Propranolol ‘Inderal

When administering a /3 -adrenergic blocking drug, such as propranolol (Inderal), the nurse should take an apical pulse rate and blood pressure before giving the drug. If pulse is below 60 bpm or if systoiic blood pressure is less than 90 mm Hg, the nurse should withhold the drug and contact the primary health care provider. 

Ms. Martin has been prescribed propranolol (Inderal) for hypertension. She arrives at the outpatient dinic and tellsyou that she is having episodes of dizziness and at times feels as if she is going to faint. Discuss how you would investigate this problem and what information you could give Ms. Martin that might help her. 

Class II antiarrhythmic drugs include beta (( -adrenergic blocking drugs, such as acebutolol (Sectral), esmolol (Brevibloc), and propranolol (Inderal). These drugp also decrease myocardial response to epinephrine and norepinephrine (adrenergic neurohormones) because of their ability to block stimulation of p receptors of the... 

Beta Blockers. Beta blockers such as propranolol (Inderal) and atenolol (Tenormin) act by blocking the activity of the neurotransmitter norepinephrine. They have been nsed in the treatment of patients with panic disorder in an effort to alleviate the physical (antonomic) symptoms of the panic attack, bnt they proved no better than placebo and have no place in the treatment of panic disorder. 

The beta blocker propranolol (Inderal) has been studied in the treatment of impulsivity and appears to provide a slight benefit to some patients. It can be started at a dose of 10 mg taken three times per day and increased gradually to a maximum of 200mg/day. Side effects of propranolol include depression, fatigue, lowered blood pressure, impotence, and a worsening of symptoms in patients with asthma. 

Beta Blockers. The beta blockers, which act by interfering with noradrenergic transmission, have been used to manage aggression and other behavioral disturbances in patients who have suffered brain injury due to trauma and stroke for over 25 years. Several beta blockers have been tested including propranolol (Inderal), pindolol (Visken), nadolol (Corgard), and metoprolol (Lopressor). Fat-soluble beta blockers such as propranolol and pindolol more readily cross the blood-brain barrier and are thus better suited to managing psychiatric symptoms such as behavioral lability.

Propranolol (Inderal) is the prototype (3-blocker (see Chapter 11). It decreases the effects of sympathetic stimulation by competitive binding to (3-adrenoceptors. 

The reduction in plasma volume produced by p-blockers contrasts with the increased volume seen with other types of antihypertensives. Tolerance to the antihypertensive actions of p-blockers therefore is less of a problem than with the vasodilating drugs. An additional difference from the vasodilators is that plasma renin activity is reduced, rather than increased, by propranolol (Inderal). Orthostatic hypotension does not occur with p-blockers.

Propranolol [Inderal). Propranolol, the classic nonselective beta blocker, is approved for use in hypertension, angina pectoris, cardiac arrhythmias, and prevention of myocardial reinfarction. In addition, propranolol has been used in the prevention of vascular headache and as an adjunct to alpha blockers in treating pheochromocytoma. Propranolol is usually administered orally for the long-term management of the previously listed conditions, but it may be administered via intravenous injection for the immediate control of arrhythmias. 

Brief History. M.R. is a 48-year-old man with a history of coronary artery disease and cardiac rhythm disturbances. Specifically, he has experienced episodes of paroxysmal supraventricular tachycardia, with his heart rate often exceeding 180 beats per minute. He has been treated for several years with the nonspecific beta blocker propranolol (Inderal). Oral propranolol (60 mg/d) has successfully diminished his episodes of tachycardia. In an effort to improve his myocardial function and overall cardiovascular fitness, M.R. recently enrolled as an outpatient in a cardiac rehabilitation program. Under the supervision of a physical therapist, he attended cardiac training sessions three times each week. A typical session consisted of warm-up calisthenics, bicycle ergometry, and cool-down stretching activities. Each session lasted approximately 45 minutes. 

Beta-blockers, including carvedilol (Coreg), atenolol (Tenormin), betaxolol (Kerlone), metopro-lol (Lopressor, Toprol XL), penbutolol (Levatol), and propranolol (Inderal). 

Beta blockers, such as propranolol (Inderal , Lopressor ) and atenolol (Tenormin ), inhibit the actions of norepinephrine on nerve cells. Scientists do not know how these medications relieve migraine symptoms. Beta blockers are also used for the treatment of high blood pressure and chest pain.
