Characteristics of the substance Dihydroergotamine

Refers to the group of hydrogenated derivatives of ergot alkaloids. Colorless transparent solution.

Pharmacology

Pharmacological action - vasodilator, antimigraine.

Stimulates 5-HT1D serotonin receptors, blocks alpha1 and alpha2-adrenergic receptors of blood vessels. It is a vasoconstrictor of intracranial vessels and has pronounced neuroinhibitory properties. Reduces photo and phonophobia. Somewhat increases the tone of the veins. When inhaled (nasal spray) is quickly absorbed, which ensures its high effectiveness (arresting migraine attack in 20-30 minutes), and is excreted from the body (less risk of unwanted effects). When taken orally (tablets), bioavailability is reduced. After the / m introduction, the effect manifests itself in 15-30 minutes and lasts for 3-4 hours.

Application of the substance Dihydroergotamine

Arteriogipotonichesky variant of a headache, migraine, vasospastic angina, orthostatic hypotension.

Contraindications

Hypersensitivity, severe atherosclerosis, organic heart lesions, myocardial infarction, arterial hypertension, peripheral circulatory disturbance, sepsis, shock, impaired renal function, I trimester of pregnancy, breast-feeding (at the time of treatment, breastfeeding is compulsory).

Application in pregnancy and lactation

The action category for fetus by FDA is X.

Side effects of the substance Dihydroergotamine

Nausea, vomiting, diarrhea, difficulty in nasal breathing, rhythm disturbances (rarely), dizziness, swelling, itching.

Interaction

The effect is enhanced by antihistamines, sedatives and hypnotics. Simultaneous use with other antimigrenous drugs (ergotamine, sumatriptan) increases the likelihood of vasospasm. Strengthens the effect of certain antihypertensive drugs. Macrolides increase the concentration of dihydroergotamine in the blood.

Overdose

In the presence of hypersensitivity to ergotamine drugs, symptoms of ergotism may appear - chest pain, respiratory depression, muscle weakness, pain and paresthesia in the extremities, accompanied by cyanosis and impaired pulsation in peripheral vessels, marked ischemic changes in the fingers and feet (rarely), vomiting, diarrhea , Delirium, convulsions, coma.

Treatment: emergency cancellation of the drug, local warming compresses, the appointment of vasodilators (nitroprusside sodium, phentolamine), careful care to prevent tissue damage.

Routes of administration

Inside, IM, SC.

Precautions for the substance Dihydroergotamine

During treatment, smoking is not recommended (the risk of spasmodic peripheral vessels increases).
