Windel ConviCap 200mcg

PRESENTATION

Windel ConviCap: Each capsule contains Salbutamol Sulphate BP equivalent to Salbutamol 200 µg inhalation powder.

DESCRIPTION

Salbutamol is a beta-2-adrenergic agonist drug which produces bronchodilatation through stimulation of beta-2-adrenergic receptors

of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to

cyclic-3\',5\'-adenosine monophosphate (cyclic AMP). Increased cyclic AMP levels are associated with relaxation of bronchial

smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.

INDICATIONS

For the relief of bronchospasm in patients with asthma or chronic obstructive pulmonary disease, and for acute prophylaxis against

exercise-induced asthma or in other situations known to induce bronchospasm.

DOSAGE & ADMINISTRATION

Adults:

For the relief of acute asthma or before exercise 400 µg (2 ConviCaps). The recommended dose for maintenance treatment or

prophylactic therapy is 400 µg (2 ConviCaps) three to four times a day. Maximum dose is 1600 µg/day.

Children:

In the treatment of episodic asthma or before exercise 200 µg (1 ConviCap). The recommended dose for maintenance treatment or

prophylactic treatment is 200 µg (1 ConviCap) three to four times a day. Maximum dose is 800 µg/day.

SIDE EFFECTS

Salbutamol may cause fine tremor of skeletal muscles (particularly the hands), palpitations and muscle cramps. Tachycardia,

tenseness, headaches and peripheral vasodilatation have been reported after large doses.

PRECAUTIONS

Salbutamol should be used with caution in patients with hyperthyroidism, cardiovascular disease, occlusive vascular disorders,

hypertension and aneurysms. Hypokalaemia associated with high doses of Salbutamol may result in increased susceptibility to

digitalis-induced cardiac arrhythmias. Tachyphylaxis with resistance may occur with prolonged use of high dosage. Care is

necessary when treating patients with diabetes mellitus or closed-angle glaucoma, and in those receiving antihypertensive therapy.

USE IN PREGNANCY & LACTATION

Pregnancy:

The drug should be used during pregnancy only if the potential benefit justifies the potential risk of the fetus.

Lactation:

It is not known whether this drug is excreted in human milk. Because of the potential of tumorigenecity shown for Salbutamol in

some animal studies, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the

importance of the drug to the mother.

DRUG INTERACTION

Salbutamol should be administered with extreme caution to patients being treated with MAO inhibitors or tricyclic antidepressants

since the action of Salbutamol on the cardiovascular system may be potentiated. Beta-adrenergic blocking drugs, especially the

noncardioselective ones; may effectively antagonize the action of Salbutamol.

OVER DOSE

The symptoms with overdose are angina, headache, nausea, vomiting, tremor etc. The preferred antidote for overdosage with

Salbutamol is a cardio-selective beta-blocking agent but beta-blocking drugs should be used with caution in patients with a

history of bronchospasm.
