Tamarind and Sitaxsentan sodium

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Sitaxsentan sodium and Tamarind in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Sitaxsentan sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sitaxsentan sodium is filed under 4 classifications — including cytochrome p450 2c9 (cyp2c9) inhibitors, antihypertensive drugs, hepatotoxic drugs. Tamarind has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), aspirin (moderate) and ibuprofen (advil, others) (moderate) — and none of Sitaxsentan sodium’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

From our pharmacist’s overview on the Sitaxsentan sodium page

“Sitaxsentan (Thelin) treats pulmonary arterial hypertension and carries a well known liver warning of its own, which is exactly why I read this list of 173 interacting supplements with genuine concern rather than a shrug. Most entries, 119 of them, either add to its blood pressure lowering effect or work against it, but the group I wou…”

About Tamarind

What is Tamarind?

  • Constipation and digestive upset
  • Culinary flavoring
  • Fever and sore throat
  • Antioxidant support
  • Traditional wound or skin care

Tamarind is a tangy tropical fruit widely used in cooking and traditional medicine, mainly for digestion and as a mild laxative. While it is a nutritious food, strong human evidence for most of its medicinal claims is limited, so use it mainly as a food and talk to your pharmacist before using concentrated supplements.

Tamarindus indica · Fabaceae · Fruit pulp, seeds, leaves, and bark · Fruit pulp, paste, juice, candy, capsules, powder, and extracts

An interaction check asks whether these two react with each other — it does not ask whether Tamarind is a good idea for someone in your situation. Here is what our Tamarind record says about it on its own.

Tamarind: dosing

There is no official, standardized medicinal dose for tamarind. As a food, people eat it in the amounts found in recipes, drinks, or candies, which is generally fine.For supplements such as capsules, powders, or extracts, the best approach is to follow the directions on the product label.
