- Utilizing Biosimilars to Help Increase Patients Access and Minimize the
Financial Burden of Health Care System in Egypt
Authors: Doaa M. Abd-El-Rady et al.
Abstract: Background: Biologics have provided enhanced clinical advantages, but at expense of enormous expenditures. The exorbitant expense of biologics was somewhat mitigated by the development of biosimilars. But biosimilars market access is still recessed in many countries including Egypt. To achieve biosimilars market sustainability, countries need to evaluate the health economic barriers that biosimilars face in gaining market access.Methods: A retrospective budget impact analysis was conducted to compare the cost of biosimilars to that of their reference biologics from Egyptian regulatory perspective over a five-year period (2018-2022). Time series forecasting analysis was conducted to predict the cost savings in the upcoming five years. Finally, the study investigated local stakeholders’ perspective on the biosimilars sustainability through a specially designed online questionnaire.Results: This study provided insight into the budget impact of biosimilars in Egypt. More than 2.97 billion L.E. savings were achieved upon using biosimilars instead of their originator biologics. The predicted cost savings from biosimilars in the years (2023-2027) would grow to be more than 18.9 billion L.E. Finally, the study determined the four key insights into the policies that are essential to build a sustainable Egyptian market for biosimilars.Conclusion: The present study suggests that the introduction of biosimilars in Egypt had a positive budget impact. Cost savings are expected to grow, this could be achieved through increased competition and reduced prices

Hypothyroidism in the Egyptian Market
Authors: Nourhanne M. El-Sebaey et al.
Abstract: Background: A sizable portion of each nation's overall healthcare costs is being spent on pharmaceutical products. Hence, alternative and competing healthcare strategies or multiple brands of a specific prescription must be prioritized, especially in the case of chronic illnesses for countries with limited resources. That is why we conducted this analysis to start a series of cost variation analyses to help decision-makers, healthcare insurers, and even physicians to be well-informed and aware of the cost variation of available treatment options for optimal selection of the most convenient alternative. Objective: This analysis was conducted to determine the cost variation among levothyroxine options for hypothyroidism treatment currently available in the Egyptian market. Methodology: Ten alternatives of levothyroxine (25, 50, 100 mcg) were identified, and the corresponding prices were derived from the Egyptian Drug Authority Database. Different cost analyses were conducted through Microsoft Excel software. Results: The maximum retail cost per tablet that was observed in the branded levothyroxine 100 mcg is 0.70 EGP, while the minimum retail cost per tablet that was observed in levothyroxine 100 mcg generic medications is 0.11 EGP. The maximum cost ratio was observed between levothyroxine 100 mcg medications and was estimated at 6.364. The highest percent cost variation of 536.36% was noticed in levothyroxine 100 mcg medications compared to the percent cost variation of levothyroxine 50 mcg medications. The generic alternatives of levothyroxine 50 mcg have recorded a cost variation of 0%. Conclusion: There is a wide variation in pricing amongst generic levothyroxine in both concentrations compared to branded levothyroxine.

spectrophotometric methods for the simultaneous determination of
chlorzoxazone, paracetamol, and aceclofenac in the presence of their main
impurities
Authors: Ayoub N. Mozayad et al.
Abstract: Objective: The goal of this work is to develop and validate eco-friendly spectrophotometric methods for the simultaneous determination of chlorzoxazone (CHZ), paracetamol (PAR), and aceclofenac (ACF) in the presence of their major impurities, specifically 2-amino-4-chlorophenol (ACP), 4-aminophenol (4-AP), and diclofenac (DCF), in commercially available tablet dosage forms using chemometric techniques. Method: Six chemometric models, namely classical least squares (CLS), partial least squares (PLS) regression, and principal component regression (PCR), in addition to feed-forward back-propagation artificial neural networks (FFBP-ANN), cascade-forward back-propagation artificial neural networks (CFBP-ANN), and radial basis function artificial neural networks (RBF-ANN), were employed to analyze the synthetic mixtures, which included the cited drugs and their main impurities and degradation products, using phosphate buffer solution (pH 7.0) as the green solvent. A validation set of seven mixtures in the wavelength range of 260–302.4 nm at 0.1 nm intervals was used to validate the suggested models after they had been constructed with a calibration set of twelve mixtures. Results: The proposed multivariate calibration methods exhibited good linear relationships in accordance with the Beer-Lambert law, spanning concentration ranges of 6–19 µg mL−1 for CHZ, 8.45–24.05 µg mL−1 for PAR, and 2.4-7.6 µg mL−1 for ACF, and were validated following the ICH guidelines. The accuracy of laboratory-prepared mixtures ranged from 97–102%, with an intra-day precision relative standard deviation (R.S.D.) of less than 1% and an inter-day precision R.S.D. of less than 1.95%. Additionally, the root mean square error of prediction (RMSEP) was ≤1.0. The accuracy of co-formulated tablets was also satisfactory, with mean percentage recoveries falling within the range of 97-104.5%. Conclusion: The six suggested methods were simple, accurate, selective, quick, and eco-friendly, making them appropriate for routine analysis of the cited drugs in ternary mixtures and co-formulated tablets in quality-control laboratories.

