Abstract:
The purpose of this research study was to establish ziprasidone HCl NR 40 mg and trihexyphenidyl HCl SR 4mg in the form of bi-layer sustained release floating tablets. The tablets were prepared using sodium HPMC K4M / HPMC K15M as bio-adhesive polymers and sodium bicarbonate acting as a floating layer. Tablets were evaluated based on different parameters such as thickness, hardness, friability, weight variation, in vitro dissolution studies, content of active ingredient and IR studies. The physico-chemical properties of the finished product complied with the specifications. In vitro release from the formulation was studied as per the USP XXIII dissolution procedure. The formulations gave a normal release effect followed by sustained release for 12 h which indicates bimodal release of ziprasidone HCl from the matrix tablets. The data obtained was fitted to Peppas models. Analysis of n values of the Korsmeyer equation indicated that the drug release involved non-diffusional mechanisms. By the present study, it can be concluded that bi-layer tablets of ziprasidone HCl and trihexyphenidyl HCl will be a useful strategy for extending the metabolism and improving the bioavailability of Ziprasidone HCl and Trihexyphenidyl HCl.

Abstract:
Costello syndrome (CS), a rare syndrome with multisystemic involvement inherited as a dominant trait, is characterized by developmental delay, coarse facial appearance, cardiac defects including hypertrophic cardiomyopathy, skin abnormalities, brain complications, and a predisposition to certain malignancies. The musculoskeletal system is particularly affected in CS, with peculiar orthopedic anomalies that impact posture and gait. Dystonia has been recently documented to contribute to abnormal postures and musculoskeletal anomalies characterizing CS, suggesting the possible use of pharmacological treatments to treat these complications. We report the case of a child affected by CS displaying a particularly severe musculoskeletal involvement with dystonic posture especially in the arms and legs. The Movement Disorder-Childhood Rating Scale (MD-CRS) and a gait analysis were used to assess clinical patterns of hyperkinetic movement disorder and dystonia. The child was further treated with trihexyphenidyl for six months with a final dosage of 14 mg. MD-CRS and gait analysis assessments provided evidence for a significant improvement of posture and the related musculoskeletal problems with no side effects. Our preliminary study report provides first evidence that pharmacological anti-dystonia treatment significantly improves movement and posture disorders in patients with CS. Further studies enrolling larger cohorts of patients should be performed to validate these preliminary observations.

Abstract:
A new, simple, precise, rapid, selective and stability indicating reversed-phase high performance liquid chromatographic (HPLC) method has been developed and validated for simultaneous quantification of trihexyphenidyl hydrochloride, trifluoperazine hydrochloride and chlorpromazine hydrochloride from combined tablet formulation. The method is based on reverse-phase using C-18 (250×4.6) mm, 5 μm particle size column. The separation is achieved using isocratic elution by methanol and ammonium acetate buffer (1% w/v, pH 6.5) in the ratio of 85:15 v/v, pumped at flow rate 1.0 mL/min and UV detection at 215 nm. The column is maintained at 30 °C through out the analysis. This method gives baseline resolution. The total run time is 15 min. Stability indicating capability is established buy forced degradation experiment. The method is validated for specificity, accuracy, precision and linearity as per International conference of harmonisation (ICH). The method is accurate and linear for quantification of trihexyphenidyl hydrochloride, trifluoperazine hydrochloride and Chlorpromazine hydrochloride between 5 - 15 μg/mL, 12.5- 37.5 μg/mL and 62.5 - 187.5 μg/mL respectively.

Abstract:
Trihexyphenidyl (THP) is used to treat symptoms of Parkinson's disease or involuntary movements due to the side effects of certain psychiatric drugs. It can also decrease other side effects such as muscle stiffness/rigidity (extrapyramidal syndrome or EPS). EPS were an unavoidable consequence of effective antipsychotic therapy. EPS reduce beneficial effects of antipsychotic treatment on the negative, cognitive, and mood symptom domains, while increasing the risk of tardive dyskinesia and reducing compliance. The purpose of this research was to analyze the percentage use of THP and the pattern of THP usage on schizophrenia patient which treated at Sambang Lihum Hospital. This retrospective observational study was conducted at an inpatient Sambang Lihum Hospital. This research were conducted to 264 medical records of patients period January 2013 to December 2013 which receive antipsychotics medication. Data were analyzed by univariate analysis. The result showed 94.32% (n=264) received THP. This research has shown the pattern of THP usage in Sambang Lihum Hospital which was to give THP directly to patients without EPS examination is 96.79% (n=249) and there are 15.66% (n=249) patients evaluated after 14 days after THP administered.

Abstract:
Background: The demand of an efficient nanocarrier in drug delivery, graphene and its derivatives are emerging as a rising star due to its remarkable chemical and structural properties. Objective: Graphene oxide (GO) has high surface area and ability to load high amount of aromatic drugs. Hence, the objective of the research was to load Trihexyphenidyl hydrochloride (THP), antiparkinsonian drug on GO ultrasonically by π-π stacking interaction. Methods: GO was synthesized by the modified Hummer method. The conjugation of GOTHP was generated by using Design-Expert Software and release study of GO-THP nanohybrids was performed in the dissolution tester by using a dialysis membrane. Results: By varying an amount of GO and THP, the effect on loading efficiency and drug release was studied. THP showed sustained release behavior with release efficiency of 89% to 98% over 8 h. GO-THP complex was characterized by UV-vis spectrophotometer, FTIR, FESEM and XRD analysis. Conclusion: GO-THP complex showed better-sustained release of the drug and can be useful for the reduction dose frequency as well as adverse effect with better patient compliance.

Abstract:
Aim: Glioblastoma is a heterogeneous lethal disease, regulated by a stem-cell hierarchy and the neurotransmitter microenvironment. The identification of chemotherapies targeting individual cancer stem cells is a clinical need. Methodology: A robotic workstation was programmed to perform a drug concentration to cell-growth analysis on an in vitro model of glioblastoma stem cells (GSCs). Mode-of-action analysis of the selected top substance was performed with manual repetition assays and acquisition of further parameters. Results: We identified 22 therapeutic potential substances. Three suggested a repurpose potential of neurotransmitter signal-modulating agents to target GSCs, out of which the Parkinson's therapeutic trihexyphenidyl was most effective. Manual repetition assays and initial mode of action characterization revealed suppression of cell proliferation, cell cycle and survival. Conclusion: Anti-neurotransmitter signaling directed therapy has potential to target GSCs. We established a drug testing facility that is able to define a mid-scale chemo responsome of in vitro cancer models, possibly also suitable for other cell systems.
