norepinephrine.and guanabenz are alpha 2 receptor agonists that produce the same effect as epinephrine and norepinephrine by inhibiting the adenylyl cyclase component of the receptor. Drugs that block the effects of epinephrine and norepinephrine on alpha 1 and alpha 2 receptors include alfuzosin and ...
Phentolamine is a long-acting adrenergic alpha-receptor blocker that increases blood flow to the skin, mucous membranes, abdominal organs, and reduces blood pressure.[6]Phentolamine works by obstructing alpha receptors in the body, which are present in the smooth muscle lining blood vessel walls. ...

Silodosin is a selective antagonist of alpha(α)-1 adrenergic receptors that binds to the α1A subtype with the highest affinity. α1-adrenergic receptors regulate smooth muscle tone in the bladder neck, prostate, and prostatic urethra: the α1A subtype accounts for approximately 75% of α1-...
oblongata, while at high doses, it directly suppresses the vomiting center, producing a powerful antiemetic effect. It inhibits the thermoregulatory center, leading to a decrease in body temperature, which can change with the external environment. It also blocks peripheral alpha-adrenergic receptors, ...
Epinephrine is a sympathomimetic catecholamine that exerts its pharmacologic effects on both alpha and beta-adrenergic receptors. It has a dose-dependent response on alpha and beta receptors that leads to different pharmacological effects in the body. ...
(5HT2) receptors, greater than its affinity for dopamine D1 and D2 receptors. Quetiapine fumarate also has high affinity for histamine receptors and alpha-1 adrenergic receptors, low affinity for alpha-2 adrenergic receptors, and minimal affinity for muscarinic or benzodiazepine receptors. It has ...
Abnormal tumor microenvironment and immune escape in multiple myeloma (MM) are associated with regulatory T cells (Tregs), which play an important role in maintaining self-tolerance and regulating the overall immune response to infection or tumor cells.
Alpha-1 blockers work by binding with alpha-1 receptors and block the attachment of catecholamines to the receptors. These medications help lower blood pressure levels by preventing the narrowing of blood vessels. Alpha-1 blockers include:
6. (6) Opiate agonism, including action of many endogenous opiate peptides, particularly those affecting mu and delta receptors. 7. (7) Agonism by certain other peptides (neurotensin, cholecystokinin). Among the major interactions of neurotransmitter systems that regulate immobility, are the ...
