PAR and Hi-Tech are pharmaceutical manufacturers. They both manufacture promethazine with codeine syrup so the only real significant difference is the taste and colour.
PAR promethazine with codeine is a purple syrup and Hi-Tech promethazine with codeine is a red syrup.
They both contain the same dose of active ingredients promethazine hydrochloride/codeine phosphate 6.25mg-10mg/5mL syrup.
