Rabbit left ventricular cardiomyocytes were isolated enzymatically as prescribed previously.21 (link) Only cardiomyocytes with smooth and glossy edges and surfaces, clear transverse striations, and that could be stably voltage-clamped for 8 min without significant contraction were used. Seal resistance was above 1GΩ with less than 10 % variability. Currents were obtained with a patch-clamp amplifier (EPC-10, Heka Electronic, Lambrecht, Pfalz, Germany), filtered at 1 kHz and digitized at 10 kHz. During recording of late INa, the bath solution contained (in mmol/L):135 NaCl, 5.4 CsCl2, 1.8 CaCl2, 1 MgCl2, 0.3 BaCl2, 0.33 NaH2PO4, 10 glucose, 10 HEPES, 0.001 nicardipine, pH 7.3. The patch pipette solution contained (in mmol/L):120 CsCl2, 1.0 CaCl2, 5 MgCl2, 5 Na2ATP, 10 TEACl, 11 EGTA, 10 HEPES (pH 7.3, adjusted with CsOH). All experiments were carried out at a temperature of 23±1 °C.
To elicit a late INa in a single cell, twenty 300-ms depolarizing pulses to -20 mV from a holding potential of -90 mV were applied at CLs of 500, 667, 1000, 2000 and 4000 ms using a serial repeated-measurement protocol, with 3 min between each change of stimulation CL, during which membrane potential was held at -90 mV. In cardiomyocytes isolated from 8 rabbit hearts, the amplitude of late INa was measured at 200 ms after initiation of the depolarization step before (control, no drug) and 3 min after exposure of a myocyte to 1 and 4 μmol/L TTX, respectively.

The goal of treatment was to reduce and maintain the hourly minimum systolic blood pressure in the range of 140 to 179 mm Hg in the standard-treatment group and in the range of 110 to 139 mm Hg in the intensive-treatment group throughout the period of 24 hours after randomization. Before randomization, intravenous anti-hypertensive medication, including nicardipine, could be administered to lower the systolic blood pressure to less than 180 mm Hg,12 (link) but patients were not eligible if the systolic blood pressure was lowered to less than 140 mm Hg. After randomization, nicardipine, administered by intravenous infusion, was the first-line antihypertensive agent and was initiated at a dose of 5 mg per hour, which was then increased by 2.5 mg per hour every 15 minutes as needed, up to a maximum dose of 15 mg per hour. If the systolic blood-pressure level was higher than the target, despite infusion of the maximum dose of nicardipine for 30 minutes, a prespecified second agent, intravenous labetalol, was used. In countries where labetalol was not available, intravenous diltiazem or urapidil was used. Additional care was based on the best available evidence15 (link) and the guidelines from the American Stroke Association Stroke Council12 (link) and the European Stroke Initiative Writing Committee.16 (link)We assessed the success, or lack thereof, of the reduction in the systolic blood-pressure level. Primary treatment failure was defined as not reaching the target systolic blood pressure of less than 140 mm Hg in the intensive-treatment group and less than 180 mm Hg in the standard-treatment group within 2 hours after randomization. Secondary treatment failure was defined as the hourly minimum systolic blood pressure remaining higher than the upper limit of the target range for 2 consecutive hours during the period of 2 to 24 hours after randomization. No effort was made to conceal the treatment assignment from the participants or treating physicians.

Cover glasses that contained glomeruli were placed into a perfusion chamber
mounted on an inverted Nikon Ti-S microscope and superfused with a physiologic saline
solution (pH 7.4). Single-channel current data were acquired as described
previously.19 (link),20 (link) After a high resistance seal was obtained, cell-attached
recording was performed immediately. The membrane resistance was monitored regularly to
ensure the quality of recording. For measurements of acute effect only one experiment was
performed per dish to avoid any possibility of examining cells whose properties might have
been altered by extended exposure to Ang II. The recordings were made in symmetric
chloride solutions. The bath solution consisted of 126 NaCl, 1 CaCl2, 10 HEPES,
2 MgCl2, 10 glucose, pH 7.4. The pipette solution contained 126 NaCl, 1.5
CaCl2, 10 HEPES, 10 glucose; pH7.4; plus added directly before the
patch-clamp experiments were 100 µM niflumic acid or DIDS (to block
Ca2+-activated Cl channels), 10 mM TEA (to inhibit
large-conductance Ca2+-dependent K+ channel), 10 nM iberiotoxin (to
block Ca2+-activated K+ channels), 10 µM nicardipine (to
block N-type Ca2+ channels). During the patch-clamp measurements in the
single-channel mode the activity of the ion channels was first monitored in response to
the potential applied in steps of 10 or 20 mV in the range of – 90 mV to + 60 mV
in order to estimate the channel’s conductance and I-V relationship. After that,
the voltage was clamped at – 60 mV and the channels’ activity was recorded
for several minutes before the drugs were applied.

