A cough can be present when a person is ill or else when he is in good health. Basically, it acts when it’s needed and sometimes this ‘need’ may not be helpful, but will become a nuisance.

The modern pharmacology has given birth to many medications that is thought to be giving relief to a cough which does not seem to be useful or else is not effective.

The cough is a reflex mechanism which will expel any foreign bodies, excessive secretions within the respiratory system or else from the air passages, to the outside world. Thereby, it protects the lungs from becoming infected or else damaged.

What controls the cough reflex?

The reflex mechanism gets activated through signal receptors in the respiratory passages and in the lungs. On stimulation, they will transmit a signal to the brain which will then be sending back a response to the muscles in the region and to the diaphragm to contract forcefully to send a sudden stream of air into the outside environment.

Certain coughs will be known as ‘dry coughs’ as it doesn’t produce any phlegm at all and certain other coughs are known as ‘wet or phlegmy’ coughs for its production of mucus. Apart from these, there are coughs which are caused due to reflux of acids from the stomach and as side effects of various drugs.

How does cough remedies act?

A cough medicine for a ‘dry cough’ would act by suppressing the cough reflex in the brain and therefore is known as ‘centrally acting’. A medicine which acts in ‘wet coughs’ will stimulate to produce more phlegm or else will thin out the secretions so as to make the expulsion easy. Such elimination will remove the stimulus for the cough reflex.

What other effects will the cough remedy exert?

Apart from stimulating or suppressing the cough, it can also have decongestant properties which will constrict the dilated blood vessels in the nasal passages and thus will relieve the ‘blocked nose’. Certain other ingredients will help to soothe the throat and the air passages to be less irritating to existing stimuli. Apart from these, some remedies will have pain relieving and sedative qualities as well.
