In recent years, in association with progress and innovation in the field of pharmaceutical technology, there has been an increasing effort to develop prolonged release dosage forms for many drugs. Correspondingly, a growing number of new prolonged release dosage forms have been submitted for regulatory approval. Prolonged release dosage forms have many advantages in safety and efficacy over im...

Polymeric hydrogels are common dosage forms designed for the topical administration of antimicrobial drugs to treat vaginal infections. One of the major advantages of using chitosan in these formulations is related to the intrinsic and broad antimicrobial activity exerted on bacteria and fungi by this natural polymer. Most vaginal yeast infections are caused by the pathogenic fungus Candida alb...

Formulation, Fill & Finish 2003 10 he technologies behind oral drug delivery have emerged from the mainstream pharmaceutical industry and have become influential forces in their own right, as evidenced by the burgeoning “drug delivery companies” that are at the forefront of innovation and hold their own niche market. Drug delivery companies and their pharmaceutical industry partners are poised ...

Sustained release drug delivery systems are designed to achieve a prolonged therapeutic effect by continuously releasing medication over an extended period of time after administration of a single dose. advantages of sustained release drug delivery over conventional dosage forms like improved patient compliance due to less frequent drug administration, maximum utilization of the drug, increased...

Oral solid dosage forms are the most patient-accepted and therefore industrially relevant pharmaceutical applications, representing 80% of the market share. In that context, polymer processing techniques, such as hot melt extrusion (HME) or injection molding (IM), are increasingly used to process primary material into the final dosage forms due to several benefits (e.g., enhanced solubility or ...

Specific immunotherapy involves certain drawbacks which could be minimized by the use of appropriate adjuvants, capable of amplifying the right immune response with minimal side effects. In this context, we review different types of immunotherapy vehicles and coadjuvants. We describe previous studies by our group in which we demonstrated the adjuvant capacity of Gantrez® AN nanoparticles, which...

ceutical dosage forms. They serve as carriers for drugs that are topically delivered by way of the skin, cornea, rectal tissue, nasal mucosa, vagina, buccal tissue, urethral membrane, and external ear lining (1). Because of their peculiar rheological behavior, semisolids can adhere to the application surface for sufficiently long periods before they are washed off. This property helps prolong d...

X-ray microtomography has great potential for improving the understanding of the structural features of solid dosage forms and the changes in those features during manufacturing, handling, and storage. This article describes the basic principles of the technique and provides examples of its potential applications. harmaceutical scientists have long sought the ability to see inside the solid dos...

Most common methods of delivery include the preferred topical (skin), transmucosal (nasal, buccal, sublingual, vaginal, ocular and rectal) inhalation routes. The conventional dosage forms provide drug release immediately it causes fluctuation level in blood depending upon form. Therefore to maintain concentration within therapeutically effective range needs novel system. In past few decades, co...
