APLASTIC ANEMIA AND AGRANULOCYTOSIS HAVE BEEN REPORTED IN ASSOCIATION WITH THE USE OF CARBAMAZEPINE. DATA FROM A POPULATION-BASED CASE CONTROL STUDY DEMONSTRATE THAT THE RISK OF DEVELOPING THESE REACTIONS IS 5-8 TIMES GREATER THAN IN THE GENERAL POPULATION. HOWEVER, THE OVERALL RISK OF THESE REACTIONS IN THE UNTREATED GENERAL POPULATION IS LOW, APPROXIMATELY SIX PATIENTS PER ONE MILLION POPULATION PER YEAR FOR AGRANULOCYTOSIS AND TWO PATIENTS PER ONE MILLION POPULATION PER YEAR FOR APLASTIC ANEMIA.
ALTHOUGH REPORTS OF TRANSIENT OR PERSISTENT DECREASED PLATELET OR WHITE BLOOD CELL COUNTS ARE NOT UNCOMMON IN ASSOCIATION WITH THE USE OF CARBAMAZEPINE, DATA ARE NOT AVAILABLE TO ESTIMATE ACCURATELY THEIR INCIDENCE OR OUTCOME. HOWEVER, THE VAST MAJORITY OF THE CASES OF LEUKOPENIA HAVE NOT PROGRESSED TO THE MORE SERIOUS CONDITIONS OF APLASTIC ANEMIA OR AGRANULOCYTOSIS.
BECAUSE OF THE VERY LOW INCIDENCE OF AGRANULOCYTOSIS AND APLASTIC ANEMIA, THE VAST MAJORITY OF MINOR HEMATOLOGIC CHANGES OBSERVED IN MONITORING OF PATIENTS ON CARBAMAZEPINE ARE UNLIKELY TO SIGNAL THE OCCURRENCE OF EITHER ABNORMALITY. NONETHELESS, COMPLETE PRETREATMENT HEMATOLOGICAL TESTING SHOULD BE OBTAINED AS A BASELINE. IF A PATIENT IN THE COURSE OF TREATMENT EXHIBITS LOW OR DECREASED WHITE BLOOD CELL OR PLATELET COUNTS, THE PATIENT SHOULD BE MONITORED CLOSELY. DISCONTINUATION OF THE DRUG SHOULD BE CONSIDERED IF ANY EVIDENCE OF SIGNIFICANT BONE MARROW DEPRESSION DEVELOPS.
CARBAMAZEPINE TABLETS, USP
Carbamazepine is an anticonvulsant and specific analgesic for trigeminal neuralgia, available for oral administration as chewable tablets of 100 mg and tablets of 200 mg.
Carbamazepine is indicated for use as an anticonvulsant drug. Evidence supporting efficacy of carbamazepine as an anticonvulsant was derived from active drug‑controlled studies that enrolled patients with the following seizure types:
- Partial seizures with complex symptomatology (psychomotor, temporal lobe). Patients with these seizures appear to show greater improvement than those with other types.
- Generalized tonic-clonic seizures (grand mal).
- Mixed seizure patterns which include the above, or other partial or generalized seizures. Absence seizures (petit mal) do not appear to be controlled by carbamazepine (see PRECAUTIONS, General).
Carbamazepine is indicated in the treatment of the pain associated with true trigeminal neuralgia.
Beneficial results have also been reported in glossopharyngeal neuralgia.
This drug is not a simple analgesic and should not be used for the relief of trivial aches or pains.

The effect of levetiracetam monotherapy on subjective sleep quality and objective sleep parameters in patients with epilepsy: compared with the effect of carbamazepine-CR monotherapy. [2011.05]
PURPOSE: There is relatively little known about the effects of new antiepileptic drugs (AEDs) on sleep. This study was done to evaluate the effect of levetiracetam (LEV) on subjective sleep quality and sleep architecture in patients with epilepsy, and the results were compared with the effects of carbamazepine-CR (CBZ-CR)... CONCLUSION: LEV may increase sleep efficiency without major effects on sleep structure with an overall effect on sleep parameters comparable to CBZ-CR.

Pregabalin effect on steady-state pharmacokinetics of carbamazepine, lamotrigine, phenobarbital, phenytoin, topiramate, valproate, and tiagabine. [2011.02]
By reducing neuronal excitability through selective binding to the alpha(2)delta subunit of voltage-dependent calcium channels, pregabalin effectively treats epilepsy, chronic pain, and anxiety disorders. To evaluate if pregabalin coadministration affects pharmacokinetics of other antiepileptic drugs, population pharmacokinetic analyses using NONMEM software were performed on data from three epilepsy trials involving seven antiepileptic drugs with pregabalin as add-on therapy...

Clinical Trials Related to Carbamazepine
Olanzapine Plus Carbamazepine in the Treatment of Bipolar I Mania [Completed]
This trial will assess any efficacious benefit and any safety issues associated with the
concomitant use of olanzapine and carbamazepine for the treatment of patients with bipolar I
disorder, manic or mixed episodes
Open Label Study of Lithium Plus Extended-Release Carbamazepine (ERC-CBZ) for Rapid Cycling Bipolar Disorder [Active, not recruiting]
This is an open label design using Lithium plus extended release carbamazepine (Equetro) in
combination for 6 months. Rapid cycling bipolar disorder is frequently treatment refractory
and associated with repeated hospitalizations and complications. The results of this study
will offer a promising approach to treat this complex disorder. The primary efficacy measure
will be the time to relapse. Relapse will determined by the investigator based on the
following: Need for additional pharmacotherapy for mood-related symptoms, hospitalization for
an mood episode, increase of more than 50% in HAM-D and YMRS scores from the baseline visit.
Study to Assess the Safety and Tolerability of Intravenous Carbamazepine in Adults With Epilepsy [Recruiting]
The purpose of this study is to assess the safety and tolerability of intravenous (IV)
carbamazepine (CBZ) administered as multiple 15 minute infusions to adult patients with
epilepsy on stable higher doses of oral CBZ.
A Double-blind Study to Compare the Efficacy and Safety of Zonisamide and Carbamazepine as Monotherapy, in Newly Diagnosed Partial Epilepsy [Recruiting]
This is a two-arm, randomized, double-blind, non-inferiority study using a flexible dosing
regime to allow optimal zonisamide or carbamazepine therapy for individual subjects.
Assessment of eligibility will take place at the Screening Visit. The subjects will be
randomized to either the carbamazepine or zonisamide arm at the Randomization Visit (T1). T1
must occur as soon as possible (and at least within 14 days) of the Screening Visit in order
to optimize subject care.
