RESUMO

BACKGROUND: Exposure of children under 5 years to button batteries may result in severe corrosive injury, especially when they get stuck in the oesophagus. The injury is caused by the discharge current of the batteries. An increasing number of button battery ingestions have been described worldwide. OBJECTIVES: The aim of this study was to describe incidence and complications after battery ingestion in children in Germany. MATERIALS AND METHODS: Paediatric gastroenterologists and paediatric surgeons were asked to report complicated battery ingestions in children between 2011 and 2016 retrospectively. The survey was done using a structured questionnaire. In addition, button battery ingestion calls to a German poison centre were analysed retrospectively. RESULTS: In 116 cases the button battery was located in the oesophagus. Severe complications developed in 47 patients and 5 of these children died. Serious complications occurred also in children with removal of the button batteries within less than 3 h after the intake. The Freiburg poison centre received 258 paediatric ingestions of button batteries. Out of these, seven button batteries were stuck in the oesophagus and five in the nose causing corrosion injury. CONCLUSIONS: Serious complications and even death after button battery ingestion are described in Germany. Button batteries impacted in the oesophagus should be removed emergently to minimize corrosive injury. Because no symptoms or only slight discomfort are developed initially, awareness of button batteries as a unique corrosive hazard among the public and clinicians is an important requirement for prompt diagnosis and treatment resulting in a satisfactory outcome.

RESUMO

BACKGROUND: Plant poisoning in small children (from 0.5 to <6 years of age) is the third most frequent cause for phone contact with a poison center. For prevention of poisonings, a list of poisonous plants that should not be planted close to playgrounds or other places frequently visited by children was published in 2000 by the Bundesanzeiger. This list has been reevaluated and updated by the "Toxicity of Plants" working group of the Committee of the Assessment of Intoxications at the Federal Institute of Risk Assessment (BfR). MATERIALS AND METHODS: Relevant plants were taken from a recent publication. A literature search was conducted in PubMed concerning all plant poisonings in children and the toxic ingredients of plants. Also, monographs and the database POISINDEX were integrated in the evaluation. A classification was made for plants that after oral, dermal, or ocular contact of small quantities could cause severe, moderate, mild, or no intoxications in small children. RESULTS: Based on data of exposure and potentially toxic ingredients of the involved plants, a risk assessment was executed, which diverges from other publications because it concerns the actual basic risk of an intoxication. In total, 251 plants were reevaluated. For 11 plants, there was a high risk, for 32 a moderate, for 115 a mild, and for 93 plants no risk of intoxication could be determined. CONCLUSION: The new assessment of evaluating a toxicity risk for small children on the basis of exposure data and including the toxicity of ingredients allows for a more realistic assessment of the risk of poisoning with outdoor plants. In this way, infant exposure carrying a high risk of intoxication can be identified.

RESUMO

Exotic poisonous animals such as snakes, marine animals, spiders, and scorpions are a rarity in Central Europe, but are kept as pets by some people. Poisoning caused by these animals is a particular challenge in medical care.Over a period of six years (2001-2006), a total of 202 cases of poisoning with exotic animals were registered and evaluated at four poison information centers in Germany and France. Of the accidents, 91% happened in the home environment; the rest in pet stores. The poisonings were caused by snakes (38%), marine animals (31%), arthropods (spiders and scorpions, 27%), and other poisonous animals (4%). Severe poisoning was involved in 8% of the cases, all caused by snake bites. The severe poisonings were in the form of coagulopathies, severe local symptoms, and a respiratory insufficiency requiring intubation. In six cases of severe poisoning, an immune serum (antivenom) was administered and in three cases a surgical procedure was needed. Deaths did not occur.After the bite of a poisonous animal, the affected limb should usually be immobilized and disinfected, but not tied, cut, or sucked. The exact biological name of the species should be identified. In addition to hospitalization, it is recommended to consult a poison information center.

