Sativex, a cannabinoid medicine combining THC and CBD, effectively treats pain and multiple sclerosis symptoms. It is well-tolerated and self-administered, with minimal side effects.
Area of Science:
- Pharmacology
- Neuroscience
- Cannabinoid Research
Background:
- Cannabis sativa L. compounds (cannabinoids) show therapeutic potential for pain and spasticity.
- Patients use cannabis for debilitating symptoms despite legal and social challenges.
- Existing treatments may have limitations, necessitating alternative therapies.
Purpose of the Study:
- To evaluate the efficacy and tolerability of Sativex, a novel oromucosal cannabinoid spray.
- To assess Sativex's potential in managing various pain conditions and multiple sclerosis symptoms.
- To determine if Sativex minimizes psychotropic side effects associated with cannabinoids.
Main Methods:
- Development of Sativex, a combined cannabinoid oromucosal pump spray containing THC and CBD.
- Administration and titration of Sativex in healthy volunteers and patient cohorts.
- Clinical assessment of Sativex efficacy in patients with intractable pain, rheumatoid arthritis, and multiple sclerosis.
Main Results:
- Sativex demonstrated good tolerability and successful self-administration and self-titration.
- Efficacy was observed in patients with chronic neuropathic pain, cancer pain, rheumatoid arthritis, and multiple sclerosis (spasticity, central pain, bladder issues).
- No significant intoxication-like symptoms, tolerance, or withdrawal syndromes were reported.
Conclusions:
- Sativex is a well-tolerated and effective treatment option for various pain conditions and multiple sclerosis symptoms.
- The oromucosal spray delivery of THC and CBD offers therapeutic benefits with minimized psychotropic effects.
- Further research supports the clinical utility of cannabinoid-based medicines in managing chronic conditions.

Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
