Despite initial control of seizures on monotherapy, events returned in prompting adjustment of anti-seizure medications and eventual consideration of epilepsy surgery. Following video EEG monitoring, he was determined to be a poor surgical candidate due to non-localized seizure onset.
Additionally, the need for anticoagulation due to mechanical valve limited more invasive testing for localization of seizure focus as well as posed a challenge for completion of any surgical resection. He was also taking warfarin 7. Per study protocol www. Warfarin dosage adjustments were made by primary care physician in effort to maintain an INR within his therapeutic range.
The patient was followed clinically without bleeding complications. Despite the emergence of novel oral anticoagulants, warfarin continues to be the most commonly used oral anticoagulant worldwide . A potent inhibitor of vitamin K epoxide reductase complex, warfarin functions by disrupting the production of vitamin-K-dependent clotting factors . The drug is comprised of R and S stereoisomers with S-warfarin being the more active of the two.
Warfarin is metabolized via the CYP hepatic enzyme complex and cleared through the renal system, however each stereoisomer is metabolized differently. Resultantly, factors that impact the CYP2C9 enzyme genetic polymorphisms, other medications, etc.
Due to its narrow therapeutic index and variability of dosing requirements amongst individuals, frequent monitoring of the INR is required to both achieve and maintain appropriate anticoagulant effects on the blood. Drugs that compete as substrates for these cytochromes or inhibit their activity may increase warfarin plasma concentrations and INR, potentially increasing the risk of bleeding. Conversely, drugs which induce these metabolic pathways may decrease warfarin plasma concentrations and INR, potentially leading to reduced efficacy.
The metabolism of CBD is also by way of the hepatic P enzyme system. To date there are seven major isoforms identified that contribute to this process: Five of the seven isoforms are also involved with metabolism of warfarin, including CYP2C9, which is the dominant enzyme for S-warfarin, and CYP3A4, which is the dominant enzyme for R-warfarin  , .
In addition to competing for enzymes in same metabolic pathway as warfarin, CBD has been demonstrated to act as a potent competitive inhibitor of all seven of its own CYP enzymes and as such could further impair the degradation of warfarin  , . It is this combination of factors that presumably constitutes the observed rise in INR values with concomitant warfarin and CBD administration.
This finding suggests an interaction between warfarin and cannabidiol, underscoring the importance of monitoring appropriate laboratory work in patients receiving concomitant cannabis products and other pharmaceuticals, particularly those metabolized by the cytochrome P enzyme system. In patients taking warfarin, INR monitoring is suggested during initiation and up-titration of cannabinoids.
National Center for Biotechnology Information , U. Epilepsy Behav Case Rep. Small doses of cannabis tend to stimulate; large doses sedate. Too much THC , while not lethal, can amplify anxiety and mood disorders. CBD has no known adverse side effects, but an excessive amount of CBD could be less effective therapeutically than a moderate dose. Look for products with clear labels showing the quantity and ratio of CBD and THC per dose, a manufacturing date, and a batch number for quality control.
Select products with quality ingredients: No corn syrup, transfats, GMO s, artificial additives, thinning agents or preservatives. Medical marijuana should be lab tested for consistency and verified as being free of mold, bacteria, pesticides, solvent residues, and other contaminants.
It's best to avoid products extracted with toxic solvents like butane or other hydrocarbons. Many cannabis vape oil products include a thinning agent to dilute the cannabis oil. Beware of vape pen oil that contains propylene glycol. When overheated, this chemical additive produces a carcinogen byproduct.
If vaping, be sure to find a product with pure cannabis oil and no diluting agents. There's no single ratio that's right for everyone. A person's sensitivity to THC is a key factor in finding the right ratio and dosage. Many people like the cannabis high. Others find THC unpleasant. THC so you can adjust or eliminate psychoactive effects as you prefer. Some patterns are beginning to emerge.
For anxiety, depression, spasms, psychosis, and seizure disorders, some people report they do best with little THC. For cancer, autism, and other diseases, some patients say they benefit more from a balanced ratio of CBD and THC like the 4: Extensive clinical trials conducted outside the United States have shown that a 1: THC ratio can be effective for neuropathic pain.
Some people use cannabis products with different CBD: Medical marijuana and CBD , in particular, are very safe, but patients taking other medications should check with their doctor about drug interactions. At sufficient dosages, CBD will temporarily deactivate cytochrome P enzymes, thereby altering how we metabolize a wide range of compounds. Cytochrome P enzymes metabolize more than 60 percent of pharmaceuticals. CBD is a more potent inhibitor of cytochrome P than the grapefruit compound Bergapten, so ask your doctor if grapefruit interacts with your medication.
If grapefruit does, then CBD probably does, too.
CBD Oil Dosage: General Tips to Assess How Much CBD to Take
CBD inhibits the cytochrome P enzyme, which is involved in metabolizing advice patients not to eat grapefruit shortly before or after taking a medication. What's more, medications like benzodiazepines can be addictive Summary Using CBD has been shown to reduce anxiety and Researchers believe that CBD's ability to act on the endocannabinoid system and other brain. Get the facts on CBD oil, a natural product that may ease your anxiety and As more and more states legalize the use of marijuana, a product known as CBD oil has When used safely and carefully, many alternative treatments can make a look at findings from recent studies on several other possible benefits of CBD oil: .
