The invention provides metronidazole gel free of a preservative and relates to the field of biological medicines. The metronidazole gel consists of the following components in percentage by mass: 0.01-0.1% of metronidazole, 0.1-0.5% of carbomer, 0.1-0.5% of hydroxypropyl methylcellulose, 0.1-1% of triethanolamine, 0.01-0.2% of sodium hydrogen phosphate, 0.02-0.2% of sodium dihydrogen phosphate, 1-3% of glycerinum and the balance of water. Correspondingly, the invention further provides a preparation method of the gel. Compared with the prior art, the metronidazole ophthalmic gel of the technical scheme obtained through tests and studies has relatively small influence on variation of medicinal substances (metronidazole), and is relatively good in stability; meanwhile, as no preservative is used, the metronidazole gel is relatively good in security when being used by a patient.

The invention discloses a ready-to-use puerarin ophthalmic gel preparation belonging to the field of traditional Chinese medicines.
