Lotus and Treprostinil (Inh)

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Treprostinil (Inh)

Treprostinil (Inh) falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Lotus interacts with.

Theoretically, concurrent use of lotus with other antiplatelet drugs might reduce platelet aggregation and increase the risk of bleeding.
Neferine and isoliensinine, constituents of lotus, have been shown to inhibit platelet aggregation, in vitro. These constituents can inhibit the production of pro-aggregating factors like prostaglandins.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the connection worth knowing about. Inhaled treprostinil (Tyvaso) does more than relax the blood vessels in your lungs, it also makes your platelets a little less sticky, which slightly lowers your body's ability to form clots. Lotus contains natural compounds (neferine and isoliensinine) that lab studies suggest may do a similar thing. Put them together and, in theory, you could tip a bit further toward easy bruising or bleeding, like nosebleeds, bleeding gums, or a cut that's slow to stop.

I want to be honest about the strength of this though. It's only theoretical, based on test-tube research, not real people taking both. Everyday lotus in food is very unlikely to matter. Concentrated lotus supplements are the bigger question mark, so run those by your pharmacist or doctor first.

From our pharmacist’s overview on the Treprostinil (Inh) page

“Inhaled treprostinil (Tyvaso) relaxes blood vessels in the lungs to treat pulmonary hypertension, and it also blunts platelet clotting, which is why this list of 275 ingredients warrants real vigilance rather than a shrug. Two themes cover almost everything.”

About Lotus

What is Lotus?

Lotus
  • Digestive upset and diarrhea
  • Anxiety and relaxation
  • Sleep support
  • Blood sugar and cholesterol support
  • Skin and general wellness

Lotus is an edible aquatic plant used in food and traditional medicine across Asia, with parts like the seeds, leaves, and flowers taken for digestion, calm, and overall wellness. Most health claims come from laboratory and animal research rather than strong human studies, so its benefits as a supplement are not well proven. Eating lotus as food is generally safe, but talk to your pharmacist or doctor before using concentrated supplements, especially if you are pregnant, breastfeeding, or taking other medicines.

About Treprostinil Oral Inhalation

What Is Treprostinil Oral Inhalation Used For?

Brand name: Tyvaso

Treprostinil oral inhalation is used to treat two serious lung conditions that raise pressure in the blood vessels of the lungs. It helps improve how much physical activity you can do.

Tyvaso inhalation solution and Tyvaso DPI are both indicated to treat pulmonary arterial hypertension (PAH; WHO Group 1) and pulmonary hypertension associated with interstitial lung disease (PH-ILD; WHO Group 3). Clinical studies establishing effectiveness in PAH primarily included patients with moderate symptoms (NYHA Class III) whose PAH was idiopathic, heritable, or related to connective tissue disease. Studies in PH-ILD primarily included patients with idiopathic interstitial pneumonia, combined pulmonary fibrosis and emphysema, or connective tissue disease-related lung disease.
