- ItemDevelopment of mushroom polysaccharide and probiotics based solid self-nanoemulsifying drug delivery system loaded with curcumin and quercetin to improve their dissolution rate and permeability: State of the art(ELSEVIER, 2021) Khursheed, Rubiya; Singh, Sachin Kumar; Wadhwa, Sheetu; Gulati, Monica; Kapoor, Bhupinder; Jain, Subheet Kumar; Gowthamarajan, Kuppusamy; Zacconi, Flavia C. M.; Chellappan, Dinesh Kumar; Gupta, Gaurav; Jha, Niraj Kumar; Gupta, Piyush Kumar; Dua, KamalThe role of mushroom polysaccharides and probiotics as pharmaceutical excipients for development of nano-carriers has never been explored. In the present study an attempt has been made to explore Ganoderma lucidum extract powder (GLEP) containing polysaccharides and probiotics to convert liquid self nanoemulsifying drug delivery system (SNEDDS) into solid free flowing powder. Two lipophilic drugs, curcumin and quercetin were used in this study due to their dissolution rate limited oral bioavailability and poor permeability. These were loaded into liquid SNEDDS by dissolving them into isotropic mixture of Labrafill M1944CS, Capmul MCM, Tween-80 and Transcutol P. The liquid SNEDDS were solidified using probiotics and mushroom polysaccharides as carriers and Aerosil-200 as coating agent. The solidification was carried out using spray drying process. The process and formulation variables for spray drying process of liquid SNEDDS were optimized using Box Behnken Design to attain required powder properties. The release of both drugs from the optimized spray dried (SD) formulation was found to be more than 90%, whereas, it was less than 20% for unprocessed drugs. The results of DSC, PXRD and SEM, showed that the developed L-SNEDDS preconcentrate was successfully loaded onto the porous surface of probiotics, mushroom polysaccharides and Aerosil-200.
- ItemProtein and peptide delivery to lungs by using advanced targeted drug delivery(2022) Chellappan, Dinesh Kumar; Prasher, Parteek; Saravanan, Vilashini; Yee, Vanessa See Vern; Chi, Wendy Chai Wen; Wong, Jia Wei; Wong, Joon Kang; Wong, Jing Tong; Wan, Wai; Chellian, Jestin; Molugulu, Nagashekhara; Prabu, Sakthivel Lakshmana; Ibrahim, Rania; Darmarajan, Thiviya; Candasamy, Mayuren; Singh, Pankaj Kumar; Mishra, Vijay; Shastri, Madhur D.; Zacconi, Flavia C. M.; Chakraborty, Amlan; Mehta, Meenu; Gupta, Piyush Kumar; Dureja, Harish; Gulati, Monica; Singh, Sachin Kumar; Gupta, Gaurav; Jha, Niraj Kumar; Oliver, Brian Gregory George; Dua, KamalThe challenges and difficulties associated with conventional drug delivery systems have led to the emergence of novel, advanced targeted drug delivery systems. Therapeutic drug delivery of proteins and peptides to the lungs is complicated owing to the large size and polar characteristics of the latter. Nevertheless, the pulmonary route has attracted great interest today among formulation scientists, as it has evolved into one of the important targeted drug delivery platforms for the delivery of peptides, and related compounds effectively to the lungs, primarily for the management and treatment of chronic lung diseases. In this review, we have discussed and summarized the current scenario and recent developments in targeted delivery of proteins and peptide-based drugs to the lungs. Moreover, we have also highlighted the advantages of pulmonary drug delivery over conventional drug delivery approaches for peptide-based drugs, in terms of efficacy, retention time and other important pharmacokinetic parameters. The review also highlights the future perspectives and the impact of targeted drug delivery on peptide-based drugs in the coming decade.
