The main route to stabilise co-amorphous systems is to increase excipient load either in the co-amorphous formulation or <em>via</em> an additional excipient, creating a ternary amorphous system. Increasing excipient load in a formulation can have disadvantages such as producing large oral dosage forms. In this work, the impact of spray drying process parameters on the formation and short-term stability of a drug–drug co-amorphous mixture in the absence of any excipients is investigated. A 9-point design of experiments (DoE) was conducted to assess the impact of atomising gas flowrate and feed flowrate on the co-amorphous formation and stability. It was found that when the outlet temperature was fixed at 50 °C, the atomising gas flowrate had a more significant effect on the physical stability of the co-amorphous mixture than the feed flowrate. Monitoring the stability of formulations at accelerated stability conditions (40 °C per 75% relative humidity) showed that the co-amorphous systems produced at higher atomising gas flowrates, with smaller droplet sizes and subsequent particle sizes, exhibited a higher stability than those produced at lower atomising gas flowrates. Co-amorphous systems produced at the higher atomising gas flowrates remained stable for the 3-month stability testing period demonstrating that the co-amorphous physical stability can be controlled by optimising the spray drying process. The results presented in this study have significant implications for producing co-amorphous drug delivery systems with a high physical stability without the addition of excipients by spray drying.</p>","PeriodicalId":101141,"journal":{"name":"RSC Pharmaceutics","volume":" 1","pages":" 102-113"},"PeriodicalIF":0.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/pm/d4pm00257a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Symptoms often appear between the ages of 35 and 60, with varying severity caused by periods of remission and exacerbation. In addition, children under the age of 16 might develop juvenile rheumatoid arthritis (JRA). According to a 2021 CDC poll, the World Health Organization estimates that 14 million people worldwide suffer with RA, with 0.92% of India's adult population afflicted. Non-steroidal anti-inflammatory drugs (NSAIDs), synthetic disease-modifying anti-rheumatic drugs (sDMARDs), and biological DMARDs are among the current therapeutic interventions. However, these therapies frequently exhibit limitations such as systemic side effects, short biological half-lives, erratic absorption, and frequent dosing regimens. Recent advances in ligand-based nanotechnology have introduced ligands such as folic acid and sialic acid that improve the targeted delivery when conjugated with nanoparticles. This approach has demonstrated efficacy in improving therapeutic outcomes while alleviating the side effects associated with conventional drug delivery systems. This review highlights the key molecular targets in RA, including T cells, B cells, and TNF-α, while exploring novel ligand-based active targeting strategies as innovative therapeutic avenues. Furthermore, it gives in-depth insights into critical molecular targets and their corresponding ligands, emphasizing the rising importance of ligand-based nanotechnology in the development of targeted drug therapy for autoimmune illnesses such as RA. The findings show the potential for these technologies to revolutionize RA therapy by improving medication specificity and reducing side effects <em>via</em> precise novel targeting mechanisms.</p>","PeriodicalId":101141,"journal":{"name":"RSC Pharmaceutics","volume":" 1","pages":" 19-43"},"PeriodicalIF":0.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/pm/d4pm00133h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
