Characteristics of the drug Losek

Losek is an anti-ulcer agent, an inhibitor of H + K + -ATPase. It blocks the last stage of hydrochloric acid production, inhibits stimulated and basal secretion. The therapeutic effect of the drug depends on the dose (the higher it is, the better the effect).

Taking Losek along with antibiotics contributes to the destruction of Helicobacter pylori. As a result, the damaged mucous membranes heal, the risk of bleeding decreases, the symptoms of the disease disappear, and stable remission is achieved. When using medication there is no need for long-term anti-ulcer treatment.

Characteristics of the drug Losek Mappes

Losek Maps is produced by the same manufacturer and contains the same active ingredient. Therefore, the drug acts by analogy with Losek: it blocks the formation of hydrochloric acid, destroys Helicobacter pylori, improves the condition of the gastrointestinal tract. The maximum therapeutic effect is achieved within 4 days from the start of therapy.

Differences in drugs less, but they exist. They are:

  1. Release form. Losek is produced in the form of a lyophilisate (powder) from which an infusion solution is prepared. Losek Maps is sold in tablets containing 10, 20 or 40 mg of active ingredient.
  2. Mode of application. Losec is injected into a vein for 20-30 minutes. Before that, it is dissolved in 100 ml of solution (Dextrose 5% or Sodium Chloride 0.9%). Tablets are used in the morning, before meals or during it. If the patient cannot swallow the tablet whole, it is dissolved in water or acidified liquid (fruit juice will do). The finished solution is drunk within half an hour after preparation. The duration of the course and dosage depend on the diagnosis, the presence of comorbidities.

What's better

Preparations contain 1 active ingredient and are equally effective. The solution causes fewer side reactions, but it is more difficult to use because of the release form.

The main contraindication to the use of drugs - idiosyncrasy of substances within their composition. Experience with omeprazole in children is limited, so patients in this age group are rarely prescribed. The use of drugs during periods of gestation (pregnancy) and lactation is possible according to indications.

Before starting treatment, you need to make sure that there are no malignant diseases (drugs mask the symptoms of such pathologies and make it difficult to diagnose).

With impaired hepatic function, the bioavailability of omeprazole and its half-life increase. Therefore, these patients are prescribed drugs in a daily dose of 10-20 mg.

Alexandra, gastroenterologist, Moscow: “Proton pump inhibitors are effective for ulcers, heartburn, reflux esophagitis and other pathologies.

Anatoly, 43, Rostov-on-Don: “Severe pain in the stomach made me consult a doctor. Passed an examination, the results of which were diagnosed with peptic ulcer. Gastroenterologist advised to take Losek Maps - 1 time per day, 20 mg. After a few days, the symptoms became less pronounced, and then disappeared completely. The total duration of treatment was 1 month. ”

Anastasia, 50 years old, Yekaterinburg: “Losek was injected in the hospital with a peptic ulcer. The improvement came quickly, in a few days. After being discharged from the hospital, she continued to use the drug in pills. It was difficult to swallow, so I dissolved them in water before taking. ”
