To examine theeffects on the brain of 2-month treatment withamethylphenidate extended-release formulation (OROS-MPH) using [Tc-] TRODAT-1SPECT in a sample of treatment-naïve adolescents with Attention Deficit/Hyperactivity Disorder (ADHD). In addition, to assess whether risk alleles (homozygosity for 10-repeat allele at the DAT1 gene were associated with alterations in striatal DAT availability.
Attention deficit hyperactivity disorder (ADHD) is a life-long neurodevelopmental disorder and treatment depends on pharmacotherapy because of its biological origin. Stimulant drugs are the most commonly used treatment for ADHD and they have various side effects. Herein, we report a case who bit off the tip of her tongue with Osmotic Release Oral System methylphenidate (OROS MPH) 36 mg/day, bit the tip of her lower lip with immediate release (IR) MPH 10 mg/day and lateral part of her tongue with IR MPH 20 m...
Carboxylesterase 1 (CES1) metabolizes methylphenidate and other drugs. CES1 gene variation only partially explains pharmacokinetic (PK) variability. Biomarkers predicting the PKs of drugs metabolized by CES1 are needed. We identified lipids in plasma from 44 healthy subjects that correlated with CES1 activity as determined by PK parameters of methylphenidate including a ceramide (q value = 0.001) and a phosphatidylcholine (q value = 0.005). Carriers of the CES1 143E allele had decreased methylphenid...

Effect sizes were weighted using a random-effects model. Scores on n...
Much remains unclear about the benefits and harms of methylphenidate for children and adolescents with attention-deficit/hyperactivity disorder (ADHD). Between 2012 and 2018, we conducted two Cochrane systematic reviews on methylphenidate for ADHD. This article explores the main findings in relation to evidence-based practice and our current understanding of ADHD.
A methylphenidate (MPH) extended-release orally disintegrating tablet (MPH XR-ODT) formulation was recently approved for attention-deficit/hyperactivity disorder treatment in children 6 to 17 years of age. This analysis sought to develop a population pharmacokinetic (PK)/pharmacodynamic (PD) model to describe MPH XR-ODT PD-response data in a classroom study and use the model to simulate PD responses for a range of body weights and doses.
Previous research has detected an increased risk of stress fractures among subjects who reported previous use of methylphenidate. Conversely, stimulant medication use has been associated with traumatic fracture risk reduction, possibly because of the improved control of the underlying symptoms of attention deficit hyperactivity disorder (ADHD). The goal of this study was to investigate the effect of previous methylphenidate use on the incidence of traumatic and stress fractures among combat soldiers with pr...
Stimulant drugs such as nicotine (NIC) and methylphenidate (MPH) are hypothesized to increase the reinforcing value of sensory stimuli, thus increasing the effectiveness of such reinforcers as alternatives to sucrose reinforcers.
This study examines the preparation of sustained-release lidocaine polyelectrolyte complex using reactive melt extrusion. Eudragit L100-55 was selected as the ionic polymer. The influence of drug forms (freebase vs. hydrochloride salt) on lidocaine-Eudragit L100-55 interactions, physical stability, and dissolution properties of extrudates was investigated. It was confirmed by DSC, FT-IR and Raman spectroscopy that polyelectrolyte could only form via the acid-base reaction between Eudragit L100-55 and lidoca...
Methylphenidate (MP) use is highly prevalent among children and young adults. Previous basic and epidemiological research demonstrated an adverse effect of MP on bone mass. Studies in military recruits have shown that history of MP use before conscription was a risk factor for stress fractures (SF) during the service.
A randomized, double-blind, non-inferiority study of hydromorphone hydrochloride immediate-release tablets versus oxycodone hydrochloride immediate-release powder for cancer pain: efficacy and safety in Japanese cancer patients.
Hydromorphone is a standard opioid analgesic for cancer pain that, prior to this study, was not approved in Japan, where options for opioid switching are limited. We aimed to investigate the efficacy and safety of hydromorphone (DS-7113b) immediate-release tablets in opioid-naïve cancer patients with moderate to severe cancer pain.
The effectiveness of psychostimulants, primarily methylphenidate (MPH), in the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in the general population of typically growing children and adolescents is well established through many Randomised Controlled Trials (RCTs).
