Study Notes
Bronchodilators
- Albuterol, a short-acting beta-2 agonist, is commonly used to treat asthma and COPD
- Ipratropium is an anticholinergic that blocks the action of acetylcholine at muscarinic receptors, which are found in the smooth muscle of the airways
Antihypertensives
- Calcium channel blockers, such as Amlodipine and Diltiazem, limit intracellular calcium, promoting vasodilation of arterioles
- Amlodipine has few drug interactions and is primarily used to treat hypertension
- Diltiazem interacts with many other drugs and is used to treat hypertension and other cardiac dysfunctions
- Direct vasodilators, like Hydralazine, mimic the effects of nitric oxide on vascular smooth muscle, leading to relaxation of smooth muscle
Smooth Muscle Relaxants
- Nitric oxide donors, such as Nitroglycerin, are used to treat angina and heart failure by releasing nitric oxide in vascular smooth muscle
- Phosphodiesterase inhibitors, like Sildenafil, inhibit the enzyme that breaks down cGMP, which increases cGMP levels, enhancing and prolonging erections in response to sexual stimulation
Prostaglandins
- Misoprostol is a prostaglandin analog that mimics the action of naturally occurring prostaglandins, and is used to induce labor by promoting uterine contraction
Agents for Gastrointestinal Smooth Muscle
- Hyoscine, an antispasmodic, blocks the action of acetylcholine at muscarinic receptors, which leads to decreased GI motility and secretion, helping to manage conditions like irritable bowel syndrome (IBS)
