Drug carriers have been generally used for drug management launch, enhancing drug efficacy and/or minimizing side-effects. Nonetheless, it’s nonetheless troublesome to get excessive loading effectivity when encapsulating tremendous hydrophilic medicine with slim therapeutic index, similar to many neurotoxins. Growing the provider proportion can enhance drug loading in a sure diploma, whereas the burst launched drug when the formulation enters the physique could trigger overdose side-effects. Furthermore, high-dose carriers themselves could enhance the metabolic burden of the physique. Therefore, new drug carriers and/or loading methods are urgently wanted to advertise the functions of those medicine. This minireview will introduce drug loading methods based mostly on particular interactions (between medicine and carriers) and can focus on the challenges and views of those methods. This work is predicted to supply different inspirations for the supply of hydrophilic medicine.
