Calcium D-glucarate and Diazepam

Here is the interaction we found between these two, with the evidence behind it.

Moderate

GLUCURONIDATED DRUGS

Why this applies to Diazepam

Diazepam falls under GLUCURONIDATED DRUGS — the group Calcium D-glucarate interacts with.

Theoretically, calcium D-glucarate might increase the clearance of drugs that undergo glucuronidation.
The calcium D-glucarate metabolite, D-glucaro-1,4-lactone, inhibits the enzyme beta-glucuronidase, reducing deconjugation of glucuronides in the intestine and thereby reducing reabsorption of the drugs.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Valium (diazepam) and calcium D-glucarate. Your body partly clears diazepam and its active leftovers by tagging them with a molecule so they can leave through your gut. Normally a gut enzyme called beta-glucuronidase can flip some of that back and let the drug get reabsorbed. Calcium D-glucarate is thought to block that enzyme, so a bit less diazepam gets recycled and slightly more leaves your system.

In plain terms, this could make diazepam a touch weaker over time, so you might notice less calming or anxiety relief. The good news: this is mostly theoretical, drawn from lab work rather than solid human studies, so the real-world effect is probably small. Still, since diazepam treats things like seizures and severe anxiety, don't change anything on your own. Check with your pharmacist or doctor first.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

About Diazepam

What Is Diazepam Used For?

Brand names: Valium, Valium injection, Diastat AcuDial, Valtoco

  • Diazepam is used to relieve anxiety and to control agitation caused by alcohol withdrawal. It is also used along with other medications to control muscle spasms and spasticity caused by certain neurological disorders such as cerebral palsy (condition that causes difficulty with movement and balance), paraplegia (inability to move parts of the body), athetosis (abnormal muscle contractions), and stiff-man syndrome (a rare disorder with muscle rigidity and stiffness). Diazepam is also used along with other medications to control seizures. Diazepam is in a class of medications called benzodiazepines. It works by calming abnormal overactivity in the brain.
