title: Comparative evaluation of some commercially available brands of pharmaceutical preparations for Na, K and Mg concentrations.
abstract: A study was carried out to investigate the concentrations of macro-elements (Na(+), K(+) and Mg(+2)) in twelve commercially available pharmaceutical preparations used as sex stimulant, by Atomic Absorption Spectrophotometer. A wet digestion method was adopted to prepare the samples. The results indicated that sodium concentration was maximum (3702 ± 29 μg g(-1)) in LB and minimum (495 ± 06 μg g(-1)) in H-E-H. Potassium concentration was maximum (6337 ± 13 μg g(-1)) in NBA while minimum (150 ± 06 μg g(-1)) in ZGRA. Magnesium concentration was maximum in V-100 (9226 ± 11 μg g(-1)) and minimum in FGRA (1194 ± 25 μg g(-1)). The concentration of macro-elements in the imported herbal preparations was in the order of Mg<Na<K and in the local herbal preparations as follows: Mg<K<Na. Some of these herbal preparations contain high level of macro-elements than the recommended daily dietary allowances. The excessive use of such preparations may cause severe allergic reactions, kidney damage and pulmonary atherosclerosis.
