Interestingly, the fall was not related to smoking or to atopic status, suggestive of resting beta-adrenergic bronchodilator activity in nonasthmatic subjects.

Inderide should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Pathologic changes in the parathyroid gland with hypercalcemia and hypophosphatemia have been observed in a few patients on prolonged thiazide therapy. The common complications of hyperparathyroidism, such as renal lithiasis, bone resorption, and peptic ulceration, have not been seen. Interference with adequate oral electrolyte intake will also contribute to hypokalemia.
International Patients
Propranolol did not have an effect on the pharmacokinetics of fluvastatin. The mean Cmax and AUC of nifedipine are increased by 64% and 79%, respectively, by co-administration of propranolol. The AUC of propafenone is increased by more than 200% by co-administration of propranolol. The mechanism of the antimigraine effect of propranolol has not been established.

Inderal is indicated as an adjunct to alpha-adrenergic blockade to control blood pressure and reduce symptoms of catecholamine-secreting tumors.
