Need Help Identifying Pills

[Pacome]

Hi, can someone help me identify these pills, and what does the text say?

Although health related, this will probably be better in the Thai language forum.

 

Moving it there.

Fenac-pyridine.  I'm presuming that's diclofenac, an antiinflamatory drug.

 

One tablet twice a day after food.

It seems unusual to mix pills like that in a pharmacist's sachet, but here seem to be 2 different pills in there, a white oblong one and a circular yellow one.
ฟีแน็ค as mentioned, is likely diclofenac.
However ไพริดีน (pyridine) as written is toxic and not used as a medicine. Additionally, diclofenac contains no pyridine ring structure.
Maybe it's short for  ฟีนาโซไพริดีน (Phenazopyridine), a drug  used to alleviate the pain, irritation, discomfort, or urgency caused by urinary tract infections, surgery, or injury to the urinary tract. ฟีนาโซไพริดีน certainly comes up as the first Google hit for ยา ไพริดีน.
Phenazopyridine has the trade name ไพริเดียม which could be confused with ไพริดีน.
