Paracetamol is mainly used as analgesic and antipyretic drug. This study was conducted to evaluate the binding property of Irvingia gabonensis gum (IGG) in paracetamol tablet formulations in the presence of either maize starch or microcrystalline cellulose as disintegrant. IGG was isolated by acetone precipitation of the filtrate from the maceration of the powdered seeds of Irvingia gabonensis (Irvingiaceae) in distilled water for 24 h. Paracetamol granules were prepared using the wet granulation method. They were produced by using various concentration of IGG as binder, maize starch or microcrystalline cellulose as disintegrants and lactose as filler. The different formulations of paracetamol granules were mixed with magnesium stearate and talc and compressed into the respective tablets. The tablets were evaluated based on uniformity of weight, tablet hardness, friability, disintegration time and in vitro drug release. The tablet hardness for the paracetamol tablet formulations ranged from 2.27±0.09 to 8.00±0.54 Kgf. The friability values ranged from 0.21 ± 0.04 to 3.40±0.10%. The disintegration time ranged from 3.00±0.10 to 23±0.50 min. Tablets from all the formulations released up to 70% of their paracetamol contents within 25 min. For all the formulations, as the binder concentration increased the rate of drug release decreased. For tablets prepared using IGG as binder; formulations that contain microcrystalline cellulose as disintegrant had better release profile than those prepared using maize starch as disintegrant. The study shows that IGG have good binding property. Paracetamol tablets formulated using IGG as binder have comparable hardness value but lower disintegration time than those formulated using maize starch mucilage as binder.
Protracted oral Naproxen administration for acute and chronic conditions, such as rheumatoid arthritis treatment, may cause peptic ulcers. The topical application of Naproxen will circumvent this effect. This research aims to assess the physicochemical, anti-inflammatory and analgesic properties of Naproxen-loaded niosomal gels formulated using Brachystegia eurycoma gum (BEG) as the gelling polymer. BEG was isolated by acetone precipitation of filtrate produced by cold maceration of Brachystegia eurycoma seeds powder. Naproxen and BEG compatibility was evaluated using Fourier transform infrared FTIR) spectroscopy. Naproxen-loaded niosomes were produced with cholesterol, surfactant (tween 80) and water using a modified ethanol injection method. The formulated niosomes were incorporated into either BEG (5, 7.5 or 10%) or HPMC (1.5, 5%) gel base to produce the respective Naproxen-loaded niosomal gels. The niosomal gels were assessed for their physicochemical, antiinflammatory and analgesic properties using a commercially available gel as a positive control. There was no incompatibility between BEG and Naproxen. The formulated gels' pH ranged from 6.4 to 7.3, while the viscosity ranged from 1476.2 to 2980 mPas. The formulated gels had good extrudability and spreadability compared to the commercially available gel (1%). In-vivo studies using white albino rats showed that gels from the optimized formulation (F1) had comparable anti-inflammatory (26.5% inhibition) and analgesic properties to the commercially available gel (31.3% inhibition). Naproxen-loaded niosomal gels having good physicochemical, analgesic and anti-inflammatory properties were successfully formulated using BEG as a gelling agent.
Malaria is a major health concern in children aged less than five years old, globally. In Nigeria, it was estimated that 300,000 children die annually from malaria. Thus, this study aims to evaluate the clinical response of a brand of arthemether-lumefantrine (AL) for clearing parasitaemia in children aged less than five years old. This was a prospective study of the clinical and parasitological responses to the treatment of uncomplicated Plasmodium falciparum (P. falciparum) malaria using a popular dispersible brand of AL 20/120 mg. A hundred participants within 6–59 months with P. falciparum malaria were enrolled in the study and participants who could not complete the follow-ups were excluded. The drug was administered to participants following same dosage regimen on days 0, 1, 2 and followed-up on days 3, 7, 14, 21 and 28 in which the participants were assessed clinically and parasitologically. Data was analysed using MS-Excel 2010 and SPSS version 18. Kaplan-Meier survival analysis was used to assess clinical outcomes. The study showed that 73 participants completed the 28 days follow-up while 27 participants were lost to follow-up. Clinical outcome revealed no early treatment failure (ETF), one late clinical failure (LCF), 10 parasitological failures and 62 adequate clinical and parasitological response (ACPF). Clinical response was 84.9%, cumulative success and failure rate was 93.6% and 6.4%, respectively, on day 28. The clinical response of AL was efficacious. The failure rate of 6.4% could likely be as a result of reinfection within the period of follow-up.
Malaria is an epidemic with 1.3% reduction in annual per capital economic growth rate. This study was to assess physicians’ antimalarial utilization in children below five years and conformity to guidelines. This is a retrospective and cross-sectional random sampling of prescriptions of antimalarials in under five between January 2012 and December 2014 in the secondary facility and January 2012 to December 2017 in two health facilities. Data was recorded using WHO indicator forms and analyzed using SPSS. Exactly, 800 prescriptions giving a total of 1,243 and 1313 drugs were prescribed in the Secondary Facility (CH), Warri and Primary Health Care (PHC), Oria respectively with an average of drugs prescribed per encounter (DPPE), CH (3.1 ± 0.01) and PHC, (3.3 ± 0.1). Antimalarials, were the most prescribed. Generic prescription was more in PHC (59%) than in CH (58%). Syrups were most prescribed 70.96% in CH, Warri and 53% in PHC, Oria. However, 27(50.9%) of physicians based prescription on experience, 13(24.5%) and 4(7.5%) followed WHO and National Antimalarial Treatment Policy (NATP) guidelines respectively while (17.1%) on the efficacy of the antimalarial. The antimalarial utilization practices conform to the WHO guidelines although there are lapses. Prescription was predominantly based on experience.
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.
