Among numerous ones, one of the most renowned and commonly prescribed medicines is valoid. It comprises of an active ingredient named cyclizine hydrochloride, which is known as antihistamine. It is mainly utilised to prevent and treat nausea and vomiting types of disorders along with middle ear disorders, motion (travelling sickness). It also helps in reduction of the disorders arising due to radiotherapy or surgeries. The signs and symptoms of vomiting are entirely controlled from a specific part of the brain known as central part or vomiting centre. The vomiting centre is entirely responsible for initiating feelings of sickness (nausea) and vomiting reflexations. It gets activated when it receives some sort of nerve messages from the vestibular organs situated in the middle ear. The vestibular apparatus continuously provides feedback to the brain about the positions of the body. It is extremely essential to maintain a fit and healthy body. Besides, when something disturbs the vestibular apparatus, namely head movement following surgery or motion while travelling in a boat or car, nerve signals are sent from the vestibular apparatus to the vomiting centre. Thus, it might cause sensations such as nausea, dizziness or spinning sensations (vertigo) and the reflex of vomiting actions. At that time, in order to reduce the effects of vomiting, cyclizine works to block it. It works by blocking the histamine and muscarinic receptors in the vomiting centre that prevents the vomiting centre from receiving nerve messages. It also helps in preventing the disturbances arising in the middle ear activating mainly from the vomiting centre. It is mainly responsible for the creation of nausea, vertigo and vomiting among others.

The active ingredient of valoid, i.e. cyclizine might also help to prevent the vomiting centre from receiving varied types of messages from an area of the brain called the chemoreceptor trigger zone (CTZ). The CTZ gets stimulated by the varied agents circulating in the blood, such as anaesthetics and opioid painkillers such as morphine.
