Physicochemical and Microbiological Stability of Ursodiol Oral Compounded Suspensions.

Objective: In the United States, ursodiol is commercially available as solid dosage forms, which represents a problem for children who cannot swallow capsules or tablets. There is a lack of an age-appropriate formulation for ursodiol, and the extemporaneous preparation of an oral suspension with an extended beyond-use-date (BUD) may represent a good therapeutic alternative for the pediatric population. However, all pharmacists need validated stability studies to prepare oral liquids with high quality and safety.

Physicochemical and Microbiological Stability of Compounded Bethanechol Chloride Oral Suspensions in PCCA Base, SuspendIt®.

Bethanechol chloride is a cholinergic agent used to treat acute postoperative and postpartum nonobstructive (functional) urinary retention and for neurogenic atony of the urinary bladder with retention. It is available in the United States as tablets for oral administration in four dosage strengths: 5 mg, 10 mg, 25 mg, and 50 mg. A review of the therapeutic uses of bethanechol chloride reveals the need for flexibility in dosing.

In vitro evaluation of the percutaneous absorption of progesterone in anhydrous permeation-enhancing base using the Franz skin finite dose model and mass spectrometry.

Progesterone is used for hormone replacement therapy through various routes of administration. This study was conducted to (a) evaluate the stability of progesterone in a proprietary anhydrous permeation-enhancing base (APEB) and the efficiency of its skin permeation, and (b) determine the appropriateness of mass spectrometry as a method of analysis for permeated progesterone. Using a proven stability-indicating ultra-performance liquid chromatographic method, the compounded hormone (100 mg progesterone/g APEB gel) was determined to be physically and chemically stable at room temperature for six months.

Testosterone Therapy for Late-Onset Hypogonadism: A Clinical, Biological, and Analytical Approach Using Compounded Testosterone 0.5-20% Topical Gels.

Testosterone is integral to men's sexual and overall health, but there is a gradual decline in the ageing male. The topical administration of testosterone is a valuable option as a supplement (replacement) therapy to alleviate hypogonadal symptoms. The clinical efficacy of a compounded testosterone 5% topical gel was assessed retrospectively in a male patient in his seventies by evaluating the laboratory testing of the serum total testosterone and the results of a validated androgen deficiency questionnaire.

Evaluation of the in vitro human skin percutaneous absorption of ketoprofen in topical anhydrous and aqueous gels.

Background: Ketoprofen is a nonsteroidal anti-inflammatory drug used for the treatment of acute and chronic pain associated with inflammatory conditions. This study aims to evaluate the in vitro percutaneous absorption of ketoprofen 10% formulated in proprietary anhydrous and aqueous gels using the Franz skin finite dose model.

Materials And Methods: The anhydrous gel was initially characterized for cytotoxicity using EpiDerm skin tissue model by cell proliferation assay and Western blot analysis.

Analysis of the Physical Characteristics of an Anhydrous Vehicle for Compounded Pediatric Oral Liquids.

The paucity of suitable drug formulations for pediatric patients generates a need for customized, compounded medications. This research study was set out to comprehensively analyze the physical properties of the new, proprietary anhydrous oral vehicle SuspendIt Anhydrous, which was designed for compounding pediatric oral liquids. A wide range of tests was used, including sedimentation volume, viscosity, droplet size after dispersion in simulated gastric fluid, microscopic examination and content uniformity measurements to evaluate the properties of the anhydrous vehicle.

Evaluation of an Anhydrous Permeation-Enhancing Vehicle for Percutaneous Absorption of Hormones.

The efficiency and safety of hormone delivery through the skin partly depend on the appropriate choice of vehicle and the type of formulation. The present study reports the skin cytotoxicity, irritancy, and safety of a newly developed anhydrous permeation-enhancing base (APEB) and the percutaneous absorption of progesterone, testosterone, estriol, and estradiol in APEB formulations. Using the human skin EpiDerm model, cell death was not observed after 4 h of exposure to APEB and was 48% after 24 h, indicating its mild to non-irritating property.

Beyond-use Date of Trimix: A Reproducible Stability Study Using Bracketing Design.

Trimix is a widely prescribed penile injection for patients with erectile dysfunction and is only available as a compounded medication. The instability of alprostadil, one of the major ingredients of Trimix, has been a limiting factor in its utilization. There are published stability data for Trimix formulations that have been used to establish a beyond-use-date.

In vitro evaluation of Naltrexone HCl 1% Topical Cream in XemaTop™ for psoriasis.

Psoriasis is a multifactorial skin disease involving abnormal cell proliferation and inflammation; an efficacious topical treatment is yet to be identified. A formulation containing 1% Naltrexone HCl in XemaTop™ base was compounded, characterized and evaluated in vitro as a possible treatment for psoriasis. A three-dimensional psoriasis tissue model was exposed to the formulation for 2 or 5 days and analyzed for the level of markers of cellular proliferation, and inflammatory cytokine IL-6.

Physicochemical Stability of Extemporaneously Prepared Methylcobalamin Injections in the Presence and Absence of Preservative and the Impact of Light Exposure.

Methylcobalamin, one of the two active forms of vitamin B12, is the most effective analog in permeation and in transportation of neurons in subcellular organelles. Formulations of methylcobalamin are only commercially available in a few countries, which make them inaccessible for most patients. Extemporaneously prepared injections become the only option for those patients.

Physical and Chemical Stability of Estriol 0.025% to 1% Vaginal Creams (VersaBase).

Estrogen replacement therapy is often recommended when female patients present with lower than normal physiologic levels, such as patients going through menopause. The physical and chemical stability of estriol 0.25 mg/g and 10 mg/g vaginal creams (VersaBase) was tested over a period of 182 days, at room temperature and refrigerated conditions, in order to determine the corresponding beyond-use date.

Physical and Chemical Stability of Budesonide Mucoadhesive Oral Suspensions (MucoLox).

Budesonide is a corticosteroid that has been shown effective in the treatment of eosinophilic esophagitis, but there are currently no commercial medicines to treat this chronic allergic/immune condition, despite its prevalence in the U.S. Therefore, pharmaceutical compounding is the alternative choice to meet the therapeutic need of eosinophilic esophagitis patients.
