A 10-year literature review of different nano-formulations of RSV

Route of administrationDrug (API)ExcipientFormulationObservationsReference
Parenteral delivery (intravenous)trans-RSVTPGSSLNShowed 9.37 folds higher plasma half-life and improved circulation time, better passive brain delivery of drug in Charles Foster rats.[56]
Oral deliveryRSVMagnesium dihydroxideSolid dispersionImproved solubility and bioavailability (3.3-fold) as compared to RSV alone.[87]
A mixed lipid phase (castor oil/Capmul MCM 1:1) and a mixed surfactant phase (Kolliphor EL/Kolliphor RH 40 1:1)Self-micro emulsifying drug delivery system (SMEDDS)Formulation improved the bioavailability and reduce toxicity which is further used in the supplement as well as the pharmaceutical industry.[88]
poly (DL-lactide-co-glycolide) (PLGA)Systematically optimized nanoparticlesKa and AUC are 7.17 and 10.6 folds respectively while bioavailability showed 2.78 folds.[89]
Phospholipids, Sylysia 350, TPGSSolidified phospholipid-TPGSIncreased bioavailability by dissolution rate and absorption.[90]
ZeinNano capsulationImproved bioavailability and permeability of 1.15 folds.[91]
Di stearoyl phosphatidyl choline, sodium taurocholate, cholesterolProliposomal formulationAUC and Cmax increased by 2 folds.[92]
Nasal deliveryRSV8.75% w/v chitosan solution, SLMs, chitosanLMs uncoated or coated with chitosanImprove Cmax (60 min) about 9.7 ± 1.9 μg/mL.
Effective targeting of brain drug delivery by nasal route.
[93]
TransferosomesIntranasal transferosome mucoadhesive gelImproved Cmax and AUC by 2.15 and 22.5 folds respectively as compared to RSV suspension alone.[94]
Topical deliveryRSVGelot 64 (surfactant), OAs and LAsNiosomesTopical penetration increased up to 21%.[86]
DendrimerDendrimer nanotechnology78.06% of the formulation showed intradermal permeation and only 37.33% RSV alone.[13]
EugenolNano emulsionThe highest RSV penetration into the stratum corneum is about 9.55 (ratio compared to saturated RSV).[95]
LimoneneNano emulsionThe highest permeation of drug to the skin is about 12.61 (ratio compared to saturated RSV).[95]

AUC: area under the curve; Cmax: peak plasma concentration; LMs: lipid microparticles
