  • Intal Inhaler is a prophylactic agent indicated in the management of patients with bronchial asthma.

    In patients whose symptoms are sufficiently frequent to require a continuous program of medication, Intal Inhaler is given by inhalation on a regular daily basis. (See DOSAGE AND ADMINISTRATION.) The effect of Intal Inhaler is usually evident after several weeks of treatment, although some patients show an almost immediate response.

    If improvement occurs, it will ordinarily occur within the first 4 weeks of administration as manifested by a decrease in the severity of clinical symptoms of asthma, or in the need for concomitant therapy, or both.

    In patients who develop acute bronchoconstriction in response to exposure to exercise, toluene diisocyanate, environmental pollutants, known antigens, etc., IntalInhaler should be used shortly before exposure to the precipitating factor, i.e., within 10 to 15 minutes but not more than 60 minutes. (See DOSAGE AND ADMINISTRATION.) Intal Inhaler may be effective in relieving bronchospasm in some, but not all, patients with exercise induced bronchospasm.
