Amy's Class Notes on Pharmacology -- Adregenic and Adregenic Blocking Agents (1999)
I don't know if these will help you out but just in case, I added them onto the site.  These are just notes that I took in class in different formats. 

Adrenergic Agents

-agonists (has affinity for receptor and binds to it producing an effect).

-Direct action on receptor; indirectly acting release presynaptic NE: mixed – both

-Pharmacologic effects

* CNS                     *cardiovascular

*eye                        *respiratory

*metabolic effects *salivary glands

-Adverse reactions

*anxiety and tremors

*pt. may have palpations

*serious arrhythmias can result.

*a(alpha) adrenergic action can increase BP

-Uses

Vasoconstriction

1.        prolong action of local anesthetics via construction of blood vessels. aLso reduces toxic side effects.

2.       Homeostasis- used topically or infiltrated locally to stop bleeding in dental field but use cautiously as can be absorbed and have toxic effects.

3.       Decongestion- incorporated into nose drops or sprays (Constrict vessels and reduce swelling of nasal mucosa)

Cardiac effects

1.        treatment of shock – elevates BP, but need to correct the cause of shock.

2.       Treatment of cardiac arrest- stimulate heart.

Bronchodilation-  treat asthma, emphysema, and anaphylaxis

CNS stimulation- stimulation effects used in some diet pills, attention deficit disorder

-Special adrenergic agents (From book)

*Epinephrine                         *Phenylephrine

*Levonordefrin                     *Isoproterenol

*Ephedrine                             *Pseudoephedrine

*Dopamine                             *Dipivefrin

*Amphatimine

-DRUGS

*Ephinephrine                       * Norephinephrine

*Phenylephrine                      *Levonordefrin

*Isoproterenol                       *Ephedrine

*Pseudoephedrine                 *Dopamine

*Dipivefrine                          *Amphetamine

*Albuterol                              *Terbutaline

Adrenergic blocking agents

-antagonists (has affinity for receptor and binds to it but produces no effect).

-a(alpha)-adrenergic blocking agents

-inhibit vasoconstricting effects of adrenergic agents. 

-Reduces sympathetic tone thus decreasing TPR.

-The decrease in BP can stimulate vagus nerve and result in reflex bradycardia.

-Block myadriasis.

-B(Beta)-adrenergic blocking agents

-generic names end in –olol

-Block beta receptor stimulation and produces bradycardia, bronchoconstriction.

-Non-selective and selective drugs.

-a(alpha) and B(beta) blocking agents

-treats hypertension without reflex tachycardia.

-DRUGS

*a1 blocking- Phenoxubenzamine, Phentolamine, Prazosin, Doxazosin

*Nonselective B blocking- Propanol, Timolol

*Selective B1 blocking- metoprolol, Atenolol, Bisoprolol

*a and B blocking - Laberatol
