These medications are not the same. They are both classified as non-benzodiazepines, and they are both sleeping pills, but differ slightly in chemical structure. Non-benzodiazepines are similar to benzodiazepines with regard to the mode of action, the adverse events and the risks associated with use. However, these two classes of medications are different at the molecular level which owe to the differences of their safety and tolerance.
Non-benzodiazepines are colloquially referred to as "Z-drugs" because of the starting letter of the pharmaceutical names. They are used for similar purposes, which includes their primary function as a sleeping aid for those experiencing acute or chronic insomnia. These sleeping pills are not only for those experiencing sleep maintenance issues but also for those who have a problem with sleep initiation.
In all, non-benzodiazepines have been proven to be safer and better tolerated than benzodiazepines. Even though both these classes of medications potentiated GABA activity, the newer non-benzodiazepines produce less addiction and are more selective as well. Zopiclone and other "Z-drugs" were originally marketed to be alternatives to benzodiazepines.
Both zopiclone 7.5 mg tablets and zolpidem 10 mg tablets are sedatives and depress or tranquilize the central nervous system (CNS). However, zopiclone is categorised as a cyclopyrrolone whilst the latter is an imidazopyridine.
Studies by Nakajima et al. (2000) suggested that the profiles of action of these two compounds, relating to the two major subunits of the GABAA receptor, differ (GABA, gamma-amino butyric acid, is the main inhibitory neurotransmitter found in the CNS).
The possibilities of developing tolerance to these sleep medications restricts their use to the short-term only. Zopiclone is normally used for a week or two as compared to its counterpart sedative which can be used for up to four weeks.
Both these sleep medicines were part of the first "Z-drugs" to be marketed. They generally exhibit similar efficacy in terms of their use as sleep aids but there have been differences in the side effects experienced with these medications.
In a double-blind, comparative study of these hypnotic medicines, 479 chronic primary insomniacs were evaluated for their response to these sleeping pills. Tsutsui et al. (2001) found that the improvements to sleep latency were more significant for zolpidem users than zopiclone 7.5 mg (85.8% versus 77.5%) and there were also fewer adverse events related to the use of the aforementioned sleep aid (31.3% versus 45.3%).
The study concluded that both these medicines were as effective as the other, but zopiclone was found to be less well-tolerated than zolpidem tablets and was associated with more rebound insomnia cases. This can still vary from person to person, depending on individual preference and tolerance.
Ambien is the trade name under which this sedative is marketed in the United States and most of Europe. Other brand names differ in certain parts of the world. For example, in France, this sleep medication is commonly known as Stilnox.
Different brands can work differently depending on their compositions. One of the common differences includes the rate at which the active ingredient in the tablets or capsules is dissolved. This will affect the absorption rate and hence, the therapeutic effects of the medication.
Brands tend to be more expensive than the average generic medications. In fact, they can cost approximately 80 to 85% more than their generic counterpart. This is in part due to the expired patent of the branded medication and the generic manufacturer does not have to invest the capital into the invention or patenting of the medicine.
The generic version of the brand, Ambien, is named after the active ingredient of the sleeping pill. They are both used for the same purpose - as sedatives - but differ in their costing and packaging etc.
Ambien is primarily used to help insomnia sufferers sleep better. There are different formulations which promote different aspects of sleep. The immediate-release Ambien tablets are known for their fast action. These tablets release the active ingredient quickly and the therapeutic benefits can be observed with half an ago of administration. This sleeping pill is ideal for those who have trouble falling asleep.
For those who have difficulty staying asleep, in other words, if waking up too early is an issue, Ambien CR can be an effective solution. Ambien CR is an extended-release form of the sleep aid and the effects can last longer than the fast-acting form. The main ingredient is slowly released in the body over a period of time and allows for longer lasting sedation throughout the night.
There are also sublingual tablets of zolpidem which are lower dosages of the sedative ingredient and can be used for middle-of-the-night awakenings. These tablets are available in generic versions as well.
Other mild therapeutic actions of this sleep aid involves its anticonvulsant, muscle relaxant and anxioloytic properties.
