On the product-type axis, 5 mg ml⁻¹ single-use ampoules lead because they map to the WHO Essential Medicines List strength and minimize dosing error in acute coronary settings. 2 ml:10 mg prefilled syringes follow; their share is expanding in day-surgery centres where rapid IV push is required without preparation time. 5 ml:25 mg vials, though chemically identical, appeal to outpatient infusion services that compound multiple doses, but occupy a narrower share due to microbial contamination risk once broached. Finally, 10 ml:50 mg high-volume presentations remain niche, used where 48-hour low-dose continuous infusions are protocolised. This market taxonomy reveals that convenience, rather than concentration alone, steers procurement budgets, with single-use formats commanding price premiums that offset modest volume growth.
