An open-label, single-arm clinical study evaluated the efficacy and safety of a novel all natural/plant-based ointment formulation on diaper rash in healthy infants aged 0-36 months.Mothers/legal representatives of the subjects applied 1•5 g to 2•5 g diaper rash ointment on and around the affected areas along with each diaper change for 14 days.Overall severity of diaper rash, skin itching, skin redness, erythema, and skin dryness were evaluated at different time intervals.The overall severity score of diaper rash significantly reduced from baseline to 12 h (p<0•0001), 24 h (p<0•0001), Day 07 (p<0•0001), and Day 14 (p<0•0001).Overall severity started reducing from 6 hours with significant reduction at 12 h, thus the onset of action is less than 12 hours.Skin itching scores significantly reduced at all visits.Skin redness/erythema scores reduced significantly at 24 h (p=0•001), Day 07 (p<0•0001), and Day 14 (p<0•0001).Skin dryness scores significantly reduced at 24 h (p<0•02), Day 07 (p<0•0001), and Day 14 (p<0•0001).No cases of skin hypersensitivity reactions or any adverse events were reported during the study.Diaper rash ointment effectively reduces the overall severity of diaper rash, skin itching, redness, erythema, and dryness after application to the affected area.It is gentle and safe on baby's skin and promotes skin healing by providing effective moisturization.

Objective: A selective, sensitive and rapid liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay has been developed for the determination of celecoxib (CXB) in negative ionization mode.Methods: Celecoxib and celecoxib-D7 (CXB-D7) as internal standard (IS) were extracted from 300 µl human plasma by solid-phase extraction using strata-X SPE cartridges. Chromatographic separation was achieved on ACE C8-300 (50 × 4.0 mm, 3.0 μm) column using methanol-1.0 mmol ammonium acetate solution in 80:20 (v/v) ratio. The protonated precursor to product ion transitions studied for CXB and CXB-D7 were m/z 380.0 → 315.9 and 387.0 → 323.0, respectively.Results: The limit of detection (LOD) and lower limit of quantitation of the method were 2.50 and 10.0 ng/ml respectively with a linear dynamic range of 10.0-4000 ng/ml for CXB. The intra-batch and inter-batch precision (% CV) and mean relative recovery across quality control levels is&lt;7.2 % and 85.5 % respectively. Matrix effect in human plasma, expressed as IS-normalized matrix factor ranged from 0.99-1.03.Conclusion: The method was successfully applied in healthy subjects using a single dose of 400 mg celecoxib capsules under fasting and fed conditions. The reproducibility in the measurement of study data is demonstrated by incurred sample reanalysis.

Peroxisome proliferator-activated receptors (PPARs) have recently become a focus of interest for their important roles in glucose and lipid metabolism. In humans, PPARα activation causes a decrease in plasma triglyceride (TG) levels, enhancement of high-density lipoprotein cholesterol (HDL-C) and simultaneous enhancement of very-low-density lipoprotein (VLDL) lipolysis, whereas PPARγ agonists act as insulin sensitizers and improve insulin resistance, which is very useful in patients with type 2 diabetes mellitus (T2DM). Saroglitazar magnesium is a dual PPAR agonist with potent predominant PPARα and moderate PPARγ activity and the first glitazar to be granted marketing authorization in India. This study was conducted to evaluate the oral bioavailability and safety and tolerability of a Lipaglyn™ (saroglitazar magnesium) 4-mg tablet in healthy, adult human subjects under fed relative to fasting conditions. This was a single-dose, open-label, randomized, single-treatment, two-period, two-conditions (fed vs. fasting), two-sequence, crossover study planned in 54 healthy subjects. Food effect (high-calorie and high-fat breakfast) was examined by comparing pharmacokinetic data of saroglitazar and its metabolite saroglitazar sulfoxide in plasma samples collected pre-dose and serially up to 72h post-dose. Pharmacokinetic data were analyzed using the standard non-compartmental approach. A total of 54 subjects were enrolled in the study, out of them 50 subjects had completed the study and were analyzed. The presence of food had a minor impact on the disposition of saroglitazar. While food reduced C max (maximum concentration) of saroglitazar by 30%, the extent of absorption as measured by AUC∞ (area under the concentration time curve from time zero to infinity) was not influenced. This was further supported by the bioequivalence data between fasted and fed conditions for saroglitazar, where 90% CIs (confidence intervals) of the adjusted geometric mean of the fed relative to the fasted condition ranged from 101.37% to 108.07% for AUC∞ and from 63.45% to 74.68% for C max. Other parameters such as T max (time of maximum concentration) and T 1/2 (elimination half-life) were not influenced by the food intake. Saroglitazar was well tolerated in the study, and the reported adverse events were mild in nature. For the single-dose study, the absorption rate is affected by food as the 90% CI of C max is outside 80.00-125.00%. However, there is no impact of food on the extent of absorption of saroglitazar. The observed lower C max of saroglitazar with food has no clinical relevance since the therapeutic efficacy of saroglitazar was achieved after multiple-dose administration, suggesting the importance of total exposure.

