Aripiprazole (APZ) is an antipsychotic drug that belongs to benzisoxazole derivatives and is used to treat schizophrenia as well as acute manic or mixed effects in patients with bipolar 1 disorder. APZ is used to treat certain mental, mood disorders such as bipolar disorder, Schizophrenia, Tourette's syndrome, and irritability associated with autistic disorder. It may also be used in combination with other medication to treat depression. The present review article would be useful for prospective studies for researchers interested in APZ formulation production and quality management. Using a thorough computer assisted literature survey; this review touches upon the various reported analytical methods for the quantification of APZ both in API (Active Pharmaceutical Ingredient) and pharmaceutical dosage forms. The present write-up also encompasses the various published research articles like Spectroscopy techniques, X- Ray Diffraction (XRD), Electro Chemical Technique, Differential Scanning Calorimeter (DSC) and Capillary Electrophoresis. This is the first review article in this series with focus on the analytical profile of APZ. Although, several methods were reported in the literature, HPLC stands out first for the quantification of APZ.
Aim: This study evaluates the effect of in vivo wound healing potential of Ursolic acid rich chloroform extract of Hedyotis herbacea Linn ointment using incision and excision wound model.
Study Design: Wound healing potentials of Hedyotis herbacea were analysed by Incision and excision wound model.
Place of Study: Nandha College of Pharmacy, Erode, Tamilnadu.
Methodology: Hedyotis herbacea was subjected to extraction (cold maceration), with solvents of increasing polarity. All the extracts were estimated for the presence of phytoconstituents by HPTLC. As the study has been focused on the phytoconstituent based biological activity, the Ursolic acid rich chloroform extract was chosen for the study of wound healing activity. The Chloroform extract of Hedyotis herbacea was incorporated into ointment base, to prepare the ointment. The ointments prepared with Chloroform extract (2.5% and 5%) of Hedyotis herbacea (CEHH) were subjected for evaluation of excision and incision wound model. Wistar albino rats were divided into four groups each consisting of six animals; group I (left untreated) considered as untreated control, group II treated with 5% w/w povidone-iodine ointment served as standard, group III treated with CEHH 2.5% w/w ointment, and group IV treated with CEHH 5% w/w ointment were considered as test groups. All the treatments were given once daily. Wound healing effect was assessed by the rate of wound contraction, level of total protein, Hydroxy proline, Hexosamine and Hexuronic acid and histopathology studies in an excision wound model. Tensile strength was also measured in both excision and incision wound.
Results: Wound healing activity of CEHH 5% w/w ointment treated group was greater than CEHH 2.5% w/w and untreated groups in both excision and incision wound model. The high rate of wound contraction (*P< 0.001), high tensile strength (*P< 0.001), and elevated total protein, Hydroxyproline, Hexosamine, and Hexuronic acid content were observed in animals treated with CEHH ointments when compared to the untreated control group of animals. Histopathological studies of the CEHH ointments treated groups also revealed the effectiveness in wound healing.
Conclusion: These results justified the claimed traditional use of the Hedyotis herbacea as wound healing plant.
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.
