Organogel as a system was to estimate its capacity to delay and slow the drug release in the duodenum. The gelators, 12HSA (12-hydroxystearic acid), span 60. span 40 were used; the castor oil (CO) and anise oil (AO) also represented the liquid phase. To achieve the goal of this work was by using diclofenac sodium (DS). Organogels specifications were by estimating thermal attitude using tabletop rheology and differential scanning calorimetry (DSC). The organogel strength study was by applying oscillatory rheology tests the amplitude sweep and the frequency sweep. Realizing the morphology of the organogel was done utilizing an optical microscope. CO and AO binding capacity was also manifested. The transition temperatures for all organogels were reversible. Imaging demonstrated spherulites aggregates for organogels of 12HSA and span 40 in CO and AO while span 60 organogels in both oils existed as fibers aggregates. Furthermore, organogels exhibited viscoelastic characteristics as 20 wt% 12HSA in both oils were frequency-independent. The results revealed that the HPMC capsule containing the organogel resisted the dissolution in the acidic media for two hours. Moreover, organogels slowed the release of DS for 24 hours in an alkaline medium. Finally, all the selected organogel in CO exhibited a high oil binding capacity.

Helicobacter pylori (H. Pylori) is one of the most common infectious human pathogens. H. pylori could induce inflammation, that causes illnesses and disorders of upper gastrointestinal which including peptic ulcer diseases, dyspepsia, gastroesophageal reflux disease and gastric mucosa-associated lymphoid tissue (MALT) lymphoma. It is important to use a better tolerated and greatly effective eradication regimen. In this study, 75 newly diagnosed adult patients with H. pylori infection were included and completed the study, they were allocated into three groups with three different treatment regimens for H. pylori eradications; Group A (25 patients) received oral standard clarithromycin-based triple therapy for 14 days. Group B (25 patients) received oral bismuth based-quadruple therapy for 10 days. Group C (25 patients) received oral moxifloxacin-based triple therapy for 14 days. The results reported in this study indicated a significant higher eradication rate of Group B and Group C (84% and 80%, respectively) of patients with H. pylori infections compared to that of Group A (52%). The incidence of adverse effects were appeared as 72%, 64% and 24% of patients in group A, B and C respectively. The use of moxifloxacin triple regimen for H. pylori eradication, present with eradication efficacy parallel to that of quadruple regimen which were significantly higher compared to that of clarithromycin triple regimen. Also moxifloxacin triple therapy is more tolerable and does not increase the incidence of overall adverse effects compared to other regimens used in this study.
幽门螺杆菌(Helicobacter pylori, H. pylori)是人类最常见的感染性病原体之一。幽门螺杆菌可引起炎症,引起上消化道疾病和紊乱,包括消化性溃疡疾病、消化不良、胃食管反流病和胃黏膜相关淋巴组织淋巴瘤。重要的是采用一种耐受性更好和非常有效的根除方案。本研究纳入75例新诊断的成人幽门螺杆菌感染患者并完成研究,他们被分为三组,采用三种不同的治疗方案根除幽门螺杆菌;A组(25例)接受口服标准克拉霉素三联疗法,疗程14天。B组(25例)口服以铋为主的四联疗法,疗程10天。C组(25例)采用口服莫西沙星三联疗法,疗程14天。本研究报告的结果表明,B组和C组幽门螺杆菌感染患者的根除率(分别为84%和80%)显著高于a组(52%)。A、B、C组不良反应发生率分别为72%、64%、24%。莫西沙星三联方案根除幽门螺杆菌的效果与四联方案相当,且明显高于克拉霉素三联方案。此外,莫西沙星三联疗法的耐受性更强,与本研究中使用的其他方案相比,不会增加总体不良反应的发生率。

Fluoxetine (FX) is an antidepressant drug administered only orally in humans. Despite the wide use of FX, until now, there is only limited literature concerning the pharmacokinetics (PK) of FX and the effect of food on its PK. Thus, the objective of this investigation was to study the PK of FX in Arabic healthy male adult volunteers under fasting and fed conditions. In the fasting study, FX 20 mg capsules (Prozac®, Eli Lilly, Canada) were administered to 41 volunteers after overnight fasting of 12 hours, followed by blood sampling from each volunteer immediately before dosing (zero time) and then at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 24, 36, 48, 60, 72, 96, 120, and eventually at 144 hours after FX dosing. The fed study was conducted after 90 days wash-out period following the completion of the fasting study. The same subjects who received FX in the fasting study were administered the drug directly after a fatty breakfast (fed study), followed by blood sampling intervals similar to the schedule mentioned above for the fasting study. The current investigation demonstrated no statistical differences in the FX pharmacokinetic parameters Cmax, AUC0–t, AUC0–∞, Kel, T1/2, MRT, Cl/F, and Vd/F after fasting compared to the fed conditions, whereas there was statistically significant elongation in the Tmax values after food intake. Therefore, this study concludes the absence of food effect on the PK of FX (except Tmax) in the Arabic population and confirms the method of administration mentioned in the product information but also concludes high interindividual variation in FX exposure (AUC), which suggest that therapeutic drug monitoring (TDM) might be advisable when feasible.

