  • Treatment of triple-negative breast cancer (TNBC) has been limited due to the lack of molecular targets. In this study, we evaluated the cytotoxicity of hydroxyzine, a histamine H1 receptor antagonist in human triple-negative breast cancer BT-20 and HCC-70 cells. Hydroxyzine inhibited the growth of cells in dose- and time-dependent manners. The annexin V/propidium iodide double staining assay showed that hydroxyzine induced apoptosis. The hydroxyzine-induced apoptosis was accompanied down-regulation of cyclins and CDKs, as well as the generation of reactive oxygen species (ROS) without cell cycle arrest. The effect of hydroxyzine on the induction of ROS and apoptosis on TNBC cells was prevented by pre-treatment with ROS scavengers, N-acetyl cysteine or Mito-TEMPO, a mitochondria-targeted antioxidant, indicating that an increase in the generation of ROS mediated the apoptosis induced by hydroxyzine. Western blot analysis showed that hydroxyzine-induced apoptosis was through down-regulation of the phosphorylation of JAK2 and STAT3 by hydroxyzine treatment. In addition, hydroxyzine induced the phosphorylation of JNK and p38 MAPK. Our results indicate that hydroxyzine induced apoptosis via mitochondrial superoxide generation and the suppression of JAK2/STAT3 signaling.

  • Hydroxyzine is one of the most popular oral sedatives used in pediatric dentistry. This study aimed to investigate the safety and possible side effects of sedation using hydroxyzine in pediatric dentistry. "Hydroxyzine," "Dental sedation," "Child," and "Safety" and their associated synonyms were searched using the Cochrane Library, Embase, PubMed, KISS, KMBASE, and KoreaMed databases. Academic information and portals of DBpia and RISS were also perused. Altogether, 340 papers were found, among which a total of 24 papers were selected according to the detailed criteria. Nine studies used hydroxyzine as monotherapy, and 10 studies compared its safety when hydroxyzine used as multitherapy. In addition, seven studies employed a drug regimen wherein hydroxyzine was one of the components. All these studies revealed that the adverse events specific to hydroxyzine usage were drowsiness and dryness of the mouth, and that there were respiratory complications due to a synergistic reaction of hydroxyzine. Although classified as a histamine blocker, hydroxyzine with its sedative, antiemetic, anticonvulsant, and anticholinergic properties is an oral sedative available without serious adverse events, If the proper dosage of the drug is used and its synergistic effects with other drugs are ascertained in the route of administration.

  • Orally administered chloral hydrate is often used, because of it's wide margin of safety and relatively few sideeffects. Hydroxyzine is an antihistamine with sedative and anti-emetic properties. It has been used in conjunction with chloral hydrate to reduce the incidence of nausea and vomiting. But, it's therapeutic drug concentration has not been established. The purpose of this study was to assess the sedative effect and physiologic parameter of hydroxyzine of different doses in sedating young pediatric dental patients. Fifty uncooperative children, mean age 33.2 months, who needed at least four separate restorative visits, requiring local anesthesia participated in this study. On every visit, one of the following 4 different sedative regimen was given (1) 70mg/kg CH (2) 70mg/kg CH and 1mg/kg HD (3) 70mg/kg CH and 2mg/kg HD (4) 70mg/kg CH and 3mg/kg HD. Physiologic parameter was recorded and behavior was videotaped and rated using Ohio State University Behavior Rating Scale by one investigator, blind to the dose. The analyzed sedative effect of combined oral administration of 70mg/kg chloral hydrate and 2mg/kg hydroxyzine was superior to the other regimens.

  • The purpose of this study was to compare the efficacy and complications of two oral sedative regimens, chloral hydrate (60mg/kg)/hydroxyzine(25mg) versus midazolam(1mg/kg)/meperidine(1mg/kg) for the sedation of pediatric dental patients. Fifteen patients(mean age 36.2months, range 24-47months), ASA Class I or II, who needed at least two restorative dental procedures were selected in this double-blind, randomized study. All subjects were randomly assigned to receive either chloral hydrate/hydroxyzine or midazolam/meperidine and 50% $N_2O/O_2$ was administered at each appointment. Behavior assessment(sleep, movement, crying, overall behavior) was made using Houpt Sedation Rating Scale and physiologic parameters(pulse rate, oxygen saturation) were monitored using pulse oximeter. The incidence of hypoxia($SpO_2$ 90% or less, at least 10s duration) and vomiting was recorded. Patients sedated with chloral hydrate/hydroxyzine showed significantly better overall behavior score than patients sedated with midazolam/meperidine. There was no clinically significant difference in the incidence of hypoxia and vomiting. It was concluded that oral administration of chloral hydrate/hydroxyzine is more effective than midazolam/meperidine for the sedation of pediatric dental patients.

  • The purpose of this study was to assess the sedative effect of three kinds of medication for management of the uncooperative 60 children aged from 16 months to 87 months required extensive treatment. The patients were given randomly a dose of 75mg/kg of chloral hydrate and hydroxyzine 25mg orally or 0.5mg/kg of midazolam orally or 0.3mg/kg of midazolam intranasally. All the children were restrained in a Pediwrap and were monitored with Pulse oximeter for assessing the safety of patients. According to rating scale, sleep, crying, movement, and overall behavior were checked for evaluation of the clinical sedative effect. The results were as follows: 1. In the evaluation of sleep, rating scale of chloral hydrate/hydroxyzine was superior to the other group(p<0.05). 2. In the evaluation of crying and movement at beginning of treatment, rating scale of chloral hydrate/hydroxyzine was superior to the other group(p<0.05), but during the treatment, rating scale of each group was not significantly different (p>0.05). 3. In the evaluation of overall behavior, 80% children of chloral hydrate/hydroxyzine were rated good or very good. With the oral and intranasal midazolam, 60% children were rated good or very good respectively. 4. There were no clinical signs of significant cyanosis and respiratory depression. Clinically, chloral hydrate/hydroxyzine was proved to be more effective sedation than any other sedative method. Oral and intranasal midazolam were also safe and effective sedation in young children undergoing pediatric dental procedures.
