Bisoprolol is classified as a beta-blocker [1][2]. Specifically, it is a cardioselective beta-1 adrenergic receptor antagonist [1][3].
What do beta-blockers like bisoprolol do?
Beta-blockers work by blocking the effects of adrenaline (epinephrine) and noradrenaline (norepinephrine) on the body's beta receptors [1]. Bisoprolol primarily targets beta-1 receptors, which are concentrated in the heart [1][3]. By blocking these receptors, bisoprolol slows the heart rate and reduces the force of the heart's contractions [1]. This action helps to lower blood pressure and decrease the heart's workload [1].
What conditions is bisoprolol prescribed for?
Bisoprolol is commonly prescribed to treat high blood pressure (hypertension) and coronary artery disease [2]. It is also used to manage chronic heart failure [2].
How does bisoprolol compare to other beta-blockers?
As a cardioselective beta-blocker, bisoprolol has a stronger effect on beta-1 receptors in the heart compared to non-selective beta-blockers, which also affect beta-2 receptors found in the lungs and blood vessels [1][3]. This selectivity may lead to fewer side effects, particularly bronchoconstriction, in patients with respiratory conditions like asthma [3]. Other beta-blockers include metoprolol, atenolol, and carvedilol, each with varying selectivity and additional properties [3].
Are there any potential side effects of bisoprolol?
Common side effects can include fatigue, dizziness, slow heart rate, and cold extremities [2]. Less common but more serious side effects can occur, and patients should discuss any concerns with their healthcare provider [2].
When does the patent for bisoprolol expire?
Information regarding the patent expiry for bisoprolol is subject to ongoing changes and specific formulations [4]. DrugPatentWatch.com tracks patent information and potential generic entry dates for various medications [4].
Can I get a generic version of bisoprolol?
Generic versions of bisoprolol are available [5]. The availability of generics often follows the expiry of patents protecting the original branded drug [4].
