Almora
Almora Uses, Dosage, Side Effects, Food Interaction and all others data.
Almora is a magnesium salt of gluconate. It demonstrates the highest oral bioavailability of magnesium salts and is used as a mineral supplement. Magnesium is ubiquitous in the human body, and is naturally present in many foods, added to other food products, available as a dietary supplement and used as an ingredient in some medicines (such as antacids and laxatives) .
Although magnesium is available in the form of sulphates, lactate, hydroxide, oxide and chloride, only magnesium gluconate is recommended for magnesium supplementation as it appears to be better absorbed and causes less diarrha .
This drug has been studied in the prevention of pregnancy-induced hypertension, and has displayed promising results . In addition, it has been studied for its effects on premature uterine contractions .

Uses
Almora is a mineral supplement used to treat or prevent hypomagnesemia.
Almora is a mineral supplement which is used to prevent and treat low levels of magnesium. Magnesium is very important for the normal physiologic functioning of cells, nerves, muscles, bones, and the heart. Generally, a well-balanced diet provides the necessary amounts of magnesium for homeostasis. However, certain conditions causing chronic magnesium deficiency may decrease levels of magnesium. These conditions include treatment with diuretics, a poor diet, alcoholism, or other medical conditions (e.g., severe diarrhea/vomiting, stomach/intestinal absorption problems, poorly controlled diabetes) .
How Almora works
Replaces deficient circulating levels of magnesium .
By competing with calcium for membrane binding sites and by stimulating calcium sequestration by sarcoplasmic reticulum, magnesium helps in the maintenance of a low resting intracellular free calcium ion concentration, which is essential in various cellular functions. The electrical properties of membranes and their permeability characteristics are also affected by magnesium .
Magnesium is essential to many enzymatic reactions in the body, serving as a cofactor in protein synthesis and in carbohydrate metabolism .
Magnesium contributes to the structural development of bone and is also essential in the synthesis of DNA, RNA, and the antioxidant glutathione. Magnesium also plays an important role in the active transport of calcium and potassium ions across cell membranes, a process which is important to nerve impulse conduction, muscle contraction, and normal heart rhythm .
In addition to the above, magnesium is an essential mineral required for the regulation of body temperature, nucleic acid and protein synthesis, and in preserving nerve and muscle cell electrical potentials. Magnesium supplementation during pregnancy may help to reduce fetal growth restriction and pre-eclampsia, as well to increase birth weight .
Toxicity
Oral LD50 is 9100 mg/kg in the rat .
Excess magnesium from dietary sources does not pose a health risk in healthy individuals because the kidneys eliminate excess amounts of magnesium in the urine. On the other hand, high doses of magnesium from dietary supplements or medications often result in diarrhea that can be combined with nausea and abdominal cramping. Forms of magnesium most commonly reported to cause diarrhea include magnesium carbonate, chloride, gluconate, and oxide. Diarrheal and laxative effects of magnesium salts are due to the osmotic activity of unabsorbed salts in the intestine and colon and the stimulation of gastric motility .
Hypermagnesaemia after oral ingestion is uncommon except in patients with renal impairment. Signs and symptoms of hypermagnesemia may include respiratory depression, loss of deep tendon reflexes due to neuromuscular blockade, nausea, vomiting, flushing, hypotension, drowsiness, bradycardia and muscle weakness.
Very high doses of magnesium-containing laxatives and antacids (normally providing more than 5,000 mg/day magnesium) have been associated with the occurrence of magnesium toxicity, including fatal hypermagnesemia in a 28-month-old boy as well as an elderly man. Symptoms of magnesium toxicity, normally presenting at concentrations of 1.74–2.61 mmol/L, may include hypotension, nausea, vomiting, facial flushing, retention of urine, ileus, depression, and lethargy before progressing to muscle weakness, difficulty breathing, extreme hypotension, irregular heartbeat, and cardiac arrest. The risk of magnesium toxicity increases with compromised renal function or kidney failure because the ability to remove excess magnesium is reduced or lost .
Treatment: In patients with normal renal function, IV fluids or furosemide may be administered to promote the excretion of magnesium. In patients with symptomatic hypermagnesaemia, slow IV injection of calcium gluconate can be administered to antagonize the cardiac and neuromuscular effects of magnesium .
Food Interaction
No interactions found.Volume of Distribution
About 60% of the magnesium is present in bone, of which 30% is exchangeable and functions as a reservoir to stabilize the serum concentration. About 20% is found in skeletal muscle, 19% in other soft tissues and less than 1% in the extracellular fluid. Skeletal muscle and liver contain between 7–9 mmol/Kg wet tissue; between 20–30% of this is readily exchangeable. In healthy adults, the total serum magnesium is in the range of 0.70 and 1.10 mmol/L. Approximately 20% of this is protein bound, 65% is ionized and the rest is combined with various anions such as phosphate and citrate .
Elimination Route
A high-fat diet may decrease the amount of magnesium absorbed in the diet. Over-cooking food also may decrease the amount of magnesium absorbed from dietary sources .
About 1/3 of magnesium is absorbed from the small intestine. The fraction of magnesium absorbed is inversely proportional to amount ingested .
Oral absorption is estimated to be 15% to 30% .
Clearance
The kidney plays a major role in magnesium homeostasis and the maintenance of plasma magnesium concentration. Under normal circumstances, when 80% of the total plasma magnesium is ultrafiltrable, 84 mmol of magnesium is filtered daily and 95% of this amount it reabsorbed leaving about 3–5 mmol to be excreted in the urine .
Elimination Route
Oral: Via urine (absorbed fraction); feces (unabsorbed fraction) .
Phosphate depletion is associated with a significant increase in urinary magnesium excretion and may lead to hypomagnesemia. Hypercalcemia is associated with an increased urinary excretion of magnesium. The increase in magnesium excretion in hypercalcemia is greater than the increase in calcium excretion and is due to decreased reabsorption in the loop of Henle. Hypercalcaemia leads to a reduction in isotonic reabsorption in the proximal renal tubule causing greater delivery of sodium, water, calcium and magnesium to the loop of Henle. As a result of this increased flow to thick ascending loop of henle, calcium and magnesium transport may be inhibited. In addition, the high peritubular concentration of calcium directly inhibits the transport of both ions in this segment .
Osmotic diuretics such as mannitol and glucose cause a marked increase in magnesium excretion. Loop diuretics induce hypermagnesuria, and the increase in magnesium excretion is greater than that of sodium or calcium suggesting that loop diuretics may directly inhibit magnesium transport .