The US Food and Drug Administration (FDA) adverse event reporting system (FAERS) is an SRS and the largest and best-known database worldwide. The regulatory authority in Japan, the Pharmaceuticals and Medical Devices Agency (PMDA), controls the SRS of the JADER database. Adverse events recorded in the FAERS database from January 2004 to June 2014 were downloaded from the FDA website (http://www.fda.gov). Relevant information from the JADER database from April 2004 to November 2016 was downloaded from the PMDA website (http://www.pmda.go.jp). We constructed a database that integrated each FAERS and JADER dataset using the FileMaker Pro 13 (FileMaker Inc.). For duplicate entries, we followed the FDA recommendation (http://www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Surveillance/AdverseDrugEffects), and adopted the most recent case number to identify duplicate patient reports and excluded them from the analysis.
We analyzed four immunosuppressants (CsA, everolimus, sirolimus, and mycophenolate mofetil), four calcium channel blockers (amlodipine, benidipine, nicardipine and nifedipine), and 11 anticonvulsants (carbamazepine, clobazam, diazepam, gabapentin, levetiracetam, phenobarbital, phenytoin, primidone, topiramate, valproic acid, and zonisamide). For drug definitions, we used both the general and brand names based on the DrugBank 3.0 and 4.0 (Table 1). Drugs in the FAERS were classified into four categories: Primary Suspect drug (PS), Secondary Suspect drug (SS), Concomitant (C), and Interacting (I); according to their anticipated degree of involvement in adverse events. The analysis was restricted to reports where drugs were recorded as PS and SS in the FAERS database. In the “drug information” table of the JADER database, each drug was assigned a code according to its association with adverse drug reactions: “suspected drug,” “concomitant drug,” or “interacting drug.” The analysis was restricted to reports where drugs were recorded as “suspected drugs” in the JADER database.

Retention times of the analytes were measured with Shimadzu HPLC system on the CHIRALPAK®HAS stationary phase (50 × 3 mm, 5 μm, Chiral Technologies, DAICEL Group, Europe SAS, France). The mobile phase A consisted of 50 mM aqueous ammonium acetate buffer (pH 7.4) and phase B of 2-propanol according to Valko et al.65 (link) Analysis was performed at prolonged 1 mL min−1 flow rate in the linear gradient. Retention capacity factors (k′) were calculated by using DMSO or a substance with 0% HAS binding for systems' dead time (Rt0). The system was calibrated by injecting the reference compounds: acetylsalicylic acid (CAS 69-72-7), betamethasone (CAS 378-44-9), budesonide (CAS 5133-22-3), carbamazepine (CAS 298-46-4), cimetidine (CAS 51481-61-9), ciprofloxacin (CAS 85721-33-1), indomethacin (CAS 53-86-1), isoniazid (CAS 54-85-3), metronidazole (CAS 443-48-1), nicardipine (CAS 55985-32-5), nizatidine (CAS 76963-41-2) and warfarin (CAS 81-81-2) obtained from Sigma-Aldrich, diclofenac (CAS 15307-86-5) from EMD Chemicals Inc., flumazenil (CAS 78755-81-4) from ABX and ketoprofen (CAS 22071-15-4) from LKT Labs. The logarithmic capacity factors of the references' Rt (log(k′)) on the HSA column were plotted against the %PPB values from literature. The slope and the intercept were used to convert the log(k′) of the compounds (6a, c, f, h, m–o) to %PPB using the regression equation.66 (link)

