Fabrication of acetazolamide loaded leciplex for intraocular delivery: Optimization by 3 2 full factorial design, in vitro, ex vivo and in vivo pharmacodynamics. Int J Pharm 2024; 661:124391. [PMID: 38936444 DOI: 10.1016/j.ijpharm.2024.124391] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2024] [Revised: 06/24/2024] [Accepted: 06/24/2024] [Indexed: 06/29/2024]
Abstract
The complex structure of the eye poses challenges in delivering drugs effectively, which can be circumvented by employing nanotechnologies. The present study aimed to prepareacetazolamide-loadedleciplex (ACZ - LP) using a simple one-step fabrication approach followed byoptimization employing a 32 Full Factorial Design. The ACZ - LP demonstrated high entrapment efficiency (93.25 ± 2.32 %), average diameter was recorded around 171.03 ± 3.32 with monodisperse size distribution and zeta potential of 41.33 ± 2.10 mV. Invitro release and ex vivo permeation studies of prepared formulation demonstrated an initial burst release in 1 h followed by sustained release pattern as compared to plain acetazolamide solution. Moreover, an ex vivo corneal drug retention (27.05 ± 1.20 %) and in vitro mucoadhesive studies with different concentration of mucin indicated strong electrostatic bonding confirming the mucoadhesive characteristics of the formulation. Additionally, the histopathological studies ensured that the formulation was non-irritant and nontoxic while and HET-CAM ensured substantial tolerability of the formulation. The in vivo pharmacodynamic investigation carried out on a rabbit model demonstrated that treatment with ACZ - LP resulted in a significant and prolonged reduction in intraocular pressure as compared to plain acetazolamide solution, acetazolamide oral tablet, and Brinzox®. In summary, the ACZ - LP is anefficient and versatile drug delivery approach which demonstrates significant potential in controlling glaucoma.

J Pharm Sci 2024:S0022-3549(24)00126-6. [PMID: 38582282 DOI: 10.1016/j.xphs.2024.03.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 03/29/2024] [Accepted: 03/29/2024] [Indexed: 04/08/2024]
Abstract
The purpose of this research was to formulate, optimize, and characterize ambrisentan chitosan-coated LeciPlex (AMS-CTS-LPX) to increase the therapeutic effectiveness and bioavailability of ambrisentan. A central composite design (CCD) was implemented to assess the impact of various factors on the production of AMS-CTS-LPX and to identify the optimum formulation via the use of Design Expert® software. The assembly of AMS-CTS-LPX was conducted using a single-step process. Subsequently, the optimal formulation was chosen and subjected to further assessments. Further, a comparative pharmacokinetic study was carried out using a rat model. The optimized formulation exhibited an entrapment efficiency of 82.39%, with a diameter of 137.53 nm and a surface charge of +43.65 mV. Additionally, it had a sustained cumulative release of 90.41% after 8 h and showed good stability. The safety of AMS-CTS-LPX administered intratracheally was confirmed by in vivo histopathological studies. The pharmacokinetic investigations revealed a 5.6-fold increase in the bioavailability of AMS from the optimal AMS-CTS-LPX formulation compared to the oral AMS solution. Collectively, the results of the current study suggest that CTS-LPX may be beneficial as a pulmonary nanosystem for the administration of AMS.

Abstract
The intricate structure of the eye poses difficulties in drug targeting, which can be surmounted with the help of nanoformulation strategies. With this view, brinzolamide nanosponges (BNS) were prepared using the emulsion solvent evaporation technique and optimized via Box-Behnken statistical design. The optimized BNS were further incorporated into a poloxamer 407 in situ gel (BNS-ISG) and evaluated. The optimized BNS showed spherical morphology, entrapment efficiency of 83.12 ± 1.2 % with particle size of 114 ± 2.32 nm and PDI of 0.11 ± 0.01. The optimized BNS-ISG exhibited a pseudoplastic behavior and depicted a gelling temperature and gelation time of 35 ± 0.5 °C and 10 ± 2 s respectively. In-vitro release and ex- vivo permeation studies of BNS-ISG demonstrated a sustained release pattern as compared to Brinzox®. Additionally, the HET-CAM and in vitro cytotoxicity studies (using SIRC cell line) ensured that the formulation was non-irritant and nontoxic for ophthalmic delivery. The in vivo pharmacodynamic study using rabbit model depicted that BNS-ISG treatment significantly lowers the intra ocular pressure for prolonged period of time when compared with Brinzox®. In conclusion, the BNS-ISG is an efficient and scalable drug delivery system with significant potential as the targeted therapy of posterior segment eye diseases.

