, tranquillisers; in severe cases, intensive therapy. Beta-receptor blockers, preferably beta1-selective, are suitable as specific antidotes; however, a possible increase in bronchial obstruction must be taken into account and the dose should be adjusted carefully in patients suffering from bronchial asthma.

Salbutamol sulfate & Ipratropium bromide solution for inhalation is indicated for the treatment of reversible bronchospasm associated with obstructive airway diseases in patients who require more than a single bronchodilator.

Ipratropium Bromide is quickly absorbed after inhalation. The systemic bioavailability following inhalation is estimated to be less than 10% of the dose. Renal excretion of Ipratropium Bromide is given as 46% of the dose after intravenous administration. The half-life of the terminal elimination phase is about 1.6 hours as determined after intravenous administration. Elimination half-life of drug and metabolites is 3.6 hours as determined after radio labelling. Ipratropium Bromide does not penetrate the blood brain barrier.

Salbutamoi Sulphate is rapidly and completely absorbed following administration either by inhaled or oral route. Peak plasma Salbutamoi concentrations are seen within three hours of administration and it is excreted unchanged in the urine after 24 hours. The elimination half-life is 4 hours. Salbutamoi will cross the blood brain barrier reaching concentrations amounting to about five percent of the plasma concentrations.

It has been shown that co-nebulisation of Ipratropium Bromide and Salbutamoi Sulphate does not potentiate the systemic absorption of either component and that therefore the additive activity of this solution is due to the combined local effect on the lung following inhalation.

In the case of acute, rapidly worsening dyspnoea a doctor should be consulted immediately. Immediate hypersensitivity reactions may occur after administration of this solution as demonstrated by rare cases of urticaria, angioedema, rash, bronchospasm and oropharyngeal oedema.
