Drug Delivery Applications

Biopolymers are extensively used for developing drug delivery systems as they are easily available, economical, readily modified, nontoxic, biodegradable and biocompatible. Thiolation is a well reported approach for enhancing mucoadhesive and mechanical properties of polymers. In the present review article, for the modification of biopolymers different thiolation methods and evaluation/characterization techniques have been discussed in detail. Reported literature on thiolated biopolymers with enhanced mechanical and mucoadhesive properties has been presented conspicuously in text as well as in tabular form. Patents filed by researchers on thiolated polymers have also been presented. In conclusion, thiolation is an easily reproducible and efficient method for customization of mucoadhesive and mechanical properties of biopolymers for drug delivery applications.

Despite the extensive advancements in the field of drug delivery, the oral route remains the favorable route for administration of therapeutic actives. A success of oral controlled drug delivery systems is associated with reduced dosing frequency, decreased fluctuation in plasma drug concentration profile along with improved patient compliance. However, they are also associated with challenges like shorter gastric residence time, unpredictable gastric emptying and poor bioavailability for some molecules. This has initiated tremendous advancements in the field of gastro-retention to achieve controlled release of drugs along with improved bioavailability of drugs with narrow absorption window as well as localized action in the stomach and upper part of GIT. In present review, efforts have been envisaged to summarize our current understanding in the field of gastro-retention and their in vitro as well as in vivo characterization. Present review also highlights commercially utilized gastro-retentive technologies and some recently granted US patents in the field of GRDDS.

From the past two decades, technological advancements in science and chemistry made possible many new drug delivery systems that have the potential to completely change the course of routine therapeutic ways.  Lipid and polymer-based drug delivery systems are considered to be the pillars of many drug dosage forms, irrespective of their route of administration. With increasing knowledge on their chemistry, lipids and polymers are being modified and used as potential novel drug delivery systems with smart polymers and lipid nanotechnology paving the way for efficient drug delivery into the patient. This review article covers the swing of these drug delivery systems in the current market and interpreting all this from a health care professional’s point of view.

This paper describes the trial of making microcapsules including a bubble for shock wave drug delivery systems and evaluation of their mechanical properties. We have proposed drug delivery systems (DDS) using shock waves in order to apply micro/nano technology in the fields of biomedical engineering. In this system, a microcapsule including a gas bubble is flown in the blood vessel, and finally broken by shock induced microjet, then drug is reached to the affected part in the body as same as traditional DDS. In this paper, the mechanism for deformation and disintegration of capsules in our previous works is reviewed, and the trials of making special microcapsules are discussed. To determine Young’s modulus of capsule membrane mentioned above, the membrane is deformed by the aspiration device and the deformation is compared with computational result by FEM.
