Abstract
AIMS Climate change represents the biggest global health threat of the 21st century. Health care system is itself a large contributor to greenhouse gas (GHG) emissions. In cardiology, atrial fibrillation (AF) catheter ablation is an increasing activity using numerous non-reusable materials that could contribute to GHG emission. Determining a detailed carbon footprint analysis of an AF catheter ablation procedure allows the identification of the main polluting sources that give opportunities for reduction of environmental impact. To assess the carbon footprint of AF catheter ablation procedure. To determine priority actions to decrease pollution. METHODS AND RESULTS An eco-audit method used to predict the GHG emission of an AF catheter ablation procedure was investigated. Two workstations were considered including surgery and anaesthesia. In the operating room, every waste produced by single-use medical devices, pharmaceutical drugs, and energy consumption during intervention were evaluated. All analyses were limited to the operating room. Thirty procedures were analysed over a period of 8 weeks: 18 pulmonary veins isolation RF ablations, 7 complex RF procedures including PVI, roof and mitral isthmus lines, ethanol infusion of the Marshall vein and cavo tricuspid isthmus line, and 5 pulmonary vein isolation with cryoballoon. The mean emission during AF catheter ablation procedures was 76.9 kg of carbon dioxide equivalent (CO2-e). The operating field accounted for 75.4% of the carbon footprint, while only 24.6% for the anaesthesia workstation. On one hand, material production and manufacturing were the most polluting phases of product life cycle which, respectively, represented 71.3% (54.8 kg of CO2-e) and 17.0% (13.1 kg of CO2-e) of total pollution. On the other hand, transport contributed in 10.6% (8.1 kg of CO2-e), while product use resulted in 1.1% (0.9 kg of CO2-e) of GHG production. Electrophysiology catheters were demonstrated to be the main contributors of environmental impact with 29.9 kg of CO2-e (i.e. 38.8%). Three dimensional mapping system and electrocardiogram patches were accounting for 6.8 kg of CO2-e (i.e. 8.8% of total). CONCLUSION AF catheter ablation involves a mean of 76.9 kg of CO2-e. With an estimated 600 000 annual worldwide procedures, the environmental impact of AF catheter ablation activity is estimated equal to 125 tons of CO2 emission each day. It represents an equivalent of 700 000 km of car ride every day. Electrophysiology catheters and patches are the main contributors of the carbon footprint. The focus must be on reducing, reusing, and recycling these items to limit the impact of AF ablation on the environment. A road map of steps to implement in different time frames is proposed.

Abstract
Background Studies suggest that performing an electrophysiological study (EPS) may be useful to identify patients with new-onset left bundle branch block (LBBB) post-TAVR at risk of atrioventricular block. However, tools to optimize the yield of such strategy are needed. We therefore aimed to investigate whether 12-lead ECG changes post-TAVR may help identify patients with abnormal EPS findings. Materials and methods Consecutive patients with new-onset LBBB post-TAVR who underwent EPS were included. PR and QRS intervals were measured on 12-lead ECG pre-TAVR and during EPS. Abnormal EPS was defined as an HV interval > 55 ms. Results Among 61 patients, 28 (46%) had an HV interval > 55 ms after TAVR. Post-TAVR PR interval and ΔPR (PR-post–pre-TAVR) were significantly longer in patients with prolonged HV (PR: 188 ± 38 vs. 228 ± 34 ms, p < 0.001, ΔPR: 10 ± 30 vs. 34 ± 23 ms, p = 0.001), while no difference was found in QRS duration. PR and ΔPR intervals both effectively discriminated patients with HV > 55 ms (AUC = 0.804 and 0.769, respectively; p < 0.001). A PR > 200 ms identified patients with abnormal EPS results with a sensitivity of 89% and a negative predictive value (NPV) of 88%. ΔPR ≥ 20 ms alone provided a somewhat lower sensitivity (64%) but combining both criteria (i.e., PR > 200 ms or ΔPR ≥ 20 ms) identified almost every patients with abnormal HV (sensitivity = 96%, NPV = 95%). Selecting EPS candidate based on both criteria would avoid 1/3 of exams. Conclusion PR interval assessment may be useful to select patients with new-onset LBBB after TAVR who may benefit most from an EPS. In patients with PR ≤ 200 ms and ΔPR < 20 ms the likelihood of abnormal EPS is very low independently of QRS changes.

