1. Types of cough

Cough is usually divided into two types: dry cough and wet cough. Dry cough refers to a cough caused by dryness and irritation in the throat, which is common in colds, allergic coughs and other symptoms. Wet cough refers to a cough with phlegm, which is common in viral infections, inflammatory reactions and other symptoms.

Different types of cough require different medications to treat. For dry cough, commonly used drugs include cough syrups, expectorants, etc.; for wet cough, expectorants, antibiotics, etc. can be used.

2. Cough medicines

Cough medicines include central cough medicines and peripheral cough medicines. Central cough medicines mainly act on the central nervous system and are used to treat dry cough; while peripheral cough medicines Cough medicine relieves wet cough by inhibiting the alveolar structure.

The specific type of cough medicine to be used needs to be selected based on the type of cough, dosage, route of administration, etc. It should be noted that centrally acting cough medicines can easily cause dependence, so they should be used according to the doctor's instructions to avoid abuse or overuse.

3. Expectorants

Expectors can be divided into irritating and non-irritating. Stimulant expectorants can promote the secretion of sputum from respiratory epithelial cells, making it easier to cough up sputum; non-irritant expectorants help the discharge of sputum by changing the viscosity and fluidity of sputum.

The use of expectorants should be selected according to the patient's sputum type, sputum volume and sputum quality. Commonly used expectorants in clinical practice include ambroxol tablets, bromhexine oral solution, etc.

4. Anti-allergic drugs

Anti-allergic drugs can be used to treat coughs caused by allergies. Allergy medications typically include antihistamines and anti-allergy medications. Antihistamines can be used to relieve respiratory symptoms caused by allergies, such as rhinitis, laryngitis, asthma, etc. Anti-allergic drugs can inhibit the body's response to allergens and reduce allergic symptoms.

When using anti-allergic drugs, you need to pay attention to the dosage and medication time. Excessive and long-term use will increase adverse reactions and side effects.
