What is the drug from India that is used to replace Metadone?

Apparently it is cheaper to use and patients can be weaned off Metadone and given this drug whereby they will also have the ability to be weaned completely off their drug addiction needs. There is a great deal of money to be made in the US by Pharm Companies. Methadone drug is expensive. I believe this drug is inexpensive. And "they" may not want a new cheaper methold being delivered or Medically indicated by Drug Rehab MDs for administration in the US? I am having difficulties finding the drug name by googling it. Anyone know? An MD had discussed her treatment protocals with me at one point, yet I cannot remember what the drug's name was and Police debunked her practice due to it. So, does anyone know the name of this new India made replacement for Metadone treatment?
