The abortive treatment of choice for migraine is one of the ergot alkaloids or triptans, which are vasoconstrictors
that act upon the terminal branches of the external carotid artery.
Most studies suggested that HRS pathogenesis is associated with the vasoconstrictor
system, including excessive vasopressin secretion.
4] Use of local vasoconstrictors
can lead to endoscopic surgery is a minimally invasive technique that has found a definite place in all surgical techniques.
For using local anesthesia with vasoconstrictor
, 54% said it was safe to use during pregnancy, 30.
Blood sampling for plasma thiobarbituric acid-reactive substances (TBARS), vitamin C, soluble vascular cell adhesion molecule-1 (sVCAM-1) and E-selectin was done on enrolment and thereafter daily until vasoconstrictor
cessation and on the 7th day following cessation of vasoconstrictors
noted that patients with serum creatinine > 7 mg/dl are less likely to respond to vasoconstrictor
13] In the hypovolemic state, prostaglandins (most importantly prostaglandin E1 and or prostacyclin) oppose the action of the vasoconstrictor
autacoids to maintain renal blood flow and glomerular filtration.
This finding can also be explained by greater stimulation of the cutaneous vasoconstrictor
responses that are controlled by adrenergic nerves of the sympathetic system and most likely modulated by the action of noradrenergic neurotransmitters, such as norepinephrine and/or neuropeptide Y (4, 5, 8, 26).
Methods devised toreduce nasotracheal complications include the use of lubricants (saline, water-soluble lignocaine gel), vasoconstrictor
(oxymetazoline, cocaine, lignocaine-epinephrine/phenylephrine), lower size ETTs and warming nasotracheal tubes, although, some of these drugs may be associated with serious complications.
8 ml, Scandicaine 3% without vasoconstrictor

In earlier studies crude extracts of Dodonaea viscosa showed significant actions as local anesthetic smooth muscle relaxant antibacterial anti-inflammatory antifungal anti-ulcerogenic anti-ascariasis anthelmintic cardiac depressant hypotensive uterine relaxation and vasoconstrictor
activity in different experimental models.
Al anadir vasoconstrictor
disminuye la toxicidad sistemica, hay una hemostasia, bloqueo, y un incremento en el tiempo de duracion.
laevifrons possess a vasoconstrictor
mechanism for high sensitivity mediated by Ach indicating the presence of two muscarinic receptors: one high of sensitivity and a second of lower sensitivity coupled to different mechanisms of activation.
Autonomic instability enhanced basal vasoconstrictor
tone and pressor response to applied cold stimulus could make these obese Subjects prone to hypertension and other cardiovascular disorders later in life.
By blocking angiotensin converting enzyme, ACE inhibitors significantly block the conversion of angiotensin I to angiotensin II, thus lowering blood pressure via reducing the production of the strong vasoconstrictor
