Background:
The development of drug delivery carriers is the key area of research in the field of novel drug delivery systems. To date, a long list of carriers has been identified for this purpose but the deliveries of poorly water-soluble active substances are still facing challenges and hence, such substances are pharmacologically unsafe and economically incompetent.
Objective:
This article aims to review the applications of casein as a drug carrier and its potential for clinical use.
Methods:
The relevant literature on the casein protein was collected from authentic online scientific databases like PubMed, Scopus and Google Scholar using different keywords including "casein", "drug delivery system", "drug carrier" and "bioavailability". The articles and books accessed online have been thoroughly reviewed and the most relevant reports on casein as a drug carrier have only been included in the present study.
Results:
Casein is a milk protein that has many structural and physicochemical properties which facilitate its functionality in delivery systems. Moreover, its amphiphilic nature makes it the most suitable carrier for both hydrophobic and hydrophilic drugs without showing any toxic effects. The carriers obtained from natural sources are trustworthy over synthetic carriers and in the demand of the market due to their easy availability, low-cost factor, bio-friendly and nontoxic nature.
Conclusion:
Casein was found to be an effective natural drug carrier in various delivery systems due to its unique applications in improving the bioavailability and efficacy of a drug.

Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...
01:18Factors Affecting Protein-Drug Binding: Drug-Related Factors
One crucial factor in drug-protein binding is the drug's lipophilicity or its affinity for fat. More lipophilic drugs tend to have higher binding extents. For example, highly lipophilic drugs like cloxacillin exhibit substantial protein binding, with as much as 95% of the drug binding to proteins. In...