Authors: AYINLA Maryam T et al.
Abstract: Ameliorative effect of aqueous leaf extract of Cola acuminata(ALECA) on mercury chloride- induced neurotoxicity in male Wistar rat was investigated. Thirty six (36) male Wistar rats weighing 120g-150g were randomly divided into six groups; group I: received 0.5ml normal saline; group II: received 5mg/kg body weight (b.w) mercury chloride (HgCl2); group III: received 5mg/kg HgCl2 +150mg/kgb.w ALECA; group IV: received 5mg/kg HgCl2 + 300mg/kg ALECA; group V: received 5mg/kg HgCl2 +50mg/kg N-acetyl cysteine (NAC); group VI: received 5mg/kg HgCl2 + 500mg/kg b.w Vitamin C. The animals were treated for 21days via oral route. The rats were subjected to open field test and forelimb grip test on days 14 and 21.The animals were then sacrificed and brain tissues were collected, homogenized, and centrifuged for measurement of biochemical parameters: tumor necrosis factor alpha (TNF-α) and nitric oxide (NO). The data obtained from forelimb grip test showed that muscular strength was higher in the group given ALECA, NAC and Vitamin C when compared with the group given only HgCl2(p˂0.05).The data from open field test also showed that locomotory activity and exploratory behaviour are higher while anxiety levels is lower in the group treated with ALECA, NAC and Vitamin C when compared with HgCl2group (p˂0.05). Also the levels of TNF-α and NO are lower in the group treated with ALECA when compared with the mercury chloride group (p˂0.05). From the results, it was established that ALECA treated groups compared favourably with the two reference drugs.

- A Cost Variation Analysis of Various Statin Preparations Available in the
Egyptian Market
Authors: Radwa Ahmed Ibrahim et al.
Abstract: Introduction: Dyslipidemia is one of the main risk factors for cardiovascular diseases. Statin preparations are the most effective lipid-lowering preparations that reduce the risk of mortality related to cardiovascular diseases. In the Egyptian market, various statin preparations have different strengths and prices. Aim: The current study aims to assess the percentage of cost variations among different statin medications in the Egyptian market. Methods: This is a cost variation study conducted from November to December 2022. The data were collected by using the Egyptian master on therapeutic drugs, edition 2022, and from the Egyptian Drug Database (DDB) website. The maximum and the minimum price of various statin agents were calculated. The price of each statin preparation was calculated per unit dose. The percentage of cost variations was calculated using the formula: Cost variation (%) = (maximum cost- minimum cost)/minimum cost ×100. Results: The maximum percentage of the cost variation was found between Atorvastatin preparations of 10 mg (776.9%) followed by atorvastatin agents of 20 mg (406.3%). Meanwhile, the minimum price variation was in Lovastatin preparations of 10 mg (11.1%), followed by Lovastatin of 40 mg (18.5%). Conclusion: The present study highlighted a wide range of cost variations between statin preparations, especially for Atorvastatin and Rosuvastatin. Further studies are recommended to recognize the reasons for high-cost variations among statin preparations and how to overcome those reasons. Physicians must consider the cost of the prescribed drug to improve the patients’ adherence to the treatment.

- Nanoemulsion formulation of pregabalin for enhanced nose to brain delivery
and biological tracking using radiolabeling with 99mTc
Authors: Hend Fayez et al.
Abstract: Pregabalin is a γ-aminobutyric acid analogue used for the treatment of neuropathic pain, seizures, and anxiety disorders. After oral administration, its level of brain penetration is rather modest. In this research, pregabalin was formulated successfully as a nanoemulsion. To track the biodistribution of pregabalin nanoemulsion in vivo, radiolabelling of pregabalin using 99mTc was performed. The different factors affecting radiolabeling yield were studied and radiolabelling yield of 92.6 % was achieved. A biological evaluation was performed in Swiss Albino mice through comparing biodistribution of intranasal (IN) 99mTc-pregabalin nanoemulsion with intravenous (IV) 99mTc-pregabalin solution at different time intervals. Biodistribution results show a noticeable higher brain uptake of radioactivity for IN 99mTc-pregabalin nanoemulsion compared to IV 99mTc-pregabalin solution at all time intervals. These results suggest that I.N. pregabalin nanoemulsion may be a useful strategy for enhancing pregabalin delivery to the brain.

