Preclinical research and development of a herbal antipyretic drug based on leaves of Ceiba pentandra (Malvaceae)

Background: Faced with the limits of synthetic antipyretic substances, in particular their involvement in the occurrence of numerous and often serious adverse effects; the challenge is in search of new antipyretics especially from the African traditional pharmacopoeia. The objective of this study was to evaluate the antipyretic activity of an aqueous extract and a formulation of Ceiba pentandra, with a view to designing an herbal antipyretic drug.

Methods: Trials of formulation of an antipyretic syrup with leaves extract of Ceiba pentandra were carried out. The antipyretic activity was investigated by the bewer's yeast induced pyrexia. Physicochemical and microbiological stability tests were carried out on the syrup.

Results: It was found with the extract an antipyretic activity at doses of 125 mg/kg and 150 mg/kg. The effect was greater for the 125 mg/kg dose with inhibition percentages ranging from 27.58% to 71.25%. This antipyretic activity was early (from 30 minutes) and was preserved during the four hours of the experiment. The syrup dosed at 125 mg/kg gave an activity similar to that of the extract by significantly reducing the hyperthermia in the rats. Regarding the stability tests, the syrup remained stable both physico-chemically and microbiologically throughout the study period (28 days) both when exposed to low temperature (5 °±3 ° C) and at high temperature (40°±2° C).

Conclusions: Ceiba pentandra leaves have antipyretic activity and could be used for the development of an herbal antipyretic drug.

Electrolyte disorders in a young female following short-term omeprazole therapy

A 29 years old female presented to us in the metabolic clinic of the University of Port Harcourt Teaching Hospital (UPTH) on account of a week history of easy fatigability, weakness, and lower extremity muscle cramps associated with numbness and tingling sensation in the peri-oral area, fingers and toes. Two weeks prior to the onset of her presenting symptoms, she had visited a local pharmaceutical shop on account of a distressing epigastric discomfort and was subsequently placed on daily oral omeprazole 20mg daily for a month by a pharmacist. She had been on the omeprazole medication for two weeks before her present symptoms manifested. Her past medical history was not suggestive of hypoparathyroidism nor pancreatitis. She was married with three children and has an uneventful family, social and obstetric histories. On examination, she was a healthy well-oriented young female with positive Trousseau’s, Chvostek’s and epigastric tenderness signs. Further Laboratory evaluation revealed she had low plasma magnesium, low plasma albumin-corrected calcium, and low serum parathyroid hormone levels, while other laboratory parameters were essentially normal. A diagnosis of omeprazole-induced electrolyte disorders (hypomagnesaemia and hypocalcaemia) associated with hypoparathyroidism was made following the review of her clinical examination and laboratory findings. She was subsequently managed with oral magnesium supplements following the withdrawal of the omeprazole medication (replaced with oral ranitidine), monitored weekly, and full recovery was achieved after three weeks.
