Study Notes
- Ipratropium and Tiotropium are used as inhalational drugs in the treatment of asthma and COPD.
- Adverse effects of these drugs include constipation, dry mouth, decreased sweating, dilated pupils, urinary retention, precipitation of glaucoma, decreased lacrimation, and tachycardia.
- Cooling agents and seizure control medications (diazepam) are used in the treatment of toxicity from these drugs.
- Contraindications to the use of anticholinergics include BPH, myasthenia gravis, glaucoma, and tachydysrhythmias.
- Reading assignment topics include ganglionic blockers, neuromuscular blockers, and the pharmacology of the adrenergic nervous system.
- Adrenergic receptors include α1, α2, β1, β2, and β3, with different locations and effects on smooth muscles, heart, and lipocytes.
- Adrenergic agonists exhibit different degrees of selectivity for specific receptor subtypes.
- Long-acting β2-selective agonists, such as formoterol and salmeterol, are used in the treatment of asthma and COPD.
- β2-Selective agonists, such as ritodrine, have adverse effects including tremor, restlessness, anxiety, tachycardia, and increased bronchial hypersensitivity.
- Indirect-acting sympathomimetic drugs, such as ephedrine and amphetamine, are taken up into nerve terminals and displace norepinephrine, leading to various pharmacological effects.
- Non-selective β-receptor antagonists inhibit bronchial smooth muscle relaxation, while decreasing aqueous humor production in the eye and interfering with counter-regulatory metabolic effects.
- β1-selective antagonists are preferred in the treatment of hypoglycemia, as they are less likely to delay recovery.
- Cardiovascular diseases, including angina pectoris, myocardial infarction, dysrhythmias, heart failure, and hypertension, are treated with β-blockers.
- β-blockers are also used in the treatment of chronic open-angle glaucoma and as an adjunct to definitive treatment for thyrotoxicosis.
