B and Schnaare R. The step from in vitro to in vivo treatment of these drugs often requires development of a method of effective delivery for clinical translation. Suresh 3 , G. Here, we review the miniaturisation of drug delivery systems from the macro to nano-scale, focussing on controlled dosing and controlled targeting as two key parameters in drug delivery device design. Control over the distribution of therapeutic compounds is a complex and somewhat overlooked field of pharmaceutical research. In addition, the challenges in applying drug delivery for efficacious cancer therapy, including physical barriers, tumor heterogeneity, drug resistance, and metastasis, are discussed along with future perspectives of drug delivery in cancer therapy.

Dendrimer nanotechnology, due to its multifunctional ability, has the potential to create next generation nanodevices. Controlled-release, gastro-resistant, sustained-release or site-specific drug delivery finds a greater advantage of drugs formulated as coated pellets that can be filled into capsules or compressed into tablets. In conclusion, the investigated novel hydrogel plug could be a valuable tool for achieving desired lag time. These pellets are of narrow size distribution and can be filled into capsules. Based on the movement of molten-solid droplets, two apparatus are designed.

Physicians can help protect the appropriate medical use of prescription stimulants by considering the abuse potential of various medicines used to treat patients with ADHD, especially when these patients also have a history of nonmedical substance use. There is strong evidence that food can delay the gastric emptying of multi-particulate systems. The most commonly used drug carriers for drug delivery to GBM is described and the current drug delivery strategies for glioblastoma multiforme including possible routes through the BBB and epitopes, which can be targeted on the GBM cells is outlined.

The drug particles are dissolved or suspended in solvent, with or without binder. Fast-dissolve drug delivery systems. Improvement and advancement of these systems can maximize drugs potential and contribute to patients in the world.

Article Information

The objective of this study was to investigate a novel hydrogel plug using isolated root mucilage of Sterculia urens to obtain a desired lag time for an oral chronotherapeutic colon-specific pulsatile drug delivery of indomethacin. Human skin surface, as a site of drug application for both local and systemic effects, is the most eligible candidate available.


The invivo behavior of multiparticulate versus single unit dosage formulations. In this state liquid to the void volume ratio is low.

Depending on the laser wavelength and target material, PWs with different parameters can be generated which allows the investigation of PWs with cells and tissue. Since their introduction over 50 years ago, mulgiparticulate have been applied to nearly every industry.

In all cases, the size data was best fitted by a normal distribution. Inorganic Nanomaterials as Carriers for Drug Delivery.

There are many important diseases whose treatment could be improved by delivering a therapeutic protein to the colon, for example, Clostridium difficile multiparticulatd, ulcerative colitis and Crohn’s Disease. The GBM induced formation of a blood-tumor barrier and the consequences hereof is described and discussed with emphasis on the impact these changes of the BBB has on drug delivery to GBM.

Bulk Density and tap density affects potency of finished product, produces segregation during mixing and leads batch to batch variation. Granulator, Top-spray process is preferred when a taste masking celivery is being applied and granulation of drug s combined with excipient s. Furthermore, it provides a better alternative to traditional transdermal products due to ease mulhiparticulate product development and manufacturing.

PWs have been shown to permeabilize the stratum corneum SC in vivo and facilitate the transport of drugs into the skin. Capsules containing a combination of two MDDS with different release profile of BZ showed promising properties to improve Chagas disease pharmacotherapy in the preliminary in vivo assay performed, in which the BZ-loaded MDDS exhibited efficacy to reduce parasitemia, while decreasing the levels of liver injury markers in comparison to BZ conventional treatment.

Protease mediated drug delivery offers such a possibility. For safe and effective therapy, drugs must be delivered efficiently and with minimal systemic side effects.


Rrug the evaluation of design batches, it was observed that, even in low variation, the excipients affect the pelletization property of the blend and also the final drug release. Mucoadhesion is commonly defined as the adhesion between two materials, at least one of which is a mucosal surface.

Among specific research areas, nanoparticle size, morphology, surface area due to porosity, and chemistry controlled release kinetics are the most active. Liquid dosage forms can be accurately dosed by multipatriculate dropping tubes or oral syringes, but less precisely by dosing spoons and cups.

multiparticulate drug delivery: Topics by

This toxicity limits the maximum therapeutic dose. When swallowing a pill or receiving an injection, it is commonly assumed that drug will spread throughout the body in a more or less uniform concentration and find its way to wherever it is needed. Oro dispersible tablets containing multiparticulates with drug and rate controlling polymers. After oral administration, the water-soluble cap of capsule dissolved in the intestinal fluid and the hydrogel plug swells. The main focus is on the various formulations reported, including matrix tablets, multiparticulate formulations as pellets and hydrogel beads, and pectin-based coatings.

Calcium silicate-based drug delivery systems. In conclusion, pellets with high drug loading can be effectively manufactured and optimized systematically using QbD approach. The carriers used should be solid at room temperature and molted at its melting point.

This study, to our knowledge, is first reported investigation in which the unique thermal property of gellan gum gels, and possible interactions between a drug and counter ions of an ionotropic agent have been demonstrated through bead characterization studies.
