Solid dispersion extended-release system involves amorphization of drug material that leads to creating an alternative pathway for poorly water-soluble drugs. The drug increases solubility due to an increase in apparent solubility of the particular drug. Crystalline lattices of the drug are disturbed during its manufacture, which minimizes the crystal packing energy for solubilization. Along with this, molecular level dispersion with the carrier increases the dissolution rate. Different challenges are involved in this type of system. Supersaturation creates the separation of solute and solution, causing it to be thermodynamically unstable. Recrystallization due thermodynamically unstable state of the system causes Intramatrix recrystallization. Agglomeration, polymer hydration and clumping of the system lead to the prevention of dissolution of non-ionic, amorphous active drugs. Various manufacturing processes such as mechanical stress, downstream processing, etc., significantly impact the performance of the drug systems. Despite these issues, approaches for SDS have been used to overcome these challenges. They are based on hydrophilic polymers, hydrophobic polymers, wax, and lipids systems. At present, the perfect SDS isn’t readily...

In recent years, natural products such as Boswellic acids (BAs) have attracted researchers around the globe because of their significant potential against various diseases without any toxic effects. Boswellic acids, which belong to the pentacyclic triterpenes type of class, are extracted from the gum-resin portion of Boswellia serrata and many other different species such as Boswellia sacra, Boswellia papyrifera, and Boswellia carterii. The Boswellic acids obtained from these species are broadly classified into two categories as α-Boswellic acids and β-Boswellic acids. The six major recognized acids which are obtained from the gum resinous extract of Boswellia serrata and Boswellia carterii includes α-Boswellic and β-Boswellic acids, acetylated α-Boswellic acids and β-Boswellic acids and 3-O-acetyl-11-keto-β-Boswellic acid and 11-keto-β-Boswellic acid. In recent years, several biological potentials of Boswellic acids have been investigated, including inhibition of inflammation, anti-arthritic, anti-microbial, anti-diabetic, anti-asthmatic, anti-cancer, etc. In addition to leukotriene inhibiting property, the Boswellic acid and their analogues also possess the potential to be used against inflammatory bowel disease and neurodegenerative diseases. The most common are...

Silymarin is a mixture of flavonolignan and polyphenolic bioactive natural products found in the milk thistle plant Silybum marianum. It has anti-oxidant, anti-inflammatory, anti-cancer, and antiviral activities potentially useful in treating several liver disorders, such as chronic liver diseases, cirrhosis and hepatocellular carcinoma. However, the benefits are curtailed by its extremely poor water solubility (<50 μg/mL), low bioavailability and poor intestinal absorption. To solve these problems, nano-based technological strategies appear to be a promising method to potentiate therapeutic action. The purpose of this study is to review the different nanostructured systems available in the literature as delivery strategies to improve the absorption and bioavailability of...

Conventional dosage forms are the systems that don’t have complete control on their drug release, and also there is no control over the effective concentration at the target site. So in order to overcome this problem the osmotic drug delivery system was developed for the controlled delivery of drugs. This osmotic drug delivery system includes dosage forms for oral administration and implantable systems where they provide controlled delivery of drugs. These systems contain osmotic agents and a semipermeable membrane where they play an important role in the development of these delivery systems. This review mainly concentrates on the main Advantages, the principle of osmosis and how the drugs are delivered by using osmotic pressure, historical background, Types of osmotic drug delivery – Implantable and oral osmotic system, their pictorial representations and mechanisms, factors influencing the drug release, scientific developments and Marketed products of osmotic drug delivery...

The prevalence of infectious diseases in the world, including in Indonesia, has increased significantly. One of the factors of death due to infectious disease is decreasing the human body’s immune system. Therefore, studies on immunomodulatory agents need further investigation. Many studies have shown that secondary metabolite compounds contained in plants have immunomodulatory properties. These compounds are flavonoids, alkaloids, polysaccharides, phenols, terpenoids, tannins, glycosides, saponins, and sterols. In Indonesia, there are many types of medicinal plants containing secondary metabolite compounds. Besides, Indonesian people usually consume Jamu for immune-boosting. Jamu is made from Indonesian traditional herbal medicine such as ginger, turmeric, galangal, Curcuma, cinnamon, sand ginger, lemongrass, cardamom, tamarind, lime and cloves. The most frequently used Indonesian traditional herbal medicine investigated regarding their constituents and immunomodulatory effect should be explored. Although, more research is needed to prove efficacy and assure safety scientifically. This paper aims to give comprehensive views useful for future development and further improve its utility as immunomodulatory...
