Use of Box–Behnken design for optimization of compounded medication: acyclovir capsules report

Campus compounding pharmacies play an important role in public health. Herpes simplex is one of the most common viral diseases in humans, which generates a great demand for acyclovir capsules in compounding pharmacy. It is well known that the formulation's components influence the effectiveness of the drug. The objective of this study is to show the applicability of Box-Behnken design in optimization of a compounded formulation and to evaluate the effect of excipients on dissolution and drug content in acyclovir 200 mg capsules produced at UFF´s University Pharmacy (FAU). The formulations were prepared and evaluated for average weight test, uniformity of dosage units and in vitro dissolution, while meeting pharmacopoeial specifications. A statistical analysis showed that sodium starch glycolate, Aerosil®, influences drug content and dissolution results. Magnesium stearate shows no influence on the dissolution at different concentrations but influences the assay results. A numerical optimization was applied to adjust the formulation variables based on the foresaid responses, accomplishing the best formulation that will be prepared and dispensed at FAU upon medical prescription.

PHARMACEUTICAL EVALUATION AND POST-MARKET SURVEILLANCE STUDY OF THREE BRANDS OF LISINOPRIL TABLETS IN SUDAN

Background: Lisinopril is a type of angiotensin-converting enzyme (ACE) inhibitor that used to treat high blood pressure (hypertension) in adults and children. The safety and efficacy of drug products can be assured when their quality is consistent and reproducible. To ensure the requisite quality, pharmaceutical companies are required to test their products during and after manufacturing and at various intervals during the shelf life of the product. Methods: The aim of this study was to study and evaluate the physicochemical and pharmaceutical parameters in order to confirm the pharmaceutical quality of the generic Lisinopril tablet formulations available in Sudan. Evaluation was done based on the compendia physicochemical and pharmaceutical evaluation parameters. Different brands of Lisinopril 5mg tablets purchased randomly from drug stores, and coded Z, L and A, were assayed for weight uniformity, friability, hardness, disintegration, dissolution rate using standard physical methods, and also the similarity is studied to compare brand of originator to the generic products. Their percentage drug contents were determined using standard UV Spectrophotometric method. Results: All the brands being studied comply the pharmacopoeial specifications for weight uniformity, friability, disintegration and dissolution. The dissolution profile shows more than 80 % release in 30 minutes. Additionally, all brands should similarity factor above 50% and therefore to be consider as similar. Quantitatively, all the three brands being tested do complied with the pharmacopoeial specifications for drug content. Conclusion: Hence this study will serve as a tool in assessing the pharmaceutical quality and to monitor post market quality, safety and efficacy of Lisinopril tablet formulations. Peer Review History: Received 18 January 2021; Revised 13 February; Accepted 3 March, Available online 15 March 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.

Development and Evaluation of Chewable Tablets of Calcium and Vitamin D

The aim of research work was to prepare a formulation of calcium and vitamin D chewable tablets by wet granulation method using excipients and to evaluate the tablet properties. In this research work vitamin D3 was used as vitamin D. The blend was compressed on a rotary compresson machine. Tablets were subjected to various tests (weight variation, thickness, hardness and assay of calcium and vitamin D3 etc) and the results were in compliance with the pharmacopoeial specifications. All physical properties studied indicate that all excipients are good pharmaceutical excipients for tablets. The aim of this work was to minimise the complexity of formulation and to make cost effective product. Since tablets to be prepared are chewable so sweetening and flavouring agents are to be incorporated to make the tablet palatable and easily acceptable.

In Vitro Quality Evaluation of Ciprofloxacin Tablets Marketed in Dessie, Ethiopia

Good quality medicines are a prerequisite for a successful treatment. Post marketing surveillance is very crucial to ensure product quality and eliminating substandard products to be distributed and, consequently, ensure better patient clinical outcome. Hence, this study assesses quality of six brands of ciprofloxacin tablets marketed in Dessie, Ethiopia using in vitro quality control tests. Weight variation test, disintegration test, dissolution test and assay for the content of active ingredients was done according to United sates Pharmacopoeia, 2007. The percentage content of ciprofloxacin tablets were within the range of 90-110% and the disintegration time was found between 2.375- 6.31 minutes. In addition, ciprofloxacin tablets released more than 80% of the drug after 30 minutes. Hence, all brands of ciprofloxacin tablets met the quality control parameters as per United States Pharmacopoeial specifications.
