Abstract
The aim of this study was to develop and evaluate the transdermal patch formulations of nifedipine. The patch formulations containing nifedipine were prepared and optimized with different ratios of vinyl and cellulose-derived polymers, drug contents, and permeation enhancers. Among the various formulations, the patch formulation containing a 1:5 ratio of ethyl cellulose and polyvinyl pyrrolidone was selected for ex vivo pharmacokinetic study based on in vitro permeation studies using stratum corneum of the pig's skin. The cumulative percentage release after the transdermal administration of the optimized patch formulation was 71.43%, and the plasma concentration of nifedipine was maintained for 16 hrs. The physicochemical evaluation study including flatness, thickness, moisture content and uptake, drug content in vitro release, and ex vivo permeation indicated satisfactory results. The formulation batch with clove oil as a penetration enhancer has shown better ex vivo permeation as compared to the formulations without enhancers and another synthetic enhancer. These results suggest that the optimized patch formulation Q3 could be further developed for clinical applications, providing the therapeutic plasma level of nifedipine over an extended period. Hence analyzing the results of the evaluation tests, in vitro and ex vivo data on the preparation and optimization of nifedipine-loaded transdermal patch, it can be concluded that the formulation shows its feasibility as an effective transdermal delivery system for nifedipine.

J Pharm Sci 2022; 111:2867-2878. [PMID: 35662543 PMCID: PMC10775835 DOI: 10.1016/j.xphs.2022.05.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 05/27/2022] [Accepted: 05/27/2022] [Indexed: 10/18/2022]
Abstract
Microneedles are used to deliver drugs topically across the skin and mucous membranes. Dissolvable microneedles are made using soluble polymers, which disintegrates in the tissue and release the entire payload instantaneously including the polymer construct. Often, a slow release of drug into the tissue is desirable to overcome the severity of side effects at the site of administration as well as systemic adverse effects. In addition, controlled release of active pharmaceutical ingredient (API) only (not the excipients) is safe and effective particularly when the drug delivery is intended to sensitive organs like the eye. In this project, the feasibility of fabricating polymer coated polymeric (PCP) microneedles to achieve a gradual release of only the active ingredient from the device was investigated. The potential application of such PCP microneedles in the dermal and intravitreal drug delivery was also explored using animal tissue models. The PCP microneedles were found to be intact even after prolonged contact with the release medium. The time at which 50% (T50%) of dextran (10 K) was released in case of microneedles prepared using 20% of core polymer (PVP-K30) was about 15 min versus less than 5 min in the case of uncoated microneedles. Whereas when the core polymer concentration was increased to 50%, the T50% was increased to 90 min. The rate of release depended on the polymer molecular weight grade. The rate of drug release was not influenced by the total amount of concentration of dextran. The PCP microneedles of lidocaine hydrochloride could constantly release the drug for up to 9 h in the skin tissue. Likewise, the PCP microneedles infused voriconazole, intravitreally for 6 h.

Abstract
AIM In the current study, efforts are being made to formulate transdermal salbutamol-cubosomal gel to manage pediatric asthma. METHODS Salbutamol-loaded cubosomal gels were prepared by melt emulsification and sonication. The cubosomal gels were characterized by morphology, particle size, zeta potential, entrapment efficacy, assay, viscosity, and texture profiles. Ex vivo permeation and pharmacokinetic studies were performed using rats. RESULTS The mean cubosomal particle size (208-361 ± 12.5-32.5 nm), PDI (0.06-0.11 ± 0.01-0.02), viscosity (8527-9019 cp), and entrapment efficacy (76.3-91.0% w/w) increase with the level of monoolein. The ex vivo permeation study showed a biphasic release pattern, with salbutamol cleared from control gel within 8 h, while cubosomal gels showed sustained release up to 72 h. The pharmacokinetic profiles in the rat model showed 8.62-fold higher bioavailability with cubosomal gel. CONCLUSION The study demonstrated the potential of cubosomal nanoparticle-laden gel to sustain the release of salbutamol to treat pediatric asthma.

