Prediction of inter-individual variability on the pharmacokinetics of CYP1A2 substrates in non-smoking healthy volunteers.
Authors: Haraya K, Kato M, Chiba K, Sugiyama Y Abstract The activity of CYP1A2, a major drug-metabolizing enzyme, is known to be affected by various environmental factors. Our study aimed to predict inter-individual variability of AUC/Dose of CYP1A2 substrates in non-smoking healthy volunteers using the Monte Carlo simulation. Inter-individual variability in hepatic intrinsic clearance of CYP1A2 substrates (CLint,h,1A2) was estimated using dispersion model based on the inter-individual variability (N = 96) of the AUC of caffeine, a major CYP1A2 substrate. The estimated coefficient of variation (CV) of CLint,h,1A2...

Alpha2-adrenergic agonists for the management of opioid withdrawal.
CONCLUSIONS: Clonidine and lofexidine are more effective than placebo for the management of withdrawal from heroin or methadone. We detected no significant difference in efficacy between treatment regimens based on clonidine or lofexidine and those based on reducing doses of methadone over a period of around 10 days, but methadone was associated with fewer adverse effects than clonidine, and lofexidine has a better safety profile than clonidine.

Haloperidol as an Abortive and Preventative Agent in Status Dystonicus (P2.352)
We present two cases with histories of severe spasms, necessitating intrathecal baclofen pump placement, who both required intubation for status dystonicus. It was not until use of haloperidol as a preventative and abortive agent, that there was significantly decreased spasm frequency and severity in these patients. Cases: Patient 1 is a 40-year-old man with cerebral palsy and spasms controlled with a baclofen pump who was admitted for increasing spasms. Treatment with trihexyphenidyl, increasing amounts of baclofen (oral and intrathecal) and onabotulinumtoxinA injections lessened spasm frequency but did not eliminate them...

Drug safety of macrolide and quinolone antibiotics in a tertiary care hospital: administration of interacting co-medication and QT prolongation
Conclusion In the studied real-life setting, we found a considerable number of MQAB users with additional risk factors for TdP but no ECG monitoring. However, adverse drug reactions were rarely found, and costs vs. benefits of ECG monitoring have to be weighted. In contrast, avoidable risk factors and selected contraindicated pharmacokinetic interactions are clear targets for implementation as automated alerts in electronic prescribing systems.

Evaluation of tizanidine as a marker of canine CYP1A2 activity
The dog CYP1A2 enzyme is likely an important contributor to the metabolism of veterinary drugs. Dog CYP1A2 is expressed in liver, plus it is inducible and polymorphic, creating the potential for intersubject differences in pharmacokinetics. Hence, the ability to probe dog CYP1A2 activity and inhibition is relevant toward veterinary drug development and drug–drug interaction assessment. Previous studies have relied on human probes with questionable specificity for CYP1A2, so it was hypothesized that recombinant CYP1A2 could be used to find a specific CYP1A2 substrate. Intrinsic clearance experiments demonstrated that tiza...

Interventions to Reduce Spasticity and Improve Function in People With Chronic Incomplete Spinal Cord Injury: Distinctions Revealed by Different Analytical Methods
Conclusions. Improvements in function were achieved in a limited number of people with SCI. Using the MID and GMM techniques, differences in responses to interventions between high-and low-functioning participants could be identified. These techniques may, therefore, have potential to be used for characterizing therapeutic effects resulting from different interventions. (Source: Neurorehabilitation and Neural Repair)

Impact of Intravenous Acetaminophen on Reducing Opioid Use After Hysterectomy
ConclusionThe multimodal approach to perioperative analgesic management, which includes concurrent administration of intravenous acetaminophen and opioids, is effective in reducing the total average amount of opioids administered on postoperative days 1–2 and perioperatively. Limitations of this study include its short duration, retrospective design, and single‐site setting. These results may not be generalized to patients undergoing other types of obstetric‐gynecologic surgeries. (Source: Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy)

Cranberry juice ingestion and clinical drug-drug interaction potentials; review of case studies and perspectives.
Authors: Srinivas NR Abstract Cranberry juice is a popular beverage with many health benefits. It has anthocyanins to supplement dietary needs. Based on in vitro evidence cranberry juice is an inhibitor of CYP enzymes and at higher amounts as potent as ketoconazole (CYP3A) and fluconazole (CYP2C9). There is, however, a discrepancy between in vitro and in vivo observations with respect to a number of substrates (cyclosporine, warfarin, flurbiprofen, tizanidine, diclofenac, amoxicillin, ceflacor); with the exception of a single report on midazolam, where there was a moderate increase in the AUC of midazolam in subjec...

Central noradrenergic mechanisms and the acute stress response during painful stimulation
Events that threaten tissue integrity including noxious stimulation activate central noradrenergic circuits, particularly locus coeruleus and its projections. Recent advances in theory hold that an adaptive, defensive shift in brain activity takes place in response to threat. In principle, this shift may accentuate the autonomic and central biomarkers of the perception of painful events and the experience of pain itself. We have examined the effects of an alpha-2 agonist on pupil dilation responses, skin conductance responses, near field somatosensory evoked potentials and pain reports in normal volunteers undergoing repea...

Chronic Daily Headache: Diagnosis and Management.
Abstract Chronic daily headache is defined as the presence of a headache on 15 days or more per month for at least three months. The most common types of chronic daily headache are chronic migraines and chronic tension-type headaches. If a red flag for a secondary cause of headache is present, magnetic resonance imaging of the head should be performed. All patients should be asked about medication overuse, which can increase the frequency of headaches. Patients who overuse medications for abortive therapy for headache should be encouraged to stop the medications entirely and consider prophylactic treatment. Severa...

Non-antiepileptic drugs for trigeminal neuralgia.
CONCLUSIONS: There is low-quality evidence that the effect of tizanidine is not significantly different than that of carbamazepine in treating trigeminal neuralgia. Pimozide is more effective than carbamazepine, although the evidence is of low quality and the data did not allow comparison of adverse event rates. There is also low-quality evidence that 0.5% proparacaine hydrochloride eye drops have no benefit over placebo. Limitations in the data for tocainide prevent any conclusions being drawn. There is insufficient evidence from randomised controlled trials to show significant benefit from non-antiepileptic drugs in trig...
