  2. Beta blocker - Wikipedia

    en.wikipedia.org/wiki/Beta_blocker

    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 ...

    Additional hypotensive effects may occur when patients are taking beta-1 blockers with other antihypertensive drugs such as nitrates, PDE inhibitors, ACE inhibitors and calcium channel blockers. [17] The combination of beta blockers and antihypertensive drugs will work on different mechanism to lower blood pressure. [17]

    When combined with inhaled steroids, β adrenoceptor agonists can improve symptoms. [1] [2] In children this benefit is uncertain and they may be potentially harmful. [2]They should not be used without an accompanying steroid due to an increased risk of severe symptoms, including exacerbation in both children and adults. [3]

    Metoprolol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a selective antagonist of the β 1-adrenergic receptor and has no intrinsic sympathomimetic activity. [37] Metoprolol exerts its effects by blocking the action of certain neurotransmitters, specifically adrenaline and noradrenaline.

    en.wikipedia.org/wiki/Beta-2_adrenergic_antagonist

    A Beta-2 adrenergic antagonist (β 2-adrenoceptor antagonist) is an adrenergic antagonist which blocks the beta-2 adrenergic receptors of cells, with either high specificity (an antagonist which is selective for β 2 adrenoceptors) like Butaxamine and ICI-118,551, or non-specifically (an antagonist for β 2 and for β 1 or β 3 adrenoceptors) like the non-selective betablocker Propranolol.
