Pemirolast Potassium(CAS: 100299-08-9)

Pemirolast Potassium is a potassium salt of pemirolast, a selective phosphodiesterase 4 inhibitor used in the treatment of atopic dermatitis. It has the molecular formula C19H23KN4O4 and is a white to slightly yellowish crystalline powder.

Pemirolast Potassium is primarily used in the treatment of atopic dermatitis. It works by inhibiting phosphodiesterase 4, which increases the concentration of cyclic AMP, leading to anti-inflammatory effects.

Pemirolast Potassium is generally considered safe when used as directed. However, it may cause skin irritation or allergic reactions. Users should discontinue use and seek medical advice if they experience any adverse effects.

Pemirolast Potassium should be stored in a tightly closed container to protect it from moisture. Store it in a cool, dry place away from direct sunlight and heat sources. The recommended storage temperature is between 15-25°C (59-77°F).
