Carbocysteine is a mucolytic agent that is used to treat respiratory conditions such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis. It is a synthetic derivative of the amino acid cysteine and works by breaking down the thick mucus that can build up in the airways, making it easier to cough up. Carbocysteine is typically administered orally, and it is available as a syrup or capsules. The exact mechanism of action of carbocysteine is not fully understood, but it is thought to work by increasing the activity of enzymes that break down mucus, as well as by reducing the viscosity of mucus. Carbocysteine is generally well-tolerated, but it can cause side effects such as nausea, vomiting, and diarrhea. It is important to note that carbocysteine is not a cure for respiratory conditions, and it should be used in conjunction with other treatments such as antibiotics and bronchodilators. Carbocysteine is being studied for its potential therapeutic effects in a variety of other conditions, including chronic sinusitis, otitis media, and gastrointestinal disorders. It is also being investigated as a potential treatment for COVID-19.'

| mucolytic | A compound that alters the structure of mucus so as to decrease its viscosity and thereby facilitate its removal by ciliary action and expectoration. Compare with antitussives, which suppress the cough reflex, and expectorants, which are considered to increase the volume of secretions in the respiratory tract, so facilitating their removal by ciliary action and coughing. |

"A validated cough questionnaire measuring 3 aspects of daytime cough (frequency, severity, bothersomeness) on a 7 point Likert scale was used each evening to rate the passed day, as regards these aspects. The scale rates each parameter from 0 (not at all) to 6 (extremely). Every day of the trial is rated. The last evening of the study (D4) the parents rated the passed day by scoring from 0-6 each of the 3 aspects of day cough. The summed score for all aspects gives the combined day cough score. This score, ranging between 0-18, was subtracted from the sum of all aspects, also ranging between 0-18, form the basal day cough score of the day before enrollment (D0). This change is recorded as change in combined day cough score and it refers to the change from D0 to D4. Negative values of the change indicate an improvement in the condition of the patient."

Cough was measured with a validated questionnaire which asks parents to rate 5 aspects of night cough: frequency, severity, bothersomeness, child sleep and parent sleep according to a 7 point Likert scale, from 0 (not at all) to 6 (extremely). Lower scores indicate a better condition. The morning after the first night of treatment (N1) the parents rated the passed night by scoring from 0-6 each of the 5 aspects of night cough.
