Natural goods contain a wealth of medicinally active chemicals used to treat a wide range of skin problems, including infections, inflammation, and damage caused by UV light and pollution. Cosmeceuticals are a mix of cosmetic and medical chemicals. Based on their main ingredients, they can be used for both beauty and health purposes. Many people think that natural goods are a great way to obtain cosmeceuticals. It has strong antiinflammatory, antibacterial, anti-cancer, and protective properties. The benefit for the skin has been said to be the most interesting. GA and its products have been used a lot as an adjuvant in many therapeutic formulations, as an alternative to hydro-cortisone in children with atopic dermatitis and other skin diseases, and as an ingredient in cosmetics because they are good for humans. GA is GRAS (generally recognized as safe) by the US Food and Drug Administration. Oxidative stress, which happens when too many free radicals build up, is the main cause of many skin diseases that get worse over time, like aging. Polyphenols, including gallic acid, represent a significant category of naturally occurring antioxidants. They have emerged as potent antioxidants suitable for incorporation into active makeup products. Recent advancements include patent filings related to novel applications and formulations of Gallic acid in cosmetic science that highlight innovative delivery systems, such as nano-formulations enhancing stability and efficacy, as well as its synergistic combinations with other active ingredients to address targeted skin concerns like pigmentation, aging, and sensitivity which meets the demands of modern consumers.</p>","PeriodicalId":94352,"journal":{"name":"Recent advances in drug delivery and formulation","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144182899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modified-release formulations, including chewable tablets, transdermal patches, and osmotic-controlled release tablets, offer improved treatment adherence and overall quality of life. Understanding the pathophysiology involves neuroimaging studies that reveal alterations in brain regions rich in dopamine receptors.

Different drug delivery systems, such as extended-release chewable tablets, transdermal patches, and OROS formulations, provide diverse options for individual needs. The advent of innovative formulations like methylphenidate hydrochloride extendedrelease oral suspension (Quillivant ER) and methylphenidate hydrochloride multilayer extendedrelease capsules (Aptensio XR) addresses challenges in pediatric medication administration.

An implantable drug delivery system (IDDS) presents an attractive alternative: long-term, continuous drug release improves therapeutic efficacy while minimizing toxicity and side effects. IDDS, first presented in the 1930s as subcutaneous hormone pellets, have gained much attention recently in drug delivery due to their controlled release of drugs in a localized and sustained manner. In systemic treatments, drugs administered through IDDS evade first-pass metabolism and enzymatic degradation within the gastrointestinal tract, therefore enhancing drug bioavailability. The most suitable properties of IDDS are its application with drugs that have poor stability or solubility in oral formulations. Even though implantation is invasive, the benefits of infrequent administration, higher patient compliance, and being able to discontinue therapy when side effects are present far outweigh the disadvantages. Today, IDDSs are used in a myriad of therapeutic areas: contraception, chemotherapy, and pain management, to name a few.

Low solubility is further accompanied by slow dissolution and poor bioavailability, which in turn leads to unpredictability in terms of both bioavailability and toxicity. Therefore, a significant amount of exertion is necessary to enhance solubility, dissolution, and eventually bioavailability. Additionally, to enhance the solubility properties and amorphous stability of BCS Class II medications and ultimately increase drug bioavailability, coamorphization has emerged as a promising strategy. Co-amorphous solid dispersions (CASD) are multi-component single-phase amorphous solid dispersions comprising two or more small molecules (usually known as co-formers) that might be a combination of drug-drug or drug-excipients. The selection of appropriate co-formers is critical, and the surface properties of co-amorphous formulations must be carefully evaluated, as they influence physical and chemical stability in addition to dissolution performance. Scaling up and processing co-amorphous formulations into the final dosage forms presents challenges that need to be addressed. This review will largely concentrate on the challenges, improvements, and innovations in physicochemical properties, biological characterization, and advancements of co-amorphous systems. This review will also furnish a comprehensive explanation of both established and emerging approaches utilized in the estimation of physicochemical attributes and characterization of CASD (in vitro and in vivo).
