Polyvinyl alcohol-based capsule shells manufactured by injection molding as ready-to-use moisture barriers for the development of delivery systems. Int J Pharm 2024; 661:124373. [PMID: 38909921 DOI: 10.1016/j.ijpharm.2024.124373] [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: 05/02/2024] [Revised: 06/14/2024] [Accepted: 06/20/2024] [Indexed: 06/25/2024]
Abstract
In this work, feasibility of injection molding was demonstrated for manufacturing capsule shells. 600 µm-thick prototypes were successfully molded with pharmaceutical-grade low-viscosity polyvinyl alcohols (PVAs), possibly added with a range of different fillers. They showed reproducible weight and thickness (CV < 2 and 5, respectively), compliant behavior upon piercing (holes diameter analogous to the reference), tunable release performance (immediate and pulsatile), and moisture protection capability. To assess the latter, an on-line method relying on near infrared spectroscopy measurements was set-up and validated. Based on the data collected and considering the versatility IM would provide for product shape/thickness/composition, PVA-based molded shells could help widening the portfolio of ready-to-use capsules, representing an interesting alternative to those commercially available. Indeed, these capsules could be filled with various formulations, even those with stability issues, and intended either for oral administration or for pulmonary delivery via single-dose dry powder inhalers.

Kruk K, Winnicka K. Hard Gelatin Capsules with Alginate-Hypromellose Microparticles as a Multicompartment Drug Delivery System for Sustained Posaconazole Release. Int J Mol Sci 2024; 25:7116. [PMID: 39000223 PMCID: PMC11241651 DOI: 10.3390/ijms25137116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2024] [Revised: 06/24/2024] [Accepted: 06/26/2024] [Indexed: 07/16/2024] Open
Abstract
Microparticles as a multicompartment drug delivery system are beneficial for poorly soluble drugs. Mucoadhesive polymers applied in microparticle technology prolong the contact of the drug with the mucosa surface enhancing drug bioavailability and extending drug activity. Sodium alginate (ALG) and hydroxypropyl methylcellulose (hypromellose, HPMC) are polymers of a natural or semi-synthetic origin, respectively. They are characterized by mucoadhesive properties and are applied in microparticle technology. Spray drying is a technology employed in microparticle preparation, consisting of the atomization of liquid in a stream of gas. In this study, the pharmaceutical properties of spray-dried ALG/HPMC microparticles with posaconazole were compared with the properties of physical mixtures of powders with equal qualitative and quantitative compositions. Posaconazole (POS) as a relatively novel antifungal was utilized as a model poorly water-soluble drug, and hard gelatin capsules were applied as a reservoir for designed formulations. A release study in 0.1 M HCl showed significantly prolonged POS release from microparticles compared to a mixture of powders. Such a relationship was not followed in simulated vaginal fluid (SVF). Microparticles were also characterized by stronger mucoadhesive properties, an increased swelling ratio, and prolonged residence time compared to physical mixtures of powders. The obtained results indicated that the pharmaceutical properties of hard gelatin capsules filled with microparticles were significantly different from hard gelatin capsules with mixtures of powders.

Carbohydr Polym 2024; 328:121706. [PMID: 38220341 DOI: 10.1016/j.carbpol.2023.121706] [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: 10/07/2023] [Revised: 11/30/2023] [Accepted: 12/15/2023] [Indexed: 01/16/2024]
Abstract
The quality of polysaccharide-based films and hard capsules is often affected by changes in relative humidity, manifesting as unstable water content, and changes in mechanical strength that make them brittle or soft. Herein, carboxyl-modified nanocellulose (cNC) was prepared and used as a new component to successfully improve the moisture resistance of cNC/pullulan/high-acyl gellan bio-nanocomposite hard capsules (NCPGs). Homogenously dispersed cNC in the pullulan/high-acyl gellan matrix could render the formation of more hydrogen bonds that provided additional water-binding sites and limited the free movement of pullulan and high-acyl gellan molecular chains within NCPGs. This contributed to a decreased amount of pooling adsorption water and an increased amount of Langmuir adsorption water in NCPGs, as compared to pullulan/high-acyl gellan hard capsules (PGs) without cNC. Therefore, the equilibrium moisture content (EMC) values of NCPGs decreased at 83 % relative humidity and increased at 23 % relative humidity compared to those of PGs. Together with enhanced mechanical and barrier properties, NCPGs effectively protected encapsulated amoxicillin and probiotic powder from changes in the outside humidity. Additionally, NCPGs exhibited faster drug release. This study presents a new mechanism and strategy for fabricating films and hard capsules with enhanced stability against moisture variation.

