Tiotropium (Spiriva) Manufacturing Plant Project Report 2025

The demand for tiotropium (Spiriva) is increasing due to increasing prevalence of chronic obstructive pulmonary disease (COPD). As per industry reports, the number of COPD cases will reach approximately 600 million by 2050, reflecting a 23% increase from 2020 levels. In 2024, the estimated prevalence of COPD among individuals aged 40 years and older is around 12.64%, highlighting a significant public health concern. This increase is notably pronounced among women, with projections suggesting a 47.1% rise in female COPD cases by 2050. Also, in low- and middle-income countries (LMICs), the burden of COPD is expected to grow at a much faster rate than in high-income countries (HICs), which is further driving demand for effective treatments like tiotropium.

Other elements to consider while establishing a tiotropium (Spiriva) plant include raw material sourcing, workforce planning, and packaging. The production of tiotropium (Spiriva) relies on several key raw materials, such as tiotropium bromide monohydrate, lactose monohydrate, magnesium stearate, and silica gel. Tiotropium bromide monohydrate is the primary active pharmaceutical ingredient (API) and is synthesised as a quaternary ammonium salt and exists as a white to yellowish-white crystalline powder. Its unique chemical structure allows it to function effectively as a long-acting anticholinergic agent, specifically targeting muscarinic receptors in the airways to induce bronchodilation. 

Another essential raw material is lactose monohydrate, which acts as a carrier for the tiotropium powder, aiding in proper delivery during inhalation and improving aerosolisation properties. Each Spiriva capsule contains approximately 5.5 mg of lactose monohydrate. Other excipients such as magnesium stearate and silica gel play crucial roles in the manufacturing process; magnesium stearate acts as a lubricant to prevent clumping of powders, while silica gel serves as an anti-caking agent to maintain powder flowability and prevent moisture absorption. These raw materials are vital for producing Spiriva in accordance with pharmaceutical standards.

Moreover, to help stakeholders determine the economics of a tiotropium (Spiriva) plant, project funding, capital investments, and operating expenses are analyzed.

About Tiotropium (Spiriva)

Tiotropium bromide is a long-acting bronchodilator primarily used for the management of chronic obstructive pulmonary disease (COPD) and asthma. Marketed under the trade name Spiriva, it functions as a muscarinic antagonist, providing sustained bronchodilation through once-daily inhalation. With a bioavailability of 19.5% and a half-life of 5–6 days, tiotropium is metabolised in the liver and is predominantly excreted unchanged. 

It is classified as a prescription-only medication in several regions, including Australia, the UK, and the US, and has a favourable safety profile, with dry mouth being the most common side effect. Tiotropium was developed in the late 1990s and received FDA approval in 2004. It was the first long-acting muscarinic antagonist (LAMA) available for COPD treatment. Its introduction marked a significant advancement in bronchodilator therapy, offering improved lung function and reduced exacerbations compared to previous treatments.

Properties of Tiotropium (Spiriva)

Tiotropium bromide, the active ingredient in Spiriva, is a non-chiral quaternary ammonium compound with a molecular formula of C₁₉H₂₂BrN₃O₄S₂·H₂O and a molecular mass of 490.4 g/mol. It appears as a white or yellowish-white powder that is sparingly soluble in water but soluble in methanol. The drug exhibits a long elimination half-life of 5–6 days and is primarily metabolised in the liver via CYP2D6 and CYP3A4 pathways. Tiotropium is delivered through inhalation, ensuring targeted action in the lungs for effective bronchodilation.

Manufacturing Process of Tiotropium (Spiriva)

The manufacturing process of tiotropium bromide (Spiriva) begins with the reaction of scopine methobromide with an anhydride compound in acetonitrile, which is heated under reflux for approximately four hours. Following this reaction, the mixture undergoes crystallisation from a methanol/acetone mixture, where it is heated to 50-60°C and then cooled to -6 to -14°C to recover crystalline tiotropium bromide. The crystalline product is then micronised to achieve the desired particle size distribution. Next, the micronised tiotropium bromide is blended with lactose monohydrate, and the resulting powder blend is filled into capsules. Finally, these capsules are packaged with the HandiHaler inhalation device, resulting in the final product, Spiriva HandiHaler, which is used for the delivery of tiotropium bromide as an inhalation powder.
