Review of Modified Oral Solid Drug Delivery System and Recent Active Patents

Abstract

Background: A tablet is a solid dosage form containing active pharmaceutical ingredients (API) and various excipients. Different procedures, such as direct compression of powder mixtures, and dry and wet granulation technologies, are used to create distinct types of tablets. Tablet development is aided by technological advancements in the form of modified-release tablets. Objective: The modified release dosage form can be manufactured to obtain a specific pharmaceutical profile, the specific site of action and reduce the number of dose administrations using a variety of coating technologies. For modified released drug delivery, various sorts of patents are explored. The review's primary goal is to provide information on modified release formulations, formulation methodologies, current active patents based on modified release, and tablet coating technologies. Conclusion: The tablet is a common and convenient pharmaceutical dosage form. Recently, modified release drug administration has largely supplanted traditional tablet drug delivery technologies. The chrono pharmaceutical drug delivery can also involve modified drug delivery. Modified release tablets are used to boost the therapeutic impact of medicine by targeting the location of action on the illness condition. Modified-release tablets are very handy, easy to create, cost-effective, and do not require high-cost equipment, and they are gaining in popularity these days. Patents for modified-release tablet dosage formulations that are currently active were also discussed.
