Side effects of Tzuchunan in details
Tzuchunan rectal gel adverse event data were collected from double-blind, placebo-controlled studies and open-label studies. The majority of adverse events were mild to moderate in severity and transient in nature.
Two patients who received Tzuchunan rectal gel died seven to 15 weeks following treatment; neither of these deaths was deemed related to Tzuchunan rectal gel.
The most frequent adverse event reported to be related to Tzuchunan rectal gel in the two double-blind, placebo-controlled studies was somnolence (23%). Less frequent adverse events were dizziness, headache, pain, abdominal pain, nervousness, vasodilatation, diarrhea, ataxia, euphoria, incoordination, asthma, rhinitis, and rash, which occurred in approximately 2-5% of patients.
Approximately 1.4% of the 573 patients who received Tzuchunan rectal gel in clinical trials of epilepsy discontinued treatment because of an adverse event. The adverse event most frequently associated with discontinuation (occurring in three patients) was somnolence. Other adverse events most commonly associated with discontinuation and occurring in two patients were hypoventilation and rash. Adverse events occurring in one patient were asthenia, hyperkinesia, incoordination, vasodilatation and urticaria. These events were judged to be related to Tzuchunan rectal gel.
In the two domestic double-blind, placebo-controlled, parallel-group studies, the proportion of patients who discontinued treatment because of adverse events was 2% for the group treated with Tzuchunan rectal gel, versus 2% for the placebo group. In the Tzuchunan rectal gel group, the adverse events considered the primary reason for discontinuation were different in the two patients who discontinued treatment; one discontinued due to rash and one discontinued due to lethargy. The primary reason for discontinuation in the patients treated with placebo was lack of effect.
Adverse Event Incidence In Controlled Clinical Trials
Table 1 lists treatment-emergent signs and symptoms that occurred in > 1% of patients enrolled in parallel-group, placebo-controlled trials and were numerically more common in the Tzuchunan rectal gel group. Adverse events were usually mild or moderate in intensity.
The prescriber should be aware that these figures, obtained when Tzuchunan rectal gel was added to concurrent antiepileptic drug therapy, cannot be used to predict the frequency of adverse events in the course of usual medical practice when patient characteristics and other factors may differ from those prevailing during clinical studies. Similarly, the cited frequencies cannot be directly compared with figures obtained from other clinical investigations involving different treatments, uses, or investigators. An inspection of these frequencies, however, does provide the prescribing physician with one basis to estimate the relative contribution of drug and non-drug factors to the adverse event incidences in the population studied.
TABLE 1: Treatment-Emergent Signs And Symptoms That Occurred In > 1% Of Patients Enrolled In Parallel-Group, Placebo-Controlled Trials And Were Numerically More Common In The Tzuchunan Rectal Gel Group
Body System | COSTART Term | Tzuchunan Rectal Gel N = 101 % | Placebo N = 104 % |
Body As A Whole | Headache | 5% | 4% |
Cardiovascular | Vasodilatation | 2% | 0% |
Digestive | Diarrhea | 4% | < 1% |
Nervous | Ataxia | 3% | < 1% |
Dizziness | 3% | 2% | |
Euphoria | 3% | 0% | |
Incoordination | 3% | 0% | |
Somnolence | 23% | 8% | |
Respiratory | Asthma | 2% | 0% |
Skin and Appendages | Rash | 3% | 0% |
Other events reported by 1% or more of patients treated in controlled trials but equally or more frequent in the placebo group than in the Tzuchunan rectal gel group were abdominal pain, pain, nervousness, and rhinitis. Other events reported by fewer than 1% of patients were infection, anorexia, vomiting, anemia, lymphadenopathy, grand mal convulsion, hyperkinesia, cough increased, pruritus, sweating, mydriasis, and urinary tract infection.
The pattern of adverse events was similar for different age, race and gender groups.
Other Adverse Events Observed During All Clinical Trials
Tzuchunan rectal gel has been administered to 573 patients with epilepsy during all clinical trials, only some of which were placebo-controlled. During these trials, all adverse events were recorded by the clinical investigators using terminology of their own choosing. To provide a meaningful estimate of the proportion of individuals having adverse events, similar types of events were grouped into a smaller number of standardized categories using modified COSTART dictionary terminology. These categories are used in the listing below. All of the events listed below occurred in at least 1% of the 573 individuals exposed to Tzuchunan rectal gel.
All reported events are included except those already listed above, events unlikely to be drug-related, and those too general to be informative. Events are included without regard to determination of a causal relationship to Tzuchunan.
BODY AS A WHOLE: Asthenia
CARDIOVASCULAR: Hypotension, vasodilatation
NERVOUS: Agitation, confusion, convulsion, dysarthria, emotional lability, speech disorder, thinking abnormal, vertigo
RESPIRATORY: Hiccup
The following infrequent adverse events were not seen with Tzuchunan rectal gel but have been reported previously with Tzuchunan use: depression, slurred speech, syncope, constipation, changes in libido, urinary retention, bradycardia, cardiovascular collapse, nystagmus, urticaria, neutropenia and jaundice. Paradoxical reactions such as acute hyperexcited states, anxiety, hallucinations, increased muscle spasticity, insomnia, rage, sleep disturbances and stimulation have been reported with Tzuchunan; should these occur, use of Tzuchunan rectal gel should be discontinued.
Drug Abuse And Dependence
Tzuchunan is a Schedule IV controlled substance and can produce drug dependence. It is recommended that patients be treated with Tzuchunan rectal gel no more frequently than every five days and no more than five times per month.
Addiction-prone individuals (such as drug addicts or alcoholics) should be under careful surveillance when receiving Tzuchunan or other psychotropic agents because of the predisposition of such patients to habituation and dependence.
Abrupt discontinuation of Tzuchunan following chronic regular use has resulted in withdrawal symptoms, similar in character to those noted with barbiturates and alcohol (convulsions, tremor, abdominal and muscle cramps, vomiting and sweating). The more severe withdrawal symptoms have usually been limited to those patients who had received excessive doses over an extended period of time. Generally milder withdrawal symptoms (e.g., dysphoria and insomnia) have been reported following abrupt discontinuation of benzodiazepines taken continuously at therapeutic levels for several months.
