Fabrication and application of targeted ciprofloxacin nanocarriers for the treatment of chronic bacterial prostatitis. Int J Pharm X 2024; 7:100247. [PMID: 38706465 PMCID: PMC11066576 DOI: 10.1016/j.ijpx.2024.100247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 04/11/2024] [Accepted: 04/11/2024] [Indexed: 05/07/2024] Open
Abstract
Pathogenic bacteria cause chronic bacterial prostatitis (CBP). CPB is characterized by urinary tract infection and persistence of pathogenic bacteria in prostatic secretion. Owing to poor blood supply to the prostate gland and limited drug penetration, CBP treatment is difficult. Transferosomes are ultradeformable vesicles for nanocarrier applications, which have become an important area of nanomedicine. Such carriers are specifically targeted to the pathological area to provide maximum therapeutic efficacy. It consists of a lipid bilayer soybean lecithin phosphatidylcholine (PC), an edge activator Tween 80 with various ratios, and a chloroform/methanol core. Depending on the lipophilicity of the active substance, it can be encapsulated within the core or among the lipid bilayer. Due to their exceptional flexibility, which enables them to squeeze themselves through narrow pores that are significantly smaller than their size, they can be a solution. One formulation (Cipro5 PEG) was selected for further in vitro analysis and was composed of phosphatidylcholine (PC), Tween 80, and polyethylene glycol-6 stearate (PEG-6 stearate) in a ratio of 3:3:1 in a chloroform/methanol mixture (1:2 v/v). In vitro, the results showed that PEGylated transferosomes had faster drug release, higher permeation, and increased bioavailability. The transferosomes were quantified with a particle size of 202.59 nm, a zeta potential of-49.38 mV, and a drug entrapment efficiency of 80.05%. The aim of this study was to investigate drug targeting. Therefore, Monoclonal antibody IgG was coupled with Cipro5 PEG, which has specificity and selectivity for conjugated nanoparticles. In vivo, a total of twenty-five adult Wistar rats were obtained and randomly divided into 5 groups, each of 5 rats at random: the control group, blank group, positive control group, Cipro 5PEG group, and Cipro 5PEG coupled with IgG antibody group. The cytokines levels (IL-1β, IL-8, and TNF-α) in the serum were detected by analysis kits. Compared with the control group, treatment with Cipro 5PEG coupled with the IgG antibody could significantly inhibit cytokines, according to histological analysis. Cipro 5PEG, coupled with the IgG antibody group, reduced prostate tissue inflammation. Hence, our results show a promising approach to delivering antibiotics for the targeted therapy of CBP.

Abstract
Crosslinked poly(vinyl alcohol) particles were prepared by the addition of glutaraldehyde into a PVA methanol/water solution in the presence of 0.2 N sulphuric acid. The polymer solution was dispersed in mineral oil in a jacketed vessel, with the aid of a six-blade impeller. Spherical crosslinked particles in the size range 30-80 microns were obtained by varying the degree of agitation or/and the amount of suspending agent. The crosslinked particles, after washing and drying, were placed into a protease enzyme solution for loading. The enzyme-containing water-swollen particles were subsequently removed from the solution and the enzyme release kinetics determined by a UV spectrophotometer. The influence of the degree of crosslinking, ionic strength, pH, particle size, and degree of hydrophilicity of the polymer on the enzyme activity was retained during the adsorption-desorption studies. The release behaviour of enzymes from crosslinked PVA particles exhibited a biphasic kinetic model, with an initial fast release followed by a much slower release rate.

Abstract
Human serum albumin microspheres were prepared with a series of barbiturates by the thermal denaturation method. The barbiturates were of similar general physicochemical properties but different partition coefficients. The total drug content of microspheres was dependent on the partition coefficient, and an increase in the partition coefficient caused a decrease in the drug content of finished microspheres due to drug migration to the outer organic phase during preparation. The ensemble drug release from microspheres was followed by the paddle method and by potentiometric titration with a pH-stat. Nonlinear regression analysis showed the best fit for the spherical Higuchi equation, especially first-order kinetics (biphasic). The drug partition coefficient affected the release in such a way that drugs with higher partition coefficients were released faster and to a greater extent than those with lower coefficients.

Abstract
Release rates from BSA microspheres prepared from various conditions are analysed using a previously reported equation expressing the first-order release rate constant. The permeability constants calculated applying the equation on experimental release rates are in good agreement with the constants measured from permeation studies using planar membrane, for various preparation conditions. It is shown that the equation expressing the first-order release rate constant is valid more extensively. The permeability constant varies depending on the preparation conditions, and the reason for variation is shown clearly to be the difference in degree of swelling of the polymer. It was found from regression analysis that there is relatively simple correlation between unknown parameters of the equation and the preparation conditions. Release rate constants can be calculated applying the equation on the known parameters and the estimated values of the unknown parameters from the correlation. Good agreement was found between the calculated values and experimental ones; therefore, at least as far as we examined here, the release rate constant of the microsphere can be estimated from the preparation conditions.
