Where to Buy Lasix 20mg: Vendor Comparison & Research Info

Lasix (Furosemide) is a potent loop diuretic investigated in pharmacological and biomedical research involving renal physiology, electrolyte transport, fluid balance, cardiovascular biology, and diuretic mechanisms. Its well-characterized action on the nephron makes it an important research compound for studying sodium and chloride reabsorption and regulation of extracellular fluid volume.

Overview

Furosemide acts primarily within the thick ascending limb of the loop of Henle, where it inhibits the sodium-potassium-chloride cotransporter (NKCC2). This reduces the reabsorption of sodium and chloride and increases the renal excretion of water and electrolytes.

Because of its pronounced effects on renal electrolyte handling, furosemide is widely studied in experimental models of fluid regulation, kidney function, hypertension, edema, and cardiovascular physiology.

Molecular Characteristics

• Active Ingredient: Furosemide

• Common Brand: Lasix

• Chemical Class: Loop diuretic

• Molecular Formula: C₁₂H₁₁ClN₂O₅S

• Molecular Weight: 330.74 g/mol

• CAS Number: 54-31-9

• Form: Pharmaceutical tablet

Research Applications

Furosemide is investigated across several areas of biomedical research, including:

• Renal physiology and kidney function

• Sodium and chloride transport

• Electrolyte homeostasis

• Fluid-volume regulation

• Cardiovascular physiology

• Hypertension research

• Edema and fluid-retention models

• Pharmacokinetics and pharmacodynamics

• Renal transporter biology

Mechanism of Action

Furosemide primarily targets the Na⁺-K⁺-2Cl⁻ cotransporter (NKCC2) in the thick ascending limb of the nephron. Blocking this transporter reduces sodium and chloride reabsorption and alters the osmotic gradient responsible for concentrating urine.

The resulting increase in renal electrolyte and water excretion provides researchers with a useful model for examining how changes in sodium handling influence blood volume, extracellular fluid balance, and cardiovascular function.

Key Research Mechanisms

NKCC2 Inhibition:
Researchers use furosemide to investigate sodium, potassium, and chloride transport within the renal tubule.

Electrolyte Regulation:
Experimental models can evaluate how altered renal electrolyte excretion affects systemic homeostasis.

Renal Hemodynamics:
Furosemide provides a model for studying relationships between kidney function, fluid volume, and cardiovascular physiology.

Fluid Balance:
Its pronounced diuretic activity makes it useful for investigating mechanisms governing extracellular fluid volume and water distribution.

Primary Research Areas

1. Renal Physiology

Furosemide is commonly used as a pharmacological tool for examining renal tubular transport, nephron function, and electrolyte handling.

2. Cardiovascular Research

Changes in sodium and fluid balance can influence cardiovascular physiology. Research models may therefore investigate furosemide's relationship with circulating volume and cardiac function.

3. Electrolyte Homeostasis

Researchers can use furosemide to study changes in sodium, potassium, chloride, and other electrolyte concentrations under controlled conditions.

4. Pharmacological Research

Because furosemide has a well-characterized mechanism and established pharmacokinetic properties, it can serve as a reference compound in studies evaluating diuretic activity and renal drug transport.

Analytical Testing

Research-grade furosemide can be characterized using established analytical techniques, including:

• High-Performance Liquid Chromatography (HPLC)

• Liquid Chromatography–Mass Spectrometry (LC-MS)

• Spectroscopic analysis

• Identity and purity testing

• Stability testing

These methods help confirm chemical identity, assess purity, and monitor formulation stability.