The inhibitory effects of ammonium chloride (NHCl) and chlorpromazine hydrochloride on betanodavirus were evaluated on Sahul Indian sea bass kidney (SISK) cell line. The cytotoxicity of different concentrations of NHCl (0.1 mM, 1 mM, 10 mM, 100 mM and 500 mM) and chlorpromazine hydrochloride (1 μM, 10 μM, 100 μM, 200 μM and 500 μM) were assessed in SISK cells using different cytotoxic assays. Among the selected concentrations, 0.1 mM, 1 mM and 10 mM of NHCl and chlorpromazine ...
The aim of this study was to evaluate the influence of Denaverine hydrochloride (DNH) in heifers on calf vitality.
This study aimed to compare the effectiveness of parental training (PT), methylphenidate treatment (MPH), and the combination of PT and MPH treatment (PT/MPH) on school achievements in children with attention-deficit hyperactivity disorder (ADHD). Twenty eight ADHD patients (age: 10.1±1.11 years) were divided into three groups: (a) PT (N=10), (b) PT/MPH (N=8), and (c) MPH alone (N=10). Their grades in academics and conduct, from their school reports before and after treatment (6 months), were coded as achi...
The objective was to evaluate the action of D. flagrans pellets in association with Levamisole Hydrochloride 5% for controlling sheep gastrointestinal nematodes in the northeastern Brazil. Three groups of six sheep each were formed: group 1 received 3 g of the pellets (0.6 g of D. flagrans mycelium) for each 10 kg b.w., twice a week for six months, and deworming with Levamisole Hydrochloride 5% when EPG ≥ 1500; group 2 received a dosage of Levamisole Hydrochloride 5% when EPG ≥ 1500; and group 3 receive...
Development and validation of a novel, sensitive, specific and rapid dried blood spots (DBS)-LC-MS/MS method for methylphenidate (MPH), an attention-deficit hyperactivity disorder drug. Methodology & results: Protein precipitation with acetonitrile was used to extract MPH from the DBS cards.

Two structural isomers of cefotiam in cefotiam hydrochloride for injection were observed, and the structures of the isomers were determined by mass spectrometry and various 1D and 2D NMR techniques. The thermo-isomerization mechanism of cefotiam was also discussed. Thermo-isomerization occurred not only in cefotiam but also in cephalosporins containing a 1-alkyl-1H-tetrazole-5-thiol side chain at C-3. Furthermore, the toxic effects of the two impurities of cefotiam hydrochloride were predicted and it is tho...
We aimed to investigate the effectiveness and safety of methylphenidate (MPH), and especially its influence on seizures, in subjects with attention-deficit/hyperactivity disorder (ADHD) and epilepsy through a retrospective chart review of subjects treated with MPH in a clinical setting. We also evaluated factors that could affect seizure aggravation during MPH treatment.
Bigels with antifungal substances, ciclopirox olamine and terbinafine hydrochloride, were made of hydrogel (poloxamer 407 gel) and oleogel (polyethylene and liquid paraffin mixture). Prepared bigels were found physically stable at room temperature for six months and at least four months at 40 °C. Released amount of drug decreased when oleogel concentration in the formulation increased. Release test results depended on the insertion place of active substances. The amount of released substance was highest wh...
Retention in addiction treatment is associated with reduced mortality for individuals with opioid use disorder (OUD). Although clinical trials support use of OUD medications among youths (adolescents and young adults), data on timely receipt of buprenorphine hydrochloride, naltrexone hydrochloride, and methadone hydrochloride and its association with retention in care in real-world treatment settings are lacking.
To characterize the benefits and optimal dose of long-acting methylphenidate for management of long-term attention problems after childhood traumatic brain injury (TBI).
Treatment-resistant schizophrenia patients frequently need to be managed with clozapine. However, noncompliance is in-part due to complaints of sedation, fatigue, and low energy. There is little literature reporting on the effectiveness and safety of using stimulants to treat clozapine-induced sedation. We report three cases of treatment-resistant schizophrenia where methylphenidate was used to address these common side-effects.
One drawback of traditional forms of medical ocular dosage is drug dilution by tear; moreover, drugs are rapidly drained away from pre-corneal cavity by tear flow and lacrimo-nasal drainage. Prolonging contact time with different strategies and mucoadhesive vehicles will help to continuously deliver drugs to the eyes. For this study, we prepared and evaluated the effects of a nanostructure lipid carrier (NLC) on propranolol hydrochloride as a hydrophilic drug model for rabbit corneal permeation. Propranolol...
