Don - instructions for use, reviews, indications and contraindications, side effects

General description

The preparation includes Glucosamine sulfate - chondroprotektornoe, anti-catabolic, analgesic and anti-inflammatory systemic substance, which is an amino-saccharide with a low mass of molecules.

The drug is manufactured by the Italian pharmaceutical company Rottafarm in the form of ampoules with a ready-made solution for intravenous administration, as well as a powder for internal oral administration.

The preparation quickly and effectively catalyzes the synthesis of proteoglycans, which in turn are considered the main "building material" for cartilage tissue. In addition, Dona slows the work of the enzyme phospholipase and collagenase, as well as oxide radicals with a lysosome, which in a complex destroy glucosaminoglycants and hyaluronic acid, the basis of cartilage.

In addition, glucosamine sulfate normalizes the accumulation processes in calcium tissues, protects chondrocytes from the harmful effects of corticosteroids, promotes retention of useful fluids, and also establishes enzymatic processes in the cellular structure of joints and cartilages with synovial membrane.

The drug is absorbed very quickly, concentrating mainly in articular cartilage. Output is an average of 70 hours, visible positive manifestations from admission are observed two weeks after the start of the course and persist for two months after refusing to use Dona.

Reviews of doctors

Victor Danitsin, traumatologist-orthopedist.

I prescribe Don to patients in acute post-operation period, most often at the first stage of treatment. The course - about a month, quite a lot of good patient testimonials and see a positive result.

Alexey Miller, out-patient traumatologist.

In general, the effect of all chondroprotectors is exaggerated, I judge by my own practice. Yes, they reduce pain syndromes, relieve periarticular inflammation, slightly increase the elasticity of the cartilage, which in turn increases the amplitude of limb movements, but there is no outstanding progress, in fact, the structure of the cartilaginous tissue is restored just as slowly. Therefore, Don is not de facto different from other protectors of this class.

Dmitry Dimchuk is an orthopedist practitioner.

Modern methodology has long ago discarded chondroprotectors as the main method of treatment of osteoarthrosis, osteochondrosis and so on. Don can be considered as an additional therapy for rehabilitation after surgery of transplantation of cartilaginous tissue from a nonworking surface to a working surface and after other surgical procedures.
