Substrate Insights

The tablets segment accounted for the largest revenue share of 45.0% in 2024, primarily due to their widespread use as the most common oral dosage form. Tablets offer several advantages, including ease of administration, cost-effective manufacturing, high stability, and compatibility with a wide range of active pharmaceutical ingredients (APIs). Their ability to support advanced coating technologies, including multilayer and osmotic systems, makes them highly suitable for sustained release applications. Furthermore, pharmaceutical companies prefer tablets for mass production and patient adherence, reinforcing their dominant position in the market.

The capsules segment is expected to grow at the fastest CAGR of 7.6% from 2025 to 2033, driven by their suitability for encapsulating moisture-sensitive drugs and enabling dual-release mechanisms. Capsules provide faster formulation flexibility and are often used for high-potency or combination drugs requiring modified release. Meanwhile, the pills segment represents a smaller portion of the market, primarily used in over-the-counter or traditional medicine formats. Although limited in industrial-scale pharmaceutical production, pills are gradually being incorporated into sustained release systems in niche therapeutic areas. However, the ease of coating and versatility offered by tablets continues to position them as the preferred substrate across both innovator and generic drug manufacturers.

Polymer Material Insights

The ethyl and methyl cellulose segment held the largest revenue share of 34.2% in 2024, owing to their excellent film-forming capabilities, stability, and broad compatibility with various APIs. These water-insoluble polymers are widely used for achieving pH-independent drug release, making them ideal for controlled and sustained release formulations. Their ease of processing, regulatory acceptance, and proven performance across a wide range of therapeutic applications have reinforced their dominant position. Moreover, their suitability for both hydrophilic and hydrophobic drug formulations makes them a preferred choice among pharmaceutical manufacturers.

The polyvinyl and cellulose acetate segment also commands a notable share, particularly due to their use in osmotic and extended-release systems where controlled permeability is crucial. Methacrylic acid derivatives, such as Eudragit polymers, are gaining traction for their pH-sensitive behavior, enabling site-specific drug release, especially in the gastrointestinal tract. Polyethylene glycol (PEG), commonly used as a plasticizer or pore former, enhances the flexibility and solubility of coating films, thereby improving drug release profiles. The others category includes polymers like hydroxypropyl methylcellulose (HPMC), polyvinylpyrrolidone (PVP), and biodegradable polymers, which are increasingly being explored in advanced drug delivery systems. While these alternatives offer specialized benefits, ethyl and methyl cellulose continue to lead due to their versatility, cost-efficiency, and well-established industry usage.

Application Insights

The in vitro segment held the largest revenue share of 63.5% in 2024, primarily due to its critical role in formulation development, quality control, and regulatory compliance. In vitro testing enables pharmaceutical companies to evaluate drug release profiles, coating integrity, and dissolution behavior under simulated biological conditions, helping to optimize formulations before advancing to clinical trials. The cost-effectiveness, reproducibility, and high-throughput capabilities of in vitro methods have made an essential step in drug development pipelines, particularly for sustained release technologies where controlled drug release is vital. 

The in vivo segment, while slightly smaller in revenue, is experiencing steady growth driven by increased clinical adoption of sustained release formulations. In vivo studies are crucial for assessing pharmacokinetics, bioavailability, and therapeutic efficacy in real-world physiological conditions. These studies validate in vitro findings and ensure safety and efficacy prior to regulatory approval and commercialization. As the demand for long-acting and patient-centric therapies continues to rise, especially in chronic disease management, in vivo applications are expected to gain further traction. Nonetheless, the dominance of the in vitro segment remains intact due to its foundational role in early-stage formulation and regulatory processes.