Background
Sudden cardiac death (SCD) is one of the leading causes of death, particularly among patients with myocardial scars. Implantable cardioverter defibrillators (ICD) are recommended in patients with a left ventricular ejection fraction (LVEF) ≤ 35%. Another recognised indication is the induction of sustained ventricular tachycardia (VT) or ventricular fibrillation (VF) during programmed ventricular stimulation (PVS) in post-myocardial infarction patients with non-sustained VT and a LVEF between 35% and 40%. However, no recommendation exists to guide the use of prophylactic ICD implantation in patients with less altered LVEF, even though they represent the majority of SCDs.
Purpose
We aimed to evaluate the prognostic value of PVS in patients with myocardial scars and a relatively preserved LVEF (≥ 40%).
Methods
Patients with evidence of a chronic myocardial scar and a LVEF ≥ 40%, who underwent PVS at two hospital centers were considered for inclusion. Ischemic and non-ischemic myocardial scars were included. The primary endpoint was the occurrence of a Major Arrhythmic Event (MAE), namely SCD, clinical VT/ventricular fibrillation, or appropriate ICD therapy.
Results
134 patients were included (mean age 62.4 ± 12.5 years, LVEF 54.7 ± 8.6 %). Indication for PVS was mostly non-sustained VT and/or syncope (84%). Post-myocardial infarction patients represented about half of the cases (53%). Inducibility during PVS was observed in 17 patients (13%). There was a nonsignificant trend towards higher inducibility rates in ischemic versus nonischemic scars (17% and 8%, respectively; p-value = 0.1). Of these patients, 15 received an ICD (88%). Over a mean follow-up of 49 (±42) months, a MAE occurred in 7 patients (41.2%) with positive PVS, versus 4 patients (3.4%) with negative PVS. MAE-free survival at 10 years was 91% and 43% in PVS-negative and PVS-positive patients, respectively (p-value < 0.001). One SCD occurred in a PVS-positive patient who denied prophylactic ICD implantation. Inducibility during PVS provided a 64% sensitivity and a 97% negative predictive value (PV) to predict the occurrence of MAE (specificity 92%, positive PV 41%).
Conclusion
PVS is a useful tool to discriminate patients with myocardial scars and LVEF ≥ 40% at increased arrhythmic risk. Effective utilisation of ICD may be anticipated in case of positive PVS, while non-inducible patients are at lower MAE risk.

Abstract
Abstract
Background
The diagnosis of inflammatory cardiomyopathy remains challenging in cases presenting with arrhythmia as sole manifestation. An early diagnosis is critical as it may prevent life-threatening complications such as sudden cardiac death and atrioventricular block (AVB). The diagnostic workup of suspected cases includes multimodality imaging that requires an adequate interpretation in order to limit the risk of overdiagnosis.
Case summary
Herein, we report three cases presenting with various new-onset arrhythmias. The first patient was admitted for a third-degree AVB. The second patient suffered from a supraventricular tachycardia which degenerated into ventricular fibrillation. The third case was investigated for symptomatic premature ventricular complexes. No apparent heart disease was observed on standard exams (clinical, biological examinations, and echocardiography). However, cardiac magnetic resonance imaging (MRI) and nuclear imaging (68Ga-DOTATOC and/or 18F-FDG PET/CT) suggested an inflammatory substrate that seemed to correlate with the arrhythmic phenotype. Cardiac inflammation disappeared on immunotherapy for the first case and spontaneously for the third case.
Discussion
These cases emphasize the incremental diagnostic yield of multimodality imaging to highlight myocardial inflammation. Nuclear imaging modalities may complement MRI by enabling the detection of active inflammation. The 18F-FDG PET/CT is well established for the diagnosis of cardiac sarcoidosis but its role remains to be clarified for the diagnosis of myocarditis. An alternative radiotracer, 68Ga-DOTATOC, appears promising by overcoming the main limitation of 18F-FDG but its specificity is not yet well established. The role of functional investigations is discussed as well as the benefit of immunosuppressive treatments.

