Abstract
:
Two formulations of insulin suppositories were prepared to contain different amounts of sodium salicylate and sodium cholate as absorption promoters and also of insulin with the purpose of obtaining the most effective formulation in reducing plasma glucose levels after rectal administration to diabetic patients. The results show that insulin suppositories containing 100 mg sodium salicylate and 100 or 200 U of crystalline insulin showed no significant difference in AUC, Cmax and Tmax and both formulations showed significant reduction in plasma glucose level compared to initial values within 1.5-2 h. The results from experiments carried out in health volunteers showed that 100 mg sodium salicylate is the optimum amount to be included in insulin suppositories producing significantly higher Cmax and AUC compared to those produced after rectal administration of insulin suppositories containing 50 or 200 mg sodium salicylate. The results also show that using sodium cholate in 50 mg amount did not produce any significant reduction in plasma glucose levels of insulin dependent diabetic patients given suppositories containing 100 U of insulin, but this amount in suppositories containing 200 U of insulin was able to produce significant (p < 0.05) reduction in plasma glucose level within 1 h which lasted till end of experiment producing Cmax of 29.7 +/- 6.61% at Tmax of 1.5 +/- 0.61 h. On increasing the amount of sodium cholate to 100 mg in the suppositories, a marked (p < 0.01) reduction in plasma glucose level took place and the Cmax increased to 47.7 +/- 12.24% at Tmax of 1.5 +/- 0.63 h. This resulted in AUC of 86.7 +/- 22.4 mg%h which was non significantly higher from that produced after administration of suppositories containing 50 mg sodium cholate and 200 U insulin (62.5 +/- 17.6 mg%h). The results also show that insulin suppositories containing 100 mg sodium cholate and 200 U insulin resulted in a non significant differences in Cmax and AUC from those produced by S.C. injection of insulin (20 U) but significantly (p < 0.001) shorter Tmax. This formulation also shows non significant differences in Tmax and AUC and significantly (p < 0.05) higher Cmax than from those produced after rectal administration of suppositories containing 100 mg of sodium salicylate and same amount of insulin. Further more this formulation produced severe hypoglycemia in control healthy volunteers within 1 h of administration producing Cmax of 57.0 +/- 18.8% at Tmax of 0.75 +/- 0.35 h. The results of this study showed that the formulation containing 100 mg of sodium cholate and 200 U of insulin tested in fasted insulin dependent diabetic patients produced a maximum % reduction in plasma glucose levels (Cmax) of 47.7 +/- 12.24% at tmax of 1.5 +/- 0.63 h compared to Cmax of 50.56 +/- 6.8% at tmax of 2.93 +/- 0.19 h resulted after subcutaneous injection of 20 U insulin. These suppositories produced an area under the curve (AUC) of 87 +/- 22.4 mg%h compared to an AUC of 81 +/- 13.4 mg%h obtained after subcutaneous injection. This formulation of suppositories studied in 7 insulin dependent diabetic patients was found to abolish the 2-h post-prandial significant rise in plasma glucose levels after meal. These results show that these insulin suppositories containing 100 mg of sodium cholate and 200 U of insulin can serve as effective buffer against meal related hyperglycemia. The suppositories were safe, effective, accepted and well tolerated by the tested individuals
