Background: Polymeric nanomaterials with size ranging from 10 to 1000 nm are one of the most widely used types of nanoparticles with ideal properties in the drug delivery systems. Here, we decided to systematically review the antihypertensive effects of polymeric nanomaterials in vitro, in vivo, and clinical trials. Methods: The present review was conducted based on the 06- PRISMA guideline; whereas five English databases, including Scopus, PubMed, Web of Science, EMBASE, and Google Scholar without time limitation were used for searching the publications related to antihypertensive effects of natural and synthetic polymeric nanoparticles. Results: The results demonstrated that among 1701 papers, 25 papers including 11 in vitro (44%), 6 in vivo (24%), 7 in vitro / in vivo (28%), and 1 in vitro / ex vivo (4%) up to 2020, met the inclusion criteria for discussion in this systematic review. The most used nanoparticles poly-(lactic-co-glycolic) acid nanoparticle (PLGANPs) (7, 29.2%), chitosan based nanoparticles (6, 25%), followed by polylactide acid nanoparticles (5, 20.8%). Conclusion: We concluded that the high potency of polymeric nanoparticles in the drug delivery system for hypertension treatment. Although the accurate mechanisms are not fully understood; however, some mechanisms such as sustained release forms with increased bioavailability, increasing oral bioavailability and improve the oral and non-oral absorption, counteracting excessive superoxide and decreasing blood pressure, etc can be related these nanoparticles.

Background: Diclofenac sodium (DS) injection is widely used in the management of acute or chronic pain and inflammatory diseases. It incorporates 20 % w/v Transcutol-P as a solubilizer to make the stable injectable formulation. However, the use of Transcutol-P in high concentration leads to adverse effects such as severe nephrotoxicity, etc. Some advancements resulted in the formulation of an aqueous based injectable but that too used benzyl alcohol reported to be toxic for human use. Objective: To develop an injectable self-micro emulsifying drug delivery system (SMEDDS) as a novel carrier of DS for prompt release with better safety and efficacy. Methods: A solubility study was performed with different surfactants and co-surfactants. The conventional stirring method was employed for the formulation of SMEDDS. Detailed in vitro characterization was done for different quality control parameters. In vivo studies were performed using Wistar rats for pharmacokinetic evaluation, toxicological analysis, and analgesic activity. Results: The optimized formulation exhibited good physical stability, ideal globule size (156±0.4 nm), quick release, better therapeutics, and safety, increase in LD50 (221.9 mg/kg) to that of the commercial counterpart (109.9 mg/kg). Further, pre-treatment with optimized formulation reduced the carrageenan-induced rat paw oedema by 88±1.2 % after 4 h, compared to 77±1.6 % inhibition with commercial DS formulation. Moreover, optimized formulation significantly (p<0.05) inhibited the pain sensation in the acetic-acid induced writhing test in mice compared to its commercial equivalent with a better pharmacokinetic profile. Conclusion: The above findings confirmed that liquid SMEDDS could be a successful carrier for the safe and effective delivery of DS

Globule Size

Hypertension is a cardiovascular disease that needs long-term medication. Oral delivery is the most common route for the administration of drugs. The present research is to develop piperine self-nanoemulsifying drug delivery system (PE-SNEDDS) using glyceryl monolinoleate (GML), poloxamer 188, and transcutol HP as oil, surfactant, and co-surfactant, respectively. The formulation was optimized by three-factor, three-level Box-Behnken design. PE-SNEDDs were characterized for globule size, emulsification time, stability, in-vitro release, and ex-vivo intestinal permeation study. The optimized PE-SNEDDS (OF3) showed the globule size of 70.34 ± 3.27 nm, percentage transmittance of 99.02 ± 2.02%, and emulsification time of 53 ± 2 s Finally, the formulation OF3 was transformed into solid PE-SNEDDS (S-PE-SNEDDS) using avicel PH-101 as adsorbent. The reconstituted SOF3 showed a globule size of 73.56 ± 3.54 nm, PDI of 0.35 ± 0.03, and zeta potential of −28.12 ± 2.54 mV. SEM image exhibited the PE-SNEDDS completely adsorbed on avicel. Thermal analysis showed the drug was solubilized in oil, surfactant, and co-surfactant. S-PE-SNEDDS formulation showed a more significant (p < 0.05) release (97.87 ± 4.89% in 1 h) than pure PE (27.87 ± 2.65% in 1 h). It also exhibited better antimicrobial activity against S. aureus and P. aeruginosa and antioxidant activity as compared to PE dispersion. The in vivo activity in rats exhibited better (p < 0.05) antihypertensive activity as well as 4.92-fold higher relative bioavailability than pure PE dispersion. Finally, from the results it can be concluded that S-PE-SNEDDS might be a better approach for the oral delivery to improve the absorption and therapeutic activity.

A key challenge for nanoparticles-based drug delivery system is to achieve manageable drug release in tumour cell. In this study, a versatile system combining photothermal therapy and controllable drug release for tumour cells using temperature-sensitive block copolymer coupled Au NRs@SiO2 is reported. While the Au NRs serve as hyperthermal agent and the mesoporous silica was used to improve the drug loading and decrease biotoxicity. The block copolymer acted as “gatekeeper” to regulate the release of model drug (Doxorubicin hydrochloride, DOX). Through in vivo and in vitro experiments, we achieved the truly controllable drug release and photothermal therapy with the collaborative effect of the three constituents of the nanocomposites. The reported nanocomposites pave the way to high-performance controllable drug release and photothermal therapy system.