Abstract
Using plant-based polysaccharide gels to produce hard capsules is a novel application of this technology in the medicinal field, which has garnered significant attention. However, the current manufacturing technology, particularly the drying process, limits its industrialization. The work herein employed an advanced measuring technique and a modified mathematical model to get more insight into the drying process of the capsule. Low field magnetic resonance imaging (LF-MRI) technique is adopted to reveal the distribution of moisture content in the capsule during drying. Furthermore, a modified mathematical model is developed by considering the dynamic variation of the effective moisture diffusivity (Deff) according to Fick's second law, which enables accurate prediction of the moisture content of the capsule with a prediction accuracy of ±15%. The predicted Deff ranges from 3 × 10-10 to 7 × 10-10 m2·s-1, which has an irregular variation with a time extension. Moreover, as temperature increases or relative humidity decreases, there is an increased acceleration of moisture diffusion. The work provides a fundamental understanding of the drying process of the plant-based polysaccharide gel, which is crucial for enhancing the industrial preparation of the HPMC-based hard capsules.

Polymers (Basel) 2023; 15:polym15102247. [PMID: 37242822 DOI: 10.3390/polym15102247] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Revised: 05/05/2023] [Accepted: 05/08/2023] [Indexed: 05/28/2023] Open
Abstract
The plasticizer is crucial in the plant-based soft capsule. However, meeting the quality requirements of these capsules with a single plasticizer is challenging. To address this issue, this study first investigated the impact of a plasticizer mixture containing sorbitol and glycerol in varying mass ratios and the performance of the pullulan soft film and capsule. The multiscale analysis demonstrates that the plasticizer mixture exhibits superior effectiveness in enhancing the performance of the pullulan film/capsule compared to a single plasticizer. Furthermore, thermogravimetric analysis, Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy indicate that the plasticizer mixture enhances the compatibility and thermal stability of the pullulan films without altering their chemical composition. Among the different mass ratios examined, a 15:15 ratio of sorbitol to glycerol (S/G) is identified as the most optimal, leading to superior physicochemical properties and meeting the requirements for brittleness and disintegration time set by the Chinese Pharmacopoeia. This study provides significant insights into the effect of the plasticizer mixture on the performance of pullulan soft capsules and offers a promising application formula for future use.

Abstract
Detection of bovine and porcine in gelatin-based products is important as species fraud and product mislabeling may have a detrimental impact on customers who have health, ethical, and religious concerns about animal products. The duplex droplet digital PCR (ddPCR) assay using double-quenched probes has been developed for quantification and detection of porcine and bovine DNA in gelatin capsules. A DNA mixture derived from gelatin was found to have a limit of detection as low as 0.001 ng/µl for porcine samples and 0.01 ng/µl for bovine samples. DNA from 12 other distinct species was tested with the bovine and porcine probes, showing high specificity for this method. The test was validated using fifty-five commercial supplement and pharmaceutical capsules, of which 17 were positive for bovine and/or porcine DNA. This study shows that the duplex ddPCR is reliable for routine analysis in the identification of bovine and porcine origins for gelatin capsules.

Abstract
Pullulan, an α-glucan polysaccharide, is colorless, odorless, non-toxic, non-carcinogenic, highly biocompatible, edible and biodegradable in nature. The long chains of glucopyranose rings in pullulan structure are linked together by α-(1 → 4) and α-(1 → 6) glycosidic linkages. The occurrence of both glycosidic linkages in the pullulan structure contributes to its distinctive properties. The unique structure of pullulan makes it a potent candidate for both pharmaceutical and cosmeceutical applications. In pharmaceuticals, it can be used as a drug carrier and in various dosage formulations. It has been widely used in drug targeting, implants, ocular dosage forms, topical formulations, oral dosage forms, and oral liquid formulations, etc. Pullulan can be used as a potential carrier of active ingredients and their site-specific delivery to skin layers for cosmeceutical applications. It has been extensively used in cosmeceutical formulations like creams, shampoo, lotions, sunscreen, facial packs, etc. The current review highlights applications of pullulan in pharmaceutical and cosmeceutical applications.

Abstract
Certain patient populations receive insufficient medicinal treatment due to a lack of commercially available products. The number of approved veterinary products is limited, making animals a patient population with suboptimal medicinal treatments available. To answer to this unmet need, compounding and off-label use of human-marketed products are practiced. Both of which have a significant risk of preparation errors. Hence, there is a dire demand to find and implement a more automated approach to the accurate, precise, and rapid production of veterinary dosage forms close to the point-of-care. This study aimed to assess the use of semi-solid extrusion-based 3D printing for the preparation of tailored doses of theophylline in the form of a chewable dosage form suitable for veterinary use. This study proved that semi-solid extrusion-based 3D printing could successfully be utilized to manufacture pet-friendly, chewable theophylline-loaded tablets. The prepared dosage forms showed a high correlation (R2 = 0.9973) between the designed size and obtained drug amount and met the USP and Ph. Eur. content uniformity criteria. Furthermore, the stability study showed the dosage form being stable and able to be used for up to three months after printing.

