You can order these from Medisafe Pharmacy in Bangkok, and they will arrange delivery (to most locations in Thailand).
For the Atorvastatin, they sell a generic (imported from India) that is much cheaper than Lipitor/Sandoz. Unsure about the Metoprolol, best you send them a message. They usually reply within an hour and arrange prompt delivery (for Bangkok it's next day, for your location probably 2-3 days).
