MeTA stands for the medicines transparency alliance which is a multi-stakeholder alliance working to improve access and affordability of medicines to all those who are unable to access basic and essential medicines due to high cost or local unavailability.

The availability of good quality, affordable medicines is affected by several factors. The appropriate medicines have to be selected from the thousands available; then they have to be procured after involving the relevant regulatory authorities and agencies in their registration, importation or local manufacture.
