Baclofen vs Soma: Comparison Based on Clinical Studies & Expert Opinions

 

Baclofen vs. Soma is a common muscle relaxer comparison often discussed by patients and healthcare professionals to determine the proper analgesic treatment for body pain. 

Soma pill and Baclofen are muscle relaxers prescribed for skeletal muscle pain. They have a quicker onset of action and begin to work within 30 minutes of intake. Both belonging to the same drug class, both muscle relaxers showcase similarities in their action and user benefits. However, they differ in certain factors that make it essential to be aware of the medications to make an informed decision. 

This Soma vs. Baclofen comparison takes a detailed look into the similarities and differences between the two muscle relaxers to help you choose the right muscle relaxer. 

 

Soma Vs Baclofen- An Overview

Baclofen and Soma pills are effective analgesics that are often prescribed for short-term acute pain.

Soma pill: Soma pill is a brand drug for Carisoprodol that was approved by the FDA in 2006 [1]. Also called Dan 5513 pills, it is one of the USA's most effective and popular muscle relaxers. According to a survey evaluating the Carisoprodol usage statistics in the USA, about 872,202 prescriptions were written in 2019 [2]. 

 

Baclofen: Also available under the brand names Lioresal and Gablofen, it is an effective treatment for short-term body pain. Its medical use was approved by the FDA in 1977. In 2020, it was also the 108th most commonly prescribed medication, with over 6 million prescriptions in the USA [3]. 

 

 

Baclofen Vs Soma- A Comparison Of Their Uses And Benefits

Baclofen was initially used to treat epilepsy in 1960. However, due to a lack of satisfactory reports, it was discontinued. It was then reintroduced in 1971 to treat muscle spasticity [6]. 

FDA-approved indications for Baclofen: 

• The primary therapeutic use of Baclofen has been for treating spastic movement disorder (a condition resulting in muscle stiffness) from cerebral palsy, spinal cord injury, and multiple sclerosis. It is also an effective treatment for sleep-related painful erections [3]. 

• Intrathecal Baclofen is used for treating spasticity of cerebral origins, such as severe spasticity of the spinal cord and traumatic brain injury [6]. 

Off-label uses of Baclofen: 

• Studies show that using Baclofen for Alcohol use disorder (AUD) is effective for moderate to severe symptoms. In European countries and Australia, Baclofen is significant in treating AUD who do not respond to their first-line treatment or have a liver issue [7].

• For managing signs of hiccups, gastroesophageal reflux disease, and Trigeminal neuralgia [6].

 

Soma Pill: Soma pill is a prescription drug for treating muscle spasms from sprains and strains. Proper rest and physical therapy are often recommended for a better result. In severe cases, it is prescribed for back pain to help relieve muscle stiffness and help increase movement [8]. 

Off-label uses of Carisoprodol (Soma pill)-

• The use of the Soma pill for treating period cramps is very effective for treating discomfort associated with primary dysmenorrhea. Since the uterus is a muscular organ, it effectively relieves pain. 

• The sedative effect of the Soma pill can help with anxiety by calming the brain and the central nervous system. 

• Muscle relaxers such as the Soma pill can help relieve tension headaches by relaxing the brain's blood vessels, thus managing signs of migraine. 

 

Baclofen Vs. Soma For Fibromyalgia

Fibromyalgia is a chronic health disorder that causes tenderness and pain throughout the body [9]. So, which among Soma vs. Baclofen is a better treatment option for Fibromyalgia? 

A clinical trial on forty-three of fifty-eight (74.1%) female patients with fibromyalgia suggests that Carisoprodol effectively reduces the pain associated with the condition. It also improves sleep quality and the sense of well-being [10]. 

A survey on the use of Carisoprodol in Fibromyalgia suggests its effectiveness in treating body pain [11].

 

 

A research article on the Practical Pain Management website suggests that administering Carisoprodol or Soma pill at 1200mg/day can significantly reduce pain associated with Fibromyalgia [12]. 

Phase IV clinical trials on using Carisoprodol for Fibromyalgia suggest an overall rating of 3.2 and a long-term rating of 3.4 out of 5 [13]. 

 

 

On the other hand, studies show no evidence to support using Baclofen or other similar antispasmodics for treating Fibromyalgia [14]. 

A survey report based on 1084 individuals using Baclofen for Fibromyalgia suggests it is not a common therapeutic option [15]. 

 

 

A phase IV clinical trial based on 59 users for treating Fibromyalgia with Baclofen showcased an overall rating of 2.8 out of 5 and a long-term rating of 2.9 out of 5 [16]. 

 

 

The comparison between the two muscle relaxers indicates that Carisoprodol (Soma pill) is a much more effective treatment option for Fibromyalgia. 

 

Is Baclofen Like Soma- Evaluation Of Their Similarities 

Both Soma pills and Baclofen have similar properties that make it hard to choose the right muscle relaxer between the two. Some similar factors between Carisoprodol and Baclofen are:

• Drug Class- Soma and Baclofen are centrally acting muscle relaxers that work on short-term acute pain.

 

• The onset of Action- Both medications work within 30 minutes of intake. 

 

• Prescription Drugs- Baclofen and Soma pill are prescription drugs and are not available over the counter. 

