Cromolyn Sodium

Cromolyn sodium is a medication that helps prevent asthma attacks and allergic reactions. It is a mast cell stabilizer, meaning it prevents the release of histamine and other chemicals from mast cells, which are involved in allergic reactions.

Chemical Structure and Properties

Cromolyn sodium is a synthetic compound with the chemical formula C₂₅H₂₃NaO₁₁. It is a white, crystalline powder that is soluble in water. Cromolyn sodium is a relatively stable compound and can be stored at room temperature.

Mechanism of Action

Cromolyn sodium works by preventing the release of histamine and other chemicals from mast cells. Mast cells are a type of white blood cell that plays a role in allergic reactions. When exposed to an allergen, mast cells release histamine and other chemicals that cause symptoms such as sneezing, itching, and swelling. Cromolyn sodium prevents the release of these chemicals, thereby preventing allergic reactions.

Pharmacokinetics of Cromolyn Sodium

Cromolyn sodium is a mast cell stabilizer that is used to prevent asthma attacks. It works by inhibiting the release of histamine and other inflammatory mediators from mast cells. Cromolyn sodium is available in oral, inhaled, and topical formulations.

Absorption, Distribution, Metabolism, and Excretion

Cromolyn sodium is poorly absorbed from the gastrointestinal tract. Its oral bioavailability is less than 5%. After oral administration, it is rapidly metabolized in the liver and excreted in the urine.

Cromolyn sodium is also poorly absorbed from the lungs. After inhalation, it is deposited in the airways, where it exerts its therapeutic effect. However, only a small amount of the inhaled drug is absorbed into the bloodstream.

Topical administration of cromolyn sodium is used for treating allergic conjunctivitis. When applied topically, it is absorbed into the conjunctiva and exerts its anti-inflammatory effects.

Comparison of Administration Routes

Cromolyn sodium is available in various formulations, each with its own pharmacokinetic profile. Here’s a comparison of the oral, inhaled, and topical routes:
