The MSNs, which were designed for oral administration, enhanced both the dissolution rate and drug loading capacity.Methods: The use of MSNs as an oral drug delivery system was investigated by SEM, TEM, BETBJH, XRD, FT-IR, and HPLC. Additionally, we examined the oral bioavailability of BVP loaded onto MSNs and examined the cellular cytotoxicity of MSNs.Results: The results indicate that the oral bioavailability of BVP after loading onto MSNs was greater than that of a marketed product. Furthermore, we studied the mechanism by which MSNs enhance the oral absorption of BVP.Conclusion: MSNs have the potential to enhance the oral bioavailability of poorly water-soluble drugs by accelerating the drug dissolution rate.","PeriodicalId":94287,"journal":{"name":"Current drug delivery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139682294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concentration was scrutinized by light scattering techniques (UV spectrum (novel method) and Fluorometer (CL 53)).Results: The drug induction time was 20 min without polymer and 90 and 110 min with polymers, such as HPMC K15M and Xanthan Gum, respectively. Therefore, the order of the polymer's ability to inhibit nucleation was Xanthan Gum > HPMC K15M in the medium (7.4 pH). Similarly, the drug induction time was 30 min without polymer and 20, 110, and 90 min with polymers, such as Sodium CMC, HPMC K15M, and Xanthan Gum, respectively. Therefore, the order of the polymer's ability to inhibit nucleation was HPMC K15M > Xanthan Gum > Sodium CMC in SIFsp (6.8 pH), which synchronizes the polymer's potentiality to interdict the drug precipitation.Conclusion: The HPMC K15M and xanthan Gum showed the best crystallization inhibitor effect for the maintenance of superfluity conditions till the drug absorption time. The xanthan gum is based on the \"glider\" concept, and this shows the novelty of this preliminary research.

Subsequently, many antifungal agents are available to cure diseases like pemphigus, athlete's foot, acne, psoriasis, hyperpigmentation, albinism, and skin cancer. Still, they fall short due to pitfalls in physiochemical properties. Conventional medications like lotion, creams, ointments, poultices, and gels are available for antifungal therapy but present many shortcomings. They are associated with drug retention and poor penetration problems, resulting in drug resistance, hypersensitivity, and diminished efficacy. On the contrary, nanoformulations have gained tremendous potential in overcoming the drawbacks of conventional delivery. Furthermore, the potential breakthroughs of nanoformulations are site-specific targeting. It has improved bioavailability, patient-tailored approach, reduced drug retention and hypersensitivity, and improved skin penetration. Nowadays, nanoformulations are gaining popularity for antifungal therapy against superficial skin infections. Nanoformulations-based liposomes, niosomes, nanosponges, solid lipid nanoparticles, and potential applications have been explored for antifungal therapy due to enhanced activity and reduced toxicity. Researchers are now more focused on developing patient-oriented target-based nano delivery to cover the lacunas of conventional treatment with higher immune stimulatory effects. Future direction involves the construction of novel nanotherapeutic devices, nanorobotics, and robust methods. In addition, for the preparations of nanoformulations for clinical studies, animal modeling solves the problems of antifungal therapy. This review describes insights into various superficial fungal skin infections and their potential applications, nanocarrier-based drug delivery, and mechanism of action. In addition, it focuses on regulatory considerations, pharmacokinetic and pharmacodynamic studies, clinical trials, patents, challenges, and future inputs for researchers to improve antifungal therapy.","PeriodicalId":94287,"journal":{"name":"Current drug delivery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49687002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To get around some of these issues and enable the use of therapeutic pharmacological substances that wouldn't typically cross the blood-brain barrier (BBB), convection-enhanced delivery (CED) has been developed. It is a cutting-edge strategy that gets beyond the blood-brain barrier and enables targeted drug administration to treat different neurological conditions such as brain tumours, Parkinson's disease, and epilepsy. Utilizing pressure gradients to spread the medicine across the target area is the main idea behind this diffusion mechanism. Through one to several catheters positioned stereotactically directly within the tumour mass, around the tumour, or in the cavity created by the resection, drugs are given. This method can be used in a variety of drug classes, including traditional chemotherapeutics and cutting-edge investigational targeted medications by using positive-pressure techniques. The drug delivery volume must be optimized for an effective infusion while minimizing backflow, which causes side effects and lowers therapeutic efficacy. Therefore, this technique provides a promising approach for treating disorders of the central nervous system (CNS).","PeriodicalId":94287,"journal":{"name":"Current drug delivery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139565507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mortality rate of cancer patients has increased significantly worldwide in recent years. There are several treatments available, but these treatments have many limitations, such as non-specific targeting, toxicity, bioavailability, solubility and permeability problems, serious side effects, and a higher dose. Many people prefer phytomedicine because it has fewer side effects. However, amygdalin is a naturally occurring phytoconstituent. It has many harmful effects due to the cyanide group present in the chemical structure. Many scientists and researchers have given their thoughts associated with amygdalin and its toxicities. However, there is a need for a more advanced, effective, and newer delivery system for amygdalin to reduce its toxic effect. Nanotechnology has become a more refined and emerging medical approach, offering innovative ways to treat cancer.

Glioblastoma multiforme treatment includes resection tumor surgery, followed by radiotherapy and chemotherapy adjuvants. However, the drugs used in chemotherapy present some limitations, such as the difficulty of crossing the bloodbrain barrier and resisting the cellular mechanisms of drug efflux. The use of polymeric nanoparticles has proven to be an effective alternative to circumvent such limitations, as it allows the exploration of a range of polymeric structures that can be modified in order to control the biodistribution and cytotoxic effect of the drug delivery systems. Nanoparticles are nanometric in size and allow the incorporation of targeting ligands on their surface, favoring the transposition of the blood-brain barrier and the delivery of the drug to specific sites, increasing the selectivity and safety of chemotherapy. The present review has described the characteristics of chitosan, poly(vinyl alcohol), poly(lactic-coglycolic acid), poly(ethylene glycol), poly(β-amino ester), and poly(ε-caprolactone), which are some of the most commonly used polymers in the manufacture of nanoparticles for the treatment of glioblastoma multiforme.
