The effect of indomethacin on renal function
Acta Physiologica Academiae Scientiarum Hungaricae
|January 1, 1980
Summary
Indomethacin
Area of Science:
- Nephrology
- Renal Physiology
- Pharmacology
Background:
- Prostaglandins (PGs) are implicated in kidney function, potentially acting as natriuretic hormones.
- Extracellular fluid volume expansion typically induces natriuresis, a process possibly mediated by PGs.
Purpose of the Study:
- To investigate the role of prostaglandins in renal function and their interaction with indomethacin.
- To elucidate the mechanisms by which prostaglandins influence salt and water excretion.
Main Methods:
- Literature review and experimental data analysis.
- Volume expansion in dogs and rabbits under Nembutal anesthesia.
- Administration of indomethacin to inhibit prostaglandin synthesis.
Main Results:
- Indomethacin pretreatment significantly reduced natriuresis during volume expansion in dogs.
- Indomethacin pretreatment enhanced the diuretic and natriuretic effects of volume expansion in rabbits.
- Data suggest intrarenal PGs modulate renal vascular resistance and regulate salt/water balance.
Conclusions:
- Intrarenal prostaglandins play a crucial role in adjusting renal vascular resistance.
- Prostaglandins are physiologically important in regulating renal salt and water excretion.