Abstract
BACKGROUND The objective of this study was to evaluate the impact of the interaction between body dissatisfaction and gender on eating disorders (restrained eating, binge eating, orthorexia nervosa, and emotional eating) among a sample of Lebanese adults. METHODS This cross-sectional study, conducted between January and May 2018, enrolled 811 participants selected randomly from all Lebanese Mohafazat. The mean age of the participants was 27.6±11.8 years. The majority were females (66.5%), had a high level of education (73.2%), and low income (77.9%). This study used the following scales: body dissatisfaction subscale of the Eating Disorder Inventory-second version, binge eating scale, Dutch restrained eating scale, orthorexia nervosa scale (ORTHO-15 scale), emotional eating scale, perceived stress scale, Hamilton Anxiety Rating Scale, and Hamilton Depression Rating Scale. RESULTS Body dissatisfaction was positively correlated to restrained eating (r=0.293, P<0.001), emotional eating (r=0.073, P=0.042) and binge eating (r=0.250, P<0.001). The interaction between body dissatisfaction and gender was significantly associated with more restrained eating (Beta=0.01, P<0.001) and orthorexia nervosa (Beta=-0.09, P<0.001), but not with emotional (Beta=-0.43, P=0.103) and binge eating (Beta=-0.08, P=0.358). When stratifying the analysis by gender, the results revealed that higher body dissatisfaction was significantly associated with more restrained eating in both genders, but particularly among women. Body dissatisfaction was significantly associated with higher emotional eating in men only and with higher orthorexia nervosa tendencies and behaviors in females only. CONCLUSION The interaction between body dissatisfaction and gender was significantly associated with orthorexia nervosa and restrained eating but not with binge or emotional eating. Higher body dissatisfaction was significantly associated with higher restrained eating, more pronounced in women, while it was significantly associated with higher orthorexia tendencies (lower ORTO-15 scores) in women only. Body dissatisfaction was associated with emotional eating in men only.

Abstract
OBJECTIVE To assess: (1) the association between insomnia experienced at admission, sociodemographic and other patients' characteristics and mania; and (2) the variation of insomnia and mania before and after treatment in bipolar patients with manic episodes (type I). METHODS Sixty-two patients were interviewed shortly after their admission to the hospital (after 3 to 5 days). The current symptoms experienced by the patients were assessed upon admission and again at discharge from the hospital. RESULTS A poorer quality of sleep (higher PSQI scores) (Beta=0.590) was significantly associated with higher mania, whereas the intake of SSRIs (Beta=-5.952) and TCAs (Beta=-8.181) was significantly associated with lower mania. Furthermore, highly significant reductions were reported in the PSQI scores (4.96 vs. 2.75, P<0.001), ISI scores (8.30 vs. 3.45, P<0.001) and YMRS scores (8.60 vs. 3.06, P<0.001) between admission to and discharge from the hospital. CONCLUSION Insomnia in patients with bipolar disorder type I is associated with mania, with a significant reduction of sleep problems seen during a period of approximately 20 days of hospitalization. Further longitudinal studies are needed to confirm the validity of our results and identify the causes. In the meantime, this research recommends a strategy to improve sleeplessness experienced during inter-episode phases may be helpful in preventing manic episodes in BD.

Abstract
In 2020, new guidelines have been published by the European Society of Cardiology including those on non-ST-segment elevation acute coronary syndromes, atrial fibrillation and adult congenital heart disease. Regarding interventional cardiology, POPular TAVI opens the possibility of anti-platelet monotherapy after transcutaneous aortic valve replacement. EMPEROR-Reduced confirms the importance of SGLT2 inhibitors in the treatment of heart failure with reduced ejection fraction. Within the field of imaging, stress MRI has now become the first-line technique for the screening of coronary artery disease, demonstrating an excellent cost-benefit ratio. Finally, renin-angiotensin-aldosterone inhibitors do not appear to increase the risk of an infection by COVID-19.

Abstract
Abstract
Introduction
Stereotactic radio-ablation (STAR) has been recently introduced for the management of ventricular tachycardia (VT) refractory to antiarrhythmic drugs (AADs) and catheter ablation (CA). The incidence and mechanisms of VT recurrences after STAR remain unknown. We report causes of recurrence in patients (pts) after STAR.
Methods
From 09.2017 to 01.2020, 12pts suffering from refractory VT were enrolled. The underlying cardiopathy was ischemic in 3, inflammatory in 3 and idiopathic in 6 pts. Before STAR, an invasive electro-anatomical mapping (Carto3) of the VT substrate (VT-sub) was performed. A mean dose of 22±2Gy was delivered to the VT-sub using the Cyberknife® system.
Results
The ablation volume was 24±7cc and involved the interventricular septum (IVS) in 10. After a median follow-up of 9±7 months, VT burden decreased by 78% (mean value, from 89 to 20 VT/semester). Out of the 12 pts, 9 (75%) presented some form of VT recurrence (table): 1) that spontaneously resolved in 2 pts; 2) remote from the VT-sub in 2 cases; 3) managed with AADs that had failed before STAR in 2 cases; 4) within the treated VT-sub in 3 cases. In the latter 3 cases, one recurrence came from a site adjacent to the circumflex artery (mean dosis 14.4 Gy), and two were located within the treated IVS (one displaying marked fibrosis, and one with sarcoidosis). Only 4/12 (33%) pts required additional CA.
Conclusion
STAR led in our patients to a strong VT burden reduction. Recurrences occurred at sites remote from the irradiated volume, within the IVS or in under-dosed sites adjacent to critical structures.

