Abstract
Atorvastatin (ATV), a lipid-lowering agent, has low oral bioavailability due to its poor water solubility, permeability, and low dissolution rate. Therefore, pentaerythritol-EudragitRS100 co-processed excipients (PECE) were synthesized, and their feasibility as solid dispersion carriers (ATV-PECE-SD) for improving the solubility, permeability, and dissolution rate of ATV was explored. Solid dispersions were assessed in terms of particle size and zeta potential, and solubility, in vitro dissolution, and ex vivo permeation studies were studied. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), and powder X-ray diffraction (PXRD) were used as characterization tools. ATV-PECE-SD3 (1:4) formulations exhibited a small particle size with high stability. Physicochemical evaluation evidenced the formation of solid dispersion due to the involvement of weak electrostatic interaction between the polar functional groups of ATV and PECE carriers. ATV-PECE-SD3 (1:4) significantly enhanced the water solubility by ∼43-fold compared to pure ATV. In vitro dissolution studies showed that optimized formulation enhanced the dissolution rate of ATV compared to pure ATV. Ex vivo permeation results revealed that ATV-PECE-SD3 (1:4) enhanced the permeation rate of ATV compared to pure ATV. The optimized formulations significantly improved the dissolution rate of ATV in the fed state due to the food effect and micelle formation mechanism compared to the fasted state. The study concludes that co-processed excipients could be used as promising solid dispersion carriers to enhance the aqueous solubility, permeability, and dissolution rate of ATV.

Colloids Surf B Biointerfaces 2023; 227:113361. [PMID: 37236085 DOI: 10.1016/j.colsurfb.2023.113361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 04/08/2023] [Accepted: 05/16/2023] [Indexed: 05/28/2023]
Abstract
Despite significant advances in oral drug delivery technologies, many drugs are prone to limited oral bioavailability due to biological barriers that hinder drug absorption. Pro-nanolipospheres (PNL) are a form of delivery system that can potentiate the oral bioavailability of poorly water-soluble drugs through a variety of processes, including increased drug solubility and protecting them from degradation by intestinal or hepatic first-pass metabolism. In this study, pro-nanolipospheres were employed as a delivery vehicle for improving the oral bioavailability of the lipophilic statin, atorvastatin (ATR). Various ATR-loaded PNL formulations, composed of various pharmaceutical ingredients, were prepared by the pre-concentrate method and characterized by determining particle size, surface charge, and encapsulation efficiency. An optimized formula (ATR-PT PNL) showing the smallest particle size, highest zeta potential, and highest encapsulation efficiency was selected for further in vivo investigations. The in vivo pharmacodynamic experiments demonstrated that the optimized ATR-PT PNL formulation exerted a potent hypolipidemic effect in a Poloxamer® 407-induced hyper-lipidaemia rat model by restoring normal cholesterol and triglyceride serum levels along with alleviating serum levels of LDL while elevating serum HDL levels, compared to pure drug suspensions and marketed ATR (Lipitor®). Most importantly, oral administration of the optimized ATR-PT PNL formulation showed a dramatic increase in ATR oral bioavailability, as evinced by a 1.7- and 3.6-fold rise in systemic bioavailability when compared with oral commercial ATR suspensions (Lipitor®) and pure drug suspension, respectively. Collectively, pro-nanolipospheres might represent a promising delivery vehicle for enhancing the oral bioavailability of poorly water-soluble drugs.

Abstract
Background Hypolipidemic agents have been shown to be helpful in the primary and secondary prevention of cardiovascular disease. Most often, statins are prescribed to treat hyperlipidemia. There are a number of statins available in the market today, but atorvastatin is the most widely prescribed. It is essential that the drugs should have the appropriate amount of active pharmaceutical ingredient and meet the necessary physical properties. The main purpose of the study was to evaluate the quality of different marketed brands of atorvastatin calcium tablets available in Saudi Arabia. Methods In this study, innovator product coded as (AS-1) and five generics brands (coded as AS-2 to AS-6) of atorvastatin tablets 20 mg available in Saudi Arabia were evaluated for in vitro dissolution test, weight variations, friability and hardness tests. The analysis of drug was carried out by “high-performance liquid chromatography” (HPLC) method using C18 column (4.6 × 150 mm, 5 μm). The mobile phase was consisted of acetonitrile and HPLC water (pH 2.1, adjusted with orthophosphoric acid) in ratio of 52:48 v/v, the flow rate was 1.0 ml/min. Atorvastatin was detected at a wavelength of 254 nm. Results According to the results of the dissolution study, the investigated products released more than 90% of atorvastatin in 15 min. Within 60 min, the brands AS-1, AS-3, AS-5, and AS-6 depicted nearly 100% atorvastatin release, while the brand AS-2 displayed 91.69% drug release. According to our findings, the investigated atorvastatin innovator (AS-1) and generic brands such as AS-2 to AS-6 were of good pharmaceutical quality. Conclusions All generic brands of atorvastatin tablets available in the Saudi Arabian market met the pharmacopoeia's consistency checks such as weight variation, friability, hardness and in vitro dissolution. Hence, focusing on their in vitro release properties, it was determined that these brands could be used interchangeably.

