ABSTRACT
Objective To observe the clinical effect of Yi'naokang Capsules combined with Donepezil Hydrochloride Tablets in treating post-stroke cognitive impairment(PSCI).Methods 110 patients who met the diagnostic criteria of PSCI in the outpatient department were included.According to the random number table method,the patients were divided into trial group and control group,with 55 cases in each group.Patients in control group were treated with routine western medicine,including the treatment of Donepezil Hydrochloride Tablets and secondary prevention of stroke such as lowering blood pressure,lowering blood lipid,lowering blood glucose and anti-platelet aggregation.The trial group was treated with Yi'naokang Capsules on the basis of the treatment in control group,and both groups were treated for 6 months.Before and after 6 months of treatment,the cognitive function of patients was evaluated by the Montreal Cognitive Assessment(MoCA)scale.The activity of daily living(ADL)scale was used to evaluate the ability of daily living,and the severity of cerebral white matter lesions was evaluated by Fazekas scale,and the adverse reactions were also observed.Results After 6 months of treatment,the total score of the MoCA,the scores of visual space and executive function,attention,delayed recall and the ADL of the two groups were all improved(P＜0.05),and the improvement degree of the trial group was better than that of the control group(P＜0.05).The Fazekas score of the trial group after treatment was no significant difference when compared with that before treatment(P＞0.05),but it increased in the control group after treatment(P＜0.05),and the effect of delaying white matter lesion in the trial group was better than that in the control group(P＜0.05).Conclusion Yi'naokang Capsules combined with Donepezil Hydrochloride Tablets are superior to Donepezil alone in the treatment of PSCI,which can safely and effectively improve the cognitive function and daily living ability of patients,as well as prolong the progress of white matter lesions.
ABSTRACT
Objective:To explore the potential application value of photobiomodulation and drug combination therapy in the treatment of Alzheimer's disease (AD).Methods:Twenty-five APPswe/PS1dE9 double transgenic mice were randomly divided into model control group, donepezil hydrochloride (DH) group, DH+10 Hz group, DH+20 Hz group, and DH+40 Hz group ( n=5); and 5 C57BL/6J mice were selected as blank control group. Mice in the DH group, DH+10 Hz group, DH+20 Hz group, and DH+40 Hz group were given intragastric administration of DH (1.3 mg/[kg·d] for 4 weeks). The mice in the DH+10 Hz group, DH+20 Hz group, and DH+40 Hz group were irradiated with 1050 nm near-infrared light at 10 Hz, 20 Hz and 40 Hz frequencies for 6 min/d for 4 consecutive weeks. After all these treatments, Morris water maze was used to detect the behavioral cognitive ability of mice in each group; Congo red staining was used to detect the amyloid deposition in hippocampal CA1 area; and ELISA was used to detect the protein expression levels of amyloid protein (Aβ) 1-40 and Aβ 1-42 in the hippocampus. Results:(1) As compared with that in the model control group, the escape latency of mice in the DH+40 Hz group was significantly shortened since the 4 th d of navigation test, and that in the DH group was significantly shortened since the 5 th d of navigation test ( P<0.05); that in the DH+40 Hz group was obviously shortened as compared with that in the DH group without significant difference ( P>0.05). As compared with the those in the model control group, the times of crossing the primary platform of mice in the DH group and DH+40 Hz group were singifcantly increased ( P<0.05), and those in the DH+40 Hz group were similar to those in the DH group. (2) DH+40 Hz group showed scattered brick-red dotted patches, the staining depth and distribution range were obviously smaller than those in the model control group, and the nuclear structure arrangement was more orderly than that in the model control group; the staining depth and number of brick red patches in the DH+40 Hz group were smaller than those in the DH group. (3) The concentrations of Aβ 1-40 and Aβ 1-42 in the hippocampal tissue homogenate of DH+40 Hz group were significantly decreased as compared with those in the model control group ( P<0.05). As compared with those in the DH group, the concentrations of Aβ 1-40 and Aβ 1-42 in hippocampal tissue homogenate of DH+40 Hz group were decreased without significant difference ( P>0.05). Conclusion:The combined treatment strategy of 40 Hz 1050 nm near-infrared light and DH may have the potential to improve the behavioral cognition of AD mice and moderately reduce the deposition of Aβ in the brain tissues.
ABSTRACT
Abstract: Simple, specific, accurate and cost economic UV spectrophotometric methods weredeveloped and validated for determination of Donepezil Hydrochloride. Instead of usingorganic solvents, mixture of Acetonitrile and water was used during method development andvalidation. Donepezil hydrochloride standard solution was scanned in the UV range (400-200nm) in a 1cm quartz cell in a double beam UV spectrophotometer. The standard solution ofDonepezil Hydrochloride showed maximum absorption at wavelength 231 nm. The methodobeys Beer’s law in the concentration range from 4-20µg/ml. The correlation coefficient wasfound to be 0.9983and regression of the curve was found Y=0.0376x+0.0185 with excellentrecovery 99.66-100.83%. Limit of detection and limit of quantification were found to be0.197µg/ml and 0.6µg/ml respectively. The ruggedness and robustness were performed. Themethod was validated for several parameters like accuracy, precision as per ICH guidelines.Statistical analysis proved that the methods are repeatable and specific for determination ofthe drug. These methods can be adopted in the routine assay analysis of DonepezilHydrochloride in API and pharmaceutical dosage form.

