HaHaHa lol.

Although on some drugs it makes less difference than others, all medications
are not the same. Just ask your pharmacist/chemist.  Do they ever have a
patient controlled on a brand name medication who then goes on a generic and
suddenly the medication doesn't work as well.  Almost every pharmacist can
tell you stories of this happening to patients.    Most high end brands,
have better quality control.  have tablets that have more consistent
liberation, and absorption characteristics.  They use well proven excipients
and disintegration formulae.  Try taking a brand name tetracycline capsule
and a generic not made by a brand company.  Take the capsules and see how
they dissolve in solutions of different pH's.   You will probably find a
difference.  My father-in-law loved his fords and would not trade them in
for a mercedez.  So again its peronal choice.
