The objective of this study was to investigate the stability of compounded nifedipine cream in gel and ointment formulations dispensed in white plastic and glass amber jars. Extemporaneously compounded nifedipine cream (Glaxal Base), gel (K-Y Jelly), and ointment (Aquaphor) in white plastic and glass amber jars were stored at 4°C, 23°C, and 40°C. We determined potency on days 0, 7, 14, 30, 60, and 90, and subsequently assigned beyond-use-dates based on United States Pharmacopeia recommendations, organoleptic properties, and pH changes. Nifedipine potency in cream and ointment stored in white plastic jars was within ±10% of initial for 90 days (excluding day 14 for cream). In glass amber jars, potency was outside the acceptable range by day 14 at 23°C but within range for 90 days at 4°C (excluding day 30). Nifedipine potency was maintained for 90 days in both jars at 23°C and 4°C (excluding day 30) and in white plastic jars at 40°C, but 60 days stored in glass amber jars. The pH of formulations was stable with changes of less than 1-unit pH. At 40°C, a significant decrease in apparent viscosity of cream was evident on day 90. There was a decrease in apparent viscosity and phase separation of the ointment at 40°C and an increase in apparent viscosity (difficult to mix) at 4°C on day 14 onwards. Significant organoleptic changes were observed by day 7 at 40°C (decrease in apparent viscosity and abnormal odor by day 90), day 30 at 4°C (thicker consistency), and day 90 at 23°C (abnormal odor). Storage in white plastic jars at 23°C is recommended for compounded topical nifedipine cream and ointment (for 90 days), and for gel (60 days).

Review
Ointments are highly viscous forms intended for external applications either medicated or non-medicated means. Formulation of ointment depends upon the base ingredients to measure the viscosity difference. Several limitations of ointment bases has been encountered timely as agglomeration, oil phase ingredients can form lumps, poor dispersion, poor drug delivery efficiency, make stained, immiscible, and difficult to wash off. Therefore, it is necessary to make a new type of ointment bases that can overcome those limitations. This review summarizes a new type of ointment base preparation from the copolymer of renewable phenolic derivatives. The nanohydrogel preparation from these copolymers are especially effortless and highly efficient in drug delivery, exhibited versatile biological activities such as antioxidant, anti-inflammatory and wound healing in addition to antimicrobial property. Molecular self-assembly mechanisms have been addressed for nanogel formulation. The strategy makes a significant value in health-care application and be supposed to come marketed soon.

Wound-healing deficits of the skin, one of the most common complications in patients with diabetes, delay wound healing, significantly reducing the patient's QOL. Therefore, the topical treatment of wound areas with drug-containing ointments and dressings is important. In this study, we investigated the effect of various ointment bases on skin wound healing in normal and streptozotocin-induced diabetic rats (STZ rats). Three ointment bases were used: white ointment (oil-based), absorbent cream (emulsion-based, w/o), and macrogol ointment (water-based). Skin wound healing in STZ rats was delayed compared with that in normal rats. Each of the three ointment bases was applied to the skin wound area in normal rats, and there was no difference in the therapeutic effect. The therapeutic effect of both white ointment and absorbent cream was higher in the STZ rats group than that in the non-treated group, and delayed wound healing was observed in STZ rats treated with macrogol ointment. In conclusion, skin wound healing in STZ rats is affected by the properties of the ointment base, and it is important to use an ointment base that controls the drying of the wound area in STZ rats. These findings provide information for the selection of ointment bases useful for application to skin wounds in patients with diabetes.

The phytochemical analysis of the investigated Immortelle essential oil revealed the presence of monoterpenes and sesquiterpenes as major components that might be efficient as a wound healing potential agent. The present study aimed to develop an ointment based on the Immortelle essential oil and investigate its wound healing effects on excision wounds in diabetic rats. The topical formulated Immortelle ointment was subjected to pharmaco-technical characterization. Thirty-two diabetic rats with the induced excision wound were used to evaluate in vivo wound healing effects of ointment. The animals were randomly divided into four groups untreated or topically treated with either a 1% silver sulfadiazine, the ointment base, or Immortelle ointment. The response to the treatment was assessed by macroscopic, biochemical and histopathological analysis. The ointment, compatible with the skin remained stable for 6 months. Topical application of the Immortelle ointment showed the highest wound contraction with the highest content of hydroxyproline in comparison to the all examined groups. The Immortelle ointment showed significant wound contraction from day 7 to day 21 as compared to other groups. On the day 21, there was an average of 99.32% wound contraction in the Immortelle group, whereas the mean wound contraction in the negative control and ointment base group was 71.36% and 81.26% respectively. The histopathological results validated the potential wound healing effect of Immortelle ointment with evident post-excision scar maturation and increased collagen fibers density. Our findings revealed that the Immortelle ointment approach might serve as a promising and innovative tool for wound healing.

American Journal of Pharmaceutical... Feb 2014OBJECTIVES. To improve students' skills in selecting appropriate ointment bases through the development and implementation of a flowchart.
UNLABELLED
OBJECTIVES. To improve students' skills in selecting appropriate ointment bases through the development and implementation of a flowchart.
DESIGN
A flowchart was designed to help students select the appropriate base for an ointment. Students used the flowchart throughout the semester in both dry and wet laboratory activities. At the end of the semester, students completed a dry laboratory practical that required them to select an appropriate ointment base and levigating agent.
ASSESSMENT
Student performance data from the year prior to implementation was compared to data for 2 years after implementation. Calculation, procedure, and labeling errors also were compared. Prior to implementation of the flowchart, 51 of 101 students selected the correct base. After implementation, 169 of 212 students selected the correct base (p<0.001). Calculation, procedure, and labeling errors were not significantly different. CONCLUSION. Use of a flowchart to select an ointment base improved student performance when used in the context of a dry laboratory assignment.