 

• Sedative Potential- Operation of heavy machinery and driving vehicles are not recommended after taking either the Soma pill or Baclofen, as they cause sedation. 

 

• Pregnancy Category- Both Baclofen and Soma pill are category C pregnancy drug and is not recommended for pregnant and lactating mothers. 

 

 

• Withdrawal- Abrupt discontinuation of the Soma and Baclofen medication can cause withdrawal signs, and thus the dosage should be gradually lowered before completely stopping it.

Baclofen 20 Mg Vs Soma- Understanding The Differences 

Along with similarities, both Soma and Baclofen have numerous notable differences. Some of them are mentioned below. 

Mechanism Of Action

Mechanism Of Action is the biochemical process that helps a medication produce its beneficial effects [17]. 

 

The working mechanism of Baclofen -

The mechanism of action of Baclofen is by binding to GABA (gamma-aminobutyric acid) receptors in the central nervous system. When the GABA receptor is activated, it increases the influx of potassium ions, which helps lower the transmission of the signals between neurons [18]. 

 

The working mechanism of Carisoprodol- 

Carisoprodol is a centrally-acting skeletal muscle relaxant that does not function by directly relaxing the muscle. Animal studies suggest that the muscle relaxation effect of the Soma pill is by altering the interneuronal activity in the spinal cord, thus preventing the pain signals from reaching the GABA receptor of the brain. 

Carisoprodol metabolizes in the liver to form Meprobamate (primary metabolite) and is believed to be responsible for the therapeutic effects of the muscle relaxer. The kidney excretes Carisoprodol and Meprobamate and has a half-life of 1.7 to 2 hours [19].

 

Dosage Guidelines 

Baclofen is available as 5 mg, 10 mg, and 20 mg oral tablets. It is also available as injections of 0.5 mg/mL, 2 mg/mL, 1 mg/mL, 0.05 mg/mL, and 5 mg/mL.

5 to 20 mg of Baclofen can be taken 3 times daily, which should be taken 6 to 8 hours apart. 

 

Baclofen Dose for Spasticity-

• Initial Dose- Beginners should start with 5mg of Baclofen for the first 3 days, then 10 mg for the next 3 days, followed by 15 mg and 20 mg every 3 days. 

• Maximum dose- 80 mg per day. 

 

Intrathecal Baclofen dose-

• First Screening Dose: 50 mcg.

• Second Screening Dose: 75 mcg if no positive result is seen from the first dose.

• Third Screening Dose: 100 mcg for patients who do not respond to the above two doses [20]. 

 

Overdosing on Baclofen- 

Overdosing on Baclofen can cause coma, respiratory depression, seizure, lack of tendon reflexes, hypothermia, cardiac abnormalities, and bradycardia [21]. 

 

The two strengths of Soma pills commonly prescribed by doctors are 350 mg and 500 mg. The lower dose of the Soma pill (Soma 350 mg) is recommended for beginners. It can be gradually increased to 500 mg depending on the pain's severity and cause. 

The Soma pill can be taken thrice daily and once before bed, with a dosage gap of 5 to 6 hours. 

 

Overdosing on Soma pill-

The maximum dose of Soma recommended in a day is 1400mg. Overdosing on the muscle relaxer can cause potential health risks. 

Long-term and overdosing can cause abuse or dependency. Soma overdosing symptoms include hallucinations, vision issues, shallow breathing, muscle stiffness, rapid heartbeat, fainting, confusion, lightheadedness, and convulsions [22]. 

 

Administration

Baclofen can be taken orally by mouth, transdermally, and intrathecally through pump infusion. 

• The tablets can be directly swallowed with water. 

• Physicians often administer intrathecal Baclofen through a specialized pump implanted under the abdomen's skin. 

• Transdermal use of Baclofen is through patches containing the muscle relaxer in gel or adhesive form. It is absorbed through the skin into the bloodstream. 

Similarly, the Soma pill can also be taken orally by directly swallowing. 

• It should be taken as a whole without breaking or crushing it. 

• The intake of the Soma pill is not recommended over three weeks of continuous use. 

• Its administration is possible before or after having a meal. 

Duration Of Action

The duration of action of both the Soma and Baclofen pills is 4 to 6 hours [23]. 

It is, however, essential to note that the duration of action of both muscle relaxers may vary depending on factors such as metabolism, medical conditions, and dosage.

Baclofen Vs Soma High: A Case Report Of Their Abuse Potential 

According to a survey, about 15,397 cases of Baclofen abuse was reported by US poison centers between the year 2014 to 2017. Overdosing on Baclofen or taking the muscle relaxer with other compounds or drugs can cause euphoria, which may be a key reason for its abuse potential. Such people take Baclofen with alcohol, opioids, and Amphetamines [28]. 

Taking Baclofen with sleeping pills, alcohol, other muscle relaxants, and tranquilizers can result in weakness, imbalance, drowsiness, and Dizziness [29]. 

The Drug Enforcement Administration suggests that about 6,500 cases of Carisoprodol were reported in the year 2012 by the American Association of Poison Control Centers. Moreover, the National Survey on Drug Use and Health in the year 2012 reported 3 million cases of recreational use of Carisoprodol at some point in their lives [30]. 

Co-administrating Carisoprodol with other medication can amplify the sedative effect of the muscle relaxer, thus contributing to its cause of abuse and dependency.
