Chlorpromazine is an antipsychotic agent with poor aqueous solubility. Complexation with SBE(7)-beta-CD can aid intravenous delivery through increasing the apparent solubility of chlorpromazine. However, chlorpromazine has also been known to self-associate. This self-association can influence its capacity to interact with other chemical species, such as cyclodextrins. This study aimed to characterise the self-association and cyclodextrin binding properties of chlorpromazine, and the effect on pharmacokinetic parameters in rats when dosed with a SBE(7)-beta-CD containing formulation. Pharmacokinetic studies of chlorpromazine in the presence and absence of SBE(7)-beta-CD were undertaken in rats. The binding constant of SBE(7)-beta-CD and chlorpromazine was studied relative to chlorpromazine concentration via fluorescence. The self-association of chlorpromazine was studied by fluorescence and UV-visible spectrophotometry. Urinary excretion of intact chlorpromazine increased in the presence of SBE(7)-beta-CD. The SBE(7)-beta-CD binding constant of chlorpromazine is highly concentration dependent and the variation can be attributed to the self-association of chlorpromazine. The apparent binding constant of chlorpromazine is highest at pharmacologically relevant concentrations, providing an explanation for the significant increase in renal chlorpromazine excretion observed in rats.

Ferulic acid (FA) is a phenolic compound obtained naturally and is a versatile antioxidant identified for its potential in managing hypertension. However, its application is constrained due to its classification as a BCS Class IV moiety. To address this, we concentrated on improving its solubility and permeability by developing nanostructured lipid carriers (NLCs) of FA using emulsification probe sonication technique.

This study aimed to determine the association between chronic schizophrenia, extrapyramidal symptoms (EPSs), body composition, nutritional status, and dynapenia/sarcopenia. Data from 68 chronic patients with schizophrenia were analyzed using Spearman's rho correlation coefficients, Kruskal-Wallis test, Mann-Whitney U test, and Cramér's V statistics. Among the participants, 32.

Despite the various benefits of chlorpromazine, its misuse and overdose may lead to severe side effects, therefore, creating a user-friendly point-of-care device for monitoring the levels of chlorpromazine drug to manage the potential side effects and ensure the effective and safe use of the medication is highly desired. In this report, we have demonstrated a simple and scalable manufacturing process for the development of a 3D-printed conducting microneedle array-based electrochemical point-of-care device for the minimally invasive sensing of chlorpromazine. We used an inkjet printer to print the carbon and silver ink onto a customized 3D-printed ultrasharp microneedle array for the preparation of counter, working, and reference electrodes.

Persistent hiccups are rare but can serve as an early symptom of underlying conditions, including pulmonary infections and cerebrovascular disorders. This case highlights hiccups as a presenting symptom of bronchopneumonia in a hemodialysis patient and explores the effective use of chlorpromazine and Hange-koboku-to (HKT) as symptomatic therapies. Given the potential association of hiccups with neurological conditions, this case underscores the need for comprehensive diagnostic evaluation.

Background: Foreign language syndrome is a rare neuropsychiatric phenomenon typically following general anesthesia. To date, foreign language syndrome has not been associated with neuroleptic malignant syndrome (NMS) in the literature. This case aims to broaden the clinical understanding of NMS by presenting an atypical manifestation of foreign language syndrome and emphasizing the need for prompt recognition of such presentations for accurate diagnosis and management.
