NANOPARTICULATE DRUGS

• Elan-NanoSystems™ technology reduces the particle size of a poorly water soluble drug from a several micron particle size to a 50+ nanometer size

• Reduction in particle size results in an increase in surface area

• Increased active agent surface area results in faster dissolution of the active agent in an aqueous environment,

•Faster dissolution generally equates with greater bioavailability, smaller drug doses, less toxicity, and other benefits

Present status of nano business

• Private Nanobusiness was born only in 1997• Global 2003 - 3 Billion USDollars• Expected 5 – 225 Billion US Dollar• Market Value of Nano products 2008 – 700 billionUS Dollar 2015- 1 Trillion US Dollar• Expected Patents in 2015More than 300

6000 CorporateCompanies Invited

Current Global Scenario of Activity In nanotechnology

Future ofNanotechnology

• National Science and TechnologyCouncil (USA) claims that:

“Nanotechnology is an enabling technology that will change the nature of

almost every human-made object in the next century.”

Future of nanotechnology

Potential Risks of Nanotechnology• Health issues– Nanoparticles could be inhaled, swallowed, absorbedthrough skin, or deliberately injected– Could they trigger inflammation and weaken theimmune system? Could they interfere with regulatorymechanisms of enzymes and proteins?• Environmental issues– Nanoparticles could accumulate in soil, water, plants;traditional filters are too big to catch them• New risk assessment methods are needed– National and international agencies are beginning tostudy the risk; results will lead to new regulations
