There are several categories of drugs for treating cough and cold, first of all, cough drugs, such as compound methenamine capsule, compound forcodine oral solution, compound licorice tablets, coughing bacillus, etc.. Some patients with heavy cold symptoms also need oral cold medications, such as phenomethamine tablets, Lianhua Qingfei capsule, Banlangen granules, Shuanghuanglian granules, etc. Some patients with post-cold cough are often accompanied by increased airway sensitivity, so they also need to be treated with ketotifen or montelukast sodium in order to reduce their airway sensitivity and assist in relieving cough. Some patients with cough stimulated by throat itching can also take oral laxatives, such as Baicalin oral solution and Pudilan oral solution. However, it should be noted that if a viral cold is secondary to a bacterial cold causing cough, the patient also needs oral anti-inflammatory treatment with antibiotics, usually oral amoxicillin, azithromycin, cefuroxime, cefixime, moxifloxacin and other drugs.
