Cannabinoid hyperemesis syndrome (CHS) is an underrecognized diagnosis among adolescents. In the adult literature, it is characterized as nausea, vomiting, and abdominal pain in patients with chronic marijuana use. CHS is often refractory to the standard treatment of nausea and vomiting. Unconventional antiemetics, such as haloperidol, have been successful in alleviating symptoms; however, even 1 dose of haloperidol can lead to grave adverse effects, such as dystonia, extrapyramidal reactions, and neuroleptic malignant syndrome...

Flavonoids are natural compounds showing anti-hyperalgesic activity in models of pain. Diosmin is a compound poorly studied in the treatment of neuropathic pain. This study evaluates the anti-hyperalgesic actions of diosmin and possible mechanisms of action involved by using a neuropathic pain model in rats. Experimental neuropathic pain was induced by chronic constriction injury (CCI) in male Wistar rats, then aesthesiometric index and plantar tests were assessed to evaluate mechanical and thermal hyperalgesia, respectively, in order to explore the analgesic effects of acute and sub-chronic treatment with diosmin...

Functional recovery after a stroke is important for patients' quality of life. Not only medical care during the acute phase, but also rehabilitation during the chronic phase after a stroke is important. However, the mechanisms underlying functional recovery, particularly the chronic phase after stroke, are still not fully understood. Thus, further basic study on brain after focal stroke is necessary. In this study, we found that the concentration of dopamine (DA) increased during first week after a stroke in the hemisphere contralateral in the site of stroke by in vivo microdialysis...

BACKGROUND: Chlorpromazine is the only drug approved by the US Food and Drug Administration for the treatment of hiccups; however, many other pharmacologic treatments have been proposed for intractable and persistent hiccups. Currently, there is little evidence to support the use of one agent over another. OBJECTIVE: This review aims to identify literature concerning the use of pharmacologic treatments for intractable and persistent hiccups with the goal of evaluating therapies in terms of their level of evidence, mechanism of action, efficacy, dosing, onset of action, and adverse effects...

BACKGROUND: Acute agitation in the setting of alcohol intoxication is commonly encountered in the Emergency Department (ED). In this setting, expert consensus guidelines recommend haloperidol over second-generation antipsychotics due to their limited safety data in alcohol intoxication. OBJECTIVE: The primary objective was to compare vital sign changes prior to and after risperidone administration between ED patients presenting with alcohol intoxication [ETOH (+)] and without alcohol intoxication [ETOH (-)]...

Placebo effects have been reported in patients with chronic neuropathic pain. Expected pain levels and positive emotions are involved in the observed pain relief, but the underlying neurobiology is largely unknown. Patients with neuropathic pain are highly motivated for pain relief, and as motivational factors such as expectations of reward, as well as pain processing in itself, are related to the dopaminergic system, it can be speculated that dopamine release contributes to placebo effects in neuropathic pain...

The dopamine D2 receptor (D2R), like many G-protein coupled-receptors, signals through G-protein and β-arrestin-dependent pathways. Preferential activation of one of these pathways is termed functional selectivity or biased signaling and is a promising therapeutic strategy. Though biased signaling through D2Rs has been demonstrated, acquiring the mechanistic details of biased D2R/G-protein and D2R/β-arrestin signaling in vivo has been challenging due to the lack of techniques that specifically target these interactions in discrete cell populations...

Diet-induced obesity is a laboratory procedure in which nonhuman animals are chronically exposed to a high-fat, high-sugar diet (i.e. cafeteria diet), which results in weight gain, altered sensitivity to reward, and alterations in the dopamine D2 system. To date, few (if any) studies have examined age-related diet-induced obesity effects in a rat model or have used an impulsive choice task to characterize diet-induced behavioral alterations in reward processes. We exposed rats to a cafeteria-style diet for eight weeks starting at age 21 or 70 days...

The primary aim of this study was to identify pharmaceutically acceptable amorphous polymers for producing 3D printed tablets of a model drug, haloperidol, for rapid release by fused deposition modeling (FDM). Filaments for 3D printing were prepared by hot melt extrusion at 150°C with 10 and 20% w/w of haloperidol using Kollidon(®) VA64, Kollicoat(®) IR, Affinsiol(™)15 cP and HPMCAS either individually or as binary blends (Kollidon(®) VA64+Affinisol(™)15 cP, 1:1; Kollidon(®) VA64+HPMCAS, 1:1). Dissolution of crushed extrudates was studied at pH 2 and 6...

Chronic administration of antipsychotic drugs has been linked to structural brain changes observed in patients with schizophrenia. Recent MRI studies have shown rapid changes in regional brain volume following just a single dose of these drugs. However, it is not clear if these changes represent real volume changes or are artefacts ("apparent" volume changes) due to drug-induced physiological changes, such as increased cerebral blood flow (CBF). To address this, we examined the effects of a single, clinical dose of three commonly prescribed antipsychotics on quantitative measures of T1 and regional blood flow of the healthy human brain...

AIMS: Haloperidol is an antipsychotic agent and acts as dopamine D2 receptor (D2R) antagonist, as a prototypical ligand of sigma1 receptors (Sig1R) and it increases expression of type 1 IP3 receptors (IP3R1). However, precise mechanism of haloperidol action on cardiomyocytes through dopaminergic signaling was not described yet. This study investigated a role of dopamine receptors in haloperidol-induced increase in IP3R1 and Sig1R, and compared physiological effect of melperone and haloperidol on basic heart parameters in rats...

G protein-coupled receptors (GPCR) exhibit the ability to form receptor complexes that include molecularly different GPCR (i.e. GPCR heteromers), which endow them with singular functional and pharmacological characteristics. The relative expression of GPCR heteromers remains a matter of intense debate. Recent studies support that adenosine A2A receptors (A2A R) and dopamine D2 receptors (D2 R) predominantly form A2A R-D2 R heteromers in the striatum. The aim of the present study was evaluating the behavioral effects of pharmacological manipulation and genetic blockade of A2A R and D2 R within the frame of such a predominant striatal heteromeric population...

Dopamine is important for motor control and involved in the regulation of circadian rhythm. We previously found that dopamine-deficient (DD) mice became hyperactive in a novel environment 72 h after the last injection of L-3,4-dihydroxyphenylalanine (L-DOPA) when dopamine was almost completely depleted. DD mice did not initially exhibit hyperactivity in their home cages, but the animals exhibited hyperactivity several hours after the last L-DOPA injection. The regulation of motor activity in a novel environment and in home cages may be different...

BACKGROUND: The presentation of schizophrenia (SCH) symptoms differs between the sexes. Long-term treatment with antipsychotics is frequently associated with decreased bone mineral density, increased fracture risk and metabolic side effects. Perinatal phencyclidine (PCP) administration to rodents represents an animal model of SCH. The aim of this study was to assess the effects of chronic haloperidol and clozapine treatment on bone mass, body composition, corticosterone, IL-6 and TNF-α concentrations and metabolic parameters in male and female rats perinatally treated with PCP...

Many drugs commonly prescribed during pregnancy lack a fetal safety recommendation - called FDA 'category C' drugs. This study aims to classify these drugs into harmful and safe categories using knowledge gained from chemoinformatics (i.e., pharmacological similarity with drugs of known fetal effect) and empirical data (i.e., derived from Electronic Health Records). Our fetal loss cohort contains 14,922 affected and 33,043 unaffected pregnancies and our congenital anomalies cohort contains 5,658 affected and 31,240 unaffected infants...
