About the Product
COMPOSITION
1 ml of the solution contains:
chondroitin sulfate sodium — 100 mg.
INDICATIONS FOR USE
Degenerative diseases of the joints and spine, such as:
- primary osteoarthritis;
- osteoarthritis with predominant involvement of large joints;
- intervertebral osteochondrosis.
DOSAGE AND ADMINISTRATION
The drug is administered intramuscularly at a dose of 1 ml (100 mg chondroitin sulfate) every other day.
If well tolerated, the dose may be increased to 2 ml (200 mg chondroitin sulfate) starting from the fourth injection.
The course of treatment consists of 25–35 injections. If necessary, repeated courses may be administered after 6 months.
DOSAGE FORM
Solution for injection. 2 ml per ampoule. 10 ampoules per pack.
PHARMACOLOGICAL PROPERTIES
The active substances are sodium salts of chondroitin sulfate A and C (average molecular weight 11,000 Daltons). Chondroitin sulfate is a high-molecular-weight mucopolysaccharide and a major component of proteoglycans, which together with collagen fibers form the cartilage matrix.
The drug exerts anti-inflammatory and analgesic effects. It inhibits enzymes responsible for cartilage degradation, including metalloproteinases (notably leukocyte elastase), and reduces hyaluronidase activity. It partially blocks free oxygen radical release and suppresses chemotaxis and antigenic determinants.
The anti-inflammatory and analgesic effects are associated with reduced release of inflammatory and pain mediators into synovial fluid via synoviocytes and synovial macrophages, as well as inhibition of leukotriene B4 and prostaglandin E2 synthesis.
Chondroitin sulfate prevents compression of connective tissue, acts as a lubricant for articular surfaces, normalizes synovial fluid production, improves joint mobility, reduces pain intensity, and improves quality of life.
Pharmacokinetics:
After intramuscular administration, chondroitin sulfate is rapidly absorbed. It is detected in the blood within 30 minutes at significant concentrations. Peak plasma concentration is reached after 1 hour, followed by a gradual decline over 2 days.
It mainly accumulates in articular cartilage. The synovial membrane does not hinder penetration into the joint cavity. It is detected in synovial fluid 15 minutes after intramuscular injection, with maximum cartilage concentration reached after 48 hours.
It is excreted via the kidneys within 24 hours.
CONTRAINDICATIONS
·hypersensitivity to the components of the medicinal product;
·bleeding tendency;
· thrombophlebitis.
- pediatric patients under 18 years
ADVERSE REACTIONS
Skin and subcutaneous tissue disorders: occasionally — erythema, urticaria, dermatitis, maculopapular rash (with or without pruritus), and edema; hemorrhage at the injection site.
Gastrointestinal disorders: in isolated cases — nausea, vomiting.
DRUG INTERACTIONS
Concomitant use of Drastop with nonsteroidal anti-inflammatory drugs (NSAIDs) may allow a reduction in their dose.
An enhancement of the effect of indirect anticoagulants, antiplatelet agents, and fibrinolytics is possible, requiring more frequent monitoring of blood coagulation parameters during combined use.
SPECIAL PRECAUTIONS
Treatment should be discontinued in case of allergic reactions or hemorrhages.
A stable clinical effect requires at least 25 injections of Drastop; however, the therapeutic effect persists for several months after completion of therapy. Repeated courses may be indicated to prevent relapses.
The product contains benzyl alcohol, which may cause toxicity and pseudo-anaphylactic reactions in neonates and children under 3 years of age.
Clinical data in elderly patients with atherosclerosis have shown a reduction in plasma cholesterol and triglyceride levels during chondroitin sulfate therapy.
Use with caution in: patients with coagulation disorders, diabetes mellitus, obesity, low-sodium diets,renal impairment, and women planning pregnancy.
Use during pregnancy and lactation:
The use of the medicinal product is not recommended during pregnancy.
Breastfeeding should be discontinued during treatment due to the lack of data confirming the safety of use in women during this period.
