Pemirolast Production Cost Reports

The report provides a detailed analysis essential for establishing a pemirolast production plant. It encompasses all critical aspects necessary for pemirolast production, including the cost of pemirolast production, pemirolast plant cost, pemirolast production costs, and the overall pemirolast production plant cost. Additionally, the study covers specific expenditures associated with setting up and operating a pemirolast production plant. These encompass production processes, raw material requirements, utility requirements, infrastructure needs, machinery and technology requirements, manpower requirements, packaging requirements, transportation requirements, and more.

Pemirolast is a mast cell stabiliser and antihistamine that is used mainly as eye drops to prevent itching from allergies like hay fever and allergic conjunctivitis. It works by blocking histamine release from mast cells and competing with histamine at H1 receptors on eye tissues.

This reduces inflammation, swelling, and watery eyes without causing drowsiness. Its dosing includes 1-2 drops in each affected eye four times daily, starting before allergy season for best prevention. It is often used alongside other therapies like steroids for severe cases. Its common side effects include transient burning or stinging upon application. Other rare risks involve corneal issues with overuse, so contact lens wearers should wait 10 minutes post-dose.

The market for pemirolast is fuelled by rising cases of allergic conjunctivitis and other eye allergies. The growth of pollution, urbanisation, ageing populations, and seasonal allergens supports its market demand. The increased awareness, better diagnostics, and demand for over-the-counter eye drops boost its market.

The innovations like preservative-free formulations and combo therapies expands its applications. The industrial pemirolast procurement is influenced by hospital tenders, bulk pharmacy purchases, and regional tenders in emerging markets. Other factors like supply chain reliability from Asian manufacturers, regulatory approvals (e.g., FDA GMP compliance), and competition from alternatives like cromolyn or olopatadine affect its market dynamics.

Raw Material for Pemirolast Production

According to the pemirolast production plant project report, the key raw materials used in the production of pemirolast include 2-amino-4-methylpyridine, ethyl 4-ethoxycarbonyl-3-oxobutanoate, and sodium azide.

Production Process of Pemirolast

The extensive pemirolast production cost report consists of the following major industrial production process:

1. From 2-amino-4-methylpyridine: The production process of pemirolast starts with reacting 2-amino-4-methylpyridine with ethyl 4-ethoxycarbonyl-3-oxobutanoate via condensation. This forms the pyrido[1,2-a]pyrimidin-4-one core, followed by nitrile installation. Then tetrazole ring formation takes place using sodium azide and ammonium chloride under high pressure and temperature. The final conversion via treatment with potassium hydroxide gives the potassium salt of pemirolast as the final product.

Pemirolast is a synthetic antiallergic agent with the molecular formula of C10H8N6O (free base) or C10H7KN6O (potassium salt). It has a molecular weight of 228.21 g/mol (free base) or 266.3 g/mol (potassium). It appears as a slightly yellow, odourless, water-soluble crystalline powder. It has a tricyclic pyrido[1,2-a]pyrimidin-4-one core with a 9-methyl group and 3-(1H-tetrazol-5-yl) with moderate lipophilicity (logP value of 1.5), and stability in aqueous ophthalmic solutions. It is non-hygroscopic, practically insoluble in nonpolar solvents but soluble in water and DMSO. It is formulated with pregelatinised starch, lactose, and magnesium stearate for tablets, with low plasma protein binding and rapid ocular absorption.
