Indications
Pemast (Pemirolast Potassium) ophthalmic solution is used to help prevent the itchy eyes that come with allergic conjunctivitis.
⚠️ Always consult a registered physician before taking any medicine.
Pharmacology
Pemirolast works by attaching to histamine H1 receptors, blocking the action of the body's own histamine and easing the uncomfortable symptoms it causes. The medicine also curbs the entry of calcium ions into mast cells that would otherwise be triggered by an allergen, by closing off calcium channels. It further stops eosinophils from migrating into eye tissue and keeps these cells from releasing inflammatory substances there.
Pregnancy & Breastfeeding
Pregnancy: No adequate, well-controlled studies have looked at the use of pemirolast ophthalmic solution in pregnant women. It should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Lactation: Whether Pemirolast Potassium passes into human breast milk is not known. Since many drugs do pass into breast milk, this eye drop should be used with caution in a nursing mother.
⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
