INTRODUCTION
• Cough syrup is used for its antitussive and expectorant properties.
•They are sold as OTC drugs.
•These drugs contain some active ingredients.

•From a blind survey carried out within the University environments, the following were deducted :
Misuse of cough syrup is due to some its active ingredients
The active ingredients were : Codeine
Dextromethorphan
ACTIVE INGREDIENTS

CODEINE•Belongs to the Opium family.
•Codeine is the monomethylether of morphine.
• It has good antitussive and limited analgesic properties.
•High sedative and addictive capabilities.

DEXTROMETHORPHAN• It is a synthetic
substance.
• It is used for its antitussive and expectorant properties.
• Dissociative hallucinogen.

JUSTIFICATION OF STUDY
• The spread and increase in the abuse of cough syrup in Nigeria is becoming alarming and there is little or no documented report on the likely side effects of the misuse of cough syrup and as such there is no scientific knowledge on it’s biochemical implications.

AIMS.• To evaluate the biochemical effects of the abuse of cough syrup.• To bring to the public’s knowledge, especially the university
community the impact of the overdose of cough syrup.

SPECIFIC OBJECTIVES• To administer, orally different doses of the
cough syrup to rats within a specified period.
• To view and observe changes in behavioural patterns of the rats.
• To carry out toxicity test in the blood, liver, kidney and brain

MATERIALS• Study location: The location of our study would be
at Bells University of technology.
• Source of Material: The material under study is to be obtained from a local pharmacy after extensive evaluation of information provided by respondents from our survey.

EXPERIMENTAL METHODS• Acclimatisation of rats.
• Groupings of rats
• Administration of cough syrup.
• Toxicity tests.
