Potassium citrate 6.488g/5ml oral solution

BackgroundRecurrent urolithiasis is a major clinical challenge, with more than 50% of patients experiencing recurrence within 5 years. While potassium citrate effectively reduces recurrence, poor adherence due to cost and gastrointestinal side effects limits its long-term use. Citrus-based interventions, such as lime juice, have shown potential in enhancing urinary citrate and alkalinity but require further validation. This study evaluated the efficacy of a lime-based phytochemical-rich regimen (LPR) in preventing stone recurrence and reducing urinary inflammation in post-operative urolithiasis patients.ObjectiveThis multicenter, double-blind, randomized controlled trial aimed to evaluate the efficacy and safety of a novel lime-based preparation called LPR in preventing kidney stone recurrence over 24 months.MethodsIn a double-blind, randomized, placebo-controlled, multicenter trial, 173 patients with calcium oxalate urolithiasis who had undergone successful stone removal were enrolled from six hospitals in Thailand. Participants were randomized to receive either LPR or placebo for 24 months. The primary outcome was the incidence of stone recurrence confirmed by computerized topography (CT). Secondary outcomes included changes in urinary protein excretion and urinary interleukin-8 (IL-8) level, a pro-inflammatory cytokine implicated in renal inflammation and stone formation. Kaplan-Meier survival analysis and multivariate Cox regression were used to assess recurrence risk.ResultsOf 173 enrolled participants, 151 completed the study. The recurrence rate at 2 years was significantly lower in the LPR group (14%) compared to placebo (45%) (p ConclusionLPR, a lime-based supplement rich in citrate and flavonoids, significantly reduced the 2-year recurrence rate of calcium oxalate stones by approximately 76%. This effect may be mediated by increased urinary citrate excretion, alkalinization, and attenuation of renal inflammation, as evidenced by reduced urinary IL-8 and proteinuria. LPR was well tolerated, with minimal adverse effects, and may serve as a safe, cost-effective adjunct for secondary prevention in patients intolerant to conventional alkali therapy.

ObjectivesTo evaluate the antibacterial efficacy of two fluoride-containing (1450 ppm F) toothpastes with or without zinc-citrate (ZCT), hydroxyapatite (HAP) and potassium-citrate (KCit); to assess and compare their clinical effects in terms of tooth sensitivity, plaque accumulation and gingivitis, as well as patients' satisfaction.Materials and methodsHealthy, adult patients were selected and randomly assigned to two groups (n = 50): Experimental: ZCT-, HAP-, KCit- and fluoride-containing toothpaste; Control: fluoride-containing toothpaste. Salivary counts of Streptococcus mutans (S. mutans), plaque and gingival index, as well as clinically diagnosed sensitivity were recorded at baseline, and after 4 weeks. A custom-made questionnaire was used to assess patients' self-reported sensitivity (baseline and after 4 weeks) and overall satisfaction with the tested toothpastes. Data were statistically analyzed (α = 0.05).ResultsAfter 4 weeks, a statistically significant salivary reduction of S. mutans was observed in both groups (p = 0.001). Furthermore, the percentage of S. mutans decrease was significantly higher in Experimental group (p = 0.014). There were no statistically significant differences between the groups in terms of plaque and gingival index (p > 0.05). After 4 weeks, the self-reported tooth sensitivity was lower in Experimental group (p ConclusionsBoth toothpastes showed good antimicrobial effect after 4 weeks; however, the toothpaste containing ZCT, HAP, KCit and fluoride was found to be more effective in reducing the salivary counts of S. mutans than the product containing fluoride alone.Clinical relevanceToothpaste containing ZCT, HAP, KCit and fluoride can be recommended for patients at risk for developing caries and may also be beneficial for individuals experiencing dental sensitivity.