Authors: Michael A. Kaldas et al.
Abstract: Background: Cardiovascular diseases (CVDs) are considered the leading cause of death worldwide. An important category of the CVDs is the bleeding disorders. There is a significant variation in the drug products used in the treatment of hemorrhagic disorders in the Egyptian market. Therefore, our study aims to evaluate the cost variation of different brands of antihemorrhagic drugs in the Egyptian market. Methods: The study used an analytical method to obtain the different prices of the available antihemorrhagic drug products in the Egyptian market (in Egyptian Pound), from different drug categories considering all the concentrations available. Each generic name was checked for its available products manufactured by different pharmaceutical companies, selecting those with the highest and lowest cost, calculating cost ratio and the percentage variation in prices per unit dose. Results: Among all the drugs analyzed, we found the highest percentage of cost variation was for Vitamin K1 ampoules (530.8%). Also, coagulation factor VIII 500 IU vial and 250 IU vial appeared with high cost variation percentages, which were 417.6% and 407.5%, respectively. The lowest cost variation percentages were observed in aprotinin vial and tranexamic acid ampoules, which were 13.3% and 43.6%, respectively. Conclusion: There is wide range of variation in the prices of drugs used in treating the hemorrhagic diseases in the Egyptian market. These variations should be minimized and the products should be affordable especially in the low- and middle-income countries to help improving the health states among population and decreasing the diseases economic burden and out-of-pocket expenditures.

- Spectrophotometric Resolution Methods for Determination of Dimenhydrinate
and Cinnarizine in Presence of their Toxic Impurities: Greenness,
Environmental Sustainability and Blueness Assessment Tools
Authors: Eman M. Morgan et al.
Abstract: Spectrophotometric analysis of the core drug while the coexistence of their toxic impurities is a vital analytical process. To date, there was no reported spectrophotometric method that have been reported for the simultaneous analysis of the two target drugs namely dimenhydrinate (DMH) and cinnarizine (CIN) in the presence of their most toxic impurities namely benzophenone (BZP) and 1- (diphenylmethyl)piperazine (DPP), respectively. In this study novel, green, accurate and timeless spectrophotometric analysis of a mixture of pharmaceutical drugs composed of DMH and CIN along with their toxic impurities BZP and DPP, respectively was successfully performed using smoothly applicable and costless spectrophotometric methods. Simple and easily manipulated spectrophotometric methods were introduced to simultaneously analyze the drug of interests in their pure forms, in market dosage form matrix and in prepared synthetic mixture along with their toxic impurities via ratio subtraction technique (RS) as an auxiliary resolution technique using dual wavelength (DW) method and constant multiplication (CM) method. The linearity range in all spectrophotometric methods for DMH was 6.0-60.0μg/mL while that for CIN was 3.0-30.0μg/mL. ICH guidelines were adhered in accordance with confirming validation of the presented methods where fulfilling results were accomplished. To assess the environmental impact, the Analytical Eco Scale (AES) is employed as a green evaluation tool, alongside the Green Solvent Selection Tool (GSST), the hexagon tool for sustainability assessment and Blue Applicability Grade Index (BAGI) tool. Application of these Greenness tools to the UV-spectrophotometric methods highlights their enhanced safety and efficiency in comparison with the costly, long-running, and laborious HPLC approach. This study proposes the incorporation of simple and green UV- spectrophotometric methods for conventional analysis in quality control of DMH and CIN containing formulations.

- Rosuvastatin calcium and tissue engineering; an introductory overview
Authors: Islam M. Adel et al.
Abstract: All tissues are subjected to the risk of tissue damage. Tissue damage refers to any alteration to the structure and/or the function of that tissue. To counter tissue damage, our bodies are equipped with a self-healing mechanism aiming at restoring tissue structure and function. The underlying mechanism, however, is rather poor and slow in mammalians. Moreover, in cases of severe damage, the mechanism is insufficient to repair the damage and usually, surgical intervention is mandated. For that and more, tissue engineering was conceptualized as a multidisciplinary science field in which an implantable scaffold, loaded with cells, biological cues and/or chemical agents, is utilized to stimulate tissue regeneration. Rosuvastatin calcium is a hydrophilic statin with positive effect on tissue regeneration and wound healing, besides its marketed use as cholesterol-lowering agent. Although there are several routes to drug delivery of statins (such as IV, nasal delivery, implantable delivery, … etc.), the oral route remains the most popular choice. However, owing to the poor oral bioavailability of rosuvastatin, implantable drug delivery is the go-to choice in tissue engineering. Hydrogel scaffolds are particularly favorable in tissue engineering owing to their biocompatibility, hydrophilic nature and high swelling capabilities. The whole system is effective in both soft (tendons) and hard (bones) tissue regeneration. This review sheds light on the implementation of tissue engineering as a favorable approach to wound healing with emphasis on the role of rosuvastatin in tissue regeneration.
