Why are there only cough syrups and not cough tablets?
There are two types of cough — local irritations and systemic irritations.
To soothen a local irritation, medications having substances like honey and other syrups are used. Such sub-stances help the preparations to remain in throat for a longer period.
For systemic irritations, medication should be available which get quickly absorbed into the blood.
Both these things are possible better with liquids. Solids like tablets 0 take time to get absorbed after swallowing. That is why cough syrups are used for the treatment of cough.
