Can METHAZOLAMIDE and ACETAZOLAMIDE be used 'interchangably'?

I have been unable to locate methazolamide where I am but there is
quite a bit of acetazolamide around.  Can these two categories of
drugs be used interchangably?

Thank you in advance,

Mehtazolamide seems to work better and has fewer side effects, though they are
similar in action.

Thank you very much.  I will talk to my GP in HK about that.  Last
time he recommended me to take Lasix after failing to locate
methazolamide.  For the past few days, I have been taking 20 mg of
Lasix every other day or on only the 'bad' day.  The outcome has been
that a 'bad' day continues to be as noisy as it was before but is no
longer associated with anxiety and discomfort like how it was
previously.

I have been experiencing the discomfort from this 'positional'
pressure on the left side of my head for the past 6 months and found
the use of diurectics to be able to release it.

I would appreciate, and my ENT doctor too, if you could share your
educated judgement on _what_ causes this pressure.  My ENT doctorS and
other doctorS here in China have been subscribing, by their training,
to the view that all the troubles of my T have come from the poor
blood circulation in the inner ear and I have been led into the path
for the past 6 months.  It is about time I would like to be
enlightened by a different view.

Thank You in advance,

FP

there is an enzyme called the carbonic anhydrase enzyme. It works in the
kidney, eye and inner ear to put fluid into a chamber. Methazolamide and Diamox
work on this enzyme so less fluid is put into the inner ear. Combined with low
salt high potassium diet, this can be theraputic. The pressure you feel is
actually the fluid pressure in the inner ear.

Thank you so much.  My doctorS here in Hong Kong and in the mainland
are more interested in making money than in continuing education and
are too much so to have advised me on this.

On the rationale presented above, would you say it is better to use a
diurectic that restricts the input of fluid into the ear than a
diurectic like Lasix that takes fluid out?

I personally never use Lasix as it is not a carbonic anhydrase inhibitor.

Thank you very much one more time.  I suppose there is no need to
check with my GP who prescribed Lasix to me after failing to find
methazolamide. I could just go ahead to consult an eye specialist here
in China on how to take this medicine.  Diamox is mostly prescribed by
eye doctors.  When I told my ENT doctor about using DIAMOX, he was so
surprised as if he had discovered something celestial.

I am beginning to feel that somehow a visit to a Chinese doctor
trained in western medicine here in China carries the same elements of
risk as a visit to a WASP doctor who, after taking a few courses in
herbalist medicine, begin to practice herbal treatments in the
US...LOL/

This is not a reflection on your doctor at all. My methods are based on my
understanding of physiology and not on the textbook, so there is no reason for
your doctor to know my methods.

I have the pills here.  The eye doctor said DIAMOX has to be taken
with sodar pills and pills that replace potassium loss, and cited me a
few unpleasant side-effects.

More questions before starting the treatment:
(1)For tinnitus patients, how should these pills be taken; once a day
or twice a day.  Could I do it every other day?  etc..  The eye
specialist and the ENT doctors here are not aware that DIAMOX could be
used to treat T patients. I have bought the 0.25 mg pills.
(2)How long should the treatment last?  Is this a lifetime commitment?
(3)What would you tell me in addition to the above before I start.

Thank you in advance,

FP

Diamox is not a cure for tinnitus. when there is hydrops or increased fluid
pressure in the inner ear, it is what I use to lower that fluid pressure.
There are as many causes of T and there are eye conditions.

After talking to his books and professor, my ENT doctor in China is
still scratching his ball on this 'hydrops' thing.  His simple mind
suggests to him that if a patient is not experiencing vertigo or
dizziness, where on earth  that 'hydrop' comes from!  On the other
hand, he has once again failed to explain why the use of diurectic has
been successful in releasing the positional pressure on the left side
of my head.

So he is not encouraging at all on the use of Diamox.  As a matter of
fact, he does not think I need Lasix too.  Lasix was prescibed to me
by a Hong Kong doctor upon *my* request for a pill that could release
my head pressure without creating a 'stedio effect' like Dyazide.
Prior to that he prescribed me to take prosac for the release of that
pressure.  Thus for the time being I will try to get by with Lasix.  I
take 20 mg of Lasix on the 'bad' day only.  The good thing about this
diurectic is that it allows me to habituate more easily on a bad day.
That is to say, the noise is still there on a bad day but is no longer
associated with anxiety and tense feeling.  And there is no 'stedio
effect' like Dyazide. In addition, the use of this diurectic has
helped the bowel movement.

Before you lose patience with me, let me ask you one more time to help
me and my doctorS in China shed some light onto this puzzle.  The
puzzle is about this positional pressure in my head travelling from
side to side, and in doing so creating a phenomenon of one good day
being followed, quite regularly, by a bad day which is to be followed
by another good day again.  Would it be possible that this 'positional
pressure' i have been complained about comes from body parts other
than the inner ear???

Thank you in advance,

FP
p.s.  Would appreciate if you could send me an email aside from
replying to my post on the ng.  Somehow the software at Google and the
ISPs in China don't click that well.

The problem is: while the GP that recommends me to take Lasix is an
Oxford guy in Hong Kong and speaks with authority, my ENT doctor in
China that 'finally' suggests me to 'try out' Diamox speaks like a
whimp as he is not well versed in western medicine.  I have no
confidence with him.  When I return to NA, I will make an effort to
visit your clinic.

Thanks,

FP
