Special Issue Information

Dear Colleagues,

Despite the significant advancements in pharmaceutical technology and the development of novel drug delivery systems, conventional solid dosage forms, such as tablets or capsules, remain the most widely produced and trusted by patients. Their manufacturing is influenced not only by technological processes but also by the selection of excipients within the formulation. These factors enhance product quality, boost production efficiency, and lower overall costs.

Nevertheless, with increasing market competition and the need for cost-effective manufacturing strategies, advances in efficiency, drug quality, and safety remain crucial for the sustainability of pharmaceutical companies. A comprehensive understanding of formulations and manufacturing processes is therefore essential.

This Special Issue highlights the recent advancements in the design and manufacture of oral solid dosage forms. It summarizes cutting-edge research that deepens the understanding of manufacturing processes for tablets, capsules, granules, powders, and related formulations. Of particular interest are modern and complex forms, such as multi-layer tablets or combination drugs, etc., which pose unique challenges and opportunities in pharmaceutical development.

You may choose our Joint Special Issue in Journal of Pharmaceutical and BioTech Industry.

Development and Evaluation of a Modified Fixed-Dose Combination Antihypertensive Tablet Containing S-Amlodipine Besylate: A Bioequivalence and Stability Study
by Hyeon Woo Moon, Jin-Hyuk Jeong and Chun-Woong Park

Abstract
Background/Objectives: Fixed-dose combination (FDC) antihypertensive medications containing olmesartan medoxomil, amlodipine besylate, and hydrochlorothiazide are widely used for the treatment of essential hypertension. Although effective, the use of racemic amlodipine, which contains both active S(−)-amlodipine and inactive R(+)-amlodipine, has been associated [...] Read more.
Background/Objectives: Fixed-dose combination (FDC) antihypertensive medications containing olmesartan medoxomil, amlodipine besylate, and hydrochlorothiazide are widely used for the treatment of essential hypertension. Although effective, the use of racemic amlodipine, which contains both active S(−)-amlodipine and inactive R(+)-amlodipine, has been associated with dose-dependent adverse effects, such as peripheral edema. S-amlodipine, a pharmacologically active enantiomer, provides comparable antihypertensive efficacy at half the dose with a lower incidence of side effects. Methods: In this study, a modified FDC formulation was developed by replacing racemic amlodipine with S-amlodipine to enhance tolerability while maintaining therapeutic efficacy. Results: A bilayer tablet design was employed to minimize the formation of impurities and ensure formulation stability, which was confirmed under stress and accelerated conditions. In vitro dissolution testing demonstrated pharmaceutical equivalence with the marketed reference FDC, and an in vivo pharmacokinetic study confirmed bioequivalence. Conclusions: These results suggest that the newly developed S-amlodipine besylate-containing FDC tablet is a viable alternative to existing olmesartan/amlodipine/hydrochlorothiazide combinations, offering comparable efficacy and pharmacokinetic properties with the potential for improved safety and patient adherence in the management of hypertension.

Background: Enhancing bioavailability is the target of most pharmaceutical research; this can be achieved by modifying the physico-chemical characteristics of poorly water-soluble drugs intended for oral administration using different techniques. The preparation of liquitablets by blister molding technique provides an opportunity to increase the bioavailability of the drug using an optimal combination of release-facilitating additives. Lornoxicam is an effective non-steroidal anti-inflammatory drug with low water solubility. This study aimed to formulate a novel lornoxicam-containing liquitablets. The effect of different drying techniques on the physico-chemical properties and in vitro dissolution of lornoxicam was investigated. The physical parameters of the tablets were also studied. Methods: The additives applied in the formulation included Tween® 80, Polyvinylpyrrolidone (PVP K90), Avicel® PH-102, and sodium bicarbonate. Vacuum-drying and freeze-drying were employed to produce liquitablets. The influence of various drying methods on crystallinity and intra- and interparticle phenomena was investigated. In Vitro dissolution tests were performed at pH 1.2, and a comparison was made between our products and commercial tablets using the pairwise similarity factor model (f2). Results: The liquitablets demonstrated high hydrophilicity and a lower crystallinity of the drug. Freeze-dried liquitablet showed improved dissolution compared to that of the pure drug or the vacuum-dried product. A similarity was observed between our freeze-dried product and the marketed fast-release tablets. Conclusions: This research demonstrates that preparation of liquitablet in combination with freeze-drying has a significantly positive effect in improving the in vitro dissolution rate of lornoxicam.

Background/Objectives: The melt-spinning process has seen limited application in the pharmaceutical industry. However, nano- and microfibrous structures show significant potential for novel drug delivery systems, due to their high specific surface area. To facilitate broader adoption in pharmaceutical technology, critical parameters influencing fiber quality and yield must be investigated. In this study, we aimed to develop an isomalt-based microfibrous carrier system for active pharmaceutical ingredients. Methods: The effects of different isomalt compositions—specifically, varying ratios of GPS (6-O-α-d-glucopyranosyl-d-sorbitol) and GPM (1-O-α-d-glucopyranosyl-d-mannitol)—as well as key process parameters, were systematically investigated to optimize fiber formation. The prepared fibers underwent different treatments. Morphological changes were monitored with a microscope, and microstructural changes were studied using a differential scanning calorimeter and X-ray diffractometer. The macroscopic behavior of the fibers was evaluated by image analysis under monitored conditions. Results: Statistical analysis was used to determine the optimal setting to produce isomalt-based fibers. We found that storage over ethanol vapor has a positive effect on the stability of the fibers. We successfully prepared ibuprofen sodium-containing fibers that remained stable after alcohol treatment and enabled drug release within 15 s. Conclusions: It was found that the applied GPS:GPM isomalt ratio significantly influenced fiber formation and that storage over ethanol positively influenced the processability and stability of the fibrous structure. An isomalt-based microfibrous system with advantageous physicochemical and structural properties was successfully developed as a potential drug carrier. The system is also resistant to the destructive effects of ambient humidity, enabling preparation of suitable dosage forms. Full article
