Spasticity, such as painful muscle spasms, is a big contributor to the illness burden of Numerous Sclerosis (MS). But traditional medicines are not often powerful at treating this symptom. A new overview published in the Journal of Central Nervous Program Illness appears at the effectiveness of a 1:1 THC and CBD mouth spray for treating spasticity in sufferers with MS.

The Impacts of Numerous Sclerosis

MS is a illness exactly where the immune program attacks and degrades the protective covering of nerve cells. This tends to make it tough for the brain to send signals to the rest of the physique. As a outcome, lots of of the body’s standard functions are compromised.

1 of the most debilitating symptoms of MS is spasticity. Spasticity refers to muscle stiffness and involuntary spasms in the limbs, most regularly the legs. These symptoms can be extremely painful and interfere with day to day activities. It is also one particular of the most widespread symptoms, occurring in about 80% of MS sufferers.

Spasticity does not take place in isolation. Aside from discomfort, the spasms can lead to a host of secondary symptoms such as disrupted sleep and bladder difficulties. The loss of mobility brought about by muscle spasms also has a considerable influence on patient high-quality of life.

Hence, powerful management of spasticity is essential for treating MS sufferers. Existing therapies solutions include things like a mixture of physiotherapy and anti-spasticity medicines such as:

  • Baclofen
  • Dantrolene
  • Tizanidine
  • Gabapentin

Having said that, not all sufferers respond to these medicines. Lots of also endure from adverse side effects, particularly with prolonged use and higher dosages.

Sativex: A Cannabis-Primarily based Remedy for MS

For sufferers who do not respond or have undesirable reactions to classic anti-spasticity medicines, there’s yet another choice. Researchers have shown that cannabis can be powerful for treating MS symptoms such as spasticity.

In some nations, there’s currently an authorized cannabis-primarily based choice named Sativex. Sativex is a mouth spray derived from the cannabis sativa plant. It includes a 1:1 ratio of THC (tetrahydrocannabinol) to CBD(cannabidiol).

A variety of government agencies about the planet such as in Canada and the European Union have authorized Sativex as an add-on therapy. This indicates that medical doctors can prescribe Sativex to adults with MS who haven’t responded to other anti-spasticity medicines and who respond properly to Sativex in the course of an initial trial period.

THC  and CBD are the two most prominent cannabinoid compounds in the cannabis plant. THC acts on the cannabinoid receptors CB1 and CB2. Researchers think that THC acts as a muscle relaxer and improves spasticity. Customers typically believe about THC as the psychoactive compound. CBD can complement the effects of THC. And when taken with each other, CBD reduces the psychoactive effects of THC such as anxiousness. Researchers confirmed these obtaining in numerous randomized controlled trials (RCTs) and long-term research.

Confirming THC and CBD Effects with True Globe Proof

Researchers and medical doctors contemplate RCTs the gold common when it comes to clinical proof. That is due to the fact they straight test a hypothesis and take lots of measures to cut down bias.

But it is a double-edged sword. For the reason that RCTs are so tightly controlled, they can not often be generalized to every day clinical practice. For this purpose, true-planet information delivers a excellent complement to RCTs. This can include things like information from healthcare record testimonials, case research, databases, potential or retrospective patient information collections, or observational cohort research.

A group of researchers from the University Hospital Dresden in Germany set out to discover a lot more true-planet information for Sativex. They wanted to confirm the outcomes of the Sativex RCTs for MS spasticity. They scoured the investigation literature to discover higher-high-quality, true-planet proof for the advantages and security of the THC and CBD spray for treating MS spasticity.

The researchers identified 14 publications that match their criteria for higher-high-quality, observational research. Individuals in these research took the THC/CBD spray according to the authorized label suggestions. In all of the research, the researchers applied a quantitative and validated system to appear at adjustments in spasticity symptoms.

In most of the research, the sufferers also continued the use of their other anti-spasticity medicines. Having said that, some sufferers only applied Sativex spray due to the fact they couldn’t tolerate other medicines.

The Outcomes

So how powerful was Sativex below true-planet circumstances? The researchers identified a consensus that the 1:1 THC:CBD spray, Sativex, considerably enhanced patient spasticity symptoms.

For instance, in the biggest study integrated in the overview, researchers saw an initial good response in 70% of sufferers. This is related to the outcome for sufferers who participated in Sativex RCTs. In the RCT research, initial response prices varied among 42% and 83%.

The observational research also confirmed that Sativex improves secondary symptoms related with spasticity. In one particular study, sufferers skilled considerable decreases in sleep disturbances, discomfort, muscle stiffness, and restricted mobility just after employing the THC/CBD spray.

Moreover, some research showed considerable increases in high-quality of life for sufferers employing Sativex. And related to the RCTs, sufferers reported pretty couple of adverse side effects. Dizziness, drowsiness, and fatigue had been the most generally reported side effects.


Spasticity is the most prominent and debilitating symptom for sufferers suffering from MS. This study clearly shows that the true-planet information is in agreement with the controlled clinical trials. A 1:1 combo of THC and CBD is an powerful and properly tolerated therapeutic choice for MS sufferers who do not respond properly to traditional anti-spasticity drugs.
