OBJECTIVE
The purpose of the present study is to explore the assessment if the transdermal delivery of vitamin D is feasible.
METHODS
In 50 female Medical students, this study was conducted. Age, weight and height was taken, a detailed history and clinical examination was performed. Blood was drawn for 25 Hydroxy Vitamin D3 (25OHD) level. Two women had >30 ng/mL of 25OHD and was excluded from the study. The participants were divided into two groups of 24 in each arm. All participants equivocally agreed not to change their dietary habits and life style till the study was over. The study group of women were asked to apply; Top-D (Aloe Vera based- Vitamin D3) (Patency Pending) was developed at King Fahd Hospital of the University, AlKhobar with each gram of the Top-D cream delivering 5000 IU of vitamin D3. The second group used 1 gram of Aloe vera gel. The participants had no knowledge to which group they belong. A second blood sample was taken at the end of 3 months and the data was analyzed.
RESULTS
The data of 48 women was available for analysis. The average age was 22.58 ± 1.95 years. The mean pre-treatment 25OHD in the study group was 12.05 ng/Ml ± 6.54 and post-treatment was 37.95 ng/mL ± 6.43 (P=0.001, CI<28.582 ). In control group pre-treatment 25OHD was 11.4 ng/mL ± 3.97 and post-treatment was 10.58ng/mL ± 3.03.
CONCLUSIONS
This randomized control study shows that vitamin D3 can safely be delivered through the dermal route. This route could be exploited in treating vitamin D deficiency.
