A Comprehensive Review on Bioavailability Enhancement of Poorly Soluble BCS Class 2 Drugs

The purpose of this review paper is to gather data from the literature about potential excipient effects on intestinal drug transit and permeability. The solubility issues complicating the delivery of these new drugs also affect the delivery of many existing drugs. Even though drug manufacturing has gotten better, some substances may not work well because they have trouble dissolving, breaking down, or being used efficiently in our bodies. This study looks into ways to make medicines work better in our bodies. We split these methods into four main plans: changing how we make the medicine, tweaking its chemical structure, using biotechnology, and finding new ways to give the medicine. The various traditional and novel techniques that that can be used for solubility enhancement of BCS Class II drugs are briefly discussed in this article. Creating new medications can be difficult if the molecules don't dissolve easily. Knowing how drugs travel in the body and their functions is crucial for producing effective medicines. The way a drug dissolves can affect its movement in the body, its interactions with proteins, and its absorption. The most popular kind of medicine that people swallow is called oral dosage forms. For a medicine to work well in the body, it should easily dissolve in water and get absorbed fast. This way, over half of the medicine can dissolve in water and enter the body smoothly. This thorough study highlights the importance of improving solubility and dissolution rate in pharmaceutical development, especially for BCS Class II medications, and offers insightful information about the various approaches and techniques used to overcome formulational difficulties and enhance medication absorption and therapeutic results. In addition, it discusses innovative methods to enhance the effectiveness of drugs, such as utilizing small technology and personalized medicine. This article is beneficial for scientists and doctors aiming to optimize patient treatment outcomes and enhance the drug development process.
