The type of diluent used in a formulation influences the quality of tablets produced from that formulation. The aim of this study was to evaluate the tableting properties of co-processed excipients (C-PEs) incorporated as diluents in tablet formulation by wet granulation. Metronidazole tablets were prepared by wet granulation incorporating different diluents that were either single component excipients (SCEs) (lactose and microcrystalline cellulose) or C-PEs (Ludipress<sup>®</sup>, StarLac<sup>®</sup>, Prosolv<sup>®</sup> and AVICEL<sup>®</sup>HFE). The granules obtained for each formulation were evaluated for particle size analysis, flow properties and compression properties. Tablets weighing 500 mg were compressed from the metronidazole granules on a Single Station Tablet Press using a 12 mm punch and die tooling system. The tablets were kept for 24 h post-production, and the properties of weight uniformity, thickness, tensile strength, friability, disintegration time and dissolution profile evaluated subsequently. Results of granule properties showed that variations in parameters evaluated was as a result of differences in the type and composition of diluent used in formulation. Compactibility and tabletability profile of metronidazole granules revealed a better performance with granules processed with C-PE based diluents compared to SCE-based diluents. Tablets formulated with C-PEs as diluents were uniform in tablet weight, disintegrated faster and yielded a faster drug release compared to tablet formulations containing SCEs as diluent. This study reveals the performance advantage of C-PEs as diluents in tablets manufactured by wet granulation and highlights the importance of rational selection of excipients during tablet formulation.</p> </abstract>ARTICLE2021-01-29T00:00:00.000+00:00Preparation and evaluation of an oral mucoadhesive gel containing nystatin-loaded alginate microparticleshttps://sciendo.com/article/10.2478/afpuc-2020-0009<abstract> <title style='display:none'>Abstract</title> <p>Nystatin is an antifungal agent used for prophylaxis and treatment of candidiasis, especially oral mycosis. Efficacy of nystatin conventional dosage forms is limited by the short residence time and bitter taste of the drug. This research aims at designing an optimized formulation of oral mucoadhesive gel of nystatin-loaded alginate microparticles, which can be retained in the mouth. Sodium alginate solution containing nystatin was added to the solution of calcium chloride under stirring. Microparticles containing nystatin were incorporated into the Carbopol gel. Size, loading, and release profile and mucoadhesion were investigated. The most suitable microparticles with particle size of &lt; 250 μm were prepared with alginate concentration of 1%(w/v), calcium chloride of 1%(w/v), drug:polymer concentration 1%, and ratio of alginate solution:calcium chloride of 1:10. This formulation showed 49.1% drug loading and 98.2% encapsulation efficiency. Carbopol 934 gel provided optimal mucoadhesive properties. Release profile proved a burst release, which can be attributed to the surface associated drug, followed by a slower sustained release phase for all microparticles. The developed system with ability to adhere to the oral mucosa has great appeal for treatment of localized infections and can mask bitter taste of the drug and be retained in the mouth for long periods.</p> </abstract>ARTICLE2021-03-11T00:00:00.000+00:00The potential impact of gene therapy on health-related quality of life (HRQoL) domains in haemophiliahttps://sciendo.com/article/10.17225/jhp00176<abstract><title style='display:none'>Abstract</title><sec><title style='display:none'>Introduction</title><p>Haemophilia is an inherited bleeding disorder characterised by spontaneous bleeding, often leading to impaired health-related quality of life (HRQoL). Commonly used treatments include episodic and prophylactic treatment regimens. Gene therapies could soon become available, potentially creating a paradigm shift in patient management.</p></sec><sec><title style='display:none'>Aim</title><p>This paper proposes hypotheses about the potential impact of gene therapy on HRQoL domains in haemophilia, and how these impacts might differ compared with existing treatments.</p></sec><sec><title style='display:none'>Methods</title><p>An expert working group with 10 individuals experienced in haemophilia and HRQoL research was established to discuss potential impacts of gene therapy on HRQoL in general and for specific domains in haemophilia. As part of a one-day workshop, domains of three widely used patient-reported outcome (PRO) instruments were explored: the Haemo-QoL-A, the Patient Reported Outcomes, Burden and Experiences (PROBE), and the Haemophilia Activities List (HAL).</p></sec><sec><title style='display:none'>Results</title><p>The group expected a greater improvement in HRQoL from gene therapy compared with existing treatments for the following domains: physical/role functioning, worry, and consequences of bleeding (Haemo-QoL-A); haemophilia-related health and EQ-5D-5L (part of the PROBE); leg and arm function, and leisure activities (HAL). In contrast, the experts suggested that no change or potential deterioration might be observed for the emotional impact (HAL) and treatment concerns (Haemo-QoL-A) domains.</p></sec><sec><title style='display:none'>Conclusions</title><p>Current PRO instruments in haemophilia have limitations when applied in the context of gene therapy, and no single instrument fully captures the relevant HRQoL domains. However, the PROBE and Haemo-QoL-A were considered as the most suitable existing instruments.

Of these, 58% of respondents were aged 18–45 and 136 identified as having a bleeding disorder, mostly haemophilia or von Willebrand disease. Thirteen (10%) had been diagnosed as a haemophilia carrier and a further four women were probable carriers. Prolonged or painful periods were reported by the majority of respondents; the median duration of bleeding was 7 days (range 2–42). Thirty-six per cent took time off work or study as a result and 42% reported a negative impact on social life.

