And whether you know...
The white tablet contains 20 mg of active ingredient of a hydrochloride of Betaksolol in a film cover.
Additional components: Na carboxymethylstarch, Mg stearate, microcrystallic cellulose, monohydrate of lactose, aerosil.
Structure of a cover: polyvinyl alcohol, white opadray-2, titanium dioxide, talc and macrogoal.
1 ml of drops contains 5 mg of active agent of a hydrochloride of Betaksolol.
Additional components: Na hydroxide, chloride benzetoniya, dihydrate of an edetat of dinatrium, Na chloride, water, Acidum hydrochloricum.
Round form in a film cover, with risky, biconvex, a white color. On a section the white kernel is visualized (single impregnations of other flowers are allowed). Tablets Betaksolol are packed on 10 pieces into blisters. In a pack from a cardboard there is an instruction and blisters (1-10).
Slightly yellowish, almost transparent liquid. The tube dropper (1.5-5 ml) is issued in special bottles droppers (5-10 ml) with a sterile cover. In a pack from a cardboard there is an instruction and 1 bottle dropper.
Active component — beta 1 - the adrenoblocker (cardioselective) which is not possessing sympathomimetic internal activity. Slight membranostabiliziruyushchy influence is characteristic of active ingredient.
Betaksolol has hypotensive effect which is reached due to reduction of the stimulating sympathetic impact on peripheral located vessels, and also due to decrease in minute cordial volume.
Cardiodepressive influence is not characteristic of therapeutic dosages. Active component does not promote a delay of ions of Na in an organism, does not reduce bronchodilatory activity of beta-adrenergic agonists, does not exert impact on a glucose metabolism. Long influence is characteristic.
Eye drops at topical administration are capable to reduce an indicator of intraocular pressure. Resorptive activity is expressed slightly.
Pharmacodynamics and pharmacokinetics
95% of the dose accepted by per os quickly are absorbed from a gleam of a digestive tract. The effect of "the first passing" through hepatic system is characteristic. The indicator of Cmax is registered in 1-2 hours. Contacts plasma proteins for 50%. The indicator of Vd is equal to 6 l/kg. The elimination half-life is equal to 15-20 hours. A preferential way of removal of metabolites – through renal system; about 10-15% of a medicine are removed in original state.

Sense bodys, nervous system:
- emotional lability;

Other negative reactions:
- skin rashes;
- psoriasis; aggravation
- allergic answers;
- increase of ALT, nuclear heating plant and other enzymes of hepatic system;
- change of body weight;
- increase of level of cholesterol.
Negative reactions when using eye drops:
- system reactions;
- spotty okrashennost of a cornea;
- feeling of a foreign body in an eye;

Betaksolol, application instruction (Way and dosage)
The tableted form is intended for system use, and eye drops – for local.
Tablets appoint per os on 20 mg a day. To patients who are on a dialysis (peritoneal) a hemodialysis (constant), originally appoint 10 mg a day. The choice of time of reception is carried out depending on the mode of holding dialysis sessions.
Drug Betaksolol in the form of eye drops is appointed twice a day on 1 drop in the affected eye. The first month of therapy demands obligatory control over an indicator of intraocular pressure. Further measurement of this parameter is carried out in an individual order.
Use of high doses can provoke:
- acute heart failure;
- convulsive syndrome;
At poisoning carrying out actions for washing of a digestive tract is required, purpose of enterosorbiruyushchy medicines is effective (Polisorb, Absorbent carbon). At cordial blockade carrying out transvenous stimulation is possible. As symptomatic therapy intravenously enter 1-2 mg of Atropine, cardiotonics (Dobutaminum, the Dopamine, Epinephrinum, Norepinephrinum), beta-adrenergic agonists (Izoprenalin), sedatives (Diazepam, Lorazepam). The hemodialysis is recognized as ineffective.
Decrease in efficiency of Betaksolol at simultaneous therapy is noted by Xanthine derivatives, at treatment of an adrenomimetikama. Absorption of active agent considerably decreases at reception of antidiarrheal medicines and antacids. Other anti-hypertensive drugs strengthen hypotensive influence of a medicine. Strengthening of a negative inotropic effect when using galogensoderzhashchy narcotic means is observed.
Betaksolol is capable to prolong action of not depolarizing muscle relaxants. Glucocorticosteroids and NPVS reduce expressiveness of hypotensive effect of Betaksolol. Cardiac glycosides strengthen bradycardia, characteristic of a medicine. The risk of development of an orthostatic form of hypotonia increases at treatment by tricyclic antidepressants (Imipraminum).
Disturbance of conductivity and strengthening of expressiveness of negative inotropic impact at topical administration of eye drops at patients with glaucoma which at the same time accept Verapamil, Amiodaronum, beta adrenoblockers, Diltiazem is possible. Betaksolol is capable to increase concentration of Lidocaine in blood. Sulfasalazinum increases Betaksolol's level in blood. Strengthening of bradycardia and noticeable lowering of blood pressure at reception of the medicines capable to exhaust stocks of catecholamines is noted (including Reserpinum).
Terms of sale
The medicine is released in pharmaceutical points. It is optional to show the prescription form.
Restriction on temperature condition – to 25 degrees. It is recommended to store in the dark place.
Period of validity
At a medium-weight current of HOBL, bronchial asthma therapy by Betaksolol is begun with small dosages, controlling indicators of functions of external respiration. Attacks are stopped beta 2 - adrenomimetikami. At stenocardia, an ischemic heart disease cancellation of a medicine is carried out gradually.
Active agent is not capable to change the pupil size therefore to patients who suffer from a zakrutougolny form of glaucoma in addition appoint miotik. System reactions, and also the additive effects from intraocular pressure at a simultaneous primeniye of the eye drops containing Betaksolol and reception of per os of beta adrenoblockers are possible. Before planned operative measures medicine is cancelled.
Carrying contact lenses when using eye drops Betaksolol is inadmissible. It is not recommended to apply in pediatric practice.