RESUMO

BACKGROUND AND OBJECTIVES: Accidental exposure of children to plants occurs often and results in numerous calls to poison centres. The aim of this study was to identify outdoor plants that led to moderate or severe poisoning after accidental exposure and to identify patterns of paediatric plant exposures. MATERIALS AND METHODS: Human exposure data on accidental exposures provided by two German poison centres were retrospectively evaluated regarding the number and the routes of exposure. Special attention was turned to the kind and severity of symptoms. Based on these data a modified Litovitz factor was calculated. RESULTS: Out of 42,344 confirmed exposures to 227 plant species, 39,346 (93%) were asymptomatic, 2415 (5.7%) experienced minor, 580 (1.3%) moderate and 3 (0.007%) severe symptoms. Twenty-six plant genera were responsible for 70% of all exposures. Only eight of these plants (Arum spec., Laburnum anagyroides, Narcissus spec., Phaseolus vulgaris/coccineus, Prunus laurocerasus, Sambucus spec., Taxus baccata, Thuja spec.) led to at least moderate symptoms. Accidental exposure of children aged 0.5-5 years was mainly by oral ingestion (98%) and involved mostly fruits (60%). CONCLUSIONS: Exposure data collected by poison centres are very useful for hazard identification of outdoor plants. The data give a comprehensive overview of observed symptoms, which offers valuable instruments for use in clinical practice.

RESUMO

The detection of drug metabolites in hair is widely accepted as a proof for systemic uptake of the drug, unless the metabolites can be formed as artefacts. However, regarding synthetic cannabinoids, not much is known about mechanisms of incorporation into hair. For a correct interpretation concerning hair findings of these compounds and their metabolites, it is necessary to identify the different routes of incorporation and to assess their contribution to analytical findings. This study presents the results of the LC-ESI-MS/MS analysis of an authentic hair sample taken from a patient with a known history of heavy consumption of synthetic cannabinoids. In the authentic hair sample, 5F-PB-22 and AB-CHMINACA as well as their main metabolites 5F-PB-22 3-carboxyindole, PB-22 5-OH-pentyl, and AB-CHMINACA valine were detected in all segments, comprising segments grown in a time period where the substances had not been distributed on the 'legal high' market. To enable interpretation of the results regarding the distribution of the detected analytes along the hair shaft, the stability of 5F-PB-22 and AB-CHMINACA in hair matrix and under thermal stress was assessed. The stability tests revealed that the three 'metabolites' are also formed in externally contaminated hair after storage of the samples under different conditions. In addition, 5F-PB-22 3-carboxyindole and AB-CHMINACA valine were identified as degradation products in smoke condensate. Therefore, interpretation of 'metabolite' findings of compounds comprising chemically labile amide/ester bonds or 5-fluoro-pentyl side chains should be carried out with utmost care, taking into account the different mechanisms of formation and incorporation into hair.

RESUMO

Eliglustat is an orphan medicine used for long-term treatment of Gaucher disease type 1 (GD1) in adults. GD1 is a genetic condition, in which glucosylceramide builds up in the body, typically in liver, spleen, and bone. Clinical signs and symptoms of the disease are anemia, tiredness, easy bruising, hepatosplenomegaly, bone pain, and fractures. Eliglustat works by blocking glucosylceramide synthase (substrate reduction therapy). This medicine is subject to additional safety monitoring by regulatory authorities in the European Union. Scientific literature on eliglustat overdose is not available. We herein describe successful treatment of a suicidal attempt with massive eliglustat overdose. A 29-year-old female with GD1, a poor metabolizer of cytochrome P450 2D6 on a recommended daily dose of 84 mg of eliglustat, had taken 94 capsules of eliglustat (84 mg per capsule). One hour after ingestion of almost 8 g of eliglustat, the patient suffered from somnolence, severe bradycardia (37 bpm), and hypotension (systolic blood pressure of 70 mm Hg). After intravenous administration of atropine (1 mg) and cafedrine/theoadrenaline (100 mg/5 mg) by the called emergency physician, the patient resolved gradually. She remained 24 h with stable hemodynamics at a nearby intensive care unit. During continuous ECG monitoring, increased frequency of supraventricular ectopic activity and a first-degree atrioventricular block were observed. To our knowledge, this is the first case report on a suicidal attempt with eliglustat.

