2. -adrenergic agonist. Beta2-adrenergic agonists, also known as adrenergic β2 receptor agonists, are a class of drugs that act on the β 2 adrenergic receptor. Like other β adrenergic agonists, they cause smooth muscle relaxation. β 2 adrenergic agonists' effects on smooth muscle cause dilation of bronchial passages, vasodilation in muscle ...
The beta-2 adrenergic receptor (β 2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that binds epinephrine (adrenaline), a hormone and neurotransmitter whose signaling, via adenylate cyclase stimulation through trimeric G s proteins, increases cAMP, and, via downstream L-type calcium channel interaction, mediates physiologic responses such as smooth ...
Betamethasone is a steroid medication. It is used for a number of diseases including rheumatic disorders such as rheumatoid arthritis and systemic lupus erythematosus, skin diseases such as dermatitis and psoriasis, allergic conditions such as asthma and angioedema, preterm labor to speed the development of the baby's lungs, Crohn's disease, cancers such as leukemia, and along with ...
β 2 -adrenoceptor agonists are a group of drugs that act selectively on β 2 -receptors in the lungs causing bronchodilation. β 2 -agonists are used to treat asthma and COPD, diseases that cause obstruction in the airways. Prior to their discovery, the non-selective beta-agonist isoprenaline was used. The aim of the drug development through ...
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 ...

Beta blocker. Skeletal formula of propranolol, the first clinically successful beta blocker. Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms ( arrhythmia ), and to protect the heart from a second heart attack after a first heart attack ( secondary prevention ).

Clobetasol propionate. Clobetasol propionate is a corticosteroid used to treat skin conditions such as eczema, contact dermatitis, seborrheic dermatitis, and psoriasis. [3] It is applied to the skin as a cream, ointment, or shampoo. [3] [4] Use should be short term and only if other weaker corticosteroids are not effective. [4]
A beta-lactam ( β-lactam) ring is a four-membered lactam. [1] A lactam is a cyclic amide, and beta -lactams are named so because the nitrogen atom is attached to the β-carbon atom relative to the carbonyl. The simplest β-lactam possible is 2-azetidinone. β-lactams are significant structural units of medicines as manifested in many β-lactam ...
Calcipotriol. Calcipotriol, also known as calcipotriene, is a synthetic derivative of calcitriol, a form of vitamin D. It is used in the treatment of psoriasis. [1] It is safe for long-term application in psoriatic skin conditions. [medical citation needed] It was patented in 1985 and approved for medical use in 1991. [2]
