Practical application to drug treatments

• circadian rhythms coordinate a number of the body’s basic processes such as heart rate, digestion and hormone levels
• this intern has an effect on pharmacokinetics, that is, the action of drugs on the body and how well they are absorbed and distributed
• Research into circadian rhythms has revealed that there are certain peak times during the day or night when drugs are likely to be at their most effective
• This has led to the development of guidelines to do with the timing of drug dosing for a whole range of medication including anti cancer, cardiovascular, respiratory, anti ulcer and anti-epileptic drugs (Baraldo 2008)
