Paediatric oral formulations: comparison of two extemporaneously compounded suspensions from tacrolimus capsules

Study objectives: The objective of this study was to determine the stability of tacrolimus in extemporaneously compounded liquid formulations. Methods: Two sets of liquid formulations were prepared using two different vehicles: one set in sterile water and in simple syrup (1:1) and one set using equal volumes of commercially available suspending agent (Ora-Plus) and simple syrup. The concentration of tacrolimus in each formulation was 0.5 mg/mL. The preparations containing Ora-Plus were stored at 25°C, the formulations that were prepared with sterile water and simple syrup were stored under refrigeration at 4°C. Results: Samples were collected at regular time intervals over a period of 56 d…

Assessment of Organochlorine Pesticide Residues in West African City Farms: Banjul and Dakar Case Study

Validated analytical procedures for the determination of 21 organochlorine pesticides have been applied to 74 water samples, 76 soil samples, and 160 vegetable samples from nine Sene-Gambian farms. Mean pesticide residue levels found were compared to the results of other studies. The main contaminants were DDTs in water (231.9 ng/L), in soil (71.4 ng/g), and in vegetables (5.03 ng/g). The distribution of pesticide residues in water and neighboring soils and the soil-plant transfer of these pesticides is briefly discussed. Different bioconcentration factors for sum HCHs, sum DDTs, and sum endosulfans obtained in this study allow us to confirm the complex processes already reported in the lit…
