复方苯甲酸软膏内含:苯甲酸120g、水杨酸60g,羊毛脂50g、凡士林适量共制成1000g。常规配制方法需将苯甲酸、水杨酸分别研细、过筛,然后与羊毛脂、凡士林混合研磨均匀。配制时苯甲酸、水杨酸研细过筛非常困难,并对呼吸道粘膜有强烈的刺激。我们将配制方法改进如下:先将水杨酸加入20ml 乙醇在研钵内研细,加入苯甲酸研匀,再加入少量熔化的基质研均,最后加入60℃以下熔融的基质至足量充分搅匀即得(见附表)。 Compound benzoic acid ointment contains: benzoic acid 120g, salicylic acid 60g, lanolin 50g, a total amount of Vaseline made 1000g. Conventional preparation methods need benzoic acid, salicylic acid were fine, sieved, and then mixed with lanolin, petroleum jelly uniform. Preparation of benzoic acid, salicylic acid fine screening is very difficult, and the respiratory mucosa has a strong stimulus. We will improve the preparation method is as follows: first salicylic acid 20ml of ethanol in the mortar finely ground, add benzoic acid, uniform, and then add a small amount of molten substrate research average, and finally add 60 ℃ below the melting of the substrate to a sufficient amount of sufficient Even that is (see schedule).
