RESUMO
OBJECTIVE: To prepare compound lincomycin nasal drops for children and establish a quality control method for this preparation. METHODS: Compound lincomycin nasal drops for children were prepared using lincomycin hydrochloride as main component with its content determined by polarimetry.

This preparation showed a little irritation on nasal mucosa, and it was stable within 12mon under room temperature. CONCLUSIONS: This preparation is simple and feasible in preparation technology and controllable in quality.
