Sample Use Guides

In Vivo Use Guide

1 tablet (200 mg of the active ingredient) at a time, twice a day after breakfast and before bedtime (for asthma). Intravenous infusion of 80mg, twice a day, solute in 500ml normal saline or 5% glucose solution (cerebral vasospasm).

Route of Administration: Other

In Vitro Use Guide

The inﬂuence of ozagrel on platelets aggregation was investigated. Platelet aggregation which was induced by ADP (5 uM) was inhibited by ozagrel. This inhibition was dependent on the concentration of the drug and was significant at 10(−6)–10(−3) M.