When immune tolerance therapy was not possible due to financial constraints, he was treated with FEIBA prophylaxis and rituximab. The pseudotumor was managed with surgical excision. We conclude that epistaxis in haemophiliacs can be due to an underlying nasal pseudotumor, and highlight the use of rituximab for the eradication of inhibitors.</p></abstract>ARTICLE2021-03-03T00:00:00.000+00:00 Pro-Glycative Effects of Resveratrol and Caffeic Acidhttps://sciendo.com/article/10.2478/afpuc-2019-0004<abstract> <title style='display:none'>Abstract</title> <p>Resveratrol and caffeic acid belong to plant polyphenols and are known for their antioxidant effects. The aim of our research was to study their impact on Maillard reaction. This one occurs when the reducing saccharides react with amino groups of biomolecules including proteins, alter their protein conformation and transform to the variety of advanced glycation end products (AGEs). AGEs exhibit browning and generate fluorescence. There exist expectations that this oxidative protein glycosylation could be prevented by antioxidants. In this study, we incubated bovine serum albumin (BSA) with glucose for 7 days at 37°C and measured characteristic fluorescence and UV absorbance of the formed AGEs. Surprisingly, resveratrol and caffeic acid enhanced transformation of BSA to glycation products, which was confirmed either when cupric Cu(II) or ferric Fe(III) ions in nanomolar concentration were added to the system as pro-oxidant agent.</p> </abstract>ARTICLE2020-01-28T00:00:00.000+00:00Dual Loading Of Primaquine And Chloroquine Into Liposomehttps://sciendo.com/article/10.2478/afpuc-2019-0009<abstract> <title style='display:none'>Abstract</title> <p>Primaquine (PQ) has long been recognized as the only effective drug in the treatment of hepatic stage malaria. However, severe toxicity limits its therapeutical application. Combining PQ with chloroquine (CQ) has been reported as enhancing the former’s efficacy, while simultaneously reducing its toxicity. In this study, the optimal conditions for encapsulating PQ-CQ in liposome, including incubation time, temperature and drug to lipid ratio, were identified. Furthermore, the effect of the loading combination of these two drugs on liposomal characteristics and the drug released from liposome was evaluated. Liposome is composed of HSPC, cholesterol and DSPE-mPEG<sub>2000</sub> at a molar ratio of 55:40:5 and the drugs were loaded by means of the transmembrane pH gradient method. The particle size, ζ-potential and drug encapsulation efficiency were subsequently evaluated. The results showed that all liposome was produced with a similar particle size and ζ -potential. PQ and CQ could be optimally loaded into liposome by incubating the mixtures at 60°C for 20 minutes at a respective drug to lipid ratio of 1:3 for PQ and CQ. However, compared to single drug loading, dual-loading of PQ+CQ into liposome resulted in lower drug encapsulation and slower drug release. In conclusion, PQ and CQ can be jointly loaded into liposome with differing profiles of encapsulation and drug release.</p> </abstract>ARTICLE2020-01-28T00:00:00.000+00:00Antidepressant effects of valproic acid in an animal model of depressionhttps://sciendo.com/article/10.2478/afpuc-2019-0006<abstract> <title style='display:none'>Abstract</title> <p>Valproic acid, beside its anticonvulsant action, is widely used as a mood stabilizer in the therapy of bipolar disorder.

The aim of the present study was to test the effects of four tannin extracts with defined compositions on cell volume regulation and VSOR. Preparation I (98% of hydrolysable tannins isolated from leaves of sumac <italic>Rhus typhina L.</italic>) and Preparation II (100% of hydrolysable tannins isolated from leaves of broadleaf plantain <italic>Plantago major L</italic>) completely and irreversibly abolished swelling-activated VSOR currents in HCT116 cells. Both preparations profoundly suppressed the volume regulation in thymocytes with half-maximal effects of 40.9 μg/ml and 12.3 μg/ml, respectively. The inhibition was more efficient at lower concentrations but reverted at higher doses due to possible non-specific membrane-permeabilizing activity. Preparations III and IV (54,7% and 54.3% of hydrolysable tannins isolated, respectively, from roots and aboveground parts of Fergana spurge <italic>Euphorbia ferganensis B.Fedtch</italic>) inhibited VSOR activity in a partially reversible manner and suppressed the volume regulation with substantially higher half-maximal doses of 270 and 278 μg/ml, respectively, with no secondary reversion at higher doses.

In addition, eight <italic>Crataegus</italic> L. species of North America had specific markers helping for discriminative analysis from pharmacopoeial species.</p> <p><bold>Conclusion.</bold> The findings could help to identify the possible adulterations and prevent the falsification of finished products. The results will be taken into consideration during revision of the Ukrainian national pharmacopoeial monograph for hawthorn fruits.</p> </abstract>ARTICLE2020-01-28T00:00:00.000+00:00Chronopharmacology of high blood pressure—a critical review of clinical evidencehttps://sciendo.com/article/10.2478/afpuc-2019-0017<abstract> <title style='display:none'>Abstract</title> <p>Physiological functions of cardiovascular system (CVS) are exhibiting circadian patterns regulated by complex system of endogenous factors. Preserving this rhythmicity is important for its normal function, whereas disturbing the synchronization with natural day–night cycle can increase the risk of cardiovascular damage. Cardiovascular pathophysiology also follows cyclic variation; time susceptibility and period with maximum risk associated with elevated blood pressure (BP) can be predicted. Given this rhythmic nature, significant changes in efficacy between morning and evening administration of the drug may occur; appropriate timing of pharmacological intervention in therapy of hypertension may affect the efficacy of the treatment.</p> </abstract>ARTICLE2020-01-28T00:00:00.000+00:00en-us-1