Abstract
To design and evaluate hyaluronan-based cubosomes loaded with bromfenac sodium (BS) for ocular application to enhance the corneal permeation and retention in pterygium and cataract treatment. BS-loaded cubosomes were prepared by the emulsification method, employing 23 full factorial design using Design-Expert® software. Glycerol monoolein (GMO) and poloxamer 407 (P407) as lipid phase and polyvinyl alcohol (PVA) as stabilizer were the used ingredients. The optimized formulation (OBC; containing GMO (7% w/w), P407 (0.7% w/w) and PVA (2.5% w/w)) was further evaluated. OBC had an entrapment efficiency of 61.66 ± 1.01%, a zeta potential of -30.80 ± 0.61 mV, a mean particle size of 149.30 ± 15.24 nm and a polydispersity index of 0.21 ± 0.02. Transmission electron microscopy confirmed its cubic shape and excellent dispersibility. OBC exhibited high stability and no ocular irritation that was ensured by histopathology. Ex vivo permeation study showed a significant increase in drug deposition and permeability parameters through goat cornea, besides, confocal laser microscopy established the superior permeation capability of OBC, as compared to drug solution. In vivo pharmacokinetics in aqueous humor indicated higher AUC0-tlast (18.88 µg.h/mL) and mean residence time (3.16 h) of OBC when compared to the marketed eye drops (7.93 µg.h/mL and 1.97 h, respectively). Accordingly, hyaluronan-enriched cubosomes can be regarded as a promising carrier for safe and effective topical ocular delivery.

Abstract
AIM The aim of this manuscript was to fabricate agomelatine (AGM) loaded elastosomes to improve its corneal permeation and ocular bioavailability. AGM is a biopharmaceutical classification system (BCS) class II with low water solubility and high membrane permeability. It has a potent agonistic action on melatonin receptors, so it is used for glaucoma treatment. METHODS Elastosomes were made using modified ethanol injection technique according to a 22 × 41 full factorial design. The chosen factors were: edge activators (EAs) type, surfactant percent (SAA %w/w), and cholesterol:surfactant ratio (CH:SAA ratio). The studied responses were encapsulation efficiency percent (EE%), mean diameter, polydispersity index (PDI), zeta potential (ZP), percentage of drug released after two hours (Q2h%), and 24 hours (Q24h%). RESULTS The optimum formula with the desirability of 0.752 was composed of Brij98 as EA type, 15%w/w SAA%, and 1:1 CH:SAA ratio. It revealed EE% of 73.22%w/v and mean diameter, PDI, ZP, Q2h%, and Q24h% values of 484.25 nm, 0.31, -30.75 mV, 32.7%w/v, and 75.6%w/v, respectively. It demonstrated acceptable stability for three months and superior elasticity than its conventional liposome. The histopathological study ensured the tolerability of its ophthalmic application. Also, it was proven to be safe from the results of the pH and refractive index tests. The in vivo pharmacodynamic parameters of the optimum formula revealed dominance in a maximum % decrease in intraocular pressure (IOP), the area under the IOP response curve, and mean residence time with the value of 82.73%w/v, 820.69%h, and 13.98 h compared to that of the AGM solution (35.92%w/v, 181.30%h, and 7.52 h). CONCLUSIONS Elastosomes can be a promising option to improve AGM ocular bioavailability.

Abstract
Olmesartan medoxomil (OLM) is a first-line antihypertensive drug with low oral bioavailability (28.6%). This study aimed to develop oleogel formulations to decrease OLM side effects and boost its therapeutic efficacy and bioavailability. OLM oleogel formulations were composed of Tween 20, Aerosil 200, and lavender oil. A central composite response surface design chose the optimized formulation, containing Oil/Surfactant (SAA) ratio of 1:1 and Aerosil % of 10.55%, after showing the lowest firmness and compressibility, and the highest viscosity, adhesiveness, and bioadhesive properties (Fmax and Wad). The optimized oleogel increased OLM release by 4.21 and 4.97 folds than the drug suspension and gel, respectively. The optimized oleogel formulation increased OLM permeation by 5.62 and 7.23 folds than the drug suspension and gel, respectively. The pharmacodynamic study revealed the superiority of the optimized formulation in maintaining normal blood pressure and heart rate for 24 h. The biochemical analysis revealed that the optimized oleogel achieved the best serum electrolyte balance profile, preventing OLM-induced tachycardia. The pharmacokinetic study showed that the optimized oleogel increased OLM's bioavailability by more than 4.5- and 2.5-folds compared to the standard gel and the oral market tablet, respectively. These results confirmed the success of oleogel formulations in the transdermal delivery of OLM.
