PHARMACOLOGY 
PHARMACODYNAMICS 
Indapamide is an oral antihypertensive agent.  The
mechanism whereby indapamide exerts its 
antihypertensive action has not been completely elucidated; both vascular and renal actions have been 
implicated. 

At a dose of 2.5  mg the renal effects of indapamide are
minimal and the antihypertensive effect of 
indapamide has been attributed to a reduction in vascular reactivity to pressor amines.  The finding that 
indapamide retains its antihypertensive activity in
functionally anephric patients lends support to the 
hypothesis. 

The renal site of action of indapamide is the proximal segment of the
distal tubule.  Indapamide appears 
to have natriuretic properties (sodium and chloride being
excreted in equivalent amounts) with less effect 
on kaliuresis or uric acid excretion.  Only at doses greater than 2.5 mg/day is an appreciable increase in 
urinary volume observed in humans.  No significant changes in
plasma sodium levels have been 
observed in clinical studies.  Significant hypokalaemia (plasma
potassium <  3.2 mmol/L�
