The drug is used in the treatment of cardiac and bronchial asthma, bronchospasm, chronic bronchitis, decompensated heart failure and paroxysmal nocturnal dyspnoea, angina on exertion , atropine-resistant atrioventricular block develops on the basis of ischemia, it halts the action of dipyridamol, edema, atherosclerotic cerebral circulatory disorders, hypertensive microcirculation disorders, intermittent claudication.
Diaphyllin Venosum containing the active ingredient theophylline is a medicine made in the form of an injectable solution, packed according to specifications, each tube contains 5 ml, 1 box has 5 ampoules. The drug is mixed infusion or used with an electric syringe to allow the slowest rate of drug delivery.
Aminophylline is a complex of theophylline and ethylenediamine. Main action at the cellular level: Theophylline is a drug that will reduce intracellular calcium ions, it also blocks adenosine receptors.
The half-life is prolonged in patients with pulmonary edema, cardiopulmonary disease, liver disease, hypothyroidism, and infections, as well as in the third trimester of pregnancy. Hyperthyroidism and fever shorten the half-life of theophylline.
Treatment of atropine-resistant atrioventricular block that develops on an ischemic basis, suspends the action of dipyridamol, edema, atherosclerotic cerebral circulatory disorders, high-grade microcirculation disorders blood pressure, claudication.

2. Usage of the drug Diaphyllin venosum


2.1. Diaphyllin venosum administration: Diaphyllin venosum is generally eliminated slowly in patients with heart failure, hypoxia in blood and liver, pneumonia, viral infections (especially influenza viruses) and in the elderly. Drugs taken at the same time may increase or decrease theophylline clearance
Must consider, whether there is previous treatment with aminophylin or theophylline (especially long-acting preparations).
Use when: Administer intravenously slowly (over at least 5 minutes) to the patient in the supine position. The patient must lie down for a while after the injection under the supervision of a qualified person.
Dilute the contents of the syringe in 250-500 ml of physiological saline or 5% glucose solution to obtain intravenous drip.
Do not mix the medicine with any other medicine solution. This injectable diaphyllin venosum is to be given by injection or intravenous infusion only.
Sudden increases in serum theophylline concentrations may cause adverse reactions, so plasma concentrations should be monitored.
2.2. Dosage of Diaphyllin venosum: In the emergency : Intravenous slow (over at least 5 minutes) 240 mg aminophylin (1 ampoule) once or twice daily. If plasma theophylline concentration is less than 3 mcg/mL, a bolus of 5-7 mg/kg should be administered intravenously until a plasma concentration of 10 mcg/mL is reached, followed by intravenous drip. (If plasma theophylline concentration is higher than 3 mcg/ml, a dose of 1 mg/kg body weight will increase plasma concentration by 2 mcg/ml). Dosage: If the patient is not currently taking aminophylin or theophylline, use a dose of 5.7 mg/kg, slowly intravenously, at a rate not to exceed 25 mg/min. Maintenance therapy with drip:
If theophylline clearance is normal: 0.5 mg/kg/hour Children 6 months to 9 years: 1 mg/kg/hour Children 10-16 years or Young smokers: 0.8 mg/kg/hour Elderly patients: 0.3 mg/kg/hour If clearance is reduced (eg in patients with heart or liver/kidney failure): 0.3 mg/kg/hour. Use in patients currently taking forms of theophylline For patients currently taking forms of aminophylline, the time, route, and dose of the patient's last dose to determine and review loading dose. A loading dose based on an expected 0.5 mg/kg (body weight) of theophylline would result in a 1 mcg/mL increase in serum theophylline concentration. Therefore, for patients receiving forms of aminophylline, loading doses should be delayed until serum theophylline concentrations can be achieved or clinicians should carefully select doses based on benefits and risks. potential risks.
Then, the intravenous maintenance dose of aminophylline as described above may be considered.
What to do in case of overdose? In the event of an emergency, call 911 immediately or go to the nearest local health station.

Recent myocardial infarction, arrhythmia, ulcerative disease,... Hypersensitivity to the components of the drug. Care should be taken when combining the drug Diaphyllin venosum with: Other aminophylline or purine derivatives (may cause unwanted reactions) such as: Antihypertensive drugs, other xanthine drugs (concurrent use can have may increase drug toxicity). Drugs that block H2 receptors increase the concentration of the drug in the blood plasma. Diaphyllin venosum may stop the effects of diazepam. Diaphyllin venosum is chemically incompatible with the following compounds: Cephalothin, chlorpromazine, codeine, corticotropin, dimenhydrinate, doxapram, dihydralazine, tetracycline given within one hour, pethidine, phenytoin, prochlorperazine esilate, promazine hydrochloride, vancomycin hydrochloride, vancomycin hydrochloride, Precautions for use:
The therapeutic concentration of diaphyllin venosum in plasma is 5 - 20 mg/ml. Because of its direct cardiac and nerve stimulant effects, Diaphyllin can only be administered intravenously, but must be administered very slowly.
In case of oliguria, the dose should be reduced. During the period of taking the drug, the duration of sleep may be reduced. If injected outside a vein or injected into an artery, the drug can cause serious damage, even necrosis. In the case of chronic atrial fibrillation, the use of the drug must be monitored carefully because of the risk of thromboembolism. In the case of people with unstable blood pressure, Diaphyllin should be used as a slow infusion, but blood pressure must be controlled.

Undesirable frequency effects may be reduced with continued treatment and less so with low-dose treatment. In a very small number of patients, caffeine-like adverse effects persist for the duration of aminophyline therapy.

Vascular disorders: Common: hypotension
Rare: sudden hypotension (serum levels above 25 mcg/ ml)
