Medical uses

High blood pressure

Administration

One tablet daily, preferably to be taken in the morning and before a meal.

Elderly: Normal dosage.

Kidney failure: Creatinine clearance (CrCl) >30 mL/min: no dosage modification. If CrCl <30 mL/min, treatment is contraindicated.

Contraindications

Absolute contraindications to taking perindopril/indapamide include a known allergy to perindopril, indapamide, or sulfonamides; history of Quincke's edema linked to previous ACE inhibitor therapy; end-stage kidney disease; serious liver disease; high levels of potassium in the blood; pregnancy; and lactation.

Relative contraindications to using this medication include combination therapy with lithium, potassium salts, potassium-sparing diuretics, and certain medicines which can cause abnormal heart rhythms.

Side effects

Side effects of perindopril/indapamide may include weakness, dizziness, headache, mood swings and/or sleep disturbances. Additionally, cramps, low blood pressure, allergic reactions, skin rashes, gastrointestinal disorders, dry cough, erectile dysfunctions, dry mouth, and a risk of dehydration in the elderly and in people who have congestive heart failure.

Immunosuppressed patients. Hemodialysis: risk of anaphylactoid reaction during hemodialysis with polyacrylonitrile membranes. Liver impairment.

Caution is recommended when prescribing perindopril/indapamide to people with electrolyte disorders, diabetes, gout, low blood pressure, or strict sodium-free diets, heart or kidney failure, atherosclerosis, renal artery stenosis, and in elderly people.

Pharmacology

Using a fixed combination of an ACE inhibitor and a chlorosulfamoyl diuretic leads to additive synergy of the antihypertensive effects of the two constituents. Its pharmacological properties are derived from those of each of the components taken separately, in addition to those due to the additive synergistic action of the two constituents, when combined, on vascular endothelium, arteriolocapillary microcirculation, and the target organs of hypertension.

Drug interactions

Not recommended: combinations with lithium, potassium-sparing diuretics, potassium (salts), antiarrhythmic drugs which can cause torsades de pointes, anesthetic drugs, cytostatics or immunosuppressive agents.
