Question

Which of the following are applications of Nano particles?

• A. Targeted drugs may be developed
• B. Various routes of administration including oral, nasal, injection, intra-ocular (within the eyes) etc. can be used.
• C. The size and surface characteristics of nanoparticles can be easily manipulated. This could be used for both passive and active drug targeting
• D. All of the above

Answer 1

Answer: (D)

All of the above

• The size and surface characteristics of nanoparticles can be easily
  manipulated. This could be used for both passive and active drug targeting
• Nanoparticles can be made to control and sustain release of the drug during the transportation as well as the location of the release.
  Since distribution and subsequent clearance of the drug from the body
  can be altered, an increase in drug therapeutic efficacy and reduction in side effects can be achieved.
• Choosing an appropriate matrix also helps in increasing the efficacy and reducing side effects
• Targeted drugs may be developed
• Various routes of administration including oral, nasal, injection, intra-ocular (within the eyes) etc. can be used.
• Hence option D is correct.