Abstract
In this work, the photodegradation process of atorvastatin calcium (ATC) is reported as depending on: (1) the presence and the absence of excipients in the solid state; (2) the chemical interaction of ATC with phosphate buffer (PB) having pH equal to 7 and 8; and (3) hydrolysis reaction of ATC in the presence of aqueous solution of NaOH. The novelty of this work consists in the monitoring of the ATC photodegradation by photoluminescence (PL). The exposure of ATC in solid state to UV light induces the photo-oxygenation reactions in the presence of water vapors and oxygen from air. According to the X-ray photoelectron spectroscopic studies, we demonstrate that the photo-oxygenation reaction leads to photodegradation compounds having a high share of C=O bonds compared to ATC before exposure to UV light. Both in the presence of PB and NaOH, the photodegradation process of ATC is highlighted by a significant decrease in the intensity of the PL and photoluminescence excitation (PLE) spectra. According to PLE spectra, the exposure of ATC in the presence of NaOH to UV light leads to the appearance of a new band in the spectral range 340-370 nm, this belonging to the photodegradation products. Arguments concerning the chemical compounds, that resulted in this last case, are shown by Raman scattering and FTIR spectroscopy.

Abstract
Development of fixed dose combinations is growing and many of these drug combinations are being legally marketed. However, the development of these requires careful investigation of possible physicochemical changes during co-processing. This requires investigation of the effect of co-processing of drug combination in absence of excipients to maximize the chance of interaction (if any). Accordingly, the aim was to investigate the effect of co-processing of ezetimibe and atorvastatin on drugs dissolution rate. The objective was extended to in vitro in vivo correlation. Drugs were subjected to wet co-processing in presence of ethanol after being mixed at different ratios. The prepared formulations were characterized using FTIR spectroscopy, X-ray powder diffraction, differential scanning calorimetry, scanning electron microscopy, and in vitro dissolution testing. These investigations proved the possibility of eutectic system formation after drugs co-processing. This was reflected on drugs dissolution rate which was significantly enhanced at dose ratio and 2:1 atorvastatin:ezetimibe molar ratio compared to the corresponding pure drugs. In vivo antihyperlipidemic effects of the co-processed drugs were monitored in albino mice which were subjected to hyperlipidemia induction using poloxamer 407. The results showed significant enhancement in pharmacological activity as revealed from pronounced reduction in cholesterol level in mice administering the co-processed form of both drugs. Besides, histopathological examinations of the liver showed marked decrease in hepatic vacuolation. In conclusion, co-processing of atorvastatin with ezetimibe resulted in beneficial eutexia which hastened the dissolution rate and pharmacological effects of both drugs.Graphical abstract.

Abstract
In the present study, co-crystals (CCs) of Paliperidone (PPD) with coformers like benzoic acid (BA) and P-amino benzoic acid (PABA) were synthesized and characterized to improve the physicochemical properties and dissolution rate. CCs were prepared by the solvent evaporation (SE) technique and were compared with the products formed by neat grinding (NG) and liquid assisted grinding (LAG) in their enhancement of solubility. The formation of CCs was confirmed by the IR spectroscopy, powder X-ray diffraction and thermal analysis methods. The saturation solubility studies indicate that the aqueous solubility of PPD-BA and PPD-PABA CCs was significantly improved to 1.343±0.162mg/ml and 1.964±0.452mg/ml, respectively, in comparison with the PPD solubility of 0.473mg/ml. This increase in solubility is 2.83-and 3.09-fold, respectively. PPD exhibited a poor dissolution of 37.8% in 60min, while the dissolution of the CCs improved tremendously to 96.07% and 89.65% in 60min. CCs of PPD with BA and PABA present a novel approach to overcome the solubility challenges of poorly water-soluble drug PPD.

Abstract
Pharmaceutical cocrystals are a promising strategy to increase the solubility and dissolution rate of poorly soluble drugs. However, their manufacturing process requires a large quantity of solvents. The present study aimed to produce cocrystals by a solvent-free hot melt extrusion (HME) method to improve their solubility and dissolution rate. Aripiprazole (ARP) and adipic acid (ADP) were used as a weakly basic drug and acidic coformer, respectively. The processability of a plain ARP-ADP physical mixture (PM) compared with a PM with 5% Soluplus® (SOL) was investigated. Incorporating 5% SOL into the ARP-ADP blend reduced the processing torque and improved processability. The effects of temperature and screw speed on the formation of cocrystals were studied, and cocrystals were characterized by differential scanning calorimetry (DSC), fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, powder X-ray diffraction (PXRD), scanning electron microscopy, and hot-stage microscopy. FTIR spectra revealed noncovalent interaction between ARP and ADP, which was confirmed by NMR spectra. Similarly, PXRD data exhibited characteristic peaks confirming the formation of new crystalline material. Further, the results indicated that cocrystals demonstrated higher dissolution rates and improved compressibility, as well as enhanced flow characteristics compared with pure ARP, suggesting its suitability in the development of solid dosage forms.
