ATC code C07 Beta blocking agents is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. [1] [2] [3] Subgroup C07 is part of the anatomical group C Cardiovascular system. [4]
Atenolol is a beta blocker medication primarily used to treat high blood pressure and heart-associated chest pain. [7] Although used to treat high blood pressure, it does not seem to improve mortality in those with the condition.
The combination of beta blockers and antihypertensive drugs will work on different mechanism to lower blood pressure. [17] For example, the co-administration of beta-1 blocker atenolol and ACE inhibitor lisinopril could produce a 50% larger reduction in blood pressure than using either drug alone. [18]
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 ...
Antihypertensive agents comprise multiple classes of compounds that are intended to manage hypertension (high blood pressure). Antihypertensive therapy aims to maintain a blood pressure goal of <140/90 mmHg in all patients, as well as to prevent the progression or recurrence of cardiovascular diseases (CVD) in hypertensive patients with established CVD. [2]
Betaxolol also shows greater affinity for beta 1 receptors than metoprolol. In addition to its effect on the heart, betaxolol reduces the pressure within the eye ( intraocular pressure ). This effect is thought to be caused by reducing the production of the liquid (which is called the aqueous humor ) within the eye.
An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
Additionally, beta 1 blockers can affect beta 2 receptors, particularly at high doses, and hence should not be administered to patients with peripheral vascular disease or diabetes mellitus as they may cause vasoconstriction or a delayed hypoglycaemic response, respectively. [4]
