| The FDA approved the use and sale of this drug in February 1996. Atenolol drug is a molecule
of the class of beta-blockers, used for the treatment of hypertension, angina pectoris or myocardial infarction. US Manufacturers
introduced it in 1976; the pill was developed to replace propranolol for the treatment of hypertension. Tenormin reduces the
arrival of nerve impulses to the heart and contraction of the blood vessels, reduces the oxygen content of heart and blocks
certain functions of the sympathetic nervous system.
A beta-blocker or ß-blocker is a medicine that blocks the action of the adrenergic system mediators such adrenaline.
Beta-blockers take the place of these mediators on ß receptors, but do not provoke reaction from the receiver, or a reaction
lower than if he had received a mediator. Some ß-blockers prevent the emergence of mediators adrenergic, and indirectly oppose
their actions.
The sale of the drug Tenormin is legal and clinical trials have proved it effective. It should be ingested before meals or right before
bedtime. The prescribed dose for the treatment of high blood pressure or angina is set to 50-100 mg once daily. Heightened myocardial
infarction (heart attack) is set to be treated with two 5 mg injections controlled 10 minutes apart and followed by the treatment of
100 mg oral Atenolol for a time period of 6-9 days. In case Tenormin injections are not wise, patients might be treated with a 100 mg
dose daily, of oral Atenolol for a time span of 7 days.