ABSTRACT
OBJECTIVE: The pharmacological effects of generic (GE) donepezil are the same as Aricept, its brand-name counterpart. However, little is known as to whether these two drugs provide the same quality of life (QOL). The study subjects were patients with Alzheimer's disease who were taking donepezil hydrochloride tablets, and were selected by visiting either the local pharmacies or the patients' homes. We chose the brand-name drug Aricept and its GE form donepezil to investigate, from a long-term caregiver's perspective, the influence of both drugs on the patients' QOL. METHODS: An EuroQol-5 Dimension (EQ-5D) was used to assess the QOL of patients with Alzheimer's disease, before and after various Aricept and/or donepezil regimens. Patients were divided into four groups: first time users of Aricept (n=43), first time users of GE donepezil (n=45), users refilling previous prescriptions of Aricept (n=51), and users switching from Aricept to GE donepezil (n=51). RESULTS: The average change in the EQ-5D utility indices rose significantly in the patients starting a new regimen of Aricept and its GE drug. The patients continuing an existing regimen of Aricept showed no significant differences, even after Aricept was switched to a GE drug. CONCLUSION: The QOL of patients starting a new regimen of Aricept and its GE drug improved. The QOL was maintained upon switching to the GE drug form.

ABSTRACT
The main aim of the present research was to develop a fast dissolving oral polymeric film with good mechanical properties, faster disintegration and dissolution when placed on tongue. Donepezil hydrochloride (DPH) is prescribed in the treatment of mild to moderate Alzheimer’s disease (AD). The polymers selected for preparing films were sodium alginate (SA), poly vinyl alcohol (PVA) and guar gum (GG). Three batches of films were prepared by solvent casting method with sodium alginate, sodium alginate & PVA and with the combination of sodium alginate & guar gum. From these three batches, three optimized film formulations S3, SP7 and SG8 were selected based on disintegration time. To these three selected film formulations, superdisintegrants sodium starch glycolate (SSG), cross carmellose sodium (CCS) and cross povidone (CP) were added at a concentration of 4% w/w of polymer to improve the disintegration time. The films prepared with or without superdisintegrants were compared for fast releasing properties. Based on DT and in vitro dissolution data, S3CP was selected as the best formulation among the all formulations.

ABSTRACT
OBJECTIVES: Recent studies in autistic brain samples have shown diminished acetylcholine and nicotinic receptor activity. We hypothesized that acetylcholinergic enhancement may pharmacologically improve some autistic characteristics. Donepezil hydrochloride, a cholinesterase inhibitor, was studied in few studies which showed improvement in the expressive and receptive speech of autistic children. We therefore undertook an open label trial to evaluate this effect on speech function in Korean autistic children. METHODS: Twenty-one patients (18 males, 3 females, average age 77.9+/-23.7 months), with a diagnosis of autism spectrum disorder enrolled in a 12-week open label trial of donepezil hydrochloride. Changes were evaluated by PLS (Preschool language scale). Testing was administered at baseline and at 12-week follow-up. RESULTS: Test administered at baseline and at 12-week follow-up showed gains in both expressive and receptive speech functions. CONCLUSION: Donepezil hydrochloride, a cholinesterase inhibitor, appears to improve expressive and receptive speech functions of autistic children.
