People experiencing bronchospasm due to the β 2 receptor-blocking effects of nonselective beta blockers may be treated with anticholinergic drugs, such as ipratropium, which are safer than beta agonists in patients with cardiovascular disease. Other antidotes for beta blocker poisoning are salbutamol and isoprenaline.
Sodium channel blockers are used in the treatment of cardiac arrhythmia. They are classified as "Type I" in the Vaughan Williams classification. Class I antiarrhythmic agents interfere with the (Na +) channel. Class I agents are grouped by their effect on the Na + channel, and by their effect on cardiac action potentials.
The progress in β-blocker development led to the introduction of drugs with variety of properties. β-blockers were developed having a relative selectivity for cardiac β1-receptors (for example metoprolol and atenolol), partial adrenergic agonist activity (pindolol), concomitant α-adrenergic blocking activity (for example labetalol and ...
