Pharmaceutics 2022; 14:2407. [PMID: 36365225 PMCID: PMC9695279 DOI: 10.3390/pharmaceutics14112407] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 11/03/2022] [Accepted: 11/05/2022] [Indexed: 10/15/2023] Open
Abstract
This study demonstrated the implementation of a liquisolid technique to formulate directly compressible orally disintegrating tablets (ODTs). Cannabidiol (CBD), a hydrophobic cannabinoid, was prepared as a liquisolid powder using microcrystalline cellulose-colloidal silicon dioxide as a carrier-coating material. Different liquid vehicles differing in their volatility, hydrophilicity, and viscosity were investigated. Each of the CBD-ODTs comprised CBD liquisolid powder (10 mg CBD), superdisintegrant, flavors, lubricant, and filler. The physical mixture (PM) ODT was prepared as a control. Ethanol-based ODTs (CBD-EtOH-ODTs) had comparable tablet properties and stability to CBD-PM-ODTs. ODTs with nonvolatile-vehicle-based liquisolid powder had lower friability but longer disintegration times as compared with CBD-PM-ODTs and CBD-EtOH-ODTs. Compression pressure influenced the thickness, hardness, friability, and disintegration of the ODTs. With a suitable compression pressure to yield 31-N-hardness-ODTs and superdisintegrant (4-8%), CBD-ODTs passed the friability test and promptly disintegrated (≤25 s). Times to dissolve 50% of CBD-PM-ODTs, CBD-EtOH-ODTs, and nonvolatile-vehicle-based CBD-ODTs were 10.1 ± 0.7, 3.8 ± 0.2, and 4.2 ± 0.4-5.0 ± 0.1 min, respectively. CBD-EtOH-ODTs exhibited the highest dissolution efficiency of 93.5 ± 2.6%. Long-term and accelerated storage indicated excellent stability in terms of tablet properties and dissolution. Nonvolatile-vehicle-based CBD-ODTs exhibited a higher percentage of remaining CBD. This study provides useful basic information for the development of ODT formulations using a liquisolid technique application.

Abstract
Obtaining orodispersible tablets (ODT) containing substances from the second Biopharmaceutical Class has raised concerns as the dissolution test is challenging. This study aimed to select suitable excipients for developing orodispersible tablets containing cannabidiol (CBD) by direct compression method. No similar studies were found in the literature. Excipients from different classes were characterized using the SeDeM-ODT tool: fillers – lactose (LCT) and microcrystalline cellulose (CelMC), sweeteners – sorbitol (SRB) and mannitol (MNT), disintegrants – sodium starch glycolate (SSG), sodium croscarmellose (CCS), soy polysaccharides (Emcosoy® – EMCS) and two co-processed excipients (Prosolv®-ODT G2 – PODTG2 and Prosolv® EasyTab sp – PETsp). Drug compatibility with excipients in binary mixtures (1:1) was verified by Differential Scanning Calorimetry (DSC) and Fourier Transform-Infrared (FTIR) spectroscopy. Using the SeDeM-ODT expert system, the fillers and the co-processed excipients showed good properties regarding compressibility and disintegration behavior. Also, the DSC and FTIR results showed that small or no interactions between the CBD and the excipients took place.

Mapping modifiable determinants of medication adherence in bipolar disorder (BD) to the theoretical domains framework (TDF): a systematic review. Psychol Med 2021; 51:1082-1098. [PMID: 34006337 PMCID: PMC8188530 DOI: 10.1017/s0033291721001446] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 03/25/2021] [Accepted: 04/01/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND Around 40% of people with bipolar disorder (BD) are non-adherent to medication leading to relapse, hospitalisation and increased suicide risk. Limited progress in addressing non-adherence may be partly attributable to insufficient understanding of the modifiable determinants of adherence that require targeting in interventions. We synthesised the modifiable determinants of adherence in BD and map them to the theoretical domains framework (TDF). METHOD We searched CINAHL, Cochrane Library, Embase, LILACS, Medline, PsychINFO and PubMed until February 2020. We included studies reporting modifiable determinants of adherence in BD. Two reviewers independently screened studies, assessed quality, extracted modifiable determinants and mapped them to TDF. RESULTS We included 57 studies involving 32 894 participants. Determinants reported by patients spanned 11 of the 14 TDF domains compared to six domains represented by clinician/researcher. The TDF domains most commonly represented (% and example) in studies were: 'Environmental context and resources' (63%, e.g. experiencing side effects), 'Beliefs about consequences' (63%, e.g. beliefs about medication effects), 'Knowledge' (40%, e.g. knowledge about disorder), 'Social influences' (33%, e.g. support from family/clinicians), 'Memory, attention and decision processes' (33%, e.g. forgetfulness), 'Emotion' (21%, e.g. fear of addiction) and 'Intentions' (21%, e.g. wanting alternative treatment). 'Intentions', 'Memory, attention and decision processes' and 'Emotion' domains were only reported by patients but not clinicians. CONCLUSIONS Clinicians may be underappreciating the full range of modifiable determinants of adherence and thus not providing adherence support reflective of patients' needs. Reporting of modifiable determinants in behavioural terms facilitates developing theory-based interventions to address non-adherence in BD.

