Beta blockers vary in their lipophilicity (fat solubility) and in turn in their ability to cross the blood–brain barrier and exert effects in the central nervous system. [76] Beta blockers with greater blood–brain barrier permeability can have both neuropsychiatric therapeutic benefits and side effects, as well as adverse cognitive effects ...
Beta blocker medications such as propranolol can trigger asthma in those who are susceptible. [85] Cardioselective beta-blockers, however, appear safe in those with mild or moderate disease. [86] [87] Other medications that can cause problems in asthmatics are angiotensin-converting enzyme inhibitors, aspirin, and NSAIDs. [88]
Non-selective beta-blockers should be avoided in people with asthma or bronchospasm as they may cause exacerbations and worsening of symptoms. [ 27 ] [ 28 ] [ 29 ] β 1 selective beta-blockers like bisoprolol have not been shown to cause an increase in asthma exacerbations, [ 28 ] and may be cautiously tried in those with controlled, mild-to ...
Bambuterol is a long-acting β adrenoceptor agonist (LABA) used in the treatment of asthma; it also is a prodrug of terbutaline. Commercially, the AstraZeneca pharmaceutical company produces and markets bambuterol as Bambec and Oxeol .
Levobunolol is a non-cardioselective beta blocker, that is, it blocks beta-1 receptors as well as beta-2 receptors. The latter type dominates in the ciliary body, where it controls aqueous humour production. Blocking this type of receptor reduces aqueous humour production, lowering intraocular pressure.
Among other drugs in the beta-blocker class, Acebutolol will provide beta-blockade effects to a lesser extent. Due to its cardioselectivity, Acebutolol is more suitable than non-cardioselective beta-blockers, in a patient with asthma or chronic obstructive pulmonary disease (COPD) who needs treatment with a beta-blocker. This cardio-specificity ...
