This study describes a new method for the preparation of extemporaneous paracetamol-based suspensions for pediatric and adult patients. This method allows the preparation of extemporaneous suspensions up to concentrations of 50 mg/mL by using a liquid base, named "Puccini". A high-pressure liquid chromatographic method was developed and validated for the determination of chemical stability of paracetamol when the formulations were stored at 4°C and 25°C. The chemical stability of the active pharmaceutical ingredient in the base was demonstrated for more than 90 days. Visual analyses of the formulations showed a phenomenon of precipitation at both storage temperatures, but the simple agitation of the formulations before its use re-established the formation of homogeneous suspensions.

The great majority of sterile products commercially available as well as prepared in compounding pharmacies are sterilized by sterile filtration during aseptic processing. This brief and basic review will highlight the nature, action, and use of sterilizing filters. Special emphasis is given to how filters are validated in producing a sterile filtrate while being compatible with the filtered solution, as well as how filters are integrity tested during aseptic processing.

Background: Alopecia is a chronic dermatological disorder affecting men and women worldwide. Given the high incidence and significant impact on patients' well-being, options for managing and treating alopecia are essential. Topical available options remain limited and oral products may result in adverse effects. TrichoFoam™ is a ready-to-use foaming vehicle developed for compounding pharmacies and formulated with gentle, non-irritating, and sensory-pleasant ingredients.

Objective: The purpose of this study was to assess topical foams' physicochemical and microbiological stabilities of formulations compounded with TrichoFoam™ as the ready-touse vehicle.

Methods: HPLC analyses were conducted in a bracketed study covering concentrations of 0.1% to 2.0% of caffeine, 0.01% to 0.1% of clobetasol propionate, 0.1% to 0.25% of dutasteride, 0.25% to 0.50% of nicotinamide, and 0.25% to 2.5% of progesterone compounded with TrichoFoam™. Antimicrobial Effectiveness Testing was conducted at the beginning and end of the studies.

Results: Most formulations presented a beyond-use date of at least 90-180 days, except for clobetasol propionate, which showed compatibility for 14 days, and dutasteride 0.25%, which showed a BUD of 30 days.

Conclusion: This validates the stability of the active pharmaceutical ingredients from different pharmacological classes with TrichoFoam™, suggesting that this ready-to-use vehicle can be an excellent alternative for personalized alopecia treatment.

Pharmaceutical compounding has a crucial role for the health of patients, allowing the preparation of formulation out of market or for a personalized therapy. This study is aimed to conduct a screening of possible ready-to-use hydrophilic vehicles for the preparation of topical dosage forms. Incorporation tests of several active pharmaceutical ingredients were performed, and the physical stability of the extemporaneous formulations was assessed by performing an accelerated centrifuge test. The results showed that it was possible to realize several physically stable topical medications without using special equipment or instruments, guaranteeing a fast and repeatable preparation process. The goal of this work is to provide compounding pharmacists a table that summarizes some of the possible vehicles that can be used for the formulation of topical treatments.

The need for continued improvement in pain management is growing. This review is aimed towards identifying the literature regarding clinical and therapeutic value of the commonly used ingredients in pain management compounds: lidocaine, tetracaine, ketoprofen, ketamine, and gabapentin. Prospectively, future studies should be conducted to identify the exact benefits and side effects of compounded pain management therapies, such that these compounds can be effectively utilized when deemed appropriate.

Male hypogonadism is a common condition widely associated with the aging process. Understanding of this condition is continuing to grow as new information is available. Pharmacists are in a very unique position to work with patients and physicians in achieving better diagnosis and treatment plans for the hundreds of thousands of men in the U.S. who are hypogonadal. This article discusses various methods that can be employed to restore testosterone in men and the varying expectations associated with each treatment method.

The release of United States Pharmacopeia Chapter <800> and the revisions to United States Pharmacopeia Chapter <795> (official November 1, 2023) indicates a changing regulatory climate and a trend towards increasingly high standards for the extension of beyond-use dates beyond the default recommended by the guidelines. Given the increased scrutiny and the additional requirements for establishing extended beyond-use dates, additional testing is required to help pharmacies provide the best formulations with scientifically robust data to support an extended beyond-use date for patient convenience. The objective of this study was to demonstrate the suitability of two vehicles, Phytobase and HRT Heavy, for compounded hormone therapy by evaluating the stability and antimicrobial effectiveness of the vehicles with common combinations of hormones.

Minoxidil is one of the most employed active pharmaceutical ingredients for the  treatment of androgenetic alopecia. The authors propose a new method for production of minoxidil lotions using Aloplus Total. The latter is a propylene glycol-free liquid base in which the presence of hydroxypropyl-ß-cyclodextrin and ethanol allows the solubilization of high drug amounts. Minoxidil intrinsic solubility in the base was determined, and a comprehensive chemical and physical stability study was conducted on 8% w/w minoxidil lotions. Incorporation tests of different active pharmaceutical ingredients that can be combined to 5% w/w minoxidil were also carried out. The analyses showed that minoxidil intrinsic solubility in the new base was 85.93 mg/mL ± 4.17 mg/mL (8.64% w/w ± 0.42% w/w) at 25°C, and the topical lotions were found to be physically and chemically stable for more than 180 days when stored at 25°C or 40°C. Incorporation tests of several active pharmaceutical ingredients also were successful, indicating that Aloplus Total is a liquid vehicle also useful for the preparation of minoxidil-based topical lotions for a synergistic treatment of androgenetic alopecia.

Compounders worldwide are responsible for ensuring that the sterile preparations they dispense are pure, potent, and safe. To achieve that result, proper cleaning and disinfection of International Organization for Standardization controlled environments must occur. Because those tasks must be performed according to established standards, the compounding pharmacist must research regulatory requirements and appropriate products for use. In this report, we focus on U.S. regulations, guiding entities, and effective products that enable compliance with the increasingly stringent procedures required for pharmaceutical compounding. We also review cleaning and disinfecting processes, discuss the importance of correctly choosing and using disinfectants and/ or sporicidal disinfectants with surface claims in the cleanroom, and provide answers to questions frequently asked by staff who use those agents. In addition, we profile specific disinfectants that are compliant with United States Pharmacopeia Chapter <797> and current good manufacturing practice standards. Biological safety cabinets and compounding aseptic containment isolators must undergo an additional process that deactivates hazardous drug residues and removes them from the interior surfaces of those devices before they are cleaned and disinfected, but that discussion is beyond the scope of this article.
