Pharmaceutical Applications of Glucose Syrup from High Quality Cassava Flour in Oral Liquid Formulations.

Pharmaceutical oral solutions are preparations in which the active ingredients are dissolved in suitable liquid vehicles such as syrups. This study sought to determine the potential of glucose syrup produced from high quality cassava flour (HQCF) as a vehicle or sweetener in the preparation of paracetamol syrup and simple linctus. Four formulations (two paracetamol syrups (B1 and B2) and two simple linctus formulations (A1 and A2)) were prepared using glucose syrup from HQCF as vehicle or sweetener while two controls (B3 and A3) were prepared for each group using sucrose syrup as vehicle or sweetener. Two brands of paracetamol syrup and simple linctus were purchased from retail pharmacies to serve as standards. Physical and organoleptic parameters such as pH, taste and color, microbial load, and drug content of all formulations were determined. All formulations passed the microbial load and drug content tests as specified by the British Pharmacopoeia. The paracetamol syrups were all sweet with characteristic bitter aftertastes except formulation B2 which was sweetened with sucralose. All the simple linctus formulations were sweet except A2 (sweetened with sucralose) which was very sweet. The taste masking capacity of the glucose syrup produced from HQCF matched that of the sucrose syrup in the products formulated. Therefore, glucose syrup from HQCF could be a suitable alternative to sucrose syrup as a vehicle or sweetener in oral liquid formulations and can ultimately reduce the cost of these oral liquid formulations.

Utilization of Pectin from Okra as Binding Agent in Immediate Release Tablets.

Polymeric materials from plants continue to be of interest to pharmaceutical scientists as potential binders in immediate release tablets due to availability, sustainability, and constant supply to feed local pharmaceutical industries. Paracetamol tablet formulations were utilized in investigating the potential binding characteristics of pectin harnessed from various okra genotypes (PC1-PC5) in Ghana. The pectin yields from the different genotypes ranged from 6.12 to 18.84%w/w. The pH of extracted pectin ranged from 6.39 to 6.92, and it had good swelling indices and a low moisture content. Pectin extracted from all genotypes were evaluated as binders (10, 15, and 20%w/v) and compared to tragacanth BP. All formulated tablets (F1-F18) passed the weight uniformity, drug content, hardness, and friability tests. Based on their crushing strength, tablets prepared with pectin from the various genotypes were relatively harder (P ≤ 0.05) than tablets prepared with tragacanth BP. Tablets prepared with pectins as binders at 10%w/v and 15%w/v passed the disintegration and dissolution tests with the exception of PC4 at 15%w/v. Incorporation of pectin from all genotypes (excluding PC5) as a binder at concentrations above 15%w/v (F13, F16, F14, and F15) produced tablets which failed the disintegration test and showed poor dissolution profiles. Thus, pectin from these genotypes can be industrially commodified as binders in immediate release tablets using varying concentrations.

The Role of the Patient Information Leaflet in Patients'Medication Therapy: A Case Study within the Kumasi Metropolis of Ghana.

One of the tools used in providing comprehensible medication information to patients on their medication use for improved adherence and subsequent optimal therapeutic effect is the Patient Information (PI) leaflet. In Ghana, the patient information leaflet is available through various sources including health-care professionals (HCPs) and electronic forms. The World Health Organization (WHO) estimates that more than 70% of patients, especially in the developing countries, who receive medications do not read the accompanying leaflet. This study assessed the role of the patient information leaflet in Patients' medication therapy in the Kumasi metropolis of Ghana. A random cross-sectional survey was conducted in various hospitals and pharmacies within selected districts in the Kumasi metropolis. The survey revealed that 96.9% of the sampled respondents (n = 300) were provided with PI leaflets on their medicines while only 3.1% of them indicated otherwise. Among the proportion of respondents who were provided with PI leaflets, 66.7% of them read the information on the drug leaflets whilst the remaining 33.3% did not. Ultimately, 62.4% of those who read the PI leaflets were influenced to discontinue their medication. In conclusion, reading of the drug information leaflet was higher than that found in previous studies in Ghana. Reading the leaflet did not increase adherence but aroused anxiety and decreased adherence in some patients. A large number of the patients who were given the PI leaflets indicated that it did not provide them with the needed information.