ObjectiveThis phase I study of ZYAN1 was conducted to evaluate the safety, tolerability, and pharmacokinetics following oral administration in healthy volunteers.MethodsThe study was a randomized, double-blind, placebo-controlled phase I study carried out in two parts in addition to a third part involving an open-label study to evaluate the food/sex effect. A total of 100 subjects were enrolled into the study as follows: part I—single-dose study with ZYAN1 10, 25, 50, 100, 150, 200, and 300 mg (n = 56); part II—multiple-dose study with every other day dosing of ZYAN1 100, 150, 200, and 300 mg (n = 32); and part III—sex and food effect study with ZYAN1 150 mg (n = 12; open-label).ResultsZYAN1 was well-tolerated after single and multiple oral ascending doses. No drug-related serious adverse events were reported. Following a single ascending dose of ZYAN1, the maximum concentration (C max) ranged from 566.47 ± 163.03 to 17,858.33 ± 2899.19 ng/mL and the median time to C max (t max) was approximately 2.5 h for the studied 30-fold oral doses of ZYAN1. Regardless of single or multiple doses, mean C max and area under the concentration–time curve from time zero to time t (AUCt) values generally showed a dose-proportional increase. The mean elimination half-life (t ½) of ZYAN1 ranged from 6.9 to 13 h with negligible accumulation. Following a single dose of ZYAN1, the mean serum erythropoietin (EPO) C max values showed dose response (i.e., 6.6 and 79.9 mIU/L for 10 and 300 mg ZYAN1 doses, respectively), while the time to mean maximal serum EPO concentrations ranged from 10 to 72 h.ConclusionOral single (10–300 mg) and multiple dosing (100–300 mg) of ZYAN1 in healthy subjects was found to be safe and well-tolerated. With increasing ZYAN1 dose, there was almost a proportional increase in mean C max and AUCt. The mean serum EPO concentrations showed a trend of dose response. Based on the t ½, pharmacodynamic activity, and lack of drug accumulation, a once every 2 days dosing regimen of ZYAN1 was appropriate for phase II study.

A reliable, rapid, and selective liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay has been proposed for the determination of rizatriptan in human plasma using sumatriptan as internal standard (IS). The analyte and IS were extracted from 300 μL human plasma via liquid-liquid extraction and the chromatography was achieved on Hypurity C18 (50 mm × 4.6 mm, 5 μm) column under isocratic conditions. Detection of rizatriptan and IS was done by tandem mass spectrometry, operating in positive ionization and multiple-reaction monitoring mode. The limit of detection and lower limit of quantitation of the method were 0.04 and 0.20 ng/mL, respectively, with a linear dynamic range of 0.20–60.0 ng/mL. The intrabatch and interbatch precision (% CV) was ≤8.4% while the mean extraction recovery was &gt;78% across quality control levels. Bench top stability, freeze and thaw stability, processed sample stability, and long-term stability in plasma were evaluated at two quality control levels. It was successfully applied to a bioequivalence study of 10 mg rizatriptan orally disintegrating tablet formulation in 40 and 32 healthy Indian male subjects under fasting and fed conditions, respectively. The reproducibility in the measurement of study data was demonstrated by reanalysis of 254 incurred samples.
