Need a source for Bonoste

All it is is potassium bicarbonate; it's a tablet that you dissolve in water.
I've checked Isseg, Simi, Francisco de Asis, and a couple of other drug stores, and none of them have it.
I originally got it from the IMSS pharmacy. However, they won't give me a refill unless I have a prescription for it. It't not worth that amount of trouble.
So, anybody know where I can buy this stuff.

I know you said you tried Similares, but this sure looks like the same stuff.

More than once I've had to show the Similares clerks a webpage from their own website.

I managed to find something called Corpotasin CL at Farmacia Guadalajara. The chemical makeup is a bit different, but the important thing is, it contains potassium.
It's not cheap, by Mexican standards; 380 pesos for 50 tablets. I got the original Bonoste from IMSS for free.
