Segmental Insights

Drug Class Insights

Why Non-opioid Antitussives Segment Dominated the Antitussive Drugs Market?

The non-opioid antitussives segment held a dominant position in the market with a share of approximately 38% in 2025 because of safety concerns and strict regulations around opioid-based antitussives such as codeine. Non-opioid drugs like benzonatate and dextromethorphan are widely accepted because of their effectiveness, low risk, and suitability for both adult and paediatric use. Physicians strongly prefer non-opioids for long-term cough treatment due to their safety. In addition, over-the-counter availability further supports demand in the market.

The novel/emerging agent segment is expected to expand rapidly in the market in the coming years, because of unmet needs in chronic cough and respiratory disorders, where conventional medicines often fail to provide consistent or long-lasting relief. Pharmaceutical companies are investing in new mechanisms of action, including P2X3 receptor antagonists.

How the Oral Syrup/Liquid Formulations Segment Dominated the Antitussive Drugs Market?

The oral syrup/liquid formulations segment held the largest revenue share of approximately 46% in the market in 2025 because of its ease of use among children and elderly patients, and individuals who have difficulty swallowing tablets. Liquid formulation allows faster symptom relief, which makes them preferred choice for cough treatment. These products are widely available as over-the-counter medicines, which further supports high sales volumes.

The other forms segment is expected to grow with the highest CAGR in the market during the forecast period because of rising demand for targeted cough relief options that act locally in the throat and are convenient to use.
