Drug-induced blepharospasm may occur with antihistamines, dopaminomimetic,
sympathomimetic drugs or prolonged exposure to dopamine antagonists (7).
Sensitivity to the catecholamines is enhanced by TCAs, which may result in arrhythmias and hypertension when indirect- or direct-acting
sympathomimetic drugs are used.[1] Similarly, anesthetics known to increase endogenous circulating catecholamines such as ketamine-, pancuronium-, and epinephrine-containing solution should be avoided.[4] Vasopressin is a nonapeptide hormone synthesized in the magnocellular neurons of the paraventricular and supraoptic nuclei of the hypothalamus.[5] The vasoconstrictive effect of vasopressin is independent of catecholamine and angiotensin receptors.

Sympathomimetic drugs (partial agonists), such as Pindolol (11)
Intracavernosal treatment * Injection of
sympathomimetic drugs (phenylephrine) 4.
Hypertension may result from use of illicit drugs, oral contraceptives, herbal supplements, nonsteroidal anti-inflammatory medications, some psychiatric medications, steroids, or
sympathomimetic drugs like diet pills or decongestants (Vera & Neutze, 2010).
For instance,
sympathomimetic drugs can lead to rapid increase in blood pressure, arrhythmias, myocardial infarction and heart failure,particularly in elderly patients with coronary artery disease.
Catecholamines,
sympathomimetic drugs and adrenergic receptors antagonists.
Several classes of drugs including topical mydriatics anticolinergics antidepressants anticonvulsants antihistaminics sulphamate derivative adrenergics and
sympathomimetic drugs have the capacity to actuate an acute attack of angle closure.7
VENTRICULAR PREMATURE COMPLEXES [VPC]: VPC's are often the commonly seen arrhythmias during the peri-operative period and can be caused by cardiac and non-cardiac factors like electrolyte imbalances, hypoxia, hypercarbia, anesthetic agents, tobacco, caffeine, alcohol,
sympathomimetic drugs and antidepressant drugs.
Summary: TEHRAN (FNA)- Researchers at Payam-e-Noor University of Tehran in collaboration with experts from Tabriz University of Medical Sciences found a simple synthesis method for zinc oxide (and hydroxide) and their application in modified carbon paste electrodes for determination of
sympathomimetic drugs at micro-molar scales.
Administration of
sympathomimetic drugs is the most effective method for maintaining blood pressure and tissue perfusion during anesthesia in horses.
Sympathomimetic drugs, including cocaine and amphetamines, are commonly associated with intracranial hemorrhage, possibly due to transient hypertension or arteritis-like vascular change.
