  A preliminary evaluation was carried out on metronidazole-loaded Self Emulsifying Drug Delivery System (SEDDS) using two vegetable oils-Palm Kernel Oil (PKO) and Palm Oil (PO). Purification of oils, drug solubility in the oils, pre/post formulation isotropicity tests, emulsification times and release studies of metronidazole from the SEDDS were carried out. Results indicated solubility values of 4.441 and 4.654%w/w, respectively for metronidazole in PKO and PO. Preformulation isotropicity test revealed that out of the 24 batches evaluated 10 of the SEDDS formulations containing different oil: surfactant ratios and PKO:PO admixtures were found to be isotropic after 5 h. However when the SEDDS were loaded with metronidazole there was a reduction in the number (to 7) of formulations that maintained isotropicity and stability after 72 h. All the batches had emulsification times of less than two minutes except batch 4D with oil:surfactant concentration of 50:50. The release profile showed that most of the formulations released 50% of drug in less than 8 min and 85% of drug in less than 30 min. We therefore conclude that SEDDS containing the two vegetable oils are potential alternatives when immediate release and delivery of metronidazole is the primary motivation.

  The aim of this research was to formulate Zapoteca portoricensis root extract as Lozenges and to evaluate some of their antimicrobial and tablet properties. The root extracts were formulated into Lozenges using either Sodium Carboxy Methyl Cellulose (SCMC) or Carboxy Methyl Cellulose (CMC) as binders. Uniformity of weight, crushing strength, microbial sensitivity and pre-extinction time studies (using E. coli, S. aureus and Candida albicans) were conducted on three Lozenges formulated with either SCMC (Batch A), CMC (Batch B) and a reference standard, DequadinR, containing dequalinium hydrochloride (Batch C). Results showed that Batches B and C passed the weight uniformity test. The three batches had mean crushing strengths of 4.86±0.043, 3.9±0.03 and 13.1±0.43 KgF, respectively for A, B and C. S. aureus and Candida albicans were sensitive to the test lozenges whereas Escherichia coli was not. Candida albicans was minimally sensitive to the standard lozenge, while S. aureus was not. Both the test and the standard samples showed extinction times greater than 30 min.
