The great efforts of many researchers have brought down some of the barriers that exist to turn a good in vitro compound into a potential in vivo drug. The advent of pharmaceutical nanotechnology has allowed an arsenal of drugs with poor stability, low solubility, high off-target toxicity and other disadvantageous features, to be accessible as pharmaceutical products that could be administered to a patient. Nanotechnology was introduced in drug delivery very long ago, but has flourished with unprecedented intensity during the last twenty years and now a diversity of nano-based preparations are at clinical stage of development or already available in the market. Undoubtedly, nanotechnology plays a key role in future pharmaceutical development and pharmacotherapy. In the first part of this review we have already discussed recent (2008-2012) patents on linear polymer-based nanosystems (nanogels, nanospheres and nanocapsules) applications to cancer therapy. Here we have expanded such analysis to branched polymers (dendrimers), self-assembling nanomicelles and lipid-based nanocarriers.
