The aim of this study is to unlock some of the physicochemical properties of ALBHCL that serve as a database for any future studies. A solubility study of ALBHCL was performed in different solvents. Also, photostability was tested in the solution and solid states, and the order of reaction and rate constant were calculated. In addition to the pH solubility relation, the pH-rate relation at different temperatures was also studied, and the profiles were constructed. A solubility study was also performed in different media for the purpose of optimizing suitable sink conditions for the in vitro dissolution testing of solid dosage forms. Solubility tests in multiple solvents and pH conditions revealed that the highest solubility was in DMSO, methanol, and chloroform, with acidic media yielding the maximum solubility but degrading at rather low pH levels. ALBHCL proved unstable at high temperatures and under light exposure, with varying stability across different pH levels. The optimal dissolution media for in vitro oral dosage form evaluation were determined, achieving sink conditions at pH levels of 6.8 and 4.5 with specific additives. This study enhances the existing database on ALBHCL’s physicochemical properties, emphasizing the importance of pH optimization in pharmaceutical processes and providing valuable insights into its pharmaceutical application.

of juice, consumed regularly by many individuals owing to its nutritional value, including fiber, vitamin C, and
antioxidants. Grapefruit juice (GFJ) compounds, mainly naringin, bergamottin, and 6,7-dihydroxybergamottin
(DHB), inhibit intestinal CYP3A4 enzymes, which are mediated by the metabolic processes of many drugs and result
in the interaction between GFJ and drugs that are CYP3A4 substrates when administered concomitantly. GFJ-drug
interaction is affected by several factors, including oral bioavailability, patient vulnerability, and factors related to
GFJ consumption, such as the amount of GFJ consumed and the interval between GFJ and drug administration.
Many drugs from different classes have the potential for interaction, including calcium channel blockers such as
felodipine, statins such as simvastatin, immunosuppressants, benzodiazepines such as midazolam, antihistamines
such as terfenadine, and many other drugs. Pharmacists have a strong medical background that makes them able to
predict grapefruit-drug interactions. Thus, they play a critical role in reducing the risk of GFJ-drug interactions by
advising and educating patients when dispensing prescribed and Over-the-counter (OTC) drugs

azelaic acid (AzA) for acne treatment. The systems tested for this purpose were deep eutectic systems
(DESs) prepared from choline chloride (CC), malonic acid (MA), and PEG 400. Three CC to MA
and eight different MA: CC: PEG400 ratios were tested. The physical appearance of the tested
formulations ranged from solid and liquid to semisolid. Only those that showed liquid formulations
of suitable viscosity were considered for further investigations. A eutectic mixture made from MA:
CC: PEG400 1:1:6 (MCP 116) showed the best characteristics in terms of viscosity, contact angle,
spreadability, partition coefficient, and in vitro diffusion. Moreover, the MCP116 showed close
rheological properties to the commercially available market lead acne treatment product (Skinorin®).
In addition, the formula showed synergistic antibacterial activity between the MA moiety of the DES
and the AzA. In vitro diffusion studies using polyamide membranes demonstrated superior diffusion
of MCP116 over the pure drug and the commercial product. No signs of skin irritation and edema
were observed when MCP116 was applied to rabbit skin. Additionally, the MCP116 was found to be,
physically and chemically, highly stable at 4, 25, and 40 ◦C for a one-month stability study

It has low solubility and dissolution rate and low oral bioavailability. This work aimed to improve efficacy by loading on ZSM-5 silica nanoparticles and testing the prepared delivery system on A-549 lung cancer cells. Methods: ZSM-5 was synthesized in the laboratory and different methods of loading GEF on the nanoparticles were used, then the system was characterized by X-ray diffraction, Fourier Transport Infra-Red (FTIR), and drug release and dissolution. Results and conclusion: GEF-loaded nanoparticles (NPs) showed prolonged release of GEF over 12 hours with an improved biological efficacy expressed by the decrease in IC50 compared to free GEF (P < 0.001) using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay. Also, there was a significant decrease in migration and colony formation ability of the GEF-loaded NPs on A-549 lung cancer cells. In conclusion, loading GEF onto ZSM-5 NPs resulted in a lower IC50 and improved biological action toward A-549 cells.

