Microencapsulation of Curcumin in Crosslinked Jelly Fig Pectin Using Vacuum Spray Drying Technique for Effective Drug Delivery

Microencapsulation of curcumin in jelly fig pectin was performed by the vacuum spray drying (VSD) technique. The VSD was advanced with a low inlet temperature of 80-90 °C and low pressure of 0.01 mPa. By the in situ cross-linking with multivalent calcium ions, jelly fig pectin produced stable curcumin encapsulated microparticles. The physiochemical characteristics of microparticles were thoroughly investigated. The results revealed that 0.75 w/w% of jelly fig pectin and inlet temperature of 90 °C could be feasible for obtaining curcumin microparticles. The VSD technique showed the best encapsulation efficiency and yield and loading efficiency was up to 91.56 ± 0.80%, 70.02 ± 1.96%, and 5.45 ± 0.14%, respectively. The curcumin was readily released into simulated gastrointestinal fluid with 95.34 ± 0.78% cumulative release in 24 h. The antioxidant activity was stable after being stored for six months and stored as a solution for seven days at room temperature before analysis. Hence, the VSD technique could be applicable for the microencapsulation of bioactive compounds such as curcumin to protect and use in the food/pharmaceutical industry.

Nanocarriers Based Novel Drug Delivery as Effective Drug Delivery: A Review

Background:

A lot of people are facing some health-related problems in day to day life. The conventional drug delivery is not able to cure it alone, moreover, some drugs have poor solubility, low half-life and show lesser bioavailability. It is necessary to conduct research on carrier-based nanoparticulate drug delivery, this is an alternative approach to alter/eliminate the problem of conventional dosing for better effectiveness, patient compliance, and effective drug targeting.

Objective:

To develop a carrier-based nanoparticulate drug delivery system for the elimination of problems associated with conventional dosage form.

Method:

In this review, different problems associated with conventional dosage form as well as potential advantages of the nanoparticulate delivery systems have been discussed. We also discussed their different route for administration such as oral, intranasal, ocular, transdermal, vaginal etc. for effective drug targeting. It has been found that different nanocarriers based drug delivery have been able to enhance the bioavailability, solubility, minimized adverse effect as well as effective in Gene delivery also. Ionic gelation, Solvent evaporation, emulsification, homogenization, lyophilisation, etc. are techniques used for their development.

Conclusion:

The carrier-based drug delivery technique act as an effective drug delivery system for the treatment of various diseases/disorders as well as provides better efficiency, bioavailability and improve patient compliance.

Slow-targeted release of a ruthenium anticancer agent from vitamin B12 functionalized marine diatom microalgae

Bio-inspired drug capsules: The synthesis of a new vitamin-B₁₂ modified biomaterial with increased static adherence properties toward cancer cell lines, allowed the targeted delivery of a poorly water-soluble ruthenium drug with an unprecedented release profile.
