What are the alternatives to animal testing?

SADFHorde asked:


When researchers need to develop a drug or medication that will ultimately benefit multitudes of people, they turn to certain animals for tests and trials.

Animals have provided us with many answers regarding a vast amount of human diseases of illnesses over the years. As a famous ad once said: “They’ve saved more lives than 911.”

For those of you who are opposed to all forms of animal testing, would you please give suggestions or alternatives to these methods? I’m sure many of you already have some good ideas.
