Muscle relaxants
Muscle relaxant is a collective term for a group of different
kinds of drugs, which all have some form of sedative effect
on the body. Despite what their name may imply, muscle relaxants
when referred to in the sense of pain relievers do not usually
act on the muscles at all, but on the central nervous system,
causing a state which might best be summarized as ‘total body
relaxation’
Muscle relaxants are usually prescribed for the relief of
mild to moderate pain, especially muscular aches and pains,
back pain and muscle spasms. Drugs which currently fall under
the broad umbrella of muscle relaxants include Valium, Soma
and Flexeril.
Valium, or diazapam, is usually prescribed as a short-course
treatment lasting a week or two and the standard dose is between
five and ten milligrams ever six hours or as needed for the
relief of pain, particularly back pain and pain associated
with muscle spasms.
Valium is restricted to short courses because it is potentially
habit-forming, and can have detrimental effects on a person’s
psychological health and sleeping patterns, making it hard
for people who come off Valium to re-establish a healthy sleep
schedule.
Valium is also quite a potent depressant, and might therefore
run the risk of worsening depression in patients who are already
experiencing it to some degree because of the pain and discomfort
caused by their conditions.
Soma, or carisoprodol, is also prescribed in short courses,
and is taken in a similar manner to Valium for the relief
of pain, particularly pain related to muscle spams. Soma is
potentially habit-forming, particularly when combined with
alcohol or other recreational drugs.
Flexeril is prescribed to treat muscular pain when a long
term solution is required and neither Valium or Soma would
be practical solutions. It works in a similar way to some
antidepressants, though it is not one itself. Flexeril is
usually taken in a dosage of around ten milligrams every 6
hours or as needed to relieve lower back pain and pain related
to muscle spasms, and can also be effective in helping people
with various types of pain to get to sleep for a reasonable
period of time. Flexeril should not be used in conjunction
with any other sedatives, and may be inappropriate for some
patients as it has the potential to impair physical and mental
function.
Antispasmodic drugs can also be used to treat muscular pain,
and these drugs can be broadly categorized into benzodiazepines
and non-benzodiazepines.
Benzodiazepines are also known as benzodiazepine receptor
agonists, or BzRAs. They are very commonly prescribed to treat
conditions where some form os sedation is required, such as
those that require pain relief, or sleep disorders.
They work by non-selectively targeting particular receptor
sights in the brain which modulate the effect of GABA, or
gammaaminobutyric acid, which is a neurotransmitter. Popular
benzodiazepines include alprazolam, temazepam and flunitrazepam,
or to give them their commercial names, Xanax, Restoril and
Rohypnol.
Benzodiazepines can also be used in the treatment of anxiety,
and lorazapam and diazepam are sometimes given intravenously
to treat patients who experience panic attacks. Because of
their strong sedative effects, benzodiazepines should not
be used by people who are actively doing anything that may
become dangerous should their senses become impaired, such
as driving. For this reason though, they make excellent treatments
for insomina.
Sedatives used for this purpose should be used on a short-term
basis however, since dependance and tolerance may occur.
Benzodiazepines are also useful to sedate patients prior
to surgery, especially those who are experiencing anxiety.
They can also cause amnesia as a possible side-effect, which
can actually be helpful for some patients, who would rather
not remember their surgical experience anyway. The particular
choice of sedative in dental surgery is Lorazepam. Alternatively
nitrous oxide may be used, which is faster acting, yet shorter
lasting.
Muscle relaxants can be employed in the treatment of alcoholism,
as they can go a long way towards lessening the symptoms if
alcohol withdrawal. Potentially fatal forms of delirium can
be ended or even prevented by sedatives, most often Librium
or Valium.
Mania, a severe psychiatric disorder, can also be treated
using muscle relaxants. Manic patients experience states of
acute elevated moods, which can be extremely dangerous for
themselves and those around them.
Sedatives, usually benzodiazepines, can be useful to take
the edge off the condition in the short-term, until some more
appropriate neuroleptic or dosage of Lithium can take effect.
Clonazepam and lorazepam are both commonly used for just this
purpose.
Newer muscle relaxants are generally in the form of non-benzodiazepines,
including zolpidem, zaleplon, eszopliclone and ramelteon,
whose trade names are Ambien, Sonata, Lunesta and Rozerem
respectively. These drugs target specific receptor sights
in the brain, as opposed to benzodiazepines which target receptor
sights more generally. This means that they are shorter lasting,
with fewer side-effects than their older generational cousins.
Muscle relaxants will usually be prescribed along with recommended
lifestyle changes which may involve diet, exercise, rest,
or physical therapy. They are typically short-term solutions
for short-term problems, and should not be considered permanent
solutions due to their possible side-effects and addictive
qualities.
Since different people react differently to different types
of drugs, it may be the case that several different muscle
relaxants may need to be tried before a patient finds one
that is effective for them. It is also important to always
take medical advice and follow manufacturers guidance when
starting a course of muscle relaxants.
