In the 3-adrenergic blocking drug pyrroxan (48), the catechol moiety is masked in a doxane ring. The synthesis begins by alkylation of phenyl acetonitrile by 2-chloroethanol to produce alcohol Recuction converts this to amino alcohol which... 

List the four types of adrenergic blocking drugs. 

Discuss the uses, general drug actions, general adverse reactions, contraindications, precautions, and interactions of the adrenergic blocking drugs. 

Discuss important preadministration and ongoing assessment activities the nurse should perform on the patient taking adrenergic blocking drugs. 

Discuss ways to promote an optimal response to therapy, how to manage common adverse reactions, nursing actions that may be taken to minimize orthostatic or postural hypotension, and important points to keep in mind when educating patients about the use of adrenergic blocking drugs.

Administration of an a-adrenergic blocking drug may result in weakness, orthostatic hypotension, cardiac arrhythmias, hypotension, and tachycardia... 

Older adultsare at increased risk for adverse reactions when taking the (3-adrenergic blocking drugs The nurse should monitor the older adult closely for confusion, heart failure, worsening of angina, shortness of breath, and peripheral vascular insufficiency (eg, cold extremities paresthesia of the hands weak peripheral pulses). 

These dm are primarily used in the treatment of hypertension (see the Summary Drug Table Adrenergic Blocking Drugs also see Chap. 39) and certain cardiac arrhythmias (abnormal rhythm of the heart), such as ventricular arrhythmias or supraventricular tachycardia They are used to prevent reinfarction in patients with a recent myocardial infarction (1—4 weeks after MI). Some of these dm have additional uses, such as the use of propranolol for migraine headaches and nadolol for angina pectoris. 

The Patient Receiving an Adrenergic Blocking Drug ASSESSMENT... 

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. 

In addition, when an adrenergic blocking drug is prescribed for hypertension, the primary care provider may want the patient to monitor his or her own blood pressure between office visits. This may enable the number of visits to the primary care provider office to be reduced and will help the patient learn to manage his or her own health (see Fhtient and Family Teaching Checklist Monitoring Blood Pressure). 

A new nurse says that she is unsure about how the adrenergic blocking drugs work. Discuss the four types of adrenergic blocking drugs and how each one works within the body. 

When an adrenergic blocking drug is given for a life-threatening cardiac arrhythmia, which of the following activities would die nurse expect to be a part of patient care ... 

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...
