Differences between Diovan and Valsartan What are generics? Generic drugs, marketed without brand names, contain the exact same active ingredients used in their brand-name counterparts, but cost significantly less. The drugs are required to meet US Food and Drug Administration (FDA) standards for safety, purity and effectiveness.

Differences between Diovan and Valsartan

Diovan (generic name Valsartan) is intended for the treatment of hypertension and cardiac failure. These are increasingly common conditions, which affect even young people.

Hypertension has been nicknamed ‘silent killer’ because lots of people develop dangerously high blood pressure without even realizing it. In other words, people, who have it, feel well and do not see the damage being done to the body. The heart has to work much harder, and one day it may just tear off, which may cause a heart attack or myocardial infarction.

With blood pressure getting too high, there is much more work for your blood vessels that they can handle. As the condition progresses, the vessels (especially capillaries) may fail to withstand the workload and collapse, and this may occur in any part of the body. A condition, when a tiny capillary collapses in the brain, is called a ‘stroke’, and it may be crippling or fatal.

How Diovan and Valsartan Work

Both medications are used to reduce blood pressure in patients dealing with severe cases of hypertonia. Diovan and Valsartan are angiotensin II receptor blockers, which inhibit angiotensin – a hormone, which increases blood pressure when it gets too low. The drugs help blood vessels to dilate, improve the blood flow and control blood pressure, preventing it from hitting critical levels.

Both come in tablets, which can contain 40 mg, 80 mg, 160 mg, and 320 mg of active ingredient. Also, the drug is available in a liquid form. It should be taken orally in strict accordance with the prescription. Dosage depends on the severity of hypertension and individual response to valsartan.

Most doctors advise taking one or two pills each day, with or without food and at a fixed time. Taking a double dose to compensate for a missed one is forbidden because it can lead to overdose.

Some patients develop side effects. Although they rarely go beyond minor, you should contact your doctor immediately if you have any of the following:

  • Headache;
  • Drowsiness;
  • Dizziness;
  • Fatigue;
  • Nasal and respiratory disorders;
  • Nausea;
  • Diarrhea;
  • Itching;
  • Swelling of the face;
  • Difficulty breathing;
  • Vomiting.

Some of them may be the signs of anaphylactic reactions. If so, the use of the drug must be stopped. Moreover, both Diovan and Valsartan should not be administered during pregnancy or breastfeeding.

Brand vs. Generic – Similarities and Differences

Valsartan is a generic version of Diovan. Generic medicines have the same amount of the active ingredient as the brand ones, so the effect is the same. However, generics are often much cheaper than their brand counterparts. This happens because manufacturers do not have to invest in research, marketing, and promotion. They switch to production of generics when patents are nearly expired. In fact, this requires an FDA (Food and Drug Administration) permission.

Studies have shown that patients who use Diovan and Valsartan demonstrate the same (or almost the same) blood levels. Generics are not much different from brand drugs. And neither does Valsartan differ from Diovan. If there is something that makes them different, it is inactive ingredients (preservatives, flavoring agents, dyes, etc.) and the appearance. Also, the manufacturing process is usually different. Some laws require manufacturers of generics to make their medicines are distinguishable from brand drugs.


As follows from the above, Diovan and Valsartan have one thing in common, and it is quite decisive – the amount of the active ingredient, which produces the effect needed for successful treatment of infections.
