Q

The DEA can reclassify a drug schedule when the perceived risk of abuse or dependence associated with a drug changes. When a scheduling change occurs, a pharmacy must complete an:

A

inventory of the drug on the date the change becomes effective. After the initial inventory, subsequent inventories are conducted according to the requirements of the new schedule.

17
Q

States can choose to classify drugs into stricter scheduling categories than the DEA. When state and federal pharmacy law differ, stricter law should be followed. For example, Fioricet is not federally classified as a controlled substance, but California classifies Fioricet as…

A

schedule III.

18
Q

Some drugs (eg, barbiturates, codeine, dronabinol) may have varying schedules based on the formulation.

Barbiturates:

A
  • Schedule II: single-entity oral formulations of amobarbital, pentobarbital, and secobarbital
  • Schedule III:
  • amobarbital, pentobarbital, secobarbital formulated as a suppository
  • Amobarbital, pentobarbital, secobarbital in combination with a non-controlled substance
  • Butabarbital
  • Butalbital-containing products
  • Schedule IV: phenobarbital
19
Q

Codeine Schedules:

A
  • Schedule II: single-entity products
  • Schedule III: combination tablets/capsules that contain codeine [eg, acetaminophen 300 mg/codeine 30 mg (Tylenol #3)]
  • Schedule V: combination cough syrups that contain codeine (eg, promethazine/phenylephrine HCl/codeine syrup
20
Q

Dronabinol Schedules:

A
  • Schedule II: oral solution (Syndros), which is 50% alcohol
  • Schedule III: oral capsules (Marinol)
21
Q

Federal law designates marijuana as a schedule I controlled substance. The ratio of THC:CBD contributes…

A

to a product’s therapeutic efficacy and psychoactive effect.

22
Q

Epidiolex (cannabidiol), the first FDA-approved CBD-derived product, is indicated for seizures associated with several disorders: Lennox-Gastaut syndrome, Dravet syndrome, and tuberous sclerosis complex. Initially, the DEA approved Epidiolex in a new classification of schedule V that would include FDA-approved CBD drugs containing no more than 0.1% (w/w) residual THC. However, in 2020, the DEA:

A

descheduled Epidiolex, so it is now considered a non-controlled drug according to federal and California law.

23
Q

There are also 2 FDA-approved cannabis-related drugs (ie. not cannabis-derived, like Epidolex):

A
  • Dronabinol: a synthetic delta-9-tetrahydrocannabinol (synthetic THC) approved for AIDS-associated anorexia and chemotherapy-induced nausea and vomiting (CINV). It is available as an oral capsule (Marinol, schedule III) and an alcohol-containing oral solution (Syndros, schedule II).
  • Nabilone (Cesamet*, schedule II): a synthetic cannabinoid with a chemical structure similar to THC that is indicated for CINV.
24
Q

In California, cannabis is regulated less stringently. Medical use of THC was decriminalized in California in 1996. In 2014, non-medical use of cannabis and cannabis products (for adults) was permitted. In California and other states where marijuana is legal, CBD derived from the cannabis plant is…

A

taxed and regulated.

25
Q

According to federal law, CBD derived from any source (including hemp) cannot be used in dietary supplements or as food additive since CBD is available as a Rx drug (Epidiolex). However, the DEA has made 2 recent changes pertaining to cannabis products:

A
  • In 2018, the Farm Bill was signed into federal law, which removed hemp from the definition of marijuana in the CSA. Since hemp products are legal, CBD can be extracted from hemp and used in topical products (eg, cream, oil, sprays)
  • The FDA still regulates hemp and hemp-derived products, but they are no longer classified as schedule I. This has allowed the retail pharmacist to begin selling CBD-containing topical products in select states, including California.
26
Q

Pharmacies are not allowed to sell marijuana or drug paraphernalia due to federal law. Even though marijuana is not dispensed in pharmacies, pharmacists should add marijuana to a patient’s medication profile, and be aware of potential drug interactions. CBD and THC are CNS depressants which can…

A

cause additive side effects. Both are also substrates of several CYP450 enzymes (ie. inducers decrease and inhibitors increase CBD/THC levels.