Abstract
Background: Transdermal drug delivery system (TDDS) was designed to sustain the release and improve the bioavailability of drug and patient compliance. Among the various types of transdermal patches, matrix dispersion type systems disperse the drug in the solvent along with the polymers and solvent is allowed to evaporate forming a homogeneous drug-polymer matrix. The objective of the present study was to design and formulate TDDS of topiramate (TPM) and to evaluate their extended release in vitro and ex vivo. Materials and Methods: In the present study, an attempt has been made to develop a matrix-type transdermal therapeutic system comprising TPM with different ratios of hydrophilic and hydrophobic polymeric combinations using solvent casting technique. Results: The physicochemical compatibility of the drug and the polymers was studied by Fourier transform infrared spectroscopy. The results obtained showed no physical-chemical incompatibility between the drug and the polymers. The patches were further subjected to various physical evaluations along with the ex vivo permeation studies using pig ear skin. Conclusions: On the basis of results obtained from the physical evaluation and ex vivo studies the patches containing the polymers, that is, Eudragit L 100 and polyvinylpyrrolidone, with oleic acid as the penetration enhancer were considered as the best formulations for the transdermal delivery of TPM.

Abstract
The aim of present study was to prepare and evaluate buccal bioadhesive films of salbutamol sulphate (SS) for the treatment of asthma. The films were designed to release the drug for a prolonged period of time so as to reduce the frequency of administration of the available conventional dosage forms of SS. The different proportions of sodium carboxymethylcellulose (SCMC) and Carbopol 940P (CP 940P) were used for the preparation of films. Carbopol was used to incorporate the desired bioadhesiveness in the films. The films were prepared by solvent casting method and evaluated for bioadhesion, in vitro drug release and anti asthmatic effect (bronchoprotection) in histamine induced bronchospasm of guinea pigs. In vitro drug release from the film was determined using a modified Franz diffusion cell while bioadhesiveness was evaluated with a modified two-arm balance using guinea pig buccal mucosa as a model tissue. Films containing SCMC : CP 940P ratio of 76 : 24 was found to be the best with moderate swelling along with favorable bioadhesion force and in vitro drug release. The drug release mechanism was found to follow non-Fickian diffusion as release mechanism. The prolonged in vivo effect (bronchoprotection) obtained from the buccal bioadhesive film of SS administered via buccal route may improve the treatment of asthmatic disorders by reducing the frequency of administration which is associated with the tolerance effect of SS. Additionally for the clinical benefit, it is also expected to reduce the major adverse effects of SS such as tachycardia and arrhythmias via buccal absorption.

Abstract
BACKGROUND Hydrophilic matrix formulations are important and simple technologies that are used to manufacture sustained release dosage forms. METHOD Hydroxypropyl methylcellulose-based matrix tablets, with and without additives, were manufactured to investigate the rate of hydration, rate of erosion, and rate and mechanism of drug release. Scanning electron microscopy was used to assess changes in the microstructure of the tablets during drug release testing and whether these changes could be related to the rate of drug release from the formulations. RESULTS The results revealed that the rate of hydration and erosion was dependent on the polymer combination(s) used, which in turn affected the rate and mechanism of drug release from these formulations. It was also apparent that changes in the microstructure of matrix tablets could be related to the different rates of drug release that were observed from the test formulations. CONCLUSION The use of scanning electron microscopy provides useful information to further understand drug release mechanisms from matrix tablets.

Abstract
An artificial neural network was used to optimize the release of salbutamol sulfate from hydrophilic matrix formulations. Model formulations to be used for training, testing and validating the neural network were manufactured with the aid of a central composite design with varying the levels of Methocel® K100M, xanthan gum, Carbopol® 974P and Surelease® as the input factors. In vitro dissolution time profiles at six different sampling times were used as target data in training the neural network for formulation optimization. A multi layer perceptron with one hidden layer was constructed using Matlab®, and the number of nodes in the hidden layer was optimized by trial and error to develop a model with the best predictive ability. The results revealed that a neural network with nine nodes was optimal for developing and optimizing formulations. Simulations undertaken with the training data revealed that the constructed model was useable. The optimized neural network was used for optimization of formulation with desirable release characteristics and the results indicated that there was agreement between the predicted formulation and the manufactured formulation. This work illustrates the possible utility of artificial neural networks for the optimization of pharmaceutical formulations with desirable performance characteristics.

