noun
granules (medicine)
Pharmaceutical term for a granular dosage form, often used in medical and pharmacy contexts.
この顆粒剤は水に溶かして服用してください。
Please dissolve these granules in water before taking them.
散剤 is a powder, whereas 顆粒剤 is a coarser granular preparation.
Compound of 顆粒 (karyū, 'granule') and 剤 (zai, 'medicine, drug'). The exact historical derivation is uncertain, but the term is a modern pharmaceutical coinage.