RESUMO

CONTEXT: New psychoactive substances (NPS) have become an ongoing threat to public health. To prevent the emergence and spread of NPS, a new German law, the 'NpSG' took effect in November 2016. This study presents an overview of analytically confirmed synthetic cannabinoid (SC) intoxications from January 2015 to December 2018. In order to demonstrate effects of the NpSG, the results of 23 month before and 25 month after the introduction of the law were compared. METHODS: Within the scope of a prospective observational study blood and urine samples were collected from emergency patients with suspected NPS intoxication. Comprehensive drug analyses were performed by LC-MS/MS analysis. RESULTS: In the period considered, 138 patients were included. Within these, SC intake was verified in 65 patients (73%) in the period before the law change, and in 30 patients (61%) after. The median age increased significantly from 19.5 to 26 years. Seizures and admission to the ICU were reported significantly less frequently (seizures 29% versus 6.7%, p = 0.0283; ICU admission 42% versus 13%, p = 0.0089). 34 different SCs were detected, including four SCs (Cumyl-PEGACLONE, 5 F-MDMB-P7AICA, EG-018, 5 F-Cumyl-P7AICA) not covered by the NpSG at the time of detection. In the first period the most prevalent SC was MDMB-CHMICA (n = 24). 5 F-ADB was the most prevalent SC overall, detected in 7 patients (11%) in the first, and in 24 patients (80%) in the second period. CONCLUSION: The number of SC intoxications decreased overall after the implementation of the NpSG. The shift in the detected SCs can be considered a direct effect of the NpSG but unfortunately the market supply does not appear to have been reduced. Although changes in the age distribution and in the severity of intoxications may be seen as secondary effects of the law, the main objectives of the new law to prevent the emergence and spread of further chemical variations of known scheduled drugs, have apparently not been achieved from the perspective of this study.

RESUMO

An LC-MS/MS method for the determination of the atypic neuroleptic clozapine and its two main metabolites norclozapine and clozapine-N-oxide has been developed and validated for serum and urine. After addition of d4-clozapine as deuterated internal standard a fast single-step liquid-liquid extraction under alkaline conditions and with ethyl acetate as organic solvent followed. The analytes were chromatographically separated on a Synergi Polar RP column using gradient elution with 1 mM ammonium formate and methanol. Data acquisition was performed on a QTrap 2000 tandem mass spectrometer in multiple reaction monitoring mode with positive electrospray ionization. Two transitions were monitored for each analyte in order to fulfill the established identification criteria. The validation included the determination of the limits of quantification (1.0 ng/mL for all analytes in serum and 2.0 ng/mL for all analytes in urine), assessment of matrix effects (77% to 92% in serum, 21 to 78% in urine) and the determination of extraction efficiencies (52% to 85% for serum, 59% to 88% for urine) and accuracy data. Imprecision was <10%, only the quantification of norclozapine in urine yielded higher relative standard deviations (11.2% and 15.7%). Bias values were below ±10%. Dilution of samples had no impact on the correctness for clozapine and norclozapine in both matrices and for clozapine-N-oxide in serum. For quantification of clozapine-N-oxide in urine a calibration with diluted calibrators has to be used. Calibration curves were measured from the LOQ up to 2,000 ng/mL and proved to be linear over the whole range with regression coefficients higher than 0.98. The method was finally applied to several clinical serum and urine samples and a cerebro-spinal fluid sample of an intoxicated 13-month-old girl.

RESUMO

From 2008 to the end of 2009 the Joint Poison Information Center (PIC) in Erfurt observed 7 incidents involving 17 persons (1 fatality) with signs of carbon monoxide poisoning from indoor barbecues (COFIB). To find out whether COFIB is a regional or a general phenomenon in Germany, Austria and Switzerland, all information about COFIBs recorded by the 11 German-speaking Poison Information Centers and the BfR Berlin were retrospectively analyzed for the period 2000 to 2009. In all, 60 COFIBs (accidental: 90.0 %, suicidal: 8.3%, reason unknown: 1.7%) involving 146 individuals were reported. The number of incidents increased from one case with 2 persons in 2000 to 18 cases involving 34 persons in 2009. The 146 victims (female 26.7%, male 27.4%, gender unknown 45.9%; adults 58.2%, children 24.7%, age unknown 17.1%) lived in 15 of the 16 federal states of Germany and in Switzerland. The highest number of victims was found in Bavaria (23), Brandenburg (18), and Baden-Wuerttemberg (18). The symptoms according to the Poisoning Severity Score were none to mild in 60.3%, moderate in 13.7%, severe in 11.6%, fatal in 6.9% and unratable in 7.5%. No clear correlation was found between the carboxyhemoglobin concentration and the severity of the symptoms. As a rising number of COFIBs often involving several individuals was observed from 2000 to 2009, the general public was informed about the risks of indoor barbecues.

