Studies on cationic ocular emulsions containing bipartitioned oil droplets to codeliver cyclosporin A and etodolac. Nanomedicine (Lond) 2024; 19:1035-1050. [PMID: 38686958 PMCID: PMC11221375 DOI: 10.2217/nnm-2023-0364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 03/11/2024] [Indexed: 05/02/2024] Open
Abstract
Background: To prepare ocular emulsions containing bipartitioned oil droplets to entrap cyclosporin A (0.05% w/w) and etodolac (0.2% w/w) by using castor, olive and silicon oils. Methods: The physicochemical characterizations of prepared emulsions were performed. The drug's biodistribution profiles and pharmacokinetic parameters from emulsions were checked using the ultraperformance liquid chromatography-tandem mass spectrometry method in the ocular tissues of the healthy rabbit eye model. Results: The emulsions displayed 365.13 ± 7.21 nm size and 26.45 ± 2.09 mV zeta potential. The ferrying of two drugs after releasing from emulsions occurred across corneal/conjunctival tissues to enter the vitreous and sclera following a single drop administration into the rabbit's eyes. Conclusion: The dual drug-loaded emulsions were more likely to produce synergistic anti-inflammatory activity for managing moderate-to-severe dry eye disease.

Dual Delivery of Cyclosporin A and Etodolac Using Polymeric Nanocapsules in a Rabbit Eye Model: Ocular Biodistribution and Pharmacokinetic Study. J Ocul Pharmacol Ther 2022; 38:734-744.

Abstract
Purpose: Commercially available eye drops are loaded only with a single drug. By using the polymeric nanocapsules, dual delivery of 0.05% w/w cyclosporin A (CsA) and 0.2% w/w etodolac (Edc) was achieved. An ultraperformance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS) method was developed for determining simultaneously the biodistribution and pharmacokinetic profile of CsA and Edc in ocular tissues. Methods: After one single drop instillation of nanocapsules into healthy right eyes of rabbits, the eyeballs were enucleated at 5, 15, 30, 60, and 90 min time periods to separate the 5 different ocular tissues. A liquid/liquid extraction method was used for ocular sample extraction using darunavir as internal standard. Using 3 diverse conditions such as bench-top, autosampler, and freeze-thaw, the stability of the analytes at 3 quality control samples in ocular tissues was also checked. Results: Intra- and interday precisions for both CsA and Edc in multiple ocular tissues were <10.32%, and the accuracy was <11.98%. The % bias and % RSD values for CsA and Edc were found within the acceptable limit of ±15%. The highest Cmax values were attained in cornea for both the drugs at 60 min postinstillation time point. Despite molecular size and structural differences, both CsA and Edc after liberation from nanocapsule drops can permeate into the tissues of the anterior as well as posterior segments of the eye. Conclusion: The biodistribution and pharmacokinetic data might help and strengthen our understanding of synergetic anti-inflammatory activity of CsA and Edc from nanocapsules after its ocular topical application for managing keratoconjunctivitis sicca.

[PMID: 35243012 PMCID: PMC8861132 DOI: 10.1016/j.bbrep.2022.101231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 01/28/2022] [Accepted: 02/07/2022] [Indexed: 11/25/2022] Open
Abstract
Etodolac is an FDA-approved nonsteroidal anti-inflammatory drug (NSAID) used to treat a variety of inflammatory diseases. The drug is administered as a racemate (50/50 mixture of R- and S- enantiomers), however, studies have shown that the two enantiomers have distinct biologic and pharmacokinetic differences. Wnt signaling, which plays key roles in cell proliferation, polarity, and differentiation, has been shown to be inhibited by R-etodolac; however, comparative analyses of R- and S-etodolac in this function have not been conducted. We used in silico molecular docking and TOPflash functional biologic assays to compare R- and S-enantiomers effect on Wnt signaling inhibition. Further, we used a cultivated limbal stem epithelial cell (cLSCs) model to investigate enantiospecific changes in the colony-forming efficiency (CFE) of cLSCs. The data shows that R-etodolac is a more potent inhibitor of Wnt signaling. In addition, consistently, while both enantiomers demonstrate a dose-dependent decrease in CFE of cLSCs, R-etodolac is a more potent inhibitor.

Abstract
Tolperisone and etodolac were proven to have synergistic effect for patients of acute low back pain associated with musculoskeletal spasm. In this work, a specific, highly sensitive and reproducible analytical method was developed and validated for the simultaneous determination of tolperisone and etodolac in human plasma using liquid chromatography-tandem mass spectrometric technique. Liquid-liquid extraction was optimized for sample preparation. Zorbax C8 column (3.5 μm, 50 × 4.6 mm) was used, carrying a mobile phase mixture of 10.0 mM ammonium formate: acetonitrile (40:60, v/v) pH 3.8, running in an isocratic mode. Chlorzoxazone acted as an internal standard. Sample volume of injection was 5.0 μL, analysis was achieved within 2.5 min. Detection and quantitation were performed by electrospray ionization mass spectrometry using the multiple-reaction monitoring mode. The proposed method could determine the analytes in the range of concentration 0.5 - 200.0 ng mL-1 for tolperisone and 0.05 - 20.0 μg mL-1 for etodolac. Findings of inter- and intra-day precisions were ≤ 12.3% with accuracy of ± 5.0%. Pharmacokinetics study for the two drugs after oral administration of healthy human volunteers was achieved with the aid of application of the developed study. This article is protected by copyright.

Abstract
The objective of this study was to prepare time-controlled release etodolac pellets to facilitate drug administration according to the body's biological rhythm, optimize the drug's desired effects, and minimize adverse effects. The preparation consisted of three laminal layers from center to outside: the core, the swelling layer, and the insoluble polymer membrane. Factors influenced the core and the coating films were investigated in this study. The core pellets formulated with etodolac, lactose, and sodium carboxymethyl starch (CMS-Na) were prepared by extrusion-spheronization and then coated by a fluidized bed coater. Croscarmellose sodium (CC-Na) was selected as the swelling agent, and ethyl cellulose (EC) as the controlled release layer. The prepared pellets were characterized by scanning electron microscopy and evaluated by a dissolution test and a pharmacokinetic study. Compared with commercial available capsules, pharmacokinetics studies in beagle dogs indicated that the prepared pellets release the drug within a short period of time, immediately after a predetermined lag time. A good correlation between in vitro dissolution and in vivo absorption of the pellets was exhibited in the analysis.