Abstract
The gene SCN5A encodes the cardiac sodium channel which, through the conduction of Na+ current into the cell, generates the fast upstroke of the action potential of cardiomyocytes. Pathogenic variants of SCN5A have been causally associated to several hereditary cardiac diseases including, among others, Brugada syndrome, congenital long QT syndrome and sinus node dysfunction. Recently, overlap syndromes have been described that are characterized by the simultaneous expression of mixed clinical phenotypes among two or more hereditary cardiac diseases associated to the gene SCN5A (HCD-SCN5A). For this reason, it is time to rethink about HCD-SCN5A as different expressions of the same complex spectrum encompassing multiple clinical phenotypes with pronounced overlaps instead of as distinct clinical entities.

Abstract
Background Liver tumors are subject to motion with respiration, which is typically accounted for by increasing the target volume. The prescription dose is often reduced to keep the mean liver dose under a threshold level to limit the probability of radiation induced liver toxicity. A retrospective planning study was performed to determine the potential clinical gains of removal of respiratory motion from liver SABR treatment volumes, which may be achieved with gating or tumor tracking. Methods Twenty consecutive liver SABR patients were analysed. The treated PTV included the GTV in all phases of respiration (ITV) with a 5 mm margin. The goal prescription was 50Gy/5# (BED 100 Gy10) but was reduced by 2.5 Gy increments to meet liver dose constraints. Elimination of motion was modelled by contouring the GTV in the expiration phase only, with a 5 mm PTV margin. All patients were replanned using the no-motion PTV and tumor dose was escalated to higher prescription levels where feasible given organ-at-risk constraints. For the cohort of patients with metastatic disease, BED gains were correlated to increases in tumour control probability (TCP). The effect of the gradient of the TCP curve on the magnitude of TCP increase was evaluated by repeating the study for an additional prescription structure, 54Gy/3# (BED 151 Gy10). Results Correlation between PTV size and prescribed dose exists; PTVs encompassing < 10% of the liver could receive the highest prescription level. A monotonically increasing correlation (Spearman’s rho 0.771, p = 0.002) between the degree of PTV size reduction and motion vector magnitude was observed for GTV sizes <100cm3. For 11/13 patients initially planned to a decreased prescription, tumor dose escalation was possible (5.4Gy10–21.4Gy10 BED) using the no-motion PTV. Dose escalation in excess of 20 Gy10 increased the associated TCP by 5% or more. A comparison of TCP gains between the two fractionation schedules showed that, for the same patient geometry, the absolute increase in BED was the overarching factor rather than the gradient of the TCP curve. Conclusions In liver SABR treatments unable to be prescribed optimal dose due to exceeding mean liver thresholds, eliminating respiratory motion allowed dose escalation in the majority of patients studied and substantially increased TCP.

Abstract
OBJECTIVES The Hamilton Depression Rating Scale (HDRS) is the most commonly used scale for the evaluation of patients' treatments for depression. Since the HDRS has never been validated in Lebanon to our knowledge, our primary objective, therefore, is to investigate the correlation, sensitivity, specificity, as well as the reliability and the validity of the Hamilton Depression Rating Scale (HDRS) among Lebanese depressed patients. The secondary objective is to identify sociodemographic factors that would be correlated to depression among our sample. METHODS This case-control study, performed between January till May 2017, included 400 patients (200 patients, 200 controls). RESULTS The HDRS scale items converged over a solution of four factors, explaining a total of 58.88% of the variance. A high Cronbach's alpha was found for the full scale (0.862). A stepwise linear regression, using the total HDRS score as continuous variable, showed that a low socioeconomic level, divorced participants and a family history of mental disorders would significantly increase the HDRS total score (Beta=4.278; Beta=5.405; and Beta=3.922) respectively. However, having a university level of education would significantly decrease the HDRS total score (Beta=-4.248, P<0.001). CONCLUSION This study shows that the Arabic version of the HDRS has promising psychometric properties, making it a good tool to use for the diagnosis of patients with depression. Depression recognition and treatment in general practice with the aim of improving patient outcome and reducing health care expenditure, is definitely warranted.

