SUSTAINED AND CONTROLLED DRUG RELEASE SYSTEM

Controlled drug delivery systems have emerged as a result of substantial technology advancements meant to remedy the drawbacks of traditional medication delivery methods. Reducing dose frequency and allowing for sustained, controlled drug release from a single dosage form are two therapeutic benefits that these technologies may provide, which could revolutionize medication therapy. The goal of oral controlled drug delivery systems is to ensure that medications are consistently and reliably delivered to the gastrointestinal tract (GI tract) across a specific time period. It is also possible to design such systems to release drugs just at certain locations in the gastrointestinal tract, which can have either localized or systemic therapeutic effects. New methods of administering medications and other biologically active substances, known as controlled-release or sustained-release drug delivery systems, have evolved in the last several decades. When compared to more traditional formulations, these dosage forms drastically cut down on the frequency of drug administration, often by a factor of two or three. By releasing the active ingredient slowly over a long period of time, sustained-release tablets are engineered to keep medication concentrations in the bloodstream relatively constant. The treatment efficacy is improved and the variations caused by conventional dosing are minimized when plasma drug levels are kept stable. Regardless of whether they are immediate-release, sustained-release, or controlled-release formulations, all oral pharmaceutical products intended for systemic distribution must be created according to the physiological limits and peculiarities of the gastrointestinal tract
