This medication belongs to the group of drug known as Angiotensin receptor blocker or ARB mainly prescribed to treat high blood pressure. High blood pressure is a common condition that affects many people. Without treatment, hypertension or high blood pressure can lead to grave health conditions like stroke, heart failure, vision loss, kidney disease and many others. Causes of high blood pressure include unhealthy lifestyle such as being overweight, poor diet, smoking, drinking of alcoholic beverages and stress. Other causes are health conditions like diabetes, pregnancy and sleep apnea.
Losartan works by blocking the angiotensin II receptors and by preventing the action of angiotensin II hormones in the body. Angiotensin II is a hormone involved in regulating the fluid balance in the blood and blood pressure. It works in two ways both of which increases the blood pressure in the blood:
- Causing the blood vessels to constrict and to become narrow.
- Reduces the amount of water and salt that the kidneys filter out from the blood.
Blocking the action of angiotensin II allows the blood vessels to widen. At the same time, it allows the kidney to filter out more fluid in the blood by the kidney which helps in lowering the blood pressure. Lowering the blood pressure also makes it easier for the heart to pump blood around the body which helps improve the symptoms of heart failure such as angina pectoris. Since it’s a combination medication, Losartan potassium can help protect the kidney and slow down kidney disease progression.
Losartan potassium is approved by the US Food and Drug Authority in treating a high blood pressure since 1995. It’s listed as one of the most essential medicines by the World Health Organization or WHO and is considered as one of the safest and most effective medications necessary in a healthcare system. An as ARB, Losartan is recommended as first-line treatment for people with high blood pressure who are under 55 years of age who can’t tolerate ACE inhibitors.