Abstract
The aim of this study is to investigate the effect of three cucurbitacins (Cuc) E, D and I on the bilirubin-albumin binding, both in human serum albumin (HSA) and in plasma. Bilirubin-HSA solution and plasma free of cucurbitacins were prepared as well as others containing serial concentrations of cucurbitacins. The concentration of unbound bilirubin was determined in bilirubin-HSA solution and the direct and total bilirubin concentrations were measured in plasma (with normal or elevated bilirubinemia) by Jendrassik and Grof method. In the conditions we adopted Cuc E and D (to a lesser extent), decreased the levels of unbound bilirubin in bilirubin-HSA solution and decreased direct bilirubin concentration and total bilirubin concentration in plasma in a dose-dependent manner while Cuc I had no effect. The effect of Cuc is related to the presence of native HSA. Thus, when albumin was absent or has been denatured by heating or by urea, Cuc E did not modify bilirubin levels, suggesting that the native structure of albumin is essential for such activity. The interaction of HSA with Cuc E was investigated by fluorescence spectroscopy. Cuc E increased the intrinsic fluorescence of the protein and the magnitude of fluorescence intensity of bilirubin-albumin complex. We concluded that Cuc E and D produced a rearrangement in the structure of albumin, particularly in the domain-II, resulting in an increase in the binding of bilirubin to albumin regardless to whether it's conjugated to glucuronic acid or unconjugated.

Abstract
OBJECTIVES To identify the factors associated with early cardiac catheterization in patients with a non ST-segment elevation acute coronary syndrome. METHODS We analyzed data collected by retrospective chart review for 208 patients presenting at seven French hospitals with an acute coronary syndrome (chest pain at rest within 24 h prior to presentation with positive cardiac markers and/or electrocardiographic changes) between January and March 2005. RESULTS Eighty-seven patients (42%) were first admitted to hospitals with cardiac catheterization facilities. One hundred ten patients (53%, 95% confidence interval [95% CI], 46-60) underwent early cardiac catheterization less than 48 h following presentation. In addition to presentation at hospitals with catheterization facilities, factors independently associated with early catheterization included positive cardiac markers in patients first admitted to hospitals without catheterization facilities (adjusted odds ratio [aOR] 34.5, 95% CI, 4.4-268.0) and diabetes mellitus (aOR, 0.4, 95%CI, 0.2-0.9). With the exception of positive cardiac markers, no risk factors comprising the TIMI risk score were associated with increased odds of early cardiac catheterization. During the index hospital stay, six patients (3%) died, seven patients (3%) had pulmonary edema, three patients (1%) had major or minor bleeding, and none had ST segment elevation myocardial infarction. CONCLUSION Despite the dissemination of international guidelines, the use of early cardiac catheterization remains related to initial presentation at hospitals with catheterization facilities rather than risk assessment in patients with a non ST-segment elevation acute coronary syndrome.

Abstract
PURPOSE To prospectively evaluate the intraocular pressure (IOP) lowering ability, retreatment rate, and complications of transcleral Diode laser cyclophotocoagulation using a higher power setting than what is generally recommended. PATIENTS AND METHODS A total of 36 eyes of thirty six patients with refractory glaucoma, and who fitted our inclusion criteria underwent Diode cyclophotocoagulation. The laser power was set at 2250 mW, with a duration of 2000 ms, and a total number of 28 shots for the first treatment and 20 shots for any consequent one. The patients were followed up for 1 year with the following outcomes being analysed: IOP, visual acuity, change in the number of medications, and complications. RESULTS The mean IOP decrease was 53% (P < 0.05), and 72.2% of the patients maintained an IOP < or =21 mmHg for the whole duration of the study The number of medications necessary to control the pressure, significantly dropped from 2.8 to 0.89 (P < 0.05), and 25% of the patients needed the treatment to be repeated only once. In all, 33% of the patients improved their visual acuity after the treatment, while 22% worsened, and the rest stayed the same. The most common treatment complications were conjunctival injection and corneal oedema, and these were both transient and reversible. CONCLUSION The use of the higher power setting of 2250 mW, resulted in a sustained lower IOP, less use of medications, less need for retreatment, relative preservation of visual acuity, and only reversible complications.

