Pharmacotherapeutic group: venoactive agent, antivaricose drug
ATC code: C05BX01
Calcium dobesilate acts on the capillary walls by correcting their impaired physiological functions — increased permeability and decreased resistance. It enhances erythrocyte flexibility, inhibits platelet aggregation, and in diabetic retinopathy reduces plasma and blood viscosity, thereby improving the rheological properties of the blood and tissue perfusion. These properties help correct capillary dysfunction, whether functional or caused by congenital or acquired metabolic disorders. Calcium dobesilate also helps reduce oedema.
⚠️ Warnings
In cases of severe renal impairment requiring dialysis, the dose may be reduced.
In very rare cases, administration of calcium dobesilate may cause agranulocytosis (see section 4.8). In such cases, symptoms may include high fever, oral cavity infections (tonsillitis), sore throat, anogenital inflammation, and other signs typical of infection. If any of these symptoms occur, treatment must be discontinued. A complete blood count and leukogram should then be performed immediately.
Doxium 500 may trigger serious hypersensitivity reactions (anaphylactic reaction or shock). In the event of hypersensitivity reactions, treatment must be discontinued.
Elderly patients
The elderly population was well represented in clinical studies with calcium dobesilate, and no concerns regarding overall safety have emerged.
Paediatric population
No studies on the use of calcium dobesilate in the paediatric population have been conducted.