Abstract
One of the major impediments to drug development is low aqueous solubility and thus poor bioavailability, which leads to insufficient clinical utility. Around 70–80% of drugs in the discovery pipeline are suffering from poor aqueous solubility and poor bioavailability, which is a major challenge when one has to develop an ocular drug delivery system. The outer lipid layer, pre-corneal, dynamic, and static ocular barriers limit drug availability to the targeted ocular tissues. Biopharmaceutical Classification System (BCS) class II drugs with adequate permeability and limited or no aqueous solubility have been extensively studied for various polymer-based solubility enhancement approaches. The hydrophilic nature of cellulosic polymers and their tunable properties make them the polymers of choice in various solubility-enhancement techniques. This review focuses on various cellulose derivatives, specifically, their role, current status and novel modified cellulosic polymers for enhancing the bioavailability of BCS class II drugs in ocular drug delivery systems.

Abstract
A strategy for preparation of self-reinforced starch films for use as hard capsule material is introduced. In this study, the hydroxypropylated-crosslinked potato starch (HCPS) was prepared and used to reinforce the hydroxypropylated-hydrolyzed potato starch (HHPS) films. The paste properties of starch samples and the morphology of starch films were investigated by a rapid visco analyzer (RVA) and scanning electron microscope (SEM), respectively. It was found that the matrix/particle interface was greatly improved after the hydroxypropylation of crosslinked starch. The strain and toughness of the starch composite films were increased by about 30% and 50% after addition of 10 wt% HCPS particles, respectively. In addition, the self-reinforced starch film also had good oxygen barrier property, with its oxygen permeating coefficient (OPC) at 5.09 × 10-12 cm3·cm/cm2·s·cmHg (50% RH). The fragmentation rate of starch capsules has also decreased, indicating it is an alternative material for the preparation of hard capsules.

J Pharm Sci 2021; 110:3829-3837.

Abstract
Individualized drug delivery improves drug efficacy and safety for patients. To implement individualized drug delivery, patient-specific tailored dosages produced on a small scale are needed. However, current pharmaceutical manufacturing is not suitable for personalized dosage forms. Although convenient to deliver various drugs, current gelatin capsules using animal collagen protein have many limitations, such as releasing drugs too fast and incompatibility with some diets. In contrast, 3D printed capsules have great potential to advance individualized treatments. In this paper, we 3D printed and tested non-animal-based capsule shells for the delivery of acetaminophen. Capsule shells were composed of poly(vinyl) alcohol (PVA) and PVA blends with 5-25% hydroxypropyl methylcellulose (HPMC). Dissolution of acetaminophen when delivered in -hese capsule shells was tested using a USP dissolution test apparatus 2 (paddle type) at gastric pH. The novel shells were compared to each other and to commercially available hard gelatin capsules. Dissolution results show that acetaminophen when delivered in 3D printed capsules was slower than when delivered by gelatin capsules. Increasing the percentage of HPMC in the blend further delayed its release and dissolution. This delay could potentially increase the efficacy and reduce the side effects of acetaminophen. These shells also offer a non-animal-based alternative to gelatin capsules. Furthermore, 3D printing of capsule shells with specific polymer blends may be useful for patient-specific therapy in compounding pharmacies across the country.

Abstract
In order to explore the effect of the hollow capsule material formulation on the capsule glue and film formation, this study used hydroxypropylmethylcellulose (HPMC), carrageenan, KCl and Tween 80 as raw materials to determine the production of HPMC hollow capsules suitable formula. The optimal process conditions are as follows: the proportions of HPMC, carrageenan, KCl and Tween 80 in the solvent (purified water) are 18% (m:V), 0.7% (m:V), 0.07% (m:V) and 0.018% (V:V), respectively. Under this condition, the viscosity of the resulting solution, glue solidification temperature and gel strength were medium. The resulting film has low hygroscopicity, good solubility, optical properties and mechanical properties. This research can provide data support for the precise formulation and industrial production of HPMC hollow plant capsules.

Abstract
The green hard capsules were prepared with corn nano-starch (CNS) and cellulose nanocrystal (CNC) in this study, the glycerol and carrageenan were used as plasticizer and gelling agent in the CNS/CNC gel solution, respectively. The capsule-films with different CNC content were prepared by casting method, and the dipping method was used in preparation of the corresponding capsules. The compatibility of CNS/CNC capsules was analyzed by Fourier Transform Infrared spectroscopy (FTIR) and X-Ray Diffraction (XRD), and the morphology of the capsules was analyzed by Scanning Electron Microscopy (SEM). The results showed that the tensile strength of the CNS based capsule-film was significantly improved with the addition of CNC. When the content of CNC was 6.0%, the tensile strength increased by 238.10%. The transparency of the capsule with different CNC contents was slightly reduced, but was greater than 87.0%. The loss on drying of CNS/CNC capsule was between 12.87% and 15.03%, and it could be completely dissolved in the artificial gastric juice within 6.0 min, which was in accordance with the provisions of Chinese Pharmacopoeia (2015).