RESUMO

BACKGROUND: Since 2016 an increase has been observed in the availability of new synthetic opioids (NSO) in Europe. Cyclopropylfentanyl is a very potent and selective µ-opioid agonist, which was reported for the first time in August 2017 in Europe. METHODS: The case was included in a prospective observational study of patients treated in emergency departments after the intake of novel psychoactive substances (NPS). Clinical features were acquired using a structured questionnaire for physicians. Serum and/or urine samples of ED patients were analyzed using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) screening methods for NPS. CASE REPORT: Within 10 min after intranasal intake of fentanyl, a 25-year-old male developed nausea, profuse sweating and dyspnoe. Because soon afterwards coma and respiratory insufficiency was noticed, the patient was admitted to hospital. After administration of naloxone (0.8 mg) breathing stabilized. However, the patient displayed recurrent decreases of oxygen saturation for 12 h. The intake of cyclopropylfentanyl was analytically confirmed. CONCLUSION: The constantly growing diversity of NSO still poses a high risk for drug users and can be a challenging task for clinicians and forensic toxicologists. Clinicians treating opioid overdoses should be aware of the potentially long lasting respiratory depression induced by fentanyl analogs.

RESUMO

This work presents two cases of codeine intoxication in 3-year-old monozygotic twin brothers while treated with a codeine slow-release formulation. One child had to be admitted to the hospital, whereas the other one died at home after aspiration of gastric content. The concentrations of codeine and major metabolites including morphine and corresponding glucuronide conjugates were measured by liquid chromatography-tandem mass spectrometry in serum, urine, cerebrospinal fluid, and brain tissue, respectively. A genetic polymorphism study was carried out in order to determine the ability of the children to metabolize codeine by O-demethylation. A pharmacokinetic calculation was also performed to estimate the administered dose of codeine in question. High concentrations of all substances were found in samples of both children. The pharmacokinetic estimate suggests an overdose of codeine, and the possible reasons for the high opiate concentrations are discussed. Furthermore, the postmortem distribution--during and after resuscitation--might play a major role in the interpretation of postmortem concentration levels.

RESUMO

UNLABELLED: In spite of the lack of evidence for its efficacy, and of sporadic reports of severe adverse events, codeine is still widely used as an antitussive agent in children. A 3-year-old boy (twin 1) was found lying in vomit and apnoeic at night; he was resuscitated and immediately transferred to our paediatric intensive care unit (PICU). Two and a half hours later, his twin brother (twin 2) was found dead in his bed at home. Twin 1 required mechanical ventilation for 3 days, but he eventually made a full recovery; autopsy in twin 2 showed massive aspiration of gastric content. History revealed that the monozygotic twins had an upper respiratory tract infection for several days and had both been given codeine at a dose of "10 drops per day" by their mother. The blood of both twins was found to contain high levels of codeine and its metabolites. The weight of "10 drops" was determined experimentally and was found to range from 494 to 940 mg. Thus, the highest possible dose given by mother was 23.5 mg of codeine instead of the recommended 10 mg. The twins had identical CYP2D6 gene polymorphisms corresponding to the "extensive metaboliser" type. CONCLUSIONS: Because of the variability of drop size drug dosage, dosage "by drops" is unprecise and may result in accidental overdose. The combination of repeated overdosing and extensive metabolism to morphine is likely to have caused apnoea in these twins. These cases illustrate the danger of codeine as an antitussive in young children.

