Objective
: The present study aimed to validate a questionnaire and measure the previous knowledge, attitude, and practice (KAP) of the general population and healthcare professionals regarding the debilitating disorder of dementia.
Design
: A questionnaire including 27 items was compiled by the authors and was circulated via the online platform.
Setting
:A questionnaire-based survey was conducted using the online modality.
Participants
: A convenience sampling method was used to recruit participants aged 18 and above from all walks of life.
Measurements
: Test-retest reliability, item analysis, and Cronbach’s alpha were calculated for the compiled questionnaire. The responses of the participants were assessed using descriptive statistics and the chi-square test.
Results
: A total of 503 responses were collected. The internal consistency (Cronbach's alpha=0.70) was acceptable and the test-retest reliability (0.823) was good. Eighty-one percent (408/503) of participants had heard the word dementia. Seven percent (27/408) of the participants who had heard the word dementia did not have any knowledge about the symptoms of dementia. Thirty-three percent (136/408) of participants believed that dementia could not be prevented. Almost half, i.e., 46% (187/408) of participants, considered dementia as a normal part of aging.
Conclusions
: The present study provides a fully validated questionnaire, which could prove helpful in research as it permits generating high-quality data and reducing measurement error. Knowledge of dementia among the general participants seems to be moderate and prompts towards the development of advocacy programs.
The objective of the present research was to develop a Bilayer tablet of guaifenesin (GBT) using superdisintegrant MCC and sodium starch glycolate for the fast release layer and metalose 90 SH and carbopol 934 for the sustaining layer. The guaifenesin SR granules of different formulation were evaluated for bulk density, tapped density, angle of repose, Carr’s index and Hausners ratio and results were found to be 0.460 ± 0.12 to 0.515 ± 0.03 gm/cm3 , 0.550 ±0.03 to 0.590 ±0.04 gm/cm3 , 19 ±0.01 to 26 ± 0.23, 13.72 ± 0.03 to 19.56 ± 0.04 & 1.137 to 1.196, respectively. The prepared bilayer tablets were evaluated for weight variation, hardness, friability, drug content and in vitro drug release. In vitro dissolution studies were carried out in a USP 24 apparatus I. The formulations gave an initial burst effect to provide the loading dose of the drug followed by sustained release for 12 h from the sustaining layer of matrix embedded tablets. In vitro dissolution kinetics followed the Higuchi model via a non-Fickian diffusion controlled release mechanism after the initial burst release. Stability studies conducted for optimized formulation did not show any change in physical appearance, drug content, matrix integrity and in vitro drug release. The results of the present study clearly indicated that GBT was a stable dosage form and a promising potential of the guaifenesin bilayer system as an alternative to the conventional dosage forms
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
