The aims of this survey were to determine how veterinary ophthalmologists worldwide use compounded ophthalmic drugs to treat ocular diseases, define their attitudes regarding compounding pharmacies, and identify commonly dispensed veterinary ophthalmic formulations as well as the diseases for which those preparations are most often prescribed. Respondents voluntar i ly and anonymously completed a questionnaire that was sent to a total of 1014 veterinary ophthalmologists at universities, specialty colleges, and ophthalmology associations in 24 countries. One hundred thirty (12.83%) veterinary ophthalmologists replied. Of those, 87 (66.92%) had worked in  veterinary ophthalmology for more than 10 years. Ten to 30% of their total prescriptions were compounded ophthalmic drugs, the most common of which were tacrolimus and cyclosporine for the treatment of keratoconjunctivitis sicca. Reported advantages of treatment with a compound included the accessibility of preparations that were not commercially available and the ability to customize formulations; reported disadvantages included brief shelf life, delivery time, and cost.

Ticagrelor is used to inhibit acute coronary syndrome, but its poor solubility and low bioavailability limit its in-vivo efficacy. The purpose of this study was to manufacture an optimized ticagrelor-loaded self-microemulsifying drug-delivery system in the form of tablets to enhance the solubility and dissolution of that drug. A preliminary study was conducted to determine the extent of turbidity of oils for this study, and a pseudoternaryphase diagram was used to identify the region of formation of microemulsion with 3 ratios (1:1,1:2, and 1:3). The solubility of ticagrelor was determined with the selected oil and a surfactant-and-cosurfactant mixture. A simplex lattice mixture design was used to compound the microemulsion. The microemulsion was converted to granules by the use of an adsorbent (aerosol) after a precipitation study. After characterization, the resultant granules were compressed into tablets for an in-vitro release study. The optimized formulation was subjected to various characterization procedures to determine the zeta potential, particle size, and surface morphology. The solubility of the drug was found to have increased manyfold in all formulations, and the optimized formulation was found to be 221.37 mg/mL. With respect to the ticagrelor tablets, aerosol up to 30% was needed as an adsorbent in the self-microemulsifying drug-delivery system. The compression of the ticagrelor granules was satisfactory for tablet formation. In all formulations, the release of the active drug was more than 80% within 30 minutes of dissolution time. The optimized icagrelorloaded self-microemulsifying drug-delivery system formulation consisted of medium-chain triglyceride oil (47.88.0%), surfactant (28.25%), and cosurfactant (23.85%), which significantly improved the dissolution of ticagrelor. The results of analysis via scanning electron microscopy revealed that the surface and size of the drug and the zeta potential were also satisfactory and suggested that the optimized ticagrelor-loaded self-microemulsifying drug-delivery system described in this report could be successfully used as an efficient method for achieving enhanced dissolution of ticagrelor.

These recommended tips can be set up as free-of-charge, attractive pamphlets, which can either be given to the veterinary patient's owner when medications are supplied or made available as a display.

Pyometra is a common disease in intact female canines characterized by an infection of the uterus. If it is not treated immediately, it could result in various complications such as fistulous tract development, sepsis, hemorrhage, uveitis, conjunctivitis, pyelonephritis, urinary tract infection, and myocarditis. In this case report, we highlight the benefits of the application of a topical ointment on wound healing after ovariohysterectomy in canine Pyometra. Following surgical intervention, the dog developed necrosis in her nipples and lost a portion of her mammary tissues. A large cyst formed and later ruptured, leaving the animal with a large wound. The vet applied a topical ointment, AlpaWash, to the affected area and prescribed antibiotic, analgesic, and antiinflammatory drugs to help manage the condition. The vet reported complete healing of the wounds within one month from the commencement of the treatment regimen.

Pain syndromes are among the most widespread, costly, and debilitating of all neurological disorders. The number of patients living with chronic pain is expected to increase with the aging population and with the rise in obesity and diabetes across the nation. This type of pain is often insensitive to the traditional pain pharmacopeia or surgical intervention. Over the last 10 years the number of prescriptions that have been compounded by pharmacists has increased dramatically. There are a number of drugs in the area of pain management that have been formulated and compounded by pharmacists to treat conditions such as diabetic neuropathy, fibromyalgia, postherpetic neuralgia, joint pain, arthritis, and a variety of other conditions. A significant portion of these compounded analgesic preparations is made up of topical/transdermal dosage forms such as gels and creams. While the efficacy and doses of these drugs in systemic dosage forms have been widely established, little is known about the permeation and efficacy of these compounds from topical/transdermal gels. This review will provide an overview of chronic pain as a disease, the mechanisms of chronic pain, current treatment approaches to chronic pain, and a discussion of the drugs that are typically compounded into these topical formulations and studied in clinical trials.

Alopecia is a chronic dermatological disorder that affects patients worldwide, with a significant impact on quality of life, self-esteem, and psychological wellbeing. However, commercially available options for alopecia treatment are still limited. Considering that topical formulations have a long-term use therapeutic profile, the safety of their ingredients should be closely evaluated to avoid potentially irritant substances. Alternative active ingredients with different mechanisms of action, as well as adequate vehicles, might increase patients' adherence leading to better clinical outcomes. The purpose of this study was to examine the irritation, skin sensitization, photoallergy, and phototoxicity potential of a line of ready-to-use vehicles for producing topical therapies for alopecia treatments, TrichoConcept™. Subjects were selected and randomly assigned to compare the patch test with the study products or to the control solution (sterile 0.9% NaCl solution). No clinical signs of irritation, sensitization, photoallergy or phototoxicity were reported. From the results of this study, it is suggested that the investigated products can be considered safe under the evaluated conditions, and the claims "dermatologically tested", "clinically tested", and "nonirritant" can be supported.

Diclofenac Sodium is a nonsteroidal anti-inflammatory drug (NSAID) that has analgesic, anti-inflammatory, and antipyretic properties, and has been found to be effective in treating a variety of acute and chronic pain and inflammatory conditions. A stability study was designed to assess the physical, chemical, and antimicrobial stability of three extemporaneously compounded bracketed Diclofenac Sodium formulations over time using a validated, stability indicating HPLC method. Diclofenac Sodium 1% and 15% were compounded in Medisca VersaPro™ Cream Base, VersaPro™ Gel Base and PLO Gel Mediflo™30 Compound Kit and stored at room temperature, in tightly closed, light resistant, plastic containers for 180 days. The organoleptic properties, pH, viscosity, and Diclofenac Sodium concentration of each formulation were evaluated at predetermined time points. Antimicrobial effectiveness testing of the compounded formulation according to USP <51> was also evaluated at the initial time point and after 180 days. The results demonstrated that all formulations remained within the specified stability criteria for the duration of the study. Therefore, an extended beyond-use-date of 180 days may be assigned to these compounded formulations under the studied conditions.

The preparation of formulations that are not currently on the market or prepared for customized therapy is possible by pharmaceutical compounding. In this study, incorporation tests of some active pharmaceutical ingredients in five ready-touse lipophilic semisolid vehicles were performed, and the physical stability of the prepared extemporaneous formulations was assessed by performing an accelerated centrifuge test. The results demonstrated that it was possible to formulate physically stable topical medications without using special equipment or instruments, ensuring a fast, efficient, and repeatable preparation process. The objective of this work was to provide to compounding pharmacists a table that summarizes some of the semisolid lipophilic vehicles, such as creams water/oil, and ointments, that can be used for the formulation of topical treatments.