RESUMO

A variety of hallucinogens of the lysergamide type has emerged on the drug market in recent years and one such uncontrolled derivative of lysergic acid diethylamide (LSD) is 1-propionyl-LSD (1P-LSD). Due to the high potency of LSD and some of its derivatives (common doses: 50-200 µg), sensitive methods are required for the analysis of biological samples such as serum and urine. The occurrence of an intoxication case required the development of a fully validated, highly sensitive method for the quantification of 1P-LSD and LSD in urine and serum using LC-MS/MS. Given that LSD is unstable in biological samples when exposed to light or elevated temperatures, we also conducted stability tests for 1P-LSD in urine and serum under different storage conditions. The validation results revealed that the analysis method was accurate and precise with good linearity over a wide calibration range (0.015-0.4 ng mL-1). The limit of detection (LOD) and the lower limit of quantification (LLOQ) of 1P-LSD and LSD in serum and urine were 0.005 ng mL-1 and 0.015 ng mL-1, respectively. The stability tests showed no major degradation of 1P-LSD in urine and serum stored at -20 °C, 5 °C or at room temperature for up to five days, regardless of protection from light. However, LSD was detected in all samples stored at room temperature showing a temperature-dependent hydrolysis of 1P-LSD to LSD to some extent (up to 21% in serum). Serum samples were particularly prone to hydrolysis possibly due to enzymatically catalyzed reactions. The addition of sodium fluoride prevented the enzymatic formation of LSD. The method was applied to samples obtained from the intoxication case involving 1P-LSD. The analysis uncovered 0.51 ng mL-1 LSD in urine and 3.4 ng mL-1 LSD in serum, whereas 1P-LSD remained undetected. So far pharmacokinetic data of 1P-LSD is missing, but with respect to the results of our stability tests and the investigated case rapid hydrolysis to LSD in-vivo seems more likely than instabilities of 1P-LSD in urine and serum samples.

RESUMO

Objective: Local effects on the eye following cleaning product exposures are frequently reported. According to EU chemicals legislation many cleaning products are labelled with Hazard Phrase 318 indicating risk of irreversible eye damage. The objectives of this study were to identify cleaning products with potential for irreversible eye damage by collecting human exposure data from poisons centres (PC), and to clarify to what degree exact product identification is possible during a PC telephone call. Methods: MAGAM II was a multicentre binational prospective observational PC study. All human eye exposures to detergents or maintenance products reported to nine PCs taking calls from the public and medical professionals during an 18-month period were included. The severity of eye effects was rated according to the WHO Poisoning Severity Score. Results: Five hundred and eighty-six cases were included. Product identification by name leading to formula information was successful in 533 cases (91%). Follow-up was successful in 528 exposures. Irrigation was performed in 94% of cases. Duration of symptoms was ≥24 hours in 73 patients (25%). 33 (6%) patients developed moderate eye injury. Healing was reported in all cases. The percentage of moderate cases was highest in the group of drain cleaners (25%), toilet cleaners (18%) and oven cleaners (15%). Products intended for professional use caused relatively more moderate eye injuries than products also intended for consumer use. Conclusion: MAGAM II has shown that PCs are able to identify formulas in sufficiently high quality as needed for product-directed toxicovigilance. The results underline the potential of PC exposure case data for product safety monitoring. The results indicate that irreversible eye damage is very rare after cleaning product exposure.

RESUMO

A case of human poisoning by palytoxin after contact with zoanthid corals (Parazoanthus sp.) in an aquarium through skin injuries on fingers is reported. The clinical symptoms include swelling, paraesthesia and numbness around the site of the injury spreading over the arm, but also signs of systemic poisoning such as dizziness, general weakness and myalgia, irregularities in the ECG and indications of rhabdomyolysis. Symptomatic treatment consisted of infusion of physiological fluids. The patient recovered within 3 days. Analysis of the zoanthid coral involved revealed extremely high concentrations of palytoxin (between 2 and 3 mg/g).

RESUMO

Novel synthetic opioids and benzodiazepines are an emerging trend on the narcotic drugs market. We present a lethal case of U-47700 and flubromazepam poisoning. A 24-year-old man suffered apnoea after the consumption of the synthetic opioid U-47700 in combination with the benzodiazepine flubromazepam. After reanimation and hospital admission, hypoxic cerebral damage and severe brain oedema were stated. Six days after admission, mechanical ventilation was discontinued, and the patient died. Seven blood serum samples and one urine sample collected during the hospitalisation were analysed by liquid chromatography-tandem mass spectrometry. In the sample collected 42 minutes after admission, the concentrations of U-47700 and flubromazepam were 370 and 830 ng/mL, respectively. Three days later, the concentrations of U-47700 and flubromazepam dropped to 4.2 and 280 ng/mL, respectively. The resulting concentration-time-curves allowed calculating a U-47700 elimination half-life of approximately six hours and confirmed the previously reported flubromazepam elimination half-life of around 100 hours. In the presented case, intoxication by the synthetic opioid U-47700 with a contribution of flubromazepam can be assumed as the cause of death. The concentration-time curves allow an estimation of the clinical course of similar cases. Flubromazepam may lead to prolonged central-nervous depressant effects.