High percentage of the Iraqi population profoundly rely on folk medicine to meet their health needs which makes their safety questionable. This study aims to evaluate Iraqi herbalists' knowledge and practice to ensure the public's safety. This study was conducted in a cross-sectional design between October 2021 and March 2022, using a pretested questionnaire administered to Iraqi herbalists practicing in Middle Euphrates Area. Through face-to-face meetings, participants completed a multicomponent questionnaire comprising 15 items in four sections. The data obtained were analyzed using a statistical package for social sciences; Chi-square was used to correlate some variables, and P-values of <0.05 were considered significant. A total of 54 male herbalists from five Iraqi provinces joined this survey, the majority practicing in Kabala. Most herbalists had 10- 20 years of experience, and more than 50% had a university degree. Data showed that 72.2% of herbalists identify their herbal items using their own experience, and 35.2% use this experience as their sole source of knowledge. Only 35.1% use herbal books in conjugation with their experiences, and a few (1.9%( use multiple sources of information. Herbalists with more years of experience (79.6%( evaluate patient conditions properly, follow up (40.7%(, and refer patients to their physicians when needed (42.6%(. Although fifty percent of herbalists educate their patients regarding the storage condition of remedies, most of them refrain from writing the complete ingredients on their final product regardless of their experience. Results also showed that most herbalists do not have a record tracking adverse reaction. Most Iraqi herbalists lack the proper system for prescribing and dispensing their remedies and adequately identifying the sold herbs. The study showed a variation in practice among herbalists using approaches based mainly on their experience.

There were several goals in this study, the most important of which was to create an oral liquid preparation (Ion sensitive floating oral in situ gel system for sustained delivery of Montelukast Sodium for pediatric patients) that would make administration easier, provide the correct therapeutic dose, and allow the drug to be released more slowly into the digestive tract (GIT) for better control. Montelukast Sodium in situ gels at different concentration (w/v) of natural polysaccharides (Gellan gum and sodium alginate) and natural polymer (Pectin) were prepared and characterized in the terms of preparation, viscosity and In vitro release. As the concentrations of ion-sensitive gel-forming components (Gellan gum, sodium alginate, and pectin) and gas-generating ingredients increased, the viscosity of formulations in solution (CaCO3). In vitro release study showed that the release of Montelukast Sodium from these gels was characterized by an initial phase of high release (burst effect), followed by a more gradual release in the second phase. The oral distribution of Montelukast Sodium using the in situ gel system manufactured by Montelukast Sodium can be seen as a viable strategy for the improvement of therapeutic effects.

Routine vaccination activities, such as detection, reporting, and management of adverse events following immunization (AEFIs), are generally handled by healthcare providers (HCPs). Safe vaccines against severe acute respiratory syndrome coronavirus (SARS-CoV-2) were introduced to control the Coronavirus Disease-19 (COVID-19) pandemic. The study aimed to assess the knowledge, perceptions, and practice of HCPs in Iraq about reporting adverse events following COVID-19 vaccination, and their association with sociodemographic variables. The study was a cross-sectional study that was carried out between August and September 2021 at the COVID-19 vaccination centers in Iraq. This study used an online and paper-based questionnaire, which was distributed among HCPs (physicians and pharmacists) in COVID-19 vaccination centers. A total of 117 pharmacists and physicians responded to the survey. Two-thirds of respondents were pharmacists. The majority of the respondents (49.6%) had fair knowledge levels on AEFIs. The perception of 43% of the participants was very good, whereas the perception of 28%, 23%, and 6% of the participants was fair, good, and poor, respectively. The reporting practice of HCPs was inadequate in 53% of respondents. The number of pharmacists who had good knowledge of AEFIs was significantly higher than that of the physicians. The age group (30-39) years of HCPs was significantly associated with more positive perception towards AEFIs. The number of pharmacists that had good perception was significantly higher than that of the physicians. Furthermore, HCPs aged 30 to 39 years had significantly higher reporting practices than other age groups. The study highlighted that the HCPs working at the COVID-19 vaccination centers have low knowledge of AEFIs. On the other hand, HCPs had more positive perception towards reporting AEFIs. Education programs and reference materials are needed to increase their awareness about AEFIs.

