The internet giant hopes the legal proceedings filed on Tuesday will deter phony pharmacies from violating its ad policies by selling illegal drugs on Google.
The company, on its blog, said there had been an increase in rogue pharmacies advertising illegal and potentially harmful drugs. However, Michael Zwibelman, Google's litigation counsel, said it would continue to invest time and money to stop the harmful practice.
Zwibelman said: "In recent years, we have noticed a marked increase in the number of rogue pharmacies, as well an increasing sophistication in their methods.
"This has meant that despite our best efforts, from extensive verification procedures, to automated keyword blocking and changing our ads policies, a small percentage of pharma ads from these rogue companies is still appearing on Google.
"Rogue pharmacies are bad for our users, for legitimate online pharmacies, and for the entire e-commerce industry."
