literature review on sustained release drug delivery system

systems satisfy the spatial aspect of drug delivery and are also considered to be controlled drug-delivery systems5. Sustained release drug delivery systems During the past few years, conventional dosage forms of drugs are rapidly being replaced by the new and the novel drug delivery systems.

Formulations for sustained medication release are very useful in the treatment of chronic disorders. The oral route has selected matrix tablets as the most likely type of prolonged drug release.

Formulation strategy for development of the oral sustain release drug delivery system: 1. Diffusion sustained system; It involve passage of the drug molecule from the higher concentration to the lower concentration it give as, 𝐽=−𝐷 / 𝑥 Where, D is the diffusion coefficient area. dc/dx is the change of conc. 2. Dissolution sustained ...

The drug delivery system enables the release of the active pharmaceutical ingredient to achieve a desired therapeutic response. Conventional drug delivery systems (tablets, capsules, syrups, ointments, etc.) suffer from poor bioavailability and fluctuations in plasma drug level and are unable to achieve sustained release. Without an efficient delivery mechanism, the whole therapeutic process ...

Oral sustained release/Controlled release products provide an advantage over conventional dosage forms by optimizing bio-pharmaceutics, pharmacokinetic and pharmacodynamic properties of drugs and reduces dosing frequency to an extent that once daily dose is sufficient for therapeutic management. Among all drug delivery systems, oral drug delivery is the most preferred route for administration ...

The purpose of writing this review on sustained release matrix type drug delivery systems as novel drug delivery system is to compile the recent literature with special focus on maintain the desired concentration at the site with specificity. Oral sustained release products provide advantage over conventional dosages forms by optimizing

District. Phone Number: 9442787274. [email protected],[email protected],[email protected],ABSTRACTNow a days as the expenditure and problems involved in marketing new drug entities are increased, with concomitant recognition of the therapeutic advantages of Sustained release drug delivery, greater attention has been focused.

designed sustained release drug delivery system can widely reduce the frequency of drug dosing and also maintain a steady drug concentration in blood circulation and target tissue cells. 4. Total dose reduction: To treat a diseased condition less amount of total drug is used in Sustained release drug delivery systems.

Drug delivery systems (DDSs) represent an emerging focus for many researchers and they are becoming progressively crucial in the development of new treatments. Great attention is given to all the challenges that a drug has to overcome during its journey across barriers and tissues and all the pharmacokinetics modulations that are needed in order to reach the targeting sites.

SUSTAINED RELEASE SYSTEM Sustained drug delivery is that type of system which achieves a prolonged therapeutic effect by continuously releasing medication over an extended period of time after administration of a single dose.

A REVIEW ON SUSTAINED RELEASE DRUG DELIVERY SYSTEM PatilHarshalSantoshrao*, PatelNikhilbhaiDilipbhai, PatilVinay S., Bhushan R. Rane, Nayan A. Gujrathiand Sunil P. Pawar P. S. G. V. P. Mandal's College of Pharmacy, Shahada - 425409, Maharashtra, India. INTRODUCTION These are the type of controlled drug delivery

Introduction. Drug delivery system (DDS) is a generic term for a series of physicochemical technologies that can control delivery and release of pharmacologically active substances into cells, tissues and organs, such that these active substances could exert optimal effects [1, 2].In other words, DDS covers the routes of administration and drug formulations that efficiently deliver the drug to ...

Advantages of sustained release dosage forms1, 2, 3. 1) The frequency of drug administration is reduced. 2) Patient compliance can be improved. 3) Drug administration can be made more convenient as well. 4) The blood level oscillation characteristic of multiple dosing of conventional dosage forms is reduced.

Diatom biosilica-based drug delivery systems are recognized for their capability to facilitate the sustained release of conventional drugs over time. Despite this advantage, these systems often experience a significant initial burst release of the drug, which can undermine the controlled release profile.
