Application

Quinine hemisulfate salt monohydrate has been used as a stimuli to evaluate its influence on sensory and cognitive factors.

Biochem/physiol Actions

Potassium channel blocker. Antimalarial, anticholinergic, antihypertensive, and hypoglycemic agent; alkaloid originally isolated from the Cinchona family of South American trees. Inhibits mitochondrial ATP-regulated potassium channel. Used to study the metabolism of biocrystalized heme, hemozoin, in malarial parasites and to study the toxicity of heme (FP)-complexes.
Quinine has analgesic property.

Quinine and quinidine are reported to potentiate the behavioural effects of serotonergic agents and monoamine uptake inhibitors. We have therefore investigated the presynaptic actions of quinine and quinidine on monoamine uptake and release in rat brain tissue in vitro. Quinidine

The pharmacokinetic interaction between quinidine and digoxin in patients is well-known, in general requiring a dose reduction of digoxin in patients concomitantly treated with quinidine. Quinine, the diastereomer of quinidine, has not been as extensively studied in this respect. In

The effect of quinine, a cinchona alkaloid, was studied on gastrointestinal transit in mice. Intraperitoneal (i.p.) administration of quinine inhibited the intestinal propulsion of a charcoal suspension at a dose of 100 mg/kg, comparing favorably with 5 mg/kg morphine. In

More women are being diagnosed with alcohol use disorder (AUD), are increasing the amount of alcohol they are drinking, and are partaking in risky drinking behaviors. Compulsive drinking which persists despite negative consequences is a hallmark of AUD. Preclinical aversion-resistant

Alcoholism, clinical and experimental research, 43(2), 243-249 (2018-11-16)
Alcohol use disorder is characterized by compulsive alcohol intake, or drinking despite negative consequences. Previous studies have shown that female rodents have a heightened vulnerability to drug use across different stages of the addictive cycle, but no previous studies have