Abstract
We aimed to evaluate exposure to hepatitis B and C viruses [HBV and HBC] and candidate risk factors among the Lebanese population. All individuals presenting to all laboratory units in the country over a 2-week period were asked for a 5-mL whole blood sample and answered a questionnaire addressing risk factors. For individuals under 15 years of age the mother was interviewed. In all, 2893 blood samples were examined. Refusal rate was 2.9%. Exposure to HBV antigen was 18.9%; 1.9% were carriers and acute hepatitis B point prevalence was 0.1%. Exposure to HCV antigen was 0.7%. Exposure to both HBc and HCV antibodies was 0.2%. HBc prevalence increased with age and was higher among men. Significant risk factors included blood transfusion, haemodialysis and gastrointestinal endoscopy.

Abstract
This prospective study evaluated the efficacy of an outpatient management protocol for patients with a gunshot-induced fracture with a stable, nonoperative configuration. Forty-one patients (44 fractures) with a grade I or II open, nonoperative fracture secondary to a low-velocity missile comprised the study population. Patients were treated by a standard protocol, which included 1 g of cefazolin administered in the emergency room and a 7-day course of oral cephalexin. Follow-up visits were performed until complete wound and fracture healing were achieved. Thirty-two (78%) of 41 patients underwent full follow-up. Average follow-up was 5.2 months. One (2.8%) fracture (distal fibula) developed a superficial infection, which responded to an additional week of oral antibiotics, and no patient developed a deep infection. There was 1 delayed union and 2 patients with painful retained shrapnel. These results demonstrate that patients with stable, low-velocity, gunshot-induced fractures can be managed effectively and safely on an outpatient basis using this protocol.

Abstract
The VIPoma syndrome is rare. It is usually caused by a neuroendocrine tumor located in the pancreas. Somatostatin analogs and interferon-a can be helpful in the symptomatic control of the disease, but the efficacy of chemotherapy in metastatic disease is limited. We report the case of a 32-yr-old patient who had a primary intestinal VIPoma with peritoneal carcinomatosis and hepatic metastases. Somatostatin analogs and conventional chemotherapy regimens were not effective on VIPoma syndrome and tumor progression. The combination of 5- fluorouracil and interferon-alpha was associated with a major clinical improvement and tumor regression. Further investigations should evaluate the place of such a combination as a first line treatment for patients with metastatic neuroendocrine tumors.

Abstract
Thyroid function, studied in 36 scleroderma patients revealed 7 abnormal cases: 6 hypothyroid patients secondary to autoimmune thyroiditis and 1 hyperthyroidism secondary to Graves' disease. In the hypothyroid subgroup, 3 cases presented a localized systemic sclerosis and the 3 others presented a diffuse systemic sclerosis; Sjögren syndrome was found in 2 of these patients. The hyperthyroid patient presented a diffuse systemic sclerosis. Because of the association between scleroderma and thyroid diseases, we suggest to perform thyroid screening regularly for all patients with systemic sclerosis.

Abstract
Plasma concentrations and urinary excretion of DTZ and its metabolites were determined in 20 healthy volunteers (10 males and 10 females) after they had each been given a single oral 90 mg dose of DTZ. DTZ and six of its metabolites which included N-monodesmethyl DTZ (MA), deacetyl DTZ (M1), deacetyl N-monodesmethyl DTZ (M2), deacetyl O-desmethyl DTZ (M4) and deacetyl DTZ N-oxide (M1NO) and deacetyl N,O-didesmethyl DTZ (M6), were determined by a sensitive and specific HPLC assay. The major metabolites measurable in the plasma of all the volunteers were MA, M1, and M2. The terminal half-lives (t1/2) of M1 and M2 were considerably longer than those of DTZ and MA. Less than 5% of the dose was excreted as unchanged DTZ in the urine over the 24 h period. The major urinary metabolite was MA, followed by M6, M2, and then M1. Except for the urinary excretion of M4 there were no statistically significant differences in any of the pharmacokinetic parameters between the males and the females. The mean 24 h urinary recovery of M4 was higher in the males than in the females (P < 0.05). However there were large inter-individual variations in the plasma concentrations and urinary excretion of DTZ and its metabolites with some parameters differing by more than 20-fold. In addition, O-desmethyl DTZ (Mx) and N,O-didesmethyl DTZ (MB) were identified as two other major urinary metabolites.
