静脉注射的优点就是快速静脉注射药物的分布在整个身体。通常,这些药物总是快速代谢，快速排出，导致短期的临床疗效。大家可以从微丸持续释放显效得皮启发。具体看链接：https://www.innocentive.com/ar/challenge/9933723
Intravenous delivery allows for the rapid distribution of injected drugs from the veins throughout the entire body. Oftentimes, these drugs are quickly metabolized and excreted resulting in short durations of clinical efficacy. Certain therapies may benefit from a bolus followed by sustained release. The Seeker wishes to identify a technology to sustain the delivery of a human high dose intravenous drug from a single injection administered over a period of 15 to 30 minutes.
This Challenge requires only a written proposal.

Challenge Overview
An intravenous sustained drug delivery technology is desired for a high dose drug that needs to be delivered over 8 to 10 hours. This intravenous sustained release delivery technology would allow a bolus of drug (approximately 40 to 60%) to be delivered quickly upon intravenous administration followed by the remaining dose (60 to 40%) delivered in a near zero order fashion from this intravenous administration over an 8 to 10 hour interval. This drug delivery technology needs to use materials that are already recognized as safe or can be easily qualified for parenteral administration in humans. This drug delivery technology should present no encumbrance to nurses administering the drug in a hospital setting. This technology should be amenable to delivering about 2 grams of a drug with an aqueous solubility of approximately 0.75 grams in 50 mL at 25°C and approximately 1 gram in 50 mL at 37°C during the 8 to 10 hour interval.
Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on March 21, 2015. Late submissions will not be considered.
