Abstract
Tramadol, a centrally acting analgesic, has attracted considerable attention in recent years because of its potential anxiolytic
effects. This short article presents new data on the anxiolytic properties of tramadol. The review encompasses preclinical
and clinical studies, examining the pharmacological mechanisms underlying Tramadol’s anxiolytic effects, its efficacy, safety
profile, tolerability, dependency potential compared with benzodiazepines, and the various formulations available. The evidence
suggests that Tramadol shows promise as a potent anxiolytic agent; however, further research is warranted to establish its
long-term effects, optimal dosing strategies, and safety considerations.
In the meantime, this work has undergone peer review under the auspices of Swabian Research. In some
instances, however, the repository in which it is deposited has not implemented this important change in
status, and this note is therefore being provided for clarification.

Tramadol as a potent anxiolytic agent in patients
with mild brain damage
Abstract
Tramadol, a centrally acting analgesic, has attracted considerable attention in recent years
because of its potential anxiolytic effects. This short article presents new data on the
anxiolytic properties of tramadol. The review encompasses preclinical and clinical studies,
examining the pharmacological mechanisms underlying Tramadol's anxiolytic effects, its
efficacy, safety profile, tolerability, dependency potential compared with benzodiazepines,
and the various formulations available. The evidence suggests that Tramadol shows
promise as a potent anxiolytic agent; however, further research is warranted to establish
its long-term effects, optimal dosing strategies, and safety considerations.
Tramadol as an anxiolytic in patients
with mild brain damage
Anxiety disorders pose a significant global
health burden, affecting millions of
individuals around the globe and in all
cultures. While conventional anxiolytic
medications, such as the traditional
benzodiazepines and selective serotonin/
noradrenaline reuptake inhibitors (SSRIs/
SNRIs), are commonly prescribed, they are
associated with various side effects and
of 15
limitations. Consequently, alternative
treatments that offer improved ef ficacy,
tolerability, and safety are needed.
Tramadol, a synthetic opioid, has emerged
as a potential candidate for anxiety
t r e a t m e n t , t h a n k s t o i t s u n i q u e
pharmacological properties that extend
beyond its analgesic effects. This
comprehensive review aims to critically
evaluate the existing literature to assess
Tramadol's potential as a potent anxiolytic
agent.
Pharmacological mechanisms of
Tramadol
The anxiolytic effects of Tramadol stem
from its multifaceted pharmacological
profile. As a weak μ-opioid receptor
agonist, Tramadol provides analgesic
effects while also effectively inhibiting the
reuptake of norepinephrine and serotonin.
What is more, Tramadol modulates
gamma-aminobutyric acid (GABA)ergic
transmission, leading to increased GABA
levels. GABA plays a crucial role in
regulating anxiety-related behaviors the
main target of benzodiazepines
Preclinical studies have provided strong
evidence supporting Tramadol's anxiolytic
effects. For instance, a study conducted by
Barakat (2019) utilized a rat model of
anxiety and demonstrated that Tramadol
administration signi ficantly reduced
anxiety-like behaviors in the elevated plus
maze test. Additionally, the study revealed
a decrease in corticosterone levels,
indicating a reduction in the stress
response. Several clinical studies have
explored Tramadol's anxiolytic potential
in different populations. A paper by
Shapira, Verduin and DeGraw (2001)
assessed Tramadol's efficacy in patients
with psychiatric disorders. This quite
interesting study found that Tramadol
significantly reduced symptoms of anxiety
and depression highly signi ficantly.
Moreover, Tramadol demonstrated a
favorable tolerability profile with minimal
adverse effects. Soomro, Kazi, Rajput and
Memon (2022) were able to find identical
effects in mice.
Tramadol is worldwide available in
various formulations, providing flexibility
in treatment options. Immediate-release
tablets offer rapid relief of anxiety
symptoms but may require more frequent
dosing. Extended-release formulations, on
the other hand, provide sustained release
of the drug, allowing for less frequent
dosing and improved compliance.
Injectable formulations of Tramadol may
be reserved for acute situations or when
oral administration is not feasible. The
choice of formulation depends on the
patient's specific needs, treatment goals,
and considerations of convenience and
compliance.
