RESUMO

BACKGROUND: Antimicrobial stewardship (ASP) is considered a key prevention strategy in addressing the worldwide concern of accelerating antimicrobial resistance. Limited research is available regarding healthcare providers' knowledge and attitude toward antimicrobial stewardship and the barriers for its implementation. METHODS: The present cross-sectional study was conducted on pharmacists and healthcare prescribers (HCPs) in different hospital sites across Jordan. A validated survey was used to evaluate HCPs and pharmacists' knowledge, and attitudes towards ASP and the barriers for its implementation. Logistic and linear regression were conducted to identify the factors associated with knowledge and attitude toward ASP, respectively. RESULTS: A total of 603 participants, 69 (11.4%) pharmacists and 534 (88.6%) HCPs completed the study questionnaire, with a response rate of 80.4%. The overall mean knowledge about ASP was 7.16 out of 10, ranging from 0 to 10 (SD 2.22). Being a pharmacist and increased awareness/familiarity about ASP were associated with improved ASP knowledge. The overall average attitude score was = 3.8 ± 0.49 (range: 1.8-4.8). Results revealed that being a pharmacist and improved knowledge were associated with improved attitude toward ASP. Lack of specialized staff with expertise in ASP and lack of access to education and training programs were the major barriers hinder ASP implementation. CONCLUSION: Despite the reasonable knowledge and the positive attitude toward the ASP, several barriers were reported, particularly by the pharmacists. Therefore, promoting the presence of adequately skilled healthcare personnel, creating easily accessible online courses, and establishing a comprehensive database of ASP resources are all suggested approaches to improve the application of ASP in healthcare settings.

RESUMO

Parkinson's disease (PD) is a debilitating neurodegenerative disease primarily impacting neurons responsible for dopamine production within the brain. Pramipexole (PRA) is a dopamine agonist that is currently available in tablet form. However, individuals with PD commonly encounter difficulties with swallowing and gastrointestinal motility, making oral formulations less preferable. Microneedle (MN) patches represent innovative transdermal drug delivery devices capable of enhancing skin permeability through the creation of microconduits on the surface of the skin. MNs effectively reduce the barrier function of skin and facilitate the permeation of drugs. The work described here focuses on the development of polymeric MN systems designed to enhance the transdermal delivery of PRA. PRA was formulated into both dissolving MNs (DMNs) and directly compressed tablets (DCTs) to be used in conjunction with hydrogel-forming MNs (HFMNs). In vivo investigations using a Sprague-Dawley rat model examined, for the first time, if it was beneficial to prolong the application of DMNs and HFMNs beyond 24 h. Half of the patches in the MN cohorts were left in place for 24 h, whereas the other half remained in place for 5 days. Throughout the entire 5 day study, PRA plasma levels were monitored for all cohorts. This study confirmed the successful delivery of PRA from DMNs (Cmax = 511.00 ± 277.24 ng/mL, Tmax = 4 h) and HFMNs (Cmax = 328.30 ± 98.04 ng/mL, Tmax = 24 h). Notably, both types of MNs achieved sustained PRA plasma levels over a 5 day period. In contrast, following oral administration, PRA remained detectable in plasma for only 48 h, achieving a Cmax of 159.32 ± 113.43 ng/mL at 2 h. The HFMN that remained in place for 5 days demonstrated the most promising performance among all investigated formulations. Although in the early stages of development, the findings reported here offer a hopeful alternative to orally administered PRA. The sustained plasma profile observed here has the potential to reduce the frequency of PRA administration, potentially enhancing patient compliance and ultimately improving their quality of life. This work provides substantial evidence advocating the development of polymeric MN-mediated drug delivery systems to include sustained plasma levels of hydrophilic pharmaceuticals.