- ItemSelf-nanoemulsifying composition containing curcumin, quercetin, Ganoderma lucidum extract powder and probiotics for effective treatment of type 2 diabetes mellitus in streptozotocin induced rats(Elsevier B.V., 2022) Khursheed, Rubiya; Singh, Sachin Kumar; Kumar, Bimlesh; Wadhwa, Sheetu; Gulati, Mónica; Anupriya, A.; Awasthi, Ankit; Vishwas, Sukriti; Kaur, Jaskiran; Corrie, Leander; Arya, K. R.; Kumar, Rajan; Jha, Niraj Kumar; Gupta, Piyush Kumar; Zacconi, Flavia C. M.; Dua, Kamal; Chitranshi, Nitin; Mustafa, Gulam; Kumar, AnkitLiquid self-nanoemulsifying drug delivery system (L-SNEDDS) of curcumin and quercetin were prepared by dissolving them in isotropic mixture of Labrafil M1944CS®, Capmul MCM®, Tween-80® and Transcutol P®. The prepared L-SNEDDS were solidified using Ganoderma lucidum extract, probiotics and Aerosil-200® using spray drying. These were further converted into pellets using extrusion-spheronization. The mean droplet size and zeta potential of L-SNEDDS were found to be 63.46 ± 2.12 nm and − 14.8 ± 3.11 mV while for solid SNEDDS pellets, these were 72.46 ± 2.16 nm and −38.7 ± 1.34 mV, respectively. The dissolution rate for curcumin and quercetin each was enhanced by 4.5 folds while permeability was enhanced by 5.28 folds (curcumin) and 3.35 folds (quercetin) when loaded into SNEDDS pellets. The Cmax for curcumin and quercetin containing SNEDDS pellets was found 532.34 ± 5.64 ng/mL and 4280 ± 65.67 ng/mL, respectively. This was 17.55 and 3.48 folds higher as compared to their naïve forms. About 50.23– and 5.57-folds increase in bioavailability was observed for curcumin and quercetin respectively, upon loading into SNEDDS pellets. SNEDDS pellets were found stable at accelerated storage conditions. The developed formulation was able to normalize the levels of blood glucose, lipids, antioxidant biomarkers, and tissue architecture of pancreas and liver in streptozotocin induced diabetic rats as compared to their naïve forms.
- ItemTargeting mucus barrier in respiratory diseases by chemically modified advanced delivery systems(ELSEVIER IRELAND LTD, 2022) Prasher, Parteek; Sharma, Mousmee; Singh, Sachin Kumar; Gulati, Monica; Jha, Niraj Kumar; Gupta, Piyush Kumar; Gupta, Gaurav; Chellappan, Dinesh Kumar; Zacconi, Flavia C. M.; Pinto, Terezinha de Jesus Andreoli; Chan, Yinghan; Liu, Gang; Paudel, Keshav Raj; Hansbro, Philip M.; Oliver, Brian Gregory George; Dua, KamalMucus gel constitutes of heavily cross-linked mucin fibers forming a viscoelastic, dense porous network that coats all the exposed epithelia not covered with the skin. The layer provides protection to the underlying gastrointestinal, respiratory, and female reproductive tracts, in addition to the organs such as the surface of eye by trapping the pathogens, irritants, environmental fine particles, and potentially hazardous foreign matter. However, this property of mucus gel poses a substantial challenge for realizing the localized and sustained drug delivery across the mucosal surfaces. The mucus permeating particles that spare the protective properties of mucus gel improve the therapeutic potency of the drugs aimed at the management of diseases, including sexually transmitted infections, lung cancer, irritable bowel disease, degenerative eye diseases and infections, and cystic fibrosis. As such, the mucoadhesive materials conjugated with drug molecules display a prolonged retention time in the mucosal gel that imparts a sustained release of the deliberated drug molecules across the mucosa. The contemporarily developed mucus penetrating materials for drug delivery applications comprise of a finer size, appreciable hydrophilicity, and a neutral surface to escape the entrapment within the cross-inked mucus fibers. Pertaining to the mucus secretion as a first line of defence in respiratory tract in response to the invading physical, chemical, and biological pathogens, the development of mucus penetrating materials hold promise as a stalwart approach for revolutionizing the respiratory drug delivery paradigm. The present review provides an epigrammatic collation of the mucus penetrating/mucoadhesive materials for achieving a controlled/sustained release of the cargo pharmaceutics and drug molecules across the respiratory mucus barrier.
