Types: Within the market, codeine is offered in distinct dosage forms—immediate‑release tablets, sustained‑release tablets, and liquid syrups. Immediate‑release tablets, ranging from 15 mg to 30 mg, dominate the pain‑management segment due to rapid onset, supporting the acute‑pain share. Sustained‑release tablets, engineered for 12‑hour analgesia, are pivotal for chronic‑pain patients, aligning with the 30 % revenue share. Liquid syrups, typically 0.5 % w/v, are the primary vehicle for cough suppression, reinforcing the 25 % market portion. Each type’s formulation characteristics—bioavailability, dosing frequency, and administration route—directly influence its contribution to the overall market valuation.
