A STUDY ON DRUG-DRUG INTERACTION BETWEEN GLIPIZIDE AND CIMETIDINE IN RABBITS
Objective: To study the effect of Cimetidine (H2 receptor antagonist) in combination with Glipizide (Sulfonylurea) on the blood sugar level in rabbits.
Methods: Six albino rabbits were taken for the study. Glipizide was administrated to each rabbit as a single drug therapy on day 1 and it was co-administrated with Cimetidine to each rabbit as a combinational drug therapy on day 7. Cimetidine was administrated to each rabbit from day 2 to day 6 as single drug therapy. Blood sugar levels were estimated on day 1 and on day 7 at 0, 1, 2, 4, and 6 h.
Results: The mean blood sugar level readings at 0, 1, 2, 4 and 6 h on day 1 were 90.4, 69.4, 62.9 and 65.7 mg% and on day 7 were 89.4, 74.8, 65.5, 56.4 and 61.2 mg % respectively. When mean blood sugar level on day 1 and day 7 was considered, there was a significant reduction in blood sugar level at 1, 2, 4 and 6 h and there was no significant fall in blood sugar level at 0 hour after co-administration of Glipizide and Cimetidine.
Conclusion: Cimetidine, when co-administered with Glipizide, significantly increases the hypoglycaemic action of Glipizide
A RANDOMIZED CONTROLLED TRIAL OF CURCUMIN AND DICLOFENAC COMBINATION IN KNEE OSTEOARTHRITIS
Objective: The objective of the study was to evaluate pain relief and safety of the combination of curcumin and diclofenac versus diclofenac alone in the treatment of knee osteoarthritis (OA).
Methods: 140 patients of knee OA meeting inclusion criteria were randomized to receive either curcumin 500 mg with diclofenac 50 mg twice daily or diclofenac 50 mg tablet alone twice daily for 28 d. Patients were assessed at baseline, Day 14 and Day 28. Primary efficacy measure was severity of pain (Visual Analogue Scale) at day 14 and day 28. Safety after treatment was evaluated by recording side effects and laboratory investigations.
Results: Patients receiving curcumin plus diclofenac showed significantly superior improvement in severity of pain at each study visit (p<0.001) when compared to diclofenac. Adverse effects were significantly less in curcumin plus diclofenac group (p<0.001).
Conclusion: Combination of curcumin and diclofenac showed a significant improvement in pain on the basis of VAS when compared to diclofenac which may be due to synergistic effect between curcumin and diclofena
Drugs used in postoperative care of bypass surgery- An overview
Postoperative care of cardiac surgical patients have shown important changes parallel to the surgical improvements in recent years. The post-operative approach to these patients is best directed by dividing their problems into the systems like cardiovascular care, Bleeding-Thrombosis and Transfusion Strategies, CNS care, Respiratory & renal care, Postoperative pain and sedation management and lastly managing complications if any. The present article explains the drugs as therapeutic agents used in management of post-operative bypass surgery
Evaluation of anticonvulsant activity of angiotensin receptor antagonists in an animal model
Background: Epilepsy is common chronic disorder in clinical practice and there was some studies which shows brain renin angiotensin system may be involved in upregulation of seizures hence present study was planned to investigate whether angiotensin II AT1 receptor antagonists possess anticonvulsant activity in experimental animals.Methods: The anticonvulsant activity of angiotensin receptor antagonists, losartan (50 mg/kg), telmisartan (30 mg/kg) and candesartan (20 mg/kg), were administered intraperitoneally to the mice and evaluated by using maximum electroshock (MES) and pentylenetetrazol induced seizures (PTZ) seizure methods. The standard was taken as phenytoin for MES and diazepam for PTZ method. Motor impairment of performance was assessed by the inverted screen test and spontaneous motor activity with digital actophotometer.Results: Losartan demonstrated the anticonvulsant efficacy in MES and PTZ models. Telmisartan and candesartan have anticonvulsant activity in MES induced seizures, but did not show protection against pentylenetetrazol induced seizures. Losartan at dose 50 mg/kg prolonged the mean latency to convulsion (p<0.01) and mean number of convulsions also significantly reduced (p<0.05) convulsions in the mice. Telmisartan and candesartan at dose 30 mg/kg and 20 mg/kg respectively showed significant prolongation in mean latency to convulsion (p<0.05). None of the test drugs i.e. angiotensin receptor antagonists showed significant motor impairment.Conclusions: Angiotensin receptor antagonists: losartan, telmisartan and candesartan had showed anticonvulsant activity in PTZ and MES seizure methods. The exact mechanism of action of their anticonvulsant action not precisely known and hence there is more studies need to test it in various other animal anticonvulsant models
