Pharmacokinetic Drug-Drug Interaction between Cilostazol and Rosuvastatin in Healthy Participants.

Background And Objectives: Cilostazol improves ischemic symptoms and prevents recurrence following cerebral infarction, and rosuvastatin reduces cholesterol levels. However, no reports exist on the pharmacokinetic interactions between these two drugs in healthy adults. This study evaluated the pharmacokinetic (PK) interactions and safety of cilostazol and rosuvastatin when co-administered to healthy male participants.

13-Week Repeated Oral Toxicity and Toxicokinetic Studies of Rabeprazole Sodium and Sodium Bicarbonate Combination in Dogs.

The subchronic toxicity and toxicokinetics of a combination of rabeprazole sodium and sodium bicarbonate were investigated in dogs by daily oral administration for 13 consecutive weeks with a 4-week recovery period. The dose groups consisted of control (vehicles), (5 + 200), (10 + 400), and (20 + 800) mg/kg of rabeprazole sodium + sodium bicarbonate, 20 mg/kg of rabeprazole sodium only, and 800 mg/kg of sodium bicarbonate only. Esophageal ulceration accompanied by inflammation was observed in only one animal in the male (20 + 800) mg/kg rabeprazole sodium + sodium bicarbonate group.

Pharmacokinetic and Safety Comparison of Fixed-Dose Combination of Cilostazol/Rosuvastatin (200 + 20 mg) Versus Concurrent Administration of the Separate Components in Healthy Adults.

The combined cilostazol and rosuvastatin therapy is frequently used for coronary artery disease treatment. This open-label, 3 × 3 crossover clinical trial evaluated the pharmacokinetics and safety of a fixed-dose combination (FDC) of cilostazol/rosuvastatin (200 + 20 mg) versus a concurrent administration of the separate components (SCs) under both fasted and fed conditions. Among 48 enrolled healthy adults, 38 completed the study.

Pharmacokinetic Comparison Between a Fixed-Dose Combination of Atorvastatin/Omega-3-Acid Ethyl Esters and the Corresponding Loose Combination in Healthy Korean Male Subjects.

Purpose: Statins are widely used in combination with omega-3 fatty acids for the treatment of patients with dyslipidemia. The aim of this study was to compare the pharmacokinetic (PK) profiles of atorvastatin and omega-3-acid ethyl esters between fixed-dose combination (FDC) and loose combination in healthy subjects.

Methods: A randomized, open-label, single-dose, 2-sequence, 2-treatment, 4-period replicated crossover study was performed.

Evaluation of food effects on the pharmacokinetics of and with each bioactive compound berberine and epicatechin after a single oral dose of an expectorant and antitussive agent UI026 in healthy subjects.

Unlabelled: UI026 is an expectorant and antitussive agent which is a new combination of extract and extract. The bioactive compounds of and extracts were identified as epicatechin and berberine, respectively. This study evaluated the effect of food on the pharmacokinetics (PKs) and safety of UI026.

Double controlled release of highly insoluble cilostazol using surfactant-driven pH dependent and pH-independent polymeric blends and in vivo bioavailability in beagle dogs.

Commercially available cilostazol (CIL) tablet releases drug immediately and is given twice a day as an antiplatelet and vasodilatory agent. However, clinical usefulness of immediate release (IR) preparation is limited due to its extremely poor water solubility and the difficulty in sustaining the blood concentration, resulting in unwanted side effects such as headaches, pyknocardia and heavy-headed symptoms. To achieve once a day dosage form with enhanced solubility and controlled release, double controlled release CIL matrix tablets (DCRT) were designed by modulating a sol-gel process of binary polymeric blends of a pH-independent hydroxylpropylmethylcellulose (HPMC) and a pH-dependent polymer (carbomer) assisted with anionic surfactant (sodium lauryl sulfate, SLS).

Simultaneous analysis of acetylcarnitine, proline, hydroxyproline, citrulline, and arginine as potential plasma biomarkers to evaluate NSAIDs-induced gastric injury by liquid chromatography-tandem mass spectrometry.

Although major adverse effects associated with nonsteroidal anti-inflammatory drugs (NSAIDs) are gastric injury, assessment of NSAIDs-induced gastrointestinal adverse effects is mostly dependent on endoscopy due to the lack of plasma biomarkers. Several amino acids associated with collagenase activity and gastric mucosal mass have been suggested as plasma biomarker candidates for gastric injury. Therefore, this study aimed to develop a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the plasma biomarker candidates, i.

Pharmacokinetics and Anti-Gastric Ulceration Activity of Oral Administration of Aceclofenac and Esomeprazole in Rats.

This study examined the effects of esomeprazole on aceclofenac pharmacokinetics and gastrointestinal complications in rats. Aceclofenac alone, or in combination with esomeprazole, was orally administered to male Sprague-Dawley rats. Plasma concentrations of aceclofenac, its major metabolite diclofenac, and esomeprazole were simultaneously determined by a novel liquid chromatography-tandem mass spectrometry method.

Evaluation of the effects of food on levodropropizine controlled-release tablet and its pharmacokinetic profile in comparison to that of immediate-release tablet.

Background: Levodropropizine is a non-opioid antitussive agent that inhibits cough reflex by reducing the release of sensory peptide in the peripheral region. To improve patients' compliance, a controlled-release (CR) tablet is under development. The aim of this study was to compare the pharmacokinetic (PK) profiles of the CR and immediate-release (IR) tablets of levodropropizine.

Comparisons of the pharmacokinetics and tolerability of fixed-dose combinations of amlodipine besylate/losartan and amlodipine camsylate/losartan in healthy subjects: a randomized, open-label, single-dose, two-period, two-sequence crossover study.

Background: A fixed-dose combination (FDC) of amlodipine and losartan has been used to reduce blood pressure in patients whose hypertension is not sufficiently controlled with either drug alone. The aim of this study was to evaluate the pharmacokinetic (PK) characteristics and tolerability of an FDC of 6.94 mg amlodipine besylate (5 mg as amlodipine)/50 mg losartan potassium compared to an FDC of 5 mg amlodipine camsylate/50 mg losartan potassium in healthy subjects.