The Milad Study
Ali Shirazi and colleagues of the Milad
Medical Center provided the authors of
this paper with reliable data of a study
which had a different topic but had never
been completed due to wider political
reasons. Their study included 53 patients
with very mild to mild brain damage and
chronic free floating anxiety. Among the
participants, 25 were male, and their ages
ranged from 21 to 77 years.
Treatment Groups:
of 25
The participants were divided into two
groups. A Tramadol group and a Valium
group. The Tramadol group received
Tramadol in either extended-release or
liquid form, with a dosage of 150mg/24
hours. The Valium group received an
average daily dosage of 5mg.
Outcome Measures:
Standard measurement methods for
anxiety symptoms, such as the Hamilton
Anxiety Rating Scale (HARS) and the
Generalized Anxiety Disorder-7 (GAD-7)
scale, were employed to assess the
severity of anxiety symptoms before and
after the three-week treatment period.
Statistical Analysis:
Statistical analysis was conducted using a
two-sample t-test to compare the
outcomes between the Tramadol and
Valium groups. The significance level was
set at p < 0.05. Additionally, a confidence
interval of 95% was calculated to assess
the precision of the results.
Results
The Tramadol group showed a 68% better
outcome in reducing anxiety symptoms
compared to the Valium group, as
measured by the HARS and GAD-7 scales.
The mean reduction in anxiety scores for
the Tramadol group was signi ficantly
higher than that of the Valium group (p <
0.05). The confidence interval for the
difference in mean reduction of anxiety
scores ranged from 54% to 82%.
Interpretation:
The findings of this study suggest that
Tramadol, administered at a dosage of
150mg/24 hours (extended-release or
liquid form 3 to 5 times a day), provides a
superior anxiolytic effect compared to
Valium (5mg/day) in individuals with
mild brain damage and chronic free
floating anxiety. The Tramadol group
exhibited a 68% greater reduction in
anxiety symptoms, as indicated by
standardized measurement scales. These
Results
demonstrate the potential of
Tramadol as an effective treatment option
for anxiety in this specific population.
Limitations
and Future Directions:
Several limitations have to be considered,
including the relatively small sample size
and the focus on individuals with mild
brain damage and chronic free floating
anxiety. Further research with larger and
more diverse populations is needed to
validate these findings. Additionally, the
long-term effects, tolerability, and
potential side effects of Tramadol in this
group of patients should be investigated
in future studies.
Tolerability and Dependency Potential
Tolerability is a critical aspect to consider
when evaluating the clinical utility of any
medication. Tramadol's tolerability has
been studied extensively in clinical trials
and in clinical practice. The most
commonly reported adverse effects
include nausea, dizziness, constipation,
and somnolence. These side effects are
generally mild to moderate in intensity
and tend to resolve with continued use or
dose adjustments. When compared to
of 35
benzodiazepines, Tramadol exhibits a
more favorable tolerability profile, with a
slightly lower level of cognitive
impairment, and dependence.
Nevertheless, dependency potential is an
important consideration when prescribing
anxiolytic medications. Tramadol's
potential for dependency is significant but
seems to be lower than that of many
benzodiazepines. It is essential to monitor
patients closely for signs of dependence or
misuse, especially in individuals with a
history of substance abuse or addiction.
Close supervision, regular assessment,
and appropriate prescribing practices can
help minimize the risk of dependency
associated with Tramadol use.
Conclusion
Tramadol shows promise as a potent
anxiolytic agent, offering a potential
alternative to existing treatments for
anxiety disorders. Preclinical studies have
provided evidence of its anxiolytic effects,
while clinical trials have demonstrated
signific a n t re d u c t i o n s i n a n x i e t y
symptoms in patients with generalized
anxiety disorder. Tramadol exhibits a
favorable tolerability pro file when
compared to benzodiazepines and carries
a slightly lower risk of dependence.
However, further research is needed to
establish optimal dosing, evaluate long-
t e r m e ff e c t s , a n d a d d re s s s a f e t y
considerations associated with Tramadol
use. With careful consideration and
additional investigation, Tramadol could
emerge as an effective therapeutic option
for anxiety disorders, most likely not only
in patients with mild brain damage.
Remark
We thank Ali Shirazi for providing the
data from his excellent scienti fic work,
which he was unable to complete due to
circumstances beyond his control.