Abstract
Background Postoperative cognitive dysfunction (POCD) is associated with poor quality of life and difficulty working. Its impact may be greater in middle-aged patients than in elderly patients. Neuroinflammation is reported to be a main cause of POCD. Olanzapine has been reported to improve learning and memory functions. We therefore investigated olanzapine's effectiveness and mechanisms in an adult rat POCD model. Methods Six-month-old rats underwent laparotomy and lipopolysaccharide (LPS group) or LPS + olanzapine (OLA group) intraperitoneal injection or anesthesia alone (CON group) 1 week after a Barnes maze training session. A Barnes maze test trial was then conducted the day after surgery or anesthesia. The microglial activity in the hippocampus and cytokine levels were measured by Iba1 staining and enzyme-linked immunosorbent assay, respectively. Results The OLA group had significantly higher success rates of Barnes maze trial than the LPS group. The success rate in time of the OLA group was inferior to that of the CON group. On the other hand, the success rate in distance of the OLA group was similar to that of the CON group. Iba1 staining areas in the LPS and OLA groups were larger than that in the CON group; however, the staining area in the OLA group was smaller than that of the LPS group. Plasma interleukin-1β concentration in the LPS and OLA groups was significantly higher than that in the CON group; however, there was no significant difference between the LPS and OLA groups. Conclusion Olanzapine attenuated both spatial cognitive dysfunction and microglial activity of the hippocampus, which were induced by surgery and LPS injection. These effects were unrelated to inflammatory cytokine concentrations in plasma and hippocampus.

Abstract
The objective of the current study was to develop ziprasidone hydrochloride monohydrate (ZHM) nanocrystal-based orally dispersible tablet (ODT) formulations. Design of experiment approach was used to develop ODTs. The tablets were compressed using direct compression method and characterized with quality control tests. In vitro dissolution studies and Caco-2 cell permeability tests were executed. The hardness and friability values of nanocrystal-based ODTs were found 31.2 N and 1.05%, respectively. The disintegration time was below 10 s. Dissolution profile in pH 7.4 phosphate buffer showed that nanocrystal-based ODTs and commercial product were dissolved in 120 min 58.98% and 16%, respectively. In pH 7.4 phosphate buffer with SLS, sample groups dissolved above 85% at the end of the study. Permeability value and cumulative ZHM amount on the cells were improved with nanocrystals. In conclusion, the novel formulation of ZHM nanocrystal-based ODTs was successfully developed for alternative dosage form.

Abstract
Fixed-dose combination (FDC) medicines containing two or more active pharmaceutical ingredients (APIs) in a single dosage form have been reported to improve patient adherence to a greater extent than single dosages of individual components (ICs). Orally disintegrating tablets (ODTs) are easier to swallow than conventional tablets. The aim of this study was to elucidate the clinical pharmaceutical characteristics of taking a FDC-ODT and two IC-ODTs. We prepared three ODTs containing mitiglinide, voglibose, and mitiglinide/voglibose and three corresponding placebo ODTs and performed 2 independent clinical trials with 13 healthy subjects (mean age, 23.4 ± 1.6 years). One trial evaluated the ease of taking tablets and the amount of water required for taking the tablets; placebo ODTs were used in order to avoid administering APIs. The other trial evaluated the bitterness, sweetness and overall palatability of ODTs containing APIs during disintegration and after spitting out. Ease and taste were evaluated using both a visual analog scale (VAS) and a verbal rating scale (VRS). The results of the VAS and VRS evaluation indicated that FDC-ODT could ease tablet intake unlike IC-ODTs. In addition, FDC-ODT reduced the amount of water required for tablet intake in contrast to IC-ODTs. Taste evaluation results did not reveal any difference between FDC-ODT and IC-ODTs, except for the sweetness score after spitting out. In conclusion, FDC-ODT is easy to take and can help improve patient adherence.

Abstract
OBJECTIVES This study aimed to analyze (1) the cost-effectiveness of olanzapine orally disintegrating tablet (ODT) compared to olanzapine standard oral tablet (SOT) and (2) the cost-effectiveness of olanzapine-SOT compared to aripiprazole-SOT for patients with schizophrenia in China. METHODS A microsimulation model was adapted from a healthcare payers' perspective. The model ran over a 1-year time horizon, using quarterly cycles. The costs of adverse events were acquired through a clinical expert panel. The average bidding prices in China of olanzapine-ODT, olanzapine-SOT, aripiprazole-SOT, and other switch alternatives were used. Inpatient and outpatient medical costs were sourced from the Urban Employee Basic Medical Insurance database in Tianjin. Additionally, adherence, efficacy, safety, and utility data were taken from the literature. Uncertainty of parameters were assessed through one-way and probabilistic sensitivity analyses. RESULTS The total annual costs per patient in aripiprazole-SOT arm, olanzapine-SOT arm, and olanzapine-ODT arm are USD 2,296.05, USD 1,940.05, and USD 2,292.81, respectively. The average number of relapses per patient in 1 year in the aripiprazole-SOT arm, olanzapine-SOT arm, and olanzapine-ODT arm, are 0.734, 0.325, and 0.198, respectively. The quality-adjusted life years (QALYs) gained per patient in 1 year in the aripiprazole-SOT arm, olanzapine-SOT arm, and olanzapine-ODT arm are 0.714, 0.737, and 0.758, respectively. Consequently, (1) the incremental cost-effectiveness ratios (ICERs) of administrating olanzapine-ODT over olanzapine-SOT are USD 2,791.96 per relapse avoided and USD 16,798.39 per QALY gained; and (2) the ICERs of using olanzapine-SOT over aripiprazole-SOT are USD -870.39 per relapse avoided and USD -15,477.93 per QALY gained. All ICERs are under the willingness-to-pay threshold in China of USD 25,772.67. The sensitivity analyses confirmed the robustness of the results. CONCLUSION As the first-line treatment for schizophrenia in China, olanzapine-ODT is cost-effective compared to olanzapine-SOT and olanzapine-SOT is cost-effective compared to aripiprazole-SOT.
