Ketotifen Liquid 1mg/mL (30mL)

Description

Our Ketotifen liquid comes as 30mL of ready-made solution at 1mg/mL, so each bottle holds 30mg of Ketotifen Fumarate, an H1 antihistamine and mast cell stabilizer. This batch tested at over 99.9% purity. It’s sold for laboratory research only.

About Ketotifen Fumarate

Ketotifen is a second-generation H1 antihistamine that also stabilizes mast cells, first developed by Sandoz in the 1970s. This liquid uses the fumarate salt.

It’s sold as eye drops in the US for allergic conjunctivitis, and as an oral drug in many other countries for asthma and allergy.

How Ketotifen Fumarate works

Ketotifen blocks H1 histamine receptors, which stops histamine’s effects on blood vessels, nerves and smooth muscle once it’s been released.

Its second action is on mast cells themselves. It stabilizes them so they release less histamine, leukotrienes and other inflammatory signals in the first place, which is why it’s used for prevention. It does little for symptoms that have already started.

Ketotifen Fumarate research

Clinical studies cover allergic asthma, allergic eye disease and chronic hives. Research also looks at mast cell disorders and conditions where mast cells drive inflammation.

Animal studies have reported that ketotifen reduces the loss of beta-2 receptors seen with continuous beta-2 agonist exposure.

The primary literature is on PubMed. Here’s a search for Ketotifen Fumarate studies to start from.

Ketotifen Fumarate compared with similar compounds

Here’s how Ketotifen liquid fits among related compounds. Ketotifen Fumarate is an H1 antihistamine that also stabilizes mast cells. By comparison:

• Clenbuterol is a long-acting beta-2 agonist studied for airway and muscle effects
• Tadalafil blocks PDE5 to boost the nitric oxide and cGMP signal
• Finasteride blocks 5-alpha reductase type 2 and cuts DHT
• Pramipexole is a dopamine agonist with a preference for D3 receptors

These liquids don’t share a research area. Each is a well-characterized approved drug from its own class, sold here as a reference compound for lab work. See them all on our research liquids page.

How to measure Ketotifen liquid

The concentration is 1mg/mL, so the math is simple: every 1mL holds 1mg, and every 0.1mL holds 0.1mg. The whole 30mL bottle holds 30mg.

Most labs measure with a 1mL measuring dropper marked in 0.1mL steps. The dropper built into the cap is handy for transfers but not precise enough for measuring.

Storing Ketotifen liquid

Keep Ketotifen liquid at room temperature with the cap tight, out of direct sunlight. It doesn’t need a fridge. Wipe the dropper tip before you put the cap back so nothing dries in the threads.

Lab-tested Ketotifen liquid

The current batch of Ketotifen liquid tested at over 99.9% purity by mass spectrometry and UV (HPLC) analysis. That figure comes from the batch report, not a marketing estimate, and it’s the reason we list the exact number instead of rounding up.

Note the batch number on the label when the bottle arrives. That’s what the certificate of analysis is filed under, and we’ll send you a copy on request.

If a result looks off, check the batch number first, then your handling notes. Most problems with Ketotifen Fumarate come from storage or mixing, not the material.
