Active pharmaceutical ingredient (API) comprising cannabinoids for use in the treatment of cancer
The present invention relates to an active pharmaceutical ingredient (API) which comprises or consists essentially of cannabidiol (CBD) and one other cannabinoid selected from cannabigerol (CBG), cannabigerolic acid (CBGA), cannabidiolic acid (CBDA), and tetrahydrocannabivarin (THCV) for use as a medicament, and more particularly, for use in the treatment of cancer. These combinations have shown themselves to be synergistic in treating one or more of: breast cancer; liver cancer; lung cancer; pancreatic cancer; melanoma; ovarian cancer; gastric cancer; renal cancer or bladder cancer. Two particularly favored API combinations are: cannabidiol (CBD) and cannabigerol (CBG); and cannabidiolic (CBD) and tetrahydrocannabivarin (THCV).
1. A method of treating melanoma comprising administering to a patient in need thereof an active pharmaceutical ingredient (API) comprising or consisting essentially of cannabidiol (CBD) and cannabigerol (CBG).
2. The method as claimed in claim 1 , wherein the CBD and CBG are present in a ratio of from 7.5:1 to 1:7.5 (CBD:CBG).
3. The method as claimed in claim 2 , wherein the CBD and CBG are present in a ratio of 7.5:1 to 2.5:1 (CBD:CBG).
4. The method as claimed in claim 2 , wherein the CBD and CBG are present in a ratio of about 5:1 (CBD:CBG).
5. The method as claimed in claim 2 , wherein the CBD and CBG are present in a ratio of 2:1 to 1:2 (CBD:CBG).
6. The method as claimed in claim 2 , wherein the CBD and CBG are present in a ratio of about 1:1 (CBD:CBG).
7. The method as claimed in claim 1 , wherein a dose of the API administered to the subject is between 1 and 1000 mg/kg day.
8. The method as claimed in claim 1 , wherein the API is administered as a pharmaceutical formulation comprising the API and one or more excipients.
9. The method as claimed in claim 8 , wherein the CBD is formulated for administration separately, sequentially or simultaneously with the CBG or the CBD and CBG are provided in a single dosage form.
