Opis:
Metformin is used as an anti-diabetic drug among oral hypoglycemic drugs, which produces many gastrointestinal problems. Study aims to investigate the effect of metformin induced gastrointestinal problems and its prevalence. A cross-sectional study design was adapted using convenience sampling technique, at different Diabetic Centers of Lahore and Faisalabad, Pakistan from, June-2017 to November-2017. A total of 300 male and female patients participated in the study between 26 to 85 years and diagnosed with type-II diabetes. Data was directly collected from the patients and prevalence of metformin-induced gastrointestinal intolerance was determined by the symptoms of the patients. Data was analyzed by SPSS version 21. Results showed a significant difference between gender and symptoms (p=0.029). Moreover, the gastrointestinal problems were found to be dose related. A significant difference existed between patients who were taking 500mg and those taking 850 mg of metformin (p=0.006), patients who were taking 500mg and those taking 1000mg of metformin (p=0.000) and patients who were taking 850mg with those taking 1000mg of metformin (p=0.022). The prevelance of metformin-induced gastrointestinal symptoms was 45.8%. Most commonly occurring symptoms were, constipation (41.35%) followed by dyspepsia (27.89%), abdominal pain (26.92%), bloating and heart burn (25%), indigestion (15.38%), anorexia (11.54%), diarrhea (6.58%), flatulence (7.69%), nausea (6.73%) and vomiting (2.88%). It was concluded that gastrointestinal intolerance was more in females as compared to males. The gastrointestinal problems increased with the increase in dose. The side effects occurred were irrespective of the age and the most common gastrointestinal symptom was found to be constipation.

Opis:
Metformin HCl (Mtf) is a polar compound with low bioavailability. Counter ions have been shown to improve the bioavailability of polar ionizable drugs. The goal of this work was to develop an HPLC method that is capable of separating and quantifying Mtf from a group of selected organic anions: diclofenac sodium (DS), citric acid (CA), hydroxyl cinnamic acid (HCA), 8-anilinonaphthalene-1-sulfonic acid (ANS),and trisodium phosphate (TSP). Thus, the effect of the mixture of anions on the transport of Mtf through Caco-2 cells could be studied. During the development of the method, interesting chromatographic behaviors of Mtf were observed using a polar stationary phase (Hypersil® SAS, C1). The developed method was validated and found to be linear in the range 2-100 µg/mL with good accuracy and precision. The method was applied for transport experiments of Mtf across Caco-2 cells in the presence and absence of organic anions. Apparent permeability coefficients (Papp) were calculated. The Papp of Mtf was increased in the presence of CA and DS from 3.37×10-6 cm/s to 5.08×10-6 and 4.25×10-6 cm/s respectively, while it was decreased to 1.9×10-6 cm/s (p-value 0.01) in the presence of HCA. Interestingly, the Papp for Mtf increased more than four-fold when present with both calcium and CA together, which might lead to significant improvement in the bioavailability of the drug.
