Interstitial Fluid Flow and Drug Delivery in Vascularized ...

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3734291/
    Interstitial fluid is a solution that bathes and surrounds the human cells and provides them with nutrients and a way of waste removal. It is generally believed that elevated tumor interstitial fluid pressure (IFP) is partly responsible for the poor penetration and distribution of therapeutic agents in solid tumors, but the complex interplay of extravasation, permeabilities, vascular ...Author: Michael Welter, Heiko Rieger

Novel targeted bladder drug-delivery systems: a review

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4664547/
    Nov 23, 2015 · Drug-delivery systems (DDSs) have been introduced to control rate, time, and place of release. Drugs can easily reach the bladder through a catheter, while systemically administered agents may undergo extensive metabolism. Continuous urine filling and subsequent washout hinder intravesical drug delivery (IDD).Author: Martino Maria Zacchè, Sushma Srikrishna, Linda Cardozo

    Recent anticancer drugs are made to be larger to selectively pass the tumor vessel and to stay in the interstitium. Understanding of the drug movement in a single molecule is indispensable to optimize drug delivery. Here we report the tracking of single nano-particles with different sizes in tumor xenografts in vivo. The motions of the nano ...Author: M. Kawai, M. Takeda, N. Ohuchi

    Jul 24, 2018 · INTERSTITIAL DELIVERY • Interstitial drug delivery can theoretically yield high CNS drug concentrations with minimal systemic exposure and toxicity. • Intracranial drug concentrations can be sustained, which is crucial in treatment with many chemotherapeutic agents. 57 58.

Mathematical Modeling and Optimization of Drug Delivery ...

    Jan 15, 2005 · Abstract. Purpose: Paclitaxel is a highly promising phase-sensitive antitumor drug that could conceivably be improved by extended lower dosing as opposed to intermittent higher dosing. Although intratumoral delivery of paclitaxel to the whole tumor at different loads and rates has already been achieved, determining an optimal release mode of paclitaxel for tumor eradication remains difficult.Author: Abraham Rami Tzafriri, Elyakum Itzhak Lerner, Moshe Flashner-Barak, Michael Hinchcliffe, Eli Ratner,...

    The feasibility of such quantifications warrants future studies to investigate drug delivery efficiency using different types of contrast agents. This study suggests that multiple‐agent delivery to the interstitial space can be efficiently assessed in vivo with both spatial and temporal analyses using the presented method.Author: Y.R.
