|
Agonist which can cause a1 mediated smooth muscle contraction, B1 mediated cardiac stimulation and B2 mediated bonchiol smooth muscle relaxation. |
Adrenaline |
|
|
a2 agonist which inhibits NA release and is used to treat hypertension and withdrawal symptoms. Common side effects include xerostomia. |
Clonidine |
|
|
B1 selective agonist used to treat heart failure |
Dobutamine |
|
|
Selective B2 agonist used to treat asthma. |
Salbutamol |
|
|
B2/B3 agonist which causes bronchodilation and increased metabolism. Used to treat asthma and causes weight loss and muscle gain. Increases muscle bulk in athletes and livestock. |
Clenbuterol |
|
|
Selective a1 antagonist which causes vasodilation and decreased vascular resistance - used to treat hypertension. Side effects include: orthostatic or postural hypotension due to some loss in sympathetic reflex. |
Prazosin |
|
|
B1/B2 antagonist used to treat hypertension and angina. Decreases cardiac output and also decreases oxygen demand (but blocking B2 causes bronchoconstriction, therefore contra-indicative in asthmatics) |
Propranolol |
|
|
Selective B1 antagonist used to treat hypertension and angina. Could cause rebound hypertension/angina on abrupt withdrawal due to B1 receptor supersensitivity. |
Atenolol |
|
|
Selective B2 antagonist used to treat glaucoma - causes ciliary muscles to contract and decrease intraocular pressure. |
Timolol |
