How are generic drugs compared to brand/patented drugs?

Generic medicines are chemically equivalent to patented medicines and are manufactured to the same safety and quality standards.
In Singapore,  the Health Sciences Authority requires the manufacturer to ensure that generics to be marketed are not just chemically equivalent, but also biologically equivalent (or bioequivalent) in the drug’s effect within the human body, usually to an acceptable limit (within +/- 20% for most medicines).
