Cosamid Plus

Cosamid Plus Uses, Dosage, Side Effects, Food Interaction and all others data.

Glucosamine is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Glucosamine stimulates the production of proteoglycans and increases sulfate uptake by articular cartilage.

The administration of glucosamine, in theory, provides a building block towards the synthesis of glycosaminoglycans, slowing the progression of osteoarthritis and relieving symptoms of joint pain. Studies to this date examining the efficacy of glucosamine sulfate have been inconclusive. Glycosaminoglycans contribute to joint cartilage elasticity, strength, and flexibility. A systematic review of various studies and guidelines determined that modest improvements were reported for joint pain and function in patients taking glucosamine. A consistent joint space narrowing was observed, but with an unclear clinical significance.

Uses

Indicated for the treatment of osteoarthritis of knee, hip, spine, and other locations. Also used as dietary supplement

Cosamid Plus is also used to associated treatment for these conditions: Arthritis, Backache, Joint Pain, Osteoarthritis (OA), Osteoarthritis of the Knee

How Cosamid Plus works

The mechanism of action of glucosamine in joint health is unclear, however there are several possible mechanisms that contribute to its therapeutic effects. Because glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, glucosamine supplements may help to rebuild cartilage and treat the symptoms of arthritis. Some in vitro studies show evidence that glucosamine reduces inflammation via inhibition of interferon gamma and Nuclear factor kappa B subunit 65 (NF-κB p65), improving the symptoms of arthritis and joint pain. Clinical relevance is unknown at this time.

Dosage

Cosamid Plus dosage

500 mg tablet three times daily or as directed by the physician. A single dose of 1500 mg daily may also be effective. Obese individuals may need higher doses, based on body weight.

Side Effects

Safety studies with Glucosamine show no demonstrable toxicity. Rarely occurring side effects like mild & reversible intestinal flatulence are almost like placebo.

Toxicity

The oral LD50 of glucosamine in rats is >5000 mg/kg. Symptoms of an overdose with glucosamine may include nausea, vomiting, abdominal pain, and diarrhea (common side effects of this drug). Severe and life-threatening hypersensitivity reactions to glucosamine may occur in patients with a shellfish allergy or asthma.

Precaution

Diabetics are advised to monitor blood glucose levels regularly while taking Glucosamine. No special studies were formed in patients with renal and/or hepatic insufficiency. The toxicological and pharmacokinetic profile of the product does not indicate limitations for these patients. However, administration to these patients with severe hepatic or renal insufficiency should be under appropriate medical supervision.

Interaction

There have been no reports of significant drug interactions ofGlucosamine with antibiotics, antidepressants, antihypertensives, nitrates, antiarrhythmics, anxiolytic, hypoglycaemic agents, anti-secretives.

Volume of Distribution

Results of a pharmacokinetic study of 12 healthy volunteers receiving three daily consecutive oral administrations of glucosamine sulfate soluble powder demonstrated glucosamine distribution to extravascular compartments. Human pharmacokinetic data for glucosamine is limited in the literature, however, a large animal model study of horses revealed a mean apparent volume of distribution of 15.4 L/kg. Concentrations of glucosamine ranged from 9-15 microM after an intravenous dose, and 0.3-0.7 microM after nasogastric dosing. These concentrations remained in the range of 0.1-0.7 microM in the majority of horses 12 hours after dosing, suggesting effectiveness of a once-daily dose. In rats and dogs, radioactivity from a C-14 labeled dose of glucosamine is detected in the liver, kidneys, articular cartilage, and other areas.

Elimination Route

In a pharmacokinetic study, glucosamine was 88.7% absorption by the gastrointestinal tract. Absolute oral bioavailability was 44%, likely due to the hepatic first-pass effect. In a pharmacokinetic study of 12 healthy adults receiving oral crystalline glucosamine, plasma levels increased up to 30 times the baseline levels and Cmax was 10 microM with a 1,500 mg once-daily dose. Tmax was about 3 hours. AUC was 20,216 ± 5021 after a 15,000 mg dose.

Half Life

The estimated half-life for glucosamine is 15 hours after an oral dose. After a bolus intravenous injection of 1005 mg crystalline glucosamine sulfate, the parent drug has an apparent half life of 1.11 hours.

Elimination Route

Fecal excretion of glucosamine in a pharmacokinetic study was 11.3% within 120 hours after administration. Urinary elimination was found to be 1.19% within the first 8 hours post-administration.

Pregnancy & Breastfeeding use

Women who are pregnant or who could become pregnant should not supplement with glucosamine. Glucosamine has not been studied enough to determine their effects on a developing fetus. And no studies have evaluated the use of Glucosamine during pregnancy or lactation. It should be taken with caution and medical advice during pregnancy and lactation.
