Biomedical Effects and Toxicity

【Therapeutic Uses】
... Formerly used in treating complete heart block. ... The usual dose was 30 mg three or four times a day or about 1.7 mg/kg/day. Use of the drug was abandoned, largely because of its toxicity.
【Biomedical Effects and Toxicity】
Barium forms a protein adduct in serum and is deposited in bone up to 65%. ... Barium chloride is being taken up ... by oral ingestion up to 10-30%.
Nasal absorption of (133)barium chloride was estimated at 60-80% of the dose at 4 hr after dosing, and alveolar absorption may be of similar magnitude.
... In hamsters receiving (133)barium chloride by intragastric intubation, absorption was 11-32% of the dose ... .
A solution of (140)barium chloride was injected intramuscularly into five children and iv into two adults, all with normal skeletal metabolism. Three of the children and one adult also received (45)calcium chloride in the same injection. Following injection, the concn of barium in the serum fell rapidly for about 0.6 day and then more slowly; even so, the amt detected on day 6 was less than 0.0002% of the dose.
The absorption and distribution /were examined after/ a single oral dose (1, 5, 25, or 125 mg/kg) of (133)barium chloride in male weanling rats (weight and strain not specified). The animals were sacrificed at 0.5, 2, 4, 8, 16, and 24 hr after exposure, and tissue (133)barium concentrations were measured. ... The results indicated that (133)Ba is rapidly absorbed from the GI tract. Peak (133)Ba concentrations occurred 30 minutes post-administration in blood and soft tissues and two hr post-administration in the femur.
Five ml of a solution containing 3.7 mg (133)barium chloride (0.28 and 0.53 mg/kg) /were administered by gavage/ to two beagle dogs (13 and 7 kg, 2 and 4 yr of age, respectively). Mathematical treatment of total body retention and excretion data yielded an estimated GI absorption of 7% for barium.
The localization of (133)barium chloride in pigmented (CBA) and albino (NMRI) mice /were reported/. Males (25 to 30 g) and late gestation females (40 g) were sacrificed after intravenous injection of 63 ug barium/kg (0.063 mg barium/kg) containing (133)BaCl2. The calcified tissues, cartilage, kidney and melanin containing tissues of the male and female pigmented animals had the highest (133)barium activity at the earliest observation time (20 minutes after administration), but albino mice did not have correspondingly high activity in eyes or hair follicles. The calcified and cartilage tissues retained activity even at the longest survival time, 32 days. ... After four days the only sites other than bone, cartilage and melanin containing tissue having (133)Ba activity were the GI contents, urinary tract and salivary gland.
... The absorption of labelled barium chloride ... soln in 1-yr-old Syrian hamsters /via inhalation/. Absorption into the general circulation of soln deposited on nasal membranes was compared with GI tract absorption. During the first 4 hr after admin, barium absorption from the nasal passages was approx 61%, compared with 11% GI absorption. The authors concluded that the nasopharynx is a major absorption site for inhaled aerosols of soluble barium, esp for readily soluble aerosols having mass medium aerodynamic diameters >5 um.
Labelled barium chloride was admin by intragastric intubation to groups of 5 to 10 brown hooded female rats (14 days to 70 wk old). Absorption was estimated as the radioactivity 7 hr after exposure in the carcass plus urine minus GI tract in relation to the dose. The absorption decr with age, from approx 85% of the admin dose at 14-18 days of age, to 63% at 22 days, to approx 7% after 6-8 or 60-70 wk of age. Deprivation of food before admin (18 hr) markedly incr the absorption of barium, from approx 7% in fed animals to 20% in fasted animals 6-8 or 60-70 wk old. Admin of the cmpd in cow's milk did not affect absorption.
... Groups of 5 to 10 Syrian hamsters (1 yr old) were admin labelled barium chloride by intragastric intubation. The absorption estimate was based on carcass radioactivity 4 hr after exposure in relation to carcass radioactivity immediately after iv admin (100%). Results show that following a 12 hr fasting, a combination of gastric (32%) and intestinal (11%) absorption was found during the first 4 hr after admin.
... The absorption of specific barium salt anions /was examined/ in male Sprague-Dawley rats, admin radiolabelled barium chloride, sulfate, or carbonate to fasted (24 hr) and non-fasted rats by gastric intubation. animals were sacrificed from 2 to 480 min after admin and blood concn were measured. In general, barium blood concn were higher in fasted animals and reached a peak 15 min after dosing, whereas non-fasted animals had lower barium blood concn and peaked 60 min after dosing. The peak blood concn of the carbonate and sulfate salts were 45% and 85%, respectively, of that of the chloride.
Orally admin barium chloride ((133)BaCl2) was found to be rapidly absorbed from the GI tract of male weanling rats, the peak concn in the bloodstream and soft tissues occurring 30 min after dosing. Total uptake of barium incr with incr dosage, but, there appeared to be a saturation point for oral absorption ... .
... Injected labelled barium chloride ((133)BaCl2) iv in pigmented and albino mice (63 ug barium/kg body weight). Autoradiography revealed that uptake was rapid and retention times were longest in calcified tissues, cartilate, and melanin- containing tissues. In other tissues, the radioactivity rapidly disappeared. In the mouse fetus, the authors found that barium is mainly taken up by the skeleton, esp in the growth zones. Except for the eye, soft tissues had a low uptake.
... 24 Hr after an intragastric dose of labelled barium chloride to rats, the highest concn was in the heart, followed by the eye, kidney, liver, and blood.
... Labelled barium chloride ((133)BaCl2) admin orally to weanling male rats entered the bloodstream and soft tissues, peak concn occurring 30 min after admin. Uptake was observed in the submaxillary salivary gland, adrenal gland, kidney, gastric mucosa, and blood vessels. The deposition of barium in hard tissues was detected after 2 hr.
... Barium chloride (10, 50, or 250 mg barium/l of drinking water) /was administered/ to young adult rats of both sexes for 4, 8, or 13 wk. Barium deposition in liver, skeletal muscle, heart, and bone was dose-dependent but not related to the length of exposure. The highest concn of barium was observed in the bones. In soft tissues, concn were
... Whole body retention of barium in humans, 15 days after a single dose injection of labelled barium chloride ((133)BaCl2) was 10.5% of the initial dose.
... 34.8% of the initial dose was found in rats 16 days after a single dose injection of barium chloride.
In lactating cows, excretion in milk during the first 8 days after dosing was 0.6% of an oral dose and 10% of an iv administered dose ... .
