Cooperation.
Incompatible with alcohol, MAO inhibitors (strengthening the psychostimulant effects). Reduces the effectiveness of phenytoin. Anticholinergics, phenothiazines and benzodiazepines increase the sedative and central holinoliticheskoy activity imipramine.
Overdose.
Symptoms: dizziness, excitation, ataxia, convulsions, stupor, coma, midriaz, tachycardia, arrhythmia, OF блокада, collapse at high venous pressure, hypotension, respiratory depression, cyanosis, vomiting, fever.
Treatment: gastric lavage with saline, inside-activated carbon, in / in the slow introduction of physostigmine salicylate, symptomatic treatment (anticonvulsants).
Dosing and Administration.
Inside, within 10-14 days dose gradually increased to 150-250 mg/day and after clinical effect gradually reduced to a supporting-50-150 mg. In shallow depressions — 75-150 mg/day, supporting is 25-50 mg/day. Children 3-6 years 1 h to sleep — 5 mg; 7-12 years - 25 mg.
/ M - By 25 mg 3 times a day in combination with oral intake 25 mg, daily dose can be increased to 25 mg. Through 7 Days begin reducing the dose to maintenance (by 25 mg / day) and inside designated 50 mg. With 13 days only oral appointment — 350 mg / day 3 admission.
Precautions.
In the initial period of therapy necessarily constant medical monitoring of patients with suicidal tendencies. During treatment, it prohibits the use of alcoholic beverages. It is recommended to control the cells of peripheral blood and liver function. Appoint follows through 2 Sun (no sooner) after discontinuation of MAO inhibitors, start with small doses — 25 mg / day. When using diabetic patients require dose adjustment of oral antidiabetic drugs. It will be appreciated, injection that contains sulfites, that can cause or exacerbate type reaction anaphylaxis. In the initial period of therapy is necessary to give up driving and the performance of potentially hazardous work.
Cooperation
Active substance | Description of interaction |
Altretamïn | FMR: synergism. Against the background of Altretamine enhanced hypotensive effect and increased risk of orthostatic hypotension. |
Glipizide | FKV. FMR. Against the background of imipramine, more tightly bound to proteins, enhanced effect (may develop hypoglycemia). |
Diazepam | FMR: synergism. Increases sedatives and central holinoliticheskoe Activity. Against the background enhances the effect of imipramine. |
Zolpidem | FKV. FMR. Decreases (on 20%) concentration in the blood. Against the background of imipramine increased speed reduction of psychomotor reactions. |
Clonazepam | FMR: synergism. Increases sedatives and central holinoliticheskoe Activity. Against the background enhances the effect of imipramine. |
Klonidin | Against the background of reduced hypotensive effect of imipramine. |
Lorazepam | FMR: synergism. Increases sedatives and central holinoliticheskoe Activity. Against the background enhances the effect of imipramine. |
Nitroglycerin | FKV. Against the background of imipramine, attenuating salivation and causes dryness in the mouth, difficult sublingual absorption. |
Risperidone | FKV. Against the background of imipramine (reduces the activity of SYP2D6) slows down the formation of 9-gidroksirisperidona is the main active metabolite. |
Rifampicin | FKV. Accelerates biotransformation. |
Salmeterol | FMR: synergism. Amid imipramine enhanced action on the vascular system (may cause arrhythmias, tachycardia, severe hypertension or hyperpyrexia); concurrently or sequentially with the appointment of caution. |
Selegiline | FMR: synergism. Strengthens (mutually) therapeutic and side effects; joint or sequential designation (not recommended) can cause changes in behavioral and mental status, bouts of sweating, muscle rigidity, hypertension, fainting, asystole. |
Tramadol | FKV. FMR. Against the backdrop of slowing down the elimination of imipramine, It increases the risk of phenomena relative overdose, incl. seizures. |
Phenytoin | FMR: antagonizm. Against the background of declining anticonvulsant effect of imipramine. |
Fluoxetine | FKV. It inhibits the activity of CYP2D6 isoenzyme, slows biotrasformatsiyu, increases the concentration in the tissues, It increases the risk of toxic effects. If the patient is receiving fluoxetine or previous 5 weeks, treatment with imipramine, have a low therapeutic index, you need to start with small doses. |
Ethanol | Against the background of enhanced CNS depression with imipramine. During treatment it is necessary to exclude the use of alcoholic beverages. |