The collection time of the plasma sample included data from before administration of bepridil to up to 6 h after administration. To assess risk factors for achieving plasma bepridil concentrations ≥800 ng/mL at steady state, the eligible patients were divided into two groups based on their bepridil concentrations: ≥800 ng/mL and < 800 ng/mL.
The C/D ratio was calculated using the following equation:
C/D ratio of bepridil = plasma concentration of bepridil (ng/mL) / dose of bepridil (mg/day/kg body weight).
In this study, we defined the polypharmacy group as those who use six or more drugs, whereas the non-polypharmacy group was those who took fewer than six drugs. The relationship between plasma bepridil concentrations ≥800 ng/mL and baseline characteristics, including sex, age, height, body weight, body mass index, serum creatinine, creatinine clearance (Ccr), number of concomitant drugs used, typical inducers of CYPs (phenytoin, carbamazepine, phenobarbital, and rifampicin) [15 (link)], typical inhibitors of CYPs (erythromycin, clarithromycin, protease inhibitors, and azole antifungals) [15 (link)], aprindine, a competitive inhibitor of CYP2D6 [12 (link)], typical inhibitor of P-gp (amiodarone, diltiazem, nicardipine, nifedipine, propranolol, quinidine, cyclosporin, and tacrolimus) [16 (link)–18 (link)], and left ventricular ejection fraction (LVEF), were examined. LVEF was measured using echocardiographic equipment provided at each hospital. Ccr was estimated using the Cockcroft–Gault formula [19 (link)].
The patient’s medical history and duration of bepridil treatment were collected from medical records.

The surgical procedure was performed under general anesthesia. The ECG, heart rate, arterial blood pressure, SpO2, urine volume, end-tidal carbon dioxide pressure (ETCO2), and depth of anesthesia were measured continuously upon entering the operation room for all patients. According to the results of blood gas analysis and gas monitoring, the respiratory rate or tidal volume was adjusted to maintain ETCO2 at 35 ~ 45 mmHg. Intraoperative heat preservation treatment was performed as follows: the body temperature was maintained at 36 ~ 37 ℃. If the patient’s blood pressure was 30% lower than the blood pressure base value or systolic blood pressure was lower than 80 mmHg, an intravenous pump with a small dose of norepinephrine (0.2 ~ 0.4 µg kg−1 h−1) was used. Nicardipine was intravenously injected at 10 µg kg−1 to maintain intraoperative blood pressure within the normal range if blood pressure was 30% higher than the base value or systolic pressure was higher than 160 mmHg. When the patient’s heart rate was lower than 50 beats h−1, atropine was intravenously injected at 0.5 µg kg−1, and when the heart rate was higher than 100 beats h−1, 0.5 mg kg−1 esmolol was slowly injected intravenously. If the intraoperative COP was < 20 mmHg, furosemide 5 mg was intravenously injected.

After entry to the operating room, HR, BP, and peripheral oxygen saturation were recorded for all patients; subsequently, dexamethasone 0.1 mg/kg and glycopyrrolate 0.005 mg/kg were administered. After pre-oxygenation, propofol 2 mg/kg and rocuronium 0.8 mg/kg were administered. The anesthesia was maintained with desflurane and was adjusted according to the bispectral index (BIS) level goal, which is from 30 to 60.
In the case of the T group, the Ce of remifentanil before intubation was set to 5.0–7.0 ng/mL using the syringe pump with a Minto model (Orchestra® Base Primea, Fresenius Kabi, VL, France) [17 (link)]. During surgery, the patients’ BP and HR were monitored, and the Ce of remifentanil was adjusted within the range of 1.0–3.0 ng/mL. In the M group, 0.7–1 µg/kg of remifentanil was administered before intubation using an infusion pump (Terufusion® Infusion Pump, Terumo, Tokyo, Japan). During surgery, remifentanil was titrated within the range of 0.05–0.2 µg/min/kg against HR and BP within a 20% range of baseline measurements. In both groups, if vital signs could not be controlled by remifentanil alone, a vasoconstrictor (phenylephrine, 50 µg) or vasodilator (nicardipine, 500 µg) was administered.
Remifentanil was discontinued during skin closure, and desflurane was discontinued when the position was changed from lithotomy to supine after surgery, and glycopyrrolate 0.005 mg/kg and pyridostigmine 0.25 mg/kg were administered as reversal agents of neuromuscular blockers. At the end of surgery, fentanyl-based (17.5 µg/kg) intravenous patient-controlled analgesia was administered to all of the participants until POD2. Additional opioids or analgesics were administered when patients complained of pain with an NRS pain score of ≥3 or if the patient required analgesics. In the PACU, fentanyl was administered as a bolus dose of 1 µg/kg. On POD1, intravenous acetaminophen 750 mg and per os ibuprofen 200 mg were used, and on POD2, ibuprofen was administered alone.
