==Importance of oushada sevanakala==

The oushada sevanakala is mentioned especially for pacification (shamana) therapies. [A.Hr.Sutrasthana.13]

===Based on dosha===

Empty stomach – Medicines for aggravated [[kapha]] and [[pitta]] conditions should be given at this time. [Sha.Pu.2/4]<ref name=Shargadara/> In the vitiation of vyana [[vata]] medicines should be administered at this time. [Cha.Sa.[[Chikitsa Sthana]]30/299]

[Sha.Pu.2/5]<ref name=Shargadara/>

After food – Administration of medicines at this time can treat udana [[vata]] vitiation. [Cha.Sa.[[Chikitsa Sthana]]30/299] If medicine administered after breakfast helps to treat vyana [[vata]] disorders [Sha.Pu.2/7]<ref name=Shargadara/>[A.Hr.Sutrasthana.13/39]<ref name=Hridaya/>[A.S.Sutra sthana. 23/17]<ref name=Sangraha/> and if medicines are given after evening food the disorders caused by prana [[vata]] can be treated.

[A.S.Sutrasthana. 23/16]<ref name=Sangraha/>

Along with each morsel and in between two morsel – When prana [[vata]] is vitiated, medicine is to be advocated along with each morsel or in between two morsel [Cha.Sa.[[Chikitsa Sthana]]30/300] [A.Hr.Sutrasthana.13/39]<ref name=Hridaya/>[A.S.Sutrasthana.23/22]<ref name=Sangraha/> Some scholars have the opinion that to treat udaana [[vata]], medicine should be given at this time period.

*In between two morsel – Electuaries [Su.Sa.Uttarasthana.64/82]<ref name=Susruta/>

==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.<ref>M.Mustofa, S. Suryawati et al. The relative bioavailability of diclofenac with respect to time of administration. Br. J. clin. Pharmac. (1991), 32, 246-247</ref> The absorption of paracetamol after overnight fasting is five times more when ingested after a high carbohydrate diet.<ref>McGilveray, I. J. & Mattok, G. L. (1972). Some factors affecting the absorption of paracetamol. J. Pharm. Pharmac., 24, 615-619</ref> 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.<ref>Pownall R, Pickvance NJ. The optimum interval between flurbiprofen doses--scheduling for circadian rhythms in rheumatoid arthritis. Br J Clin Pract. 1987;41(4):689-693.</ref>

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.<ref>Pinar Erkekoglu, Terken Baydar. Chronopharmacokinectics of drugs in toxicological aspects: A short review for pharmacy practitioners. J Res Pharm Pract. 2012 Jul-Sep; 1(1): 3–9. doi: 10.4103/2279-042X.99670</ref>

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.<ref>Zhang C, Yu Z, Li X, Xu Y, Liu D (2014) Chronopharmacodynamics and Chronopharmacokinetics of Pethidine in Mice. PLoS ONE 9(7): e102054. doi:10.1371/journal.pone.0102054</ref>

At the same time for certain drugs like aminoglycosides the drug administration time shows no difference in pharmacokinectics and nephrotoxicity.<ref>Erik van Maarseveen, Wai Hong Man et al. Chronopharmacokinectics of once daily dosed aminoglycosides in hospitalized infectious patients. Int J Clin Pharm (2015) 37:342–347 DOI 10.1007/s11096-015-0066-7 </ref>
