Bumetanide
It works by inhibiting the sodium-potassium-chloride cotransporter in the thick ascending limb of the loop of Henle, leading to increased urine output and reduced fluid buildup.
Bumetanide is known for its rapid onset of action and high potency, making it a valuable tool for managing acute and chronic fluid imbalances.
Researchers studying the pharmacology, clinical applications, and therapeutic potential of bumetanide can leverage PubCompare.ai's AI-driven optimization platform to streamline their research, locate the best protocols, and ensure reproducable and accurate results.

We used the perforated patch-clamp technique in every recording. We used gramicidin D (50 μg/mL, Sigma) to establish access resistances between 30–40 MΩ throughout the recording period. We performed the recordings at 34°C and applied all compounds locally to neurons by a gravity-fed three-barreled pipette driven by a fast-step motor (Warner Instruments). The recording pipette saline contained (in mM) 140 KCl and 10 HEPES, pH 7.4 KOH. Bath saline contained (in mM) 140 NaCl, 4.7 KCl, 2.5 CaCl2, 1.2 MgCl2, 10 HEPES, 11 glucose, pH 7.4 NaOH., We performed all the experiments for the determination of EGABA values in the presence of TTX (500 nM), DNQX (20 μM), and AP5 (50 μM) to block voltage-gated sodium channels, AMPA receptors, and NMDA receptors, respectively. However, we applied glutamate (20 μM) for 2 min without these antagonists and it was always applied in I=0 mode, never in voltage-clamp mode. After glutamate treatment, we immediately re-exposed neurons to the ion channel blocker/antagonists for 8 min prior to recording GABA-evoked currents. For the I–V experiments, we voltage-clamped neurons at specified holding potentials (20 mV increments in either direction beginning at −60 mV) for 30 s prior to the application of GABA. We performed the experiments testing furosemide inhibition, the role of excitatory GABA, and the time-course of EGABA shifts on separate groups of neurons. We employed voltage-ramp protocols prior to glutamate application to determine the reversal potential of leak currents for a secondary assessment of resting membrane potential. These data revealed our I=0 measurements of resting membrane potential were accurate to within 5 mV (data not shown). Furosemide, bumetanide, and okadaic acid were dissolved in DMSO (0.1% final concentration), all other compounds were dissolved in deionized H2O. We used a three-barreled (0.7 mm diameter per barrel) glass perfusion pipette (Warner Instruments) placed just above the target neuron to apply all agonists, antagonists, compounds, and control saline. We applied these solutions through the perfusion pipette at a rate of 0.5 mL/min and we used a computer controlled perfusion fast-step device (Warner Instruments) to ensure rapid and complete exchange of solutions. We obtained all data using an Axopatch 200B amplifier and pClamp 8 software (Axon Instruments). Data were recorded onto a personal computer for offline analysis using Clampfit. All records were filtered at 2 kHz and digitized at 10 kHz.

were used for all of the animal studies performed, which were purchased from the
Institute of Rehabilitation Medicine China Rehabilitation Science Institute
(Beijing, China). They were kept under standard conditions maintained at 22 ±
2°C, 55% ± 10% humidity, 12:12 h light/dark cycle with free access to food and
water. All animals were randomly divided into three groups for the current study
(sham, SCI, and bumetanide (BU) groups). Pharmacological studies involving BU
group were conducted with SCI animals. At the end of experiments and before
tissue harvesting, rats were deeply anesthetized by intraperitoneal injection of
10% chloral hydrate (mg kg−1).

Resistant hypertension is defined as having an office BP of > 140 mmHg (systolic) and/or 90 mmHg (diastolic) or, if available, a 24-h ambulatory blood pressure measurement (24-h ABPM) daytime BP of > 135 mmHg and/or 85 mmHg despite a medication regimen of AHDs in the maximal tolerable dose of at least three AHDs from different drug classes, including a diuretic, or at least four AHDs from different drug classes.
