Bipolar medication, Chiang Mai , Hua Hin

Can someone please tell me if bipolar medication, mood stabilizers  i.e. Seroquel,  Zyprexa etc. are available in pharmacies and hospitals in Chiang Mai and Hua Hin?
I also tried to look up the Bangkok Hospital in Hua Hin to see if there is a psychiatric department but it is not listed so does that mean there isn't one?
Any information pertaining to this topic will be much appreciated.

Not sure about the meds but if you are looking for a treatment center, I recommend the Dawn Rehab in Chiang Mai.
