6. Contents of pack and other information
Losartan Potassium/Hydrochlorothiadise tablets (from here on called Losartan
HCT tablets) are a combination of an angiotensin II receptor antagonist (losartan)
and a diuretic (hydrochlorothiazide). Angiotensin II is a substance produced in
the body which binds to receptors in blood vessels, causing them to tighten.
This results in an increase in blood pressure. Losartan prevents the binding of
angiotensin II to these receptors, causing the blood vessels to relax which in
turn lowers the blood pressure. Hydrochlorothiazide works by making the
kidneys pass more water and salt. This also helps to reduce blood pressure.
Losartan HCT tablets are indicated for the treatment of essential hypertension
(high blood pressure).
Do not take Losartan HCT tablets if you:
- are allergic (hypersensitive) to losartan, hydrochlorothiazide or to any of the
other ingredients listed in section 6.
- are allergic (hypersensitive) to other sulfonamide-derived substances (e.g.
other thiazides, some antibacterial drugs such as co-trimoxazole.) Ask your
doctor if you are not sure.
- suffer from high calcium, low potassium or low sodium levels in your blood
that does not respond to treatment.
- have severely impaired liver function or blockage of bile ducts.
- are suffering from gout.
- are more than 3 months pregnant (it is also better to avoid Losartan HCT
tablets in early pregnancy. See ‘Pregnancy and Breastfeeding’)
- have severely impaired kidney function or your kidneys are not producing
any urine.
