I can answer some of your questions about Halcion (Trialozam). Halcion is a Benzodiazpine. These drugs are used for anxiety. Halcion binds with the GABA receptors in the brain.
Here is a quick overview of the method of action of Benzos:
Your body produces many different brain chemicals. These natural chemicals (neurotransmitters) have either a "calming" or "arrousing" effect on the brain. These chemicals transmit these messages to the cells in the brain.
About 40% of the billions of brain cells respond to GABA. GABA is the brains "calming" or tranquillizing neurotransmitter. Benzodiazepine medications enhance the effect of GABA.
When one suffers from anxiety or panic attacks then the brain becomes "over-aroused" it needs the transmitters associated with the "calming" chemicals to come into action . These respond by sending messages to the brain cells to slow down or to stop and since a large portion of the brain’s cells are responsive to these transmitters there is a “calming” affect on the brain.
Benzodiazepines have similar chemicals to those produced by the body for "calming" effects and when these are added to those produced naturally by the body it means that there are a greater number of transmitters sending out messages to the brain cells resulting in an excessive slow down or shut down of these cells.
As a result of this increase in the numbers of cells being slowed down the brains output of "arousing" transmitters is reduced. However, these “arousing” transmitters are vital for normal alertness, memory, co-ordination, emotional responses, heart rate, and blood pressure.
The failure to produce enough excitatory transmitters affects the functioning of these systems and affects the bodies normal working.
Halcion is used for Insomnia but is also used as an Oral Sedative. It works very quickly (10-15 minutes). Halcion effects are usually gone within 2-3 hours after taking the medication.
It causes sedation and amnesia for the event. This medication is well tolerated and very effective for most people. You dentist might use a technique called "stacked dosing." This means you may be given an additional dose shortly after the first in order to achieve the desired level of sedation.
Most people do not remember the procedure after taking this medication and the effects are pleasant. This is the most common type of Oral sedation used in dentistry in the USA. It has a great track record of success. Your dentist might have you take a dose the night before in order to get you a good nights sleep.
I think you will be very pleased with this medication. It is a great choice for people that do not want to remember the treatment and "sleep" through it.
I hope this helps. Best wishes to you.
