Exacerbation of angina and, in some cases, myocardial infarction and ventricular dysrhythmias have been reported after abrupt discontinuation of therapy with beta-adrenergic blocking agents in patients with coronary artery disease. Abrupt withdrawal of these agents in patients without coronary artery disease has resulted in transient symptoms, including tremulousness, sweating, palpitation, headache, and malaise. Several mechanisms have been proposed to explain these phenomena, among them increased sensitivity to catecholamines because of increased numbers of beta receptors.

In animals, at doses greater than those required for alpha-or beta-adrenergic blockade, a membrane stabilizing effect has been demonstrated. Administration of benzodiazepines diazepam is one of the first line treatments for cocaine overdose. Benzodiazepines produce an increase in GABA-A mediated chloride current, which hyperpolarizes neurons and produces widespread inhibition within the CNS. This can suppress local anesthetic-induced seizure activity, and may reduce the CNS-mediated component of cocaine's systemic effects including the cocaine-induced increase in sympathetic outflow.

Manufactured in Canada by WellSpring Pharmaceutical Canada Corp. Although beta-adrenergic receptor blockade is useful in the treatment of angina and hypertension, there are also situations in which sympathetic stimulation is vital. For example, in patients with severely damaged hearts, adequate ventricular function may depend on sympathetic drive. Beta-adrenergic blockade may worsen A-V block by preventing the necessary facilitating effects of sympathetic activity on conduction. Beta 2-adrenergic blockade results in passive bronchial constriction by interfering with endogenous adrenergic bronchodilator activity in patients subject to bronchospasm, and it may also interfere with exogenous bronchodilators in such patients.

Potential Adverse Effects: In addition, other adverse effects not listed above have been reported with other beta-adrenergic blocking agents. Zimmerman, 1985. In addition prazosin has no effect on the presynaptic α 2 receptors in sympathetic nerve endings that innervate the heart. As a result, any changes in sympathetic tone to the heart are minimized due to activation of negative feedback. In contrast, the blood pressure lowering effects of non-selective alpha blockers, such as phentolamine, are associated with a marked reflex tachycardia due to blunting of inhibitory presynaptic α 2 feedback that suppresses the release of norepinephrine when synaptic levels of the neurotransmitter rise. protopic-ointment