Nefopam (N.F.) HCl is a non-narcotic centrally-acting, non-opioid benzoxazocine analgesic to relieve acute and chronic pain. It exhibits low bioavailability (about 36%) due to its first-pass degradation in the liver. Intranasal administration has been used as a new route for targeting active brain sites and enhancing the bioavailability of N.F. HCl bypassing hepatic metabolism. In situ gel of N.F. HCl was prepared by the cold method using different concentrations of Poloxamer 407, Poloxamer 188, HPMC K4M, Carbapol 934, and Hyaluronic acid polymers. The results show that identification tests are superimposed with references, solubility study shows that N.F. HCl is suitable to be administered intranasally; Compatibility studies reveal incompatibility of Nefopam HCl with HPMC K4M and Carbapol 934; meanwhile, no interaction with Methylcellulose and Hyaluronic acid. In conclusion, the obtained results revealed the incredible ability of the produced N.F. HCl intranasal in situ gel is intended to enhance drug bioavailability bypassing the metabolizing effect of the liver that N.F. HCl is facing when given orally.

The use of antibiotics without prescription (self-medication) is growing globally and is associated with increased bacterial resistance, ineffective treatment and adverse reactions. This study aimed at assessing the practice of antibiotic self-medication in the Iraqi population. A cross-sectional study design was adopted in this work. The sample was comprised of 303 staff members from the non-medical colleges in Iraq. An online questionnaire was distributed between the 29th of June to the 14th of September 2021 to collect data including socio-demographic characteristics and questions about antibiotic self-medication. Most of the participants had a university degree and a moderate monthly income. The majority (88%) have practiced self-medication at least once before. A “simple” condition and convenience were the main motivators behind self-medication, which was mainly used for sore throat, fever and cough. Own experience was the most reported determining factor for selecting an antibiotic, and community pharmacies were the main source for obtaining the antibiotics. About 40% of the participants admitted to switching the antibiotic or changing its dose during the treatment course. Self-medication with antibiotics is a major issue in our community and measures have to be taken to reduce its impact on public health through the development of bacterial resistance.

This study aimed to develop an oral drug delivery system for gastro-retentive sustained drug release of baclofen by using a 3D printed capsular device since baclofen has a short half-life of 2.5 to 4 hours and has a narrow absorption window. Firstly sustained-release tablets of baclofen were formulated through the hot-melt extrusion of various thermoplastic polymers and direct compression of the extrudate, then a capsular device was designed and 3D printed to contain two air pockets to enable floating of the device and has four windows for drug release. 3D printing of the capsular device was done by an FDM printer using biodegradable PLA filament, and the sustained release tablets were inserted into the device to allow the medicine to be released into the stomach over a longer period. An in vitro buoyance test and an in vitro dissolution test were used to examine the buoyancy and sustained-release features of the formulated gastro-floating system. Five sustained release formulas were developed using different thermoplastic polymers in hot-melt extrusion. Produced tablets were assayed for drug content, hardness, and friability while a DSC study was done on the selected formula. F 5 which contains 20% baclofen, 55% Eudragit RS-100, 20% ethylcellulose, and 5% PEG 4000 showed sustained release where the complete dissolution of the drug occurred in 12 hours, and the gastro-floating device remained floating all the time. This method has a great potential for developing various floating drug delivery systems with the required release profile.

This research concentrate on cultivated Iraqi Agave attenuata dried leaves and roots, because of little studies on this plant especially on the root that lead to the eager of study and comparison of phytochemical constituents between leaves and root. Extraction of bioactive constituents was carried out using several solvents with increasing polarity (n-hexane, ethyl acetate and methanol) by soxhlet apparatus. Steroidal saponins in Agave genus is well documented in many species, lightening the minds in this research on extraction method which is specific for steroidal saponins. Phytochemical screening was done by GC/MS for n-hexane fraction, qualitative and quantitative estimation of several bioactive constituents (caffeic acid, p-coumaric acid, and quercetin) for ethyl acetate and methanol fractions while for steroidal saponins (sarsasapogenin, hecogenin and tigogenin) in both leaves and root by using reverse phase-high performance liquid chromatography (RP-HPLC). Among those identified phytochemical constituents, several constituents have not been detected in Agave attenuata leaves and roots before. This study is the first to describe the results in which the highest concentration of caffeic acid was found in leaves ethyl acetate fraction, p-coumaric acid and quercetin in root ethyl acetate fractions. While for steroidal saponins, the hecogenin, tigogenin and sarsasapogenin highest concentrations were found in leaves.
