lisinopril and Osteoarthritis

The present study was designed as an open label, multiple-dose, randomized, parallel trial to evaluate the pharmacodynamic drug-drug interaction of lisinopril and concomitantly administered diclofenac sodium in non-diabetic and diabetic, mild to moderate hypertensive, osteoarthritic patients.. Post-screening and on inclusion, patients were put on a 2-week washout period and then randomly assigned to either only lisinopril 10 mg or combination of lisinopril 10 mg and diclofenac sodium 100 mg treatments for 8-12 weeks in diseased states of hypertension and osteoarthritis with or without type 2 diabetes mellitus.. The blood pressure (BP) control with lisinopril was reduced by concomitantly administered diclofenac sodium in non-diabetic (SBP: p=0.00002; DBP: p=0.000008) and diabetic (SBP: p=0.002; DBP: p=0.001) patients when compared with the patients receiving lisinopril alone. Insulin sensitivity was improved (p=0.00002) and urinary albumin excretion rate was better controlled (p=0.0096) in lisinopril-treated patients when compared with the combination treatment in diabetic pool. Serum creatinine levels increased significantly in non-diabetic patients (p=0.00004) receiving combination treatment. In addition, creatinine clearance (CLCR) and blood urea nitrogen (BUN) were significantly higher in diabetic (CLCR: p<0.00001; BUN: p=0.0098) as well as in non-diabetic (CLCR: p<0.00001; BUN: p=0.03) patients treated with combination treatment. The alterations in serum electrolytes, reduction in % platelet aggregation activity and improvement in lipid profile was more profound with combination treatment in comparison to lisinopril alone.. The antihypertensive efficacy and insulin sensitivity improving property of lisinopril along with the renal function might get worse in hypertensive osteoarthritic patients receiving concomitant treatment of oral diclofenac sodium with lisinopril. In addition to this, close monitoring of serum electrolytes is also suggested to rule out any long-term detrimental effect.

Non-steroidal anti-inflammatory drugs (NSAIDs) may increase blood pressure (BP) and blunt the effects of many antihypertensives. It seems that NSAIDs and the antihypertensive drugs differ in their propensity to such an interaction.. To determine the extent of the interaction between two antihypertensives and three NSAIDs.. A prospective clinical trial in a family practice included 88 treated hypertensives aged over 55 years; 39 controls and 49, also taking NSAIDs for osteoarthritis. During this 3-month study, two antihypertensives, lisinopril/hydrochlorothiazide and amlodipine, were compared with three NSAIDs: ibuprofen, acetaminophen, and piroxicam. BP was measured with standard mercury sphygmomanometer and with an automatic device, in standing, sitting, and supine position.. The average starting blood pressure in the study group was 149.3A+/-9.8/88.6A+/-6.8 mm Hg. In the lisinopril/hydrochlorothiazide subgroup, both ibuprofen and piroxicam elevated systolic BP by 7.7-9.9% (p<0.001), which, during the acetaminophen period, decreased by 6.9-9.4% to 0.3-0.9% above baseline (p<0.001), increasing again by 7.0-7.7% (p<0.001) during the second exposition to these drugs. In the amlodipine subgroup, ibuprofen or piroxicam increased BP by 1.1-1.6% (p>0.290) only, and there were no significant shifts in the follow-up periods. Analogous deviations were observed with both measurement devices, in all the examinee's positions. In the control group, BP did not change appreciably.. Piroxicam and ibuprofen markedly blunt the effects of antihypertensive drugs while acetaminophen is almost inert. Lisinopril/hydrochlorothiazide combination is much more affected by this interaction than amlodipine (ClinicalTrials.gov #NCT00631514).

To compare the effect on antihypertensive efficacy produced by the addition of indomethacin to the angiotensin II (Ang II) antagonist, valsartan, or to the angiotensin-converting enzyme inhibitor, lisinopril, in hypertensive patients with chronic osteoarthritis.. One hundred and twenty-eight patients (52 men and 76 women) aged 25-82 years (mean age 55.7 years), with diastolic blood pressure (DBP) > 100 mmHg at the end of a 2-week placebo washout period were allocated randomly to groups to receive valsartan (80-160 mg once daily) or lisinopril (10-20 mg once daily). At the end of 10 weeks of treatment, patients with DBP < 90 mmHg, while continuing to receive valsartan or lisinopril treatment, were allocated randomly to groups to receive either indomethacin (50 mg three times a day) or the corresponding placebo for 2 weeks, with a 1-week washout period between the two treatments, according to a double-blind, crossover design. After the initial washout period, patients were examined at the end of the 4th, 8th and 10th weeks of randomized treatment with valsartan and lisinopril, at the end of the first crossover period and then at the beginning and at the end of the second crossover period. At each visit, sitting and standing blood pressure were measured by standard mercury sphygmomanometer.. The addition of indomethacin blunted the blood pressure-decreasing effect of both antihypertensive drugs. Although indomethacin produced greater increases in both systolic and DBP values in the lisinopril-treated patients (5.45/3.22 mmHg) than in the valsartan-treated ones (2.12/1.87 mmHg), no significant difference between the two drugs was found.. From a theoretical standpoint, these findings suggest that prostaglandins may play a part in the antihypertensive action of Ang II antagonists. From a practical standpoint, hypertensive patients treated with valsartan or with lisinopril should be monitored to detect changes in blood pressure control while receiving indomethacin.

To determine the impact of three non-steroidal anti-inflammatory drugs on the efficacy of two anti-hypertensive drugs.. Fifteen women with arthritis and hypertension who were receiving lisinopril and HCT, and administered sequentially in random order ibuprofen, sulindac, and diclofenac for one month each, with an intervening two-week washout period between each treatment period. During the washout period, subjects received paracetamol.. Hypertension Clinic, Medical Centre, Harare, Zimbabwe.. Fifteen female hypertensive women with documented arthritis.. Blood pressure at the end of two weeks of paracetamol was compared with blood pressure after one month of treatment with each of the NSAID.. Mean blood pressure was unchanged before and after all NSAIDs: 108 +/- 7 versus 107 +/- 9 for diclofenac, 108 +/- 9 versus 108 +/- 9 for sulindac, and 108 +/- 8 versus 107 +/- 9 for ibuprofen. The 24 hour urinary sodium excretion was not significantly different.. The three NSAIDs investigated did not neutralise the antihypertensive effect of the combination of lisinopril and HCT, and hence the blood pressure lowering action of the combination may not be prostaglandin dependent.

New imaging techniques have allowed for the rapid and accurate diagnosis of stroke. In this case, we present a 58-year-old woman with multiple large vessel strokes on magnetic resonance imaging. The initial diagnostic workup centered on a rapidly progressive central nervous system vasculitis. Subsequent workup revealed an unusual infectious etiology--cryptococcal meningitis. Although fungal infections can cause vasculitis, this is the first report of a patient with multiple anterior and posterior circulation strokes secondary to Cryptococcus. The diagnosis in cases presenting with encepalopathy and without fever is often delayed.
