The primary application for phentolamine is for the control of hypertensive emergencies, most notably due to pheochromocytoma. [5]It also has usefulness in the treatment of cocaine-induced cardiovascular complications, where one would generally avoid β-blockers (e.g. metoprolol), as they can cause unopposed α-adrenergic mediated coronary vasoconstriction, worsening myocardial ischemia and ...
Crack cocaine: Heroin: Chocolate rock, dragon rock, eightball, moonrock, smoking gun, tar Crack cocaine: LSD: Cracid, outerlimits Cracid is a portmanteau of crack cocaine and acid [citation needed] Crack cocaine: Methamphetamine: Fire, twisters Crack cocaine: Nicotine: Coolie, crimmie, woolas A cigarette laced with crack [citation needed ...
The mechanisms of sympathomimetic drugs can be direct-acting (direct interaction between drug and receptor), such as α-adrenergic agonists, β-adrenergic agonists, and dopaminergic agonists; or indirect-acting (interaction not between drug and receptor), such as MAOIs, COMT inhibitors, release stimulants, and reuptake inhibitors that increase the levels of endogenous catecholamines.
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 ...
Cocaine is a relatively "balanced" inhibitor, although facilitation of dopaminergic neurotransmission is what has been linked to the reinforcing and addictive effects. In addition, cocaine has some serious limitations in terms of its cardiotoxicity [194] due to its local anesthetic activity. Thousands of cocaine users are admitted to emergency ...
Adrenergic antagonists are used to treat acute cardiovascular toxicity (e.g. in overdose) caused by sympathomimetics, for instance caused by amphetamine, methamphetamine, cocaine, ephedrine, and other drugs. [19]
diazepam, benzodiazepines, beta blockers, anti-hypertensives An adrenergic storm is a sudden and dramatic increase in serum levels of the catecholamines adrenaline and noradrenaline (also known as epinephrine and norepinephrine respectively), with a less significant increase in dopamine transmission.
This is the list of Schedule II controlled substances in the United States as defined by the Controlled Substances Act. [1] The following findings are required, by section 202 of that Act, for substances to be placed in this schedule:
