Pharmacological action


Lidokain is quickly absorbed through a mucous membrane of an urethra. Peak concentration in blood plasma in 0,06 0,2 mkg/ml of lidocaine are reached in 45 60 minutes after intra urethral introduction of 10 – 40 ml of lidocaine of gel of 2% (200 – 800 mg of lidocaine). Lidocaine is quickly distributed on all fabrics. Lidocaine approximately for 65% is attached with proteins of blood plasma and acid alpha 1 – to glycoproteins (AAG). About 90% of a dose of lidocaine are metabolized in less active metabolites. Elimination half-life – 1.8 hours, it can be prolonged at elderly people till 2.3 o’clock. The half-life period of active metabolites is 0.9 hours. Less than 5% of lidocaine are allocated invariable with urine. It is necessary to consider that at the significant inflammation of a mucous membrane of an urethra the absorption of lidocaine increases

Chlorhexidin. Only very small quantities of a chlorhexidin are absorbed after topical administration.

The pharmacodynamics

Katedzhel with lidocaine is the sterile and antiseptic gel with local anesthetic effect intended for instillation in an urethra. It reduces the pain connected with transurethral procedures and substantially prevents infections of urinary tract after catheterization.

Lidocaine is local anesthetic. Its action begins in 5 10 minutes, and the effect lasts 20 30 minutes.

Chlorhexidin has antimicrobic effect against many gram-positive (Staphylococcus aureus Streptococcus salivarius Staphylococcus epidermidis) and gram-negative bacteria (Micrococcus pyogenes, E. coli, Pseudomonas pyocyanea and Salmonella typhi, E. coli, Pseudomonas aeruginosa) and also against a number of mushrooms (Candida utilis) and viruses. In this concentration he is applied to prevention of the ascending infection of an upper urethra and a bladder.

– to open the blister, removing paper from the transparent body (whenever possible only to a banner)

– to break off a tip of a protective cap without considerable effort (whenever possible even in packing). At the same time it is necessary to track that the tip was removed completely, in order to avoid damage mucous an urethra. For simplification of input of an application cone it is recommended to squeeze out previously Katedzhel’s drop
