Abstract
Background: Current therapy for pulmonary arterial hypertension (PAH) is unable to prevent progression of disease due to continuous infusions and multiple oral administrations. This resulted in the need of novel treatment which would target directly structural vascular changes that weaken blood flow through pulmonary circulation.
Objective: The objective of present study was to develop spray dried (SD) formulation for dry powder inhaler (DPI) with enhanced aerosol performance and lung deposition by using novel bioactive, andrographolide (AGP) and carrier, scleroglucan (SCLG) with improved antihypertensive activity. The SDAGP formulation was evaluated for physicochemical properties and in vitro/in vivo lung deposition. Further, antihypertensive activity was studied by monocrotaline (MCT) induced rat model.
Results: The SDAGP exhibited mean median aerodynamic diameter (MMAD) and fine particle fraction (FPF) of 3.37 ± 0.47 µm and 60.24 ± 0.98%. The in vivo absorption profile of final formulation reflected increased lung deposition of AGP at the end of 24 h with no signs of inflammation and toxicity. Moreover, SDAGP formulation confirmed enhanced antihypertensive activity.
Conclusion: The results proved use of AGP and SCLG as a novel bioactive and carrier with enhanced lung deposition and pulmonary antihypertensive activity.
Keywords: Andrographolide (AGP), dry powder inhaler (DPI), microparticles, pulmonary arterial hypertension (PAH), scleroglucan (SCLG), spray dried (SD).

Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
