Sample Use Guides

In Vivo Use Guide
For treatment of hypertension and angina pectoris the initial dose of TENORMIN is 50 mg given as one tablet. If an optimal response is not achieved, the dosage should be increased to TENORMIN 100 mg given as one tablet a day. In patients with definite or suspected acute myocardial infarction, treatment with TENORMIN I.V. Injection should be initiated as soon as possible after the patient's arrival in the hospital and after eligibility is established. Such treatment should be initiated in a coronary care or similar unit immediately after the patient's hemodynamic condition has stabilized. Treatment should begin with the intravenous administration of 5 mg TENORMIN over 5 minutes followed by another 5 mg intravenous injection 10 minutes later.

In Vitro Use Guide
Binding of alprenolol to beta adrenergic receptors was measured using [3H]CGP 12177 as a radioligand in the ranges of 0.71-3.14 nM, and whole CHO cells, expressing beta1, beta2 and beta3 adrenergic receptors. Alprenolol inhibits binding of log Kd of -7.95, -9.3 and -6.86 for beta1, 2 and 3 respectively.
