Ecosprin 75 mg (aspirin 75 mg, low-dose) is given once daily (OD) - not twice daily (BD).

Low-dose aspirin (75-150 mg) is used for its antiplatelet effect (irreversible inhibition of platelet COX-1/thromboxane A2 production), and this effect is long-lasting for the life of the platelet (about 7-10 days), so a single daily dose is sufficient to maintain continuous platelet inhibition - there's no pharmacological benefit to splitting it into twice-daily dosing. This is consistent across standard cardiology and internal medicine references (e.g., low-dose aspirin daily for secondary stroke/cardiovascular prevention - Fuster and Hurst's The Heart, 15th Ed.).

In practice it's commonly prescribed as 0-1-0 (one tablet after lunch/dinner) or simply "1 tablet OD," typically after food to reduce GI irritation.

BD (twice-daily) dosing of aspirin is not standard for the antiplatelet/cardioprotective indication - that frequency is more associated with higher-dose aspirin used for anti-inflammatory or analgesic purposes (e.g., 300-600 mg doses in arthritis), not the 75 mg cardioprotective dose.

If a specific patient has been prescribed BD dosing, that would be an unusual instruction from their treating physician and worth double-checking directly with them, since standard practice is OD.