inhibitor commonly used for treating non-small-cell carcinoma (NSCLC). Given ALB’s low solubility and
bioavailability, complexation with β-cyclodextrin (βCD) and hydroxy propyl β-cyclodextrin (HPβCD)
was evaluated. Some of the different preparation methods used with varying ALB-to-CD ratios led to the
formation of complexes that were characterized using Fourier-Transform Infrared (FTIR) techniques and
Differential Scanning Calorimetry (DSC) to prove complex formation. The encapsulation efficiency was
also determined. The simulations were carried out for ALB’s interactions with βCD and HPβCD. This
study identified the most soluble complex (ALB–HPβCD; 1:2 ratio) and evaluated its dissolution. The
bioavailability of the ALB–HPβCD complex was evaluated in Wistar rats relative to free ALB. Pharmacokinetic profiles revealed increased Cmax (240 ± 26.95 ng/mL to 474 ± 50.07 ng/mL) and AUC0-48
(5946.75 ± 265 ng.h/mL to 10520 ± 310 ng.h/mL) with no change in the elimination rate constant. In
conclusion, the complexation of ALB–HPβCD manages to increase in vitro solubility, the dissolution rate,
and oral bioavailability, providing a favorable approach to improving ALB administration.

Enhancing carvedilol low solubility and dissolution rate would help in improving the efficiency of the tablet dosage form. In this study, different types of silica nanoparticle (NPs) (SBA-16, MCM-41 and ZSM-5) were synthesized. Coupling of SBA-16 with 3-Aminopropyl-triethoxysilane (APTES) was performed to improve surface characteristics of SBA-16. Different methods to load carvedilol on these carriers were used with high-performance liquid chromatography (HPLC) as a method of analysis for carvedilol. For the characterization of the loaded NPs Fourier-transform infrared spectroscopy (FT-IR), X-ray crystallography (XRD) and Therapeutic goods administration (TGA) were used. MCM-41 loaded with Carvedilol was decided to be formulated as tablet dosage and compared with tablets contain carvedilol without carrier. The results showed that SBA-16, SBA-16 coupled, ZSM-5 and MCM-41 carriers were used successfully to load carvedilol in a good drug load percent of 64.5, 69.3, 82 and 90%, respectively. MCM-41 gave highest loading efficiency of carvedilol using solvent evaporation method and the dissolution of carvedilol from powder was superior to the pure carvedilol where it gave 100% release of the drug at 15 minutes compared to 30% of pure carvedilol. MCM-41 loaded with carvedilol was successfully formulated as tablet dosage form according to the specifications of USP and the release of carvedilol from the prepared tablet was 99% at 15 min compared to the carvedilol released from tablets prepared using carvedilol powder which gave 38% which indicates the efficiency of the carrier in increasing the solubility and dissolution of carvedilol, a class II BCS drugs.

The chromatographic separation was achieved using a column type Zorbax-x Sβ-C18 (4.6 × 250 mm, 5 μm particle size). Mobile phase consisted of 0.05 M H 3 PO 4 , acetonitrile, and methanol in the 45:45:10 (v/v) ratio. The method was validated as per ICH guidelines in terms of system suitability, ranges, linearity, precision, specificity, accuracy, robustness, limit of quantification (LOQ) and limit of detection (LOD). The retention time (RT, t r ) for MTFN and CGLN were obtained at 8 and 9.45 min, respectively. The calibration curves were found linear in the range of 5 – 100 μg/mL for both drugs in this study, with good correlation coefficients ( R 2 > 0.99898). The suggested design proved to be selective and stability-indicating by the resolution ( R s ) of both analytes as well as by the study of forced-degradation (hydrolysis, oxidation, photolysis, and dry heat) products. The validated HPLC-DAD procedure was profitably tested for the analysis of CGLN and MTFN in their combination pharmaceutical tablet dosage form. In conclusion, a simple selective HPLC-DAD method has been successfully developed and validated for the determination of CGLN and MTFN simultaneously in pharmaceutical dosage form.
