Abstract Extensive studies have been conducted on natural materials due to their unique and biodegradable properties for oral drug delivery. In the current research, we fabricated sodium caseinate nanomicelles (NaCNs) using casein as a natural polymer to develop a controlled-release oral drug delivery system. NaCNs was explored to improve the therapeutic potential of Doxorubicin (DOX) with reduced toxicity in healthy organs. The synthesized and thoroughly characterized DOX-loaded NaCNs were subjected to in vivo anti-tumour evaluation and bio-distribution analysis in a 4T1-induced breast cancer model. Our findings indicated an almost eight-fold reduction in tumour size in the group orally treated with DOX-NaCNs when compared to free DOX. It is plausible that the enhanced anti-tumour effects of oral DOX-NaCNs is related to the controlled release of DOX from the delivery system as well as the longer circulatory time of the drug in the blood, as confirmed by the bio-distribution study, when compared with free DOX and the intravenous formulation of DOX-NaCNs. Additionally, the tumour drug accumulation for the orally administered DOX-NaCNs was 1.27- and 6.8-fold higher than that of the intravenously administered DOX-NaCNs and free DOX, respectively and overall, was 8.34-times higher than the orally administered free DOX. In comparison, the orally administered DOX-NaCNs showed significant reduction in tumour size (5.66 ± 4.36mm3) after the two doses as compared to intravenously administered DOX-NaCNs (10.29 ± 4.86 mm3) on day 17 of the experimental period. Moreover, NaCNs were well tolerated in the mice at a single dose of 2,000 mg/kg in an acute oral toxicity study. Moreover, no significant change in the body weight was observed after treatment with the single dose of NaCNs when compared to the control group. Thus, NaCNs emerge as a safe and non-toxic delivery system with excellent bio-distribution profile and high anti-tumour effects that present as a potential option for oral chemotherapy.

Route Of Delivery

Oral drug delivery is the most commonly used and preferred route of delivery of pharmaceuticals which has been successfully treating wide number of diseases. The advantages of this method of delivery are patient friendly, cost effective, established delivery system, noninvasiveness and convenient, and In the pharmaceutical field it is the most favored drug delivery system. Oral drug delivery systems along with other effective delivery system types that are effective and promising are discussed in this paper based on the mechanism of drug release.

Human Beings

The subcutaneous injection of insulin for the treatment of diabetes mellitus can lead to patient non-compliance, discomfort, pain and local infection is a chronic metabolic health disease affecting the homeostasis of blood sugar levels in human beings. Oral route of drug delivery system has been the most widely accepted means of drug administration other than invasive drug delivery systems. For the development of an oral insulin delivery system, we have to focus on overcoming the various gastro-intestinal barriers for insulin uptake from the gastrointestinal tract. To overcome these barriers various types of formulations such as insulin conjugates, micro/nanoparticles, liposomes, hydrogel, capsule, and tablets are designed to deliver insulin orally. Various potential ways to administer insulin orally has been explored over years but a fluctuating level of insulin release have been recorded. A number of advancement has taken place in the recent years for understanding the needs of improved oral delivery systems of insulin. This review article concentrates on the challenges for oral drug delivery of insulin as well as various carriers used for the oral drug delivery of insulin and also provides the relevant information about the clinical tested formulations of oral insulin and its patents.

Increasing Demand

The convenience of administration and improved patient compliance are important in the design of oral drug delivery system which remains the preferred route of drug delivery inspite of various disadvantages. Fast disintegrating tablets (FDTs) have received ever-increasing demand during the last decade, and the field has become a rapidly growing area in the pharmaceutical industry. The popularity and usefulness of the formulation resulted in development of several FDT technologies. These techniques render the disintegration of tablet rapidly and dissolve in mouth in five seconds without chewing and the need of water which is advantageous mainly for pediatrics, geriatrics and patients having difficulty in swallowing tablets and capsules. Formulation of a convenient dosage form for administration, by considering swallowing difficulty and poor patient compliance, leads to development of orally disintegrating tablets. Conventional preparation methods are spray drying, freeze drying, direct compression, Molding, and sublimation while new technologies have been developed for the production of orodispersible tablets. Keywords: Fast Dissolving Tablet, drug delivery system, fast disintegrating, fast melting.
