The present results are encouraging for further studies and future clinical application.
Silibinin was found to exhibit a protective effect on liver and kidney after hepatic I/R injury. The present results are encouraging for further studies and future clinical application.The traditional healthcare method follows 'one-size-fits-all' criteria, which shows some limitations in rendering proper results due to varied pharmacokinetic traits of different patients. Each patient shows a different result to a set of prescribed medicines with respect to other patient. In addition, this empirical criterion is also vulnerable to develop unfavourable side-effects due to overdose or under-dose. The advancements in the field of pharmacogenetic testing has paved the way for searching solutions to achieve the goal of 'personalized medicine'. This concept has the potential to provide more effective results as compared to the traditional technique. The technology of additive manufacturing or 3D printing can cater the need of the patient-centric principle. A wide range of 3D printing techniques provide the independence to work with a number of bio-materials. This paper carries out a systematic review methodology based on the application of this novel technology in the field of drug delivery. The materials, methods of drug administration, techniques used for printing have been elaborated along with the manufacturing of polypills with varied release profiles and geometries. Certain in vivo studies has also been reported to assess the feasibility of this technology. The concept of 4D printing in this direction has also been discussed. Finally, some excerpts on estimated future scope have also been illustrated.Kangfuxin liquid (KFX) is a Chinese medicine extracted from Periplaneta americana dried worms, which presented the bioactive functions of anti-inflammation and promoting the gastrointestinal mucosal barriers repair. But the low availability of KFX exposed to the distal colon affects its therapeutic effect on ulcerative colitis. Herein, an in situ hydrogel containing KFX was designed by using temperature-sensitive poloxamer 407 (P-407) as material for rectal administration. Three KFX-P formulations with different P407 concentrations (17%, 20% and 25%) were designed and screened by detecting the gelation time, gelation temperature and mechanical strength of hydrogel. P407 in these formulations was able to be completely dissolved in KFX at 4 ℃ and then was in situ gelled at 37 ℃ to form a semisolid hydrogel. Moreover, the gelation time, the gelation temperature and the mechanical strength of KFX-P hydrogel are highly dependent on P407 concentration. With P407 concentration increasing, both the gelation time and ucosa epithelium layer, crypt, muscle layer mucosa and submucosa were also well repaired after KFX-P treatment. The strong fluorescence of ZO-1 and claudin-5 were uniformly distributed along the whole epithelial mucosa after KFX-P treatment, indicating the effective repairing of the colonic mucosal barrier. Collectively, the temperature-sensitive KFX-P for rectal delivery could effectively promote the repair of the colon mucosal barrier and inhibit the colonic inflammation in DSS-induced mice, which may be a potential strategy for UC treatment.Despite being one of the most efficacious drugs used in the treatment of basal cell carcinoma (BCC), imiquimod has limited cutaneous permeation. The current work presents the development of polyvinylpyrrolidone-co-vinyl acetate (PVPVA) microneedles loaded with imiquimod for improving intradermal delivery of imiquimod for the treatment of nodular BCC. In vitro permeation studies, using full thickness ex vivo porcine skin were used to evaluate the effectiveness of these imiquimod loaded polymeric microneedles in comparison to the topical application of commercial Aldara™ cream. HPLC analysis demonstrated similar intradermal permeation of imiquimod from Aldara™ cream and imiquimod-loaded microneedles despite the microneedle having a six-fold lower drug loading than the clinical dose of Aldara™ used for BCC management. In addition, ToF-SIMS analysis of skin cross sections demonstrated intradermal localisation of imiquimod following microneedle-based delivery while the Aldara™ treated skin showed the drug localised predominantly within the stratum corneum. ToF-SIMS analysis also demonstrated intradermal co-localisation of the PVPVA polymer, used in fabricating the microneedle, with imiquimod within the microneedle channels in a label-free manner. This study demonstrates that a polymeric microneedle system may be a viable approach to improving the intradermal delivery of imiquimod for the treatment of nodular BCC with lower drug loading.Trifluridine/tipiracil (FTD/TPI; marketed as Lonsurf®) has shown clinically relevant activity after fluoropyrimidine failure in colorectal cancer and may thus be of increased efficacy compared with current standard capecitabine chemoradiation. Here we investigated the colorectal cancer cell lines HT29, HCT116, SW48 and Caco-2 to provide a preclinical rationale for FTD/TPI-based chemoradiation treatment. BBI608 mouse All lines incorporated similar amounts of FTD, irrespective of treatment concentration and duration, then arrested in S phase, showed persistent γH2AX induction and eventually underwent endoreplication, resulting in polyploidy. Clonogenic assays performed for four combined treatment schedules demonstrated additivity for treatments given within 6 h of each other. However, 24 h FTD/TPI treatment prior to irradiation caused 1.6-2.4 fold radiosensitisation. Combined in vivo treatment was well tolerated and caused a marked tumour growth delay, similar to capecitabine radiochemotherapy regimes. Prolonged S phase arrest, persistent γH2AX signalling, endoreplication and polyploidy may contribute to the cytotoxicity of FTD/TPI. The strong radiosensitising effect observed in vitro after prolonged treatment with FTD/TPI and equivalence with capecitabine-based chemoradiation in vivo support a daily fractionated combined regime of FTD/TPI and radiation in rectal cancer treatment. This is now being tested in a phase I/II clinical trial (NCT04177602).
