Interaction Details
Losartan Potassium is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
Puravive contains Panax ginseng. Panax ginseng has the potential to affect the breakdown of drugs that are metabolized by an enzyme called CYP3A4. One example of such a drug is imatinib. There was a case where imatinib was thought to have caused liver damage, and it was believed that this might have been due to Panax ginseng inhibiting CYP3A4, which is involved in imatinib's metabolism (https://pubmed.ncbi.nlm.nih.gov/20332334/). On the other hand, Panax ginseng has been found to increase the breakdown of another drug called midazolam, which is also metabolized by CYP3A4 (https://pubmed.ncbi.nlm.nih.gov/21646440/), suggesting Panax ginseng induces CYP3A4 in some cases (i.e., makes more potent). Given these contradictory findings, it is important to use Panax ginseng cautiously if you are taking medications that are metabolized by CYP3A4, as the interaction between Panax ginseng and these drugs is not fully understood.

Interaction Details
Losartan Potassium is classified as belonging to the following category: Antihypertensive Drugs
Puravive contains quercetin, which has been found to slightly reduce blood pressure in individuals with mild hypertension (https://pubmed.ncbi.nlm.nih.gov/17951477/). There is a theoretical possibility that it could enhance the blood pressure-lowering effects of antihypertensive medications.

Interaction Details
Losartan Potassium is classified as belonging to the following category: Cytochrome P450 2C9 (Cyp2C9) Substrates
Puravive contains quercetin, which has been shown in studies to mildly inhibit the CYP2C9 metabolizing enzyme. This inhibition could potentially increase the risk of side effects from drugs. A small clinical trial with healthy volunteers found that taking 500 mg of quercetin twice daily for 10 days before using diclofenac, a drug metabolized by CYP2C9, increased diclofenac plasma levels by 75% and extended its half-life by 32.5% (source: https://pubmed.ncbi.nlm.nih.gov/29168292/). Combining quercetin with drugs metabolized by CYP2C9 could increase the risk of side effects, so caution is advised.

Puravive Overview

Losartan Potassium Overview
-
Losartan is used alone or in combination with other medications to treat high blood pressure. Losartan is also used to decrease the risk of stroke in people who have high blood pressure and a heart condition called left ventricular hypertrophy (enlargement of the walls of the left side of the heart). Losartan may not decrease the risk of stroke in African Americans who have these conditions. This medication is also used to treat kidney disease in people who have type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood) and high blood pressure. Losartan is in a class of medications called angiotensin II receptor antagonists. It works by blocking the action of certain natural substances that tighten the blood vessels, allowing the blood to flow more smoothly and the heart to pump more efficiently.
-
High blood pressure is a common condition, and when not treated it can cause damage to the brain, heart, blood vessels, kidneys, and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
