Administrative structure of drug demand reduction and the way in which involved organizations interact with each other has been neglected by researchers, policy makers, and administrators at the national level and even in international institutions in this field. Studying such structures in different countries can reveal their attributes and features. In this study, key experts from the addictive behavior department of St George's University of London and a group of Iranian specialists in the field of drug demand reduction first wrote on a sheet the name of organizations that are in charge of drug demand reduction. Then, via teamwork, they drew the connections between the organizations and compared the two charts to assess the relations between the member organizations. In total, 17 features of efficient structure were obtained as follow: multi-institutional nature, collaborative inter-institutional activities, clear and relevant inter-institutional and intra-institutional job description, the ability to share the experiences, virtual institutions activity, community-based associations activity, mutual relationships, the existence of feedback sys-tems, evaluation, changeability, the ability to collect data rapidly, being rooted in community, flexibility at the local and regional levels, connection with research centers, updated policymaking, empowering the local level, and seeking the maximum benefit and the minimum resources. Recognizing the characteristics of substance related organizations in various countries could help policy makers to improve drug demand reduction structures and to manage the wide-spread use of psychoactive substances more effectively.

System-level wearable electronics require to be flexible to ensure conformal contact with the skin, but they also need to integrate rigid and bulky functional components to achieve system-level functionality. As one of integration methods, folding integration offers simplified processing and enhanced functionality through rigid-soft region separation, but so far, it has mainly been applied to modality of electrical sensing and stimulation. This paper introduces a vialess heterogeneous skin patch with multi modalities that separates the soft region and strain-robust region through folded structure.

Background: On demand, topical PrEP is desired by those preferring episodic, nonsystemic PrEP. PC-1005 gel (MIV-150, zinc, and carrageenan) exhibits in vitro antiviral HIV-1, human papillomavirus (HPV), and herpes simplex virus type 2 (HSV-2) activity, attractive for a multipurpose prevention technology candidate. We evaluated the safety, pharmacokinetics, and antiviral effect of rectally applied PC-1005.

Hypoxia, a condition that enhances tumor invasiveness and metastasis, poses a significant challenge for diverse cancer therapies. There is a pressing demand for hypoxia-responsive nanoparticles with integrated photodynamic functions in order to address the aforementioned issues and overcome the reduced efficacy caused by tumor hypoxia. Here, we report a hypoxia-responsive supramolecular nanoparticle SN@IR806-CB consisting of a dendritic drug-drug conjugate (IR806-Azo-CB) and anionic water-soluble [2]biphenyl-extended-pillar[6]arene modified with eight ammonium salt ions (AWBpP6) the synergy of π-π stacking interaction, host-guest complexation, and hydrophobic interactions for synergistic photothermal therapy (PTT), photodynamic therapy (PDT), and chemotherapy (CT; , PTT-PDT-CT).

Background: Nanosuspension has emerged as an effective, lucrative, and unequalled approach for efficiently elevating the dissolution and bioavailability of aqueous soluble drugs. Diverse challenges persist within this domain, demanding further comprehensive investigation and exploration.
Objective: This study aims to design, develop, optimise formulation and process variables, and characterise the stabilised aqueous dissolvable nanosuspension using chlorthalidone as a BCS class- IV drug.

The frozen storage of biopharmaceuticals brings new challenges to the primary packaging material. Due to an increasing demand and the downsides of standard type I glass vials, such as vial breakage, novel vial types for special applications of parenteral drug products have been introduced to the market in the past years. Mechanical stresses due to dimensional changes experienced during freezing and thawing could change the material properties, hence affecting the interaction with the drug product stored in the vial or functionality such as overall integrity.