RESUMO

INTRODUCTION: In 2014, the "European Monitoring Centre for Drugs and Drug Addiction" (EMCDDA) reported on 30 novel synthetic cannabinoids (SCs). Among these were indole- and indazole-based valine derivatives with a cyclohexylmethyl side chain (e.g., AB-CHMINACA and MDMB-CHMICA), which represent a new class of SCs. METHODS: A prospective observational study of patients treated in emergency departments (EDs) after the intake of SCs was conducted. Clinical and laboratory data were combined and reported to a poison control centre. Serum and/or urine samples of ED patients were analyzed using LC-MS/MS. RESULTS: Forty four patients (39 male, five female, 12-48 years) were included. AB-CHMINACA (MDMB-CHMICA) was identified in 20 (19) serum samples, and in 21 (25) urine samples, respectively. In 19 of the cases, more than one SC was present. Other psychoactive substances (mainly amfetamines) were identified in seven cases, but in five out of these in urine samples only. Based on the Poison Severity Score, severity of poisoning was minor (4), moderate (31) or severe (9). Most frequently reported neuropsychiatric symptoms were CNS-depression (n = 21, 61%), disorientation (n = 20, 45%), generalized seizures (n = 12, 27%), combativeness (n = 8, 18%) and extreme agitation (n = 7, 16%). Duration of symptoms lasting 24 hours or longer occurred in 15 cases (34%). DISCUSSION: The prevalence of certain neuropsychiatric symptoms was higher in our study than in former reports after the intake of SCs of the aminoalkylindole-type (first generation) SCs. In addition, severe poisoning and duration of symptoms were also higher. CONCLUSIONS: In this study, the valine derivative AB-CHMINACA and the tert-leucine derivative MDMB-CHMICA ("third generation of SCs") seem to be associated with more severe clinical toxicity than was previously reported in patients exposed to earlier generation SCs such as JWH-018. However, this observation needs to be confirmed with a larger cohort of patients with analytically confirmed abuse of third generation SCs. The rapid turnover of SCs on the drug market together with the occurrence of SCs such as AB-CHMINACA and MDMB-CHMICA is alarming, especially because of the unexpectedly high frequency of neuropsychiatric symptoms.

RESUMO

OBJECTIVE: The potent hallucinogenic drug 25I-NBOMe has recently emerged on the drug market. We present a case with analytically confirmed 25I-NBOMe intoxication from the prospective study "SPICE II Plus". CASE REPORT: Because of a severe headache a 42-year-old man took one sip of a pediatric analgesic syrup, which had been refilled with a self-made solution of 25I-NBOMe in ethanol. Thirty minutes later restlessness occurred. On arrival in the emergency department mydriasis, strong sweating, disorientation, and agitation were noticed. Within short time the patient developed severe agitation, coenesthesia, and complex hallucinations. In blood serum samples obtained at admission revealed the presence of 25I-NBOMe (34 ng/mL), 2C-I (12 ng/mL) and 25I-NBOH (<1 ng/mL) (LC-ESI-MS/MS). The presumed analgesic syrup contained 25I-NBOMe (2800 µg/mL), and besides ethanol no other compounds were detected. After six hours, the symptoms resolved without further complications. CONCLUSIONS: This is a unique case of an analytically confirmed, accidental ingestion of 25I-NBOMe in a drug naïve adult. The finding of 2C-I in the serum sample 50 minutes after intake indicates a fast metabolic breakdown of 25I-NBOMe due to first-pass metabolism.

RESUMO

In the presented case, a young healthy woman had ordered a Chinese herbal medicine, called "LiDa Dai Dai Hua Jiao Nang", via internet. She took this product for approximately 1 week, but on the second day she developed severe headache, vertigo and sensation of numbness. After discontinuing medication, symptoms disappeared within 2 days. For identification of the ingredients, a urine sample as well as a sample of the "LiDa" capsule were analysed by GC-MS and HPLC-DAD. One major ingredient was detected in urine as well as in the "LiDa" capsule and was identified as sibutramine. Quantification by HPLC-DAD yielded 27.4 mg sibutramine base, which is approximately two times the amount of the highest authorized single dose available on the pharmaceutical market in Germany. This case demonstrates a common problem with herbal medicines, where adulterations with synthetic therapeutic substances can lead to severe side effects and/or potentially fatal interactions with conventional medicines.
