  • In between two morsel – Electuaries [Su.Sa.Uttarasthana.64/82][3]

Current researches

The study of how the effects of drugs vary with biological timings is called chronopharmacology. In a study it is reported that the absorption of diclofenac was significantly low if administered in the evening when compared with the morning dosage. It also shows a delay in absorption for the evening dosage.[6] The absorption of paracetamol after overnight fasting is five times more when ingested after a high carbohydrate diet.[7] The drug flurbiprofen shows more effective in improving the symptoms like pain and spinal flexibility in rheumatoid arthritis patients if given in morning than in evening. This suggests that the time of drug administration may also be a factor which influences the therapeutic efficacy.[8]

For certain drugs the time of administration may be as important as the dose and route of administration. In order to prevent the variations in pharmacokinectics of a drug the time of administration should also be controlled. Lipophilic drugs are found to be absorbed faster in the morning when compared to the evening. In a day gastric acid secretion, gastric pH, gastric motility, gastric emptying time and gastric blood flow vary according to time. These factors might have an impact over the absorption of drug.[9]

A large number of drugs like analgesics, antibiotics, antitumor drugs, immunosuppressive agents, cardio vascular drugs, antidepressants etc show varying potency and disposition kinectics based on the time of drug administration.[10]

At the same time for certain drugs like aminoglycosides the drug administration time shows no difference in pharmacokinectics and nephrotoxicity.[11]