RESUMO

Background: Artificial intelligence (AI) is the capacity of machines to perform tasks that ordinarily require human intelligence. AI can be utilized in various pharmaceutical applications with less time and cost. Objectives: To evaluate community pharmacists' willingness and attitudes towards the adoption of AI technology at pharmacy settings, and the barriers that hinder AI implementation. Methods: This cross-sectional study was conducted among community pharmacists in Jordan using an online-based questionnaire. In addition to socio-demographics, the survey assessed pharmacists' willingness, attitudes, and barriers to AI adoption in pharmacy. Binary logistic regression was conducted to find the variables that are independently associated with willingness and attitude towards AI implementation. Results: The present study enrolled 401 pharmacist participants. The median age was 30 (29-33) years. Most of the pharmacists were females (66.6%), had bachelor's degree of pharmacy (56.1%), had low-income (54.6%), and had one to five years of experience (35.9%). The pharmacists showed good willingness and attitude towards AI implementation at pharmacy (n = 401). The most common barriers to AI were lack of AI-related software and hardware (79.2%), the need for human supervision (76.4%), and the high running cost of AI (74.6%). Longer weekly working hours (attitude: OR = 1.072, 95% C.I (1.040-1.104), P < 0.001, willingness: OR = 1.069, 95% Cl. 1.039-1.009, P-value = 0.011), and higher knowledge of AI applications (attitude: OR = 1.697, 95%Cl (1.327-2.170), willingness: OR = 1.790, 95%Cl. (1.396-2.297), P-value < 0.001 for both) were significantly associated with better willingness and attitude towards AI, whereas greater years of experience (OR = 20.859, 95% Cl (5.241-83.017), P-value < 0.001) were associated with higher willingness. In contrast, pharmacists with high income (OR = 0.382, 95% Cl. (0.183-0.795), P-value = 0.010), and those with<10 visitors (OR = 0.172, 95% Cl. (0.035-0.838), P-value = 0.029) or 31-50 visitors daily (OR = 0.392, 95% Cl. (0.162-0.944), P-value = 0.037) had less willingness to adopt AI. Conclusions: Despite the pharmacists' positive willingness and attitudes toward AI, several barriers were identified, highlighting the importance of providing educational and training programs to improve pharmacists' knowledge of AI, as well as ensuring adequate funding support to overcome the issue of AI high operating costs.

RESUMO

Hydrogel-forming microarray patches (HF-MAPs) are used to circumvent the skin barrier and facilitate the noninvasive transdermal delivery of many hydrophilic substances. However, their use in the delivery of hydrophobic agents is a challenging task. This work demonstrates, for the first time, the successful transdermal long-acting delivery of the hydrophobic atorvastatin (ATR) via HF-MAPs using poly(ethylene)glycol (PEG)-based solid dispersion (SD) reservoirs. PEG-based SDs of ATR were able to completely dissolve within 90 s in vitro. Ex vivo results showed that 2.05 ± 0.23 mg of ATR/0.5 cm2 patch was delivered to the receiver compartment of Franz cells after 24 h. The in vivo study, conducted using Sprague Dawley rats, proved the versatility of HF-MAPs in delivering and maintaining therapeutically-relevant concentrations (> 20 ng·mL-1) of ATR over 14 days, following a single HF-MAP application for 24 h. The long-acting delivery of ATR suggests the successful formation of hydrophobic microdepots within the skin, allowing for the subsequent sustained delivery as they gradually dissolve over time, as shown in this work. When compared to the oral group, the use of the HF-MAP formulation improved the overall pharmacokinetics profile of ATR in plasma, where significantly higher AUC values resulting in ∼10-fold higher systemic exposure levels were obtained. This novel system offers a promising, minimally-invasive, long-acting alternative delivery system for ATR that is capable of enhancing patient compliance and therapeutic outcomes. It also proposes a unique promising platform for the long-acting transdermal delivery of other hydrophobic agents.

RESUMO

In this work, we introduce, for the first time, novel hybrid microneedle patches with implantable poly(lactic-co-glycolic acid) (PLGA) tips aligned with hydrogel-forming microneedle bases (HFMB) using a dissolvable material. A model dye, Nile red, and an antifungal drug, amphotericin B, were loaded into the PLGA tips in a controlled manner by multiple castings. Three different types of pre-formed microneedle bases including conventional dissolving baseplates (MN0), HFMB with needle heights of 600 µm (MN6) and HFMB with needle heights of 800 µm (MN8) were investigated. Compared to the conventional dissolving baseplate (MN0)-based PLGA tipped implantable microneedle design, the addition of the pre-formed HFMB (MN8) improved in vitro and ex vivo insertion capacities of the patches, increased ex vivo drug delivery efficiency up to 80% of the loaded drug and speeded up the implantation process to within 1 min. An adhesion test indicated that the hydrogel baseplate used in this study was easier to peel off from the skin than the dissolving baseplate. In vitro release studies demonstrated that the release of amphotericin B from the drug loading PLGA tips lasts for a week. Antifungal tests of the inserted amphotericin B loaded PLGA tips revealed their antifungal effects against Candida albicans. The MN8 did not dissolve, leaving no viscous residue but absorbed water and disintegrated after immersion into water. The hybrid PLGA-tipped microneedle system will be ideal for rapid implantation and sustained release of amphotericin B for dermal fungal infections. This hybrid patch design is a novel promising technology for delivering drug-eluting microimplants into the skin while ensuring easy and complete removal of the HFMB. It could have many potential applications in implantable intradermal drug delivery.