Abstract
Abstract
To improve the skin permeation of theophylline and cianidanol ((+)-catechin), the essential oil of Magnolia fargesii was evaluated using in-vitro and in-vivo permeation techniques. Oxygenated monoterpenes and sesquiterpenes are the major components of M. fargesii essential oil. The in-vitro permeation of theophylline and cianidanol was significantly enhanced after treatment with M. fargesii essential oil. The essential oil increased the in-vivo skin deposition of cianidanol but not theophylline. On the other hand, in-vivo microdialysis showed a higher subcutaneous theophylline amount after essential oil treatment. In-vitro cell viability and prostaglandin E2 release by skin keratinocytes indicated that there was low or negligible cytotoxicity by M. fargesii essential oil. The in-vivo skin tolerance study determined by transepidermal water loss and colorimetry confirmed that no irritation of the skin was detected when using M. fargesii essential oil.

Abstract
Using in vitro and in vivo techniques, terpenes were evaluated as enhancers to improve the skin permeation of therapeutically active agents derived from tea, including tea catechins and theophylline. The in vitro permeation was determined by Franz cells. The skin deposition and subcutaneous amounts of drugs sampled by microdialysis were evaluated in vivo. Terpenes varied in their activities of enhancing drug permeation. The oxygen-containing terpenes were effective enhancers of drug permeation, whereas the hydrocarbon terpenes were much less efficient. Oxygen-containing terpenes with a bicyclic structure had reduced enhancing activity. Terpenes enhanced tea catechin permeation to a much greater degree than they did theophylline. The isomers of (+)-catechin and (-)-epicatechin showed different permeation behaviors when incorporated with terpenes. In the in vivo status, terpenes promoted the skin uptake but not the subsequent subcutaneous concentration of (-)-epigallocatechin gallate (EGCG). Both increased skin/vehicle partitioning and lipid bilayer disruption of the stratum corneum (SC) contributed the enhancing mechanisms of terpenes for topically applied tea catechins and theophylline based on the experimental results from the partition coefficient and transepidermal water loss (TEWL). alpha-Terpineol was found to be the best enhancer for catechins and theophylline. The high enhancement by alpha-terpineol was due to macroscopic perturbation of the SC and the biological reaction in viable skin as evaluated by TEWL and colorimetry.

Abstract
Transdermal drug delivery formulation containing 5 mg/patch of salbutamol sulfate (SS), providing an input rate of 100 microg/h of SS was formulated and subjected for pharmacokinetic and pharmacodynamic evaluation in moderately asthmatic patients (n=6). A linear correlation was observed between cumulative amount of drug diffused in vitro and cumulative AUC0-t of serum concentration-time curve (R2=0.99). A steady-state serum concentration of 2.87+/-0.1 ng/ml (per milligram dose) was attained after an initial lag period of 4.67+/-1.03 h. The elimination half-life, clearance rate and elimination rate constant was 3.35+/-1.07 h, 256.12+/-3.55 ml/min and 0.24+/-0.09 h(-1), respectively. The mean forced expiratory volume in one minute (FEV1) of the patients was 2.2+/-0.14l during steady state. The pharmacokinetic results correlated well with the FEV1 response of patients.

Abstract
This paper reports on measurements of the release characteristics of the model drug salbutamol base from a liquid crystalline vehicle across a non-rate limiting synthetic membrane. The measured passive release rates were compared with analogous behaviour: (i) when a penetration enhancer such as oleic acid was incorporated into the vehicle; (ii) when the release was iontophoretically assisted; and (iii) when the penetration enhancer and iontophoretic assistance were used simultaneously. The effects of using isotonic phosphate buffer solution as the aqueous domain of the vehicle and in the receptor were also separately assessed. The passive release from the standard system was consistent with matrix diffusion control. The addition of oleic acid indicated association of the drug with the fatty acid so that its release into an aqueous medium was significantly retarded. With buffer ions present in the vehicle the release rate increased consistent with reduced association, and when phosphate buffer was used as a receptor medium the release rate exceeded that of the standard vehicle due to an ion exchange process. The delivery of salbutamol from the fatty acid containing systems was substantially enhanced by iontophoresis and the rates were shown to be approximately proportional to the assisting currents. The data clearly indicate the iontophoretic process to be significantly less efficient in the presence of buffer ions but with the iontophoretic delivery rates being enhanced by the presence of a fatty acid.
