There will be new approvals for metoclopramide drops again from August 2015. They will be available again in pharmacies at 1 mg/ml with a different indication and duration of therapy. The MCP solution 1 mg/ml is approved in adults for the treatment of nausea and vomiting (as a so-called antiemetic) associated with chemotherapy, as well as for the prevention of these symptoms caused by radiation therapy or acute migraines.

In contrast to before, the active ingredient concentration is now only a quarter. Therefore, dosing is no longer done using a dropper, but rather with a graduated pipette. It contains 5 ml, for the recommended single dose for adults, so for 10 mg you need to take two full pipettes. The preparations should be reimbursable.

Five further approval applications for MCP in a concentration of 1 mg/ml and the dosage form “oral solution” are pending at the Federal Institute for Drugs and Medical Devices (BfArM).

Background: Many migraine patients were able to use MCP to effectively and tolerably treat nausea and vomiting and also improve gastric motility. However, in April 2014, the approvals for all finished medicinal products containing metoclopramide in drop form with a concentration higher than 1 mg/ml were revoked. The preparations were withdrawn from the market. All indications for chronic complaints no longer apply as a result of the revocation of the approval. For many migraine sufferers this came as a surprise and other options were often not effective or tolerated.

Antiemetics normalize gastrointestinal motility and relieve nausea and vomiting. Metoclopramide (MCP) was recommended in a standard adult dose of 20 drops. Fatigue, dizziness or diarrhea are rare undesirable effects. Very rarely, movement disorders in the form of involuntary mouth movements, throat and tongue spasms, head turning, difficulty swallowing or turning of the eyes can occur shortly after ingestion.

Metoclopramide drops (MCP) with an active ingredient content of more than 1 mg/ml were no longer marketable. You have been called back. The preparations available in Germany all contained concentrations between 4 and 5 mg/ml. They were all affected by this.

The reassessment is based on the known risk of significant cardiovascular and neurological side effects, particularly extrapyramidal symptoms and irreversible tardive dyskinesia. This risk increases with the dose used and duration of treatment.

The newly approved metoclopramide drops from August 2015 now have a weaker concentration of 1 mg/ml. The maximum dosage for adults is now 30 mg or 0.5 mg/kg body weight per day. For children, dosage is based on body weight. 0.1 to 0.15 mg/kg body weight up to three times daily is recommended. The maximum dose within 24 hours in children is also 0.5 mg/kg body weight. The duration of therapy was limited to a maximum of five days. All indications for chronic symptoms have been eliminated as a result of the revocation of the approvals.

Loss of appetite, nausea and vomiting can be symptoms of migraine attacks. In addition, the muscles of the stomach are often impaired in their locomotion function. So-called antiemetics (Latin: emesis = vomiting) are intended to correct these functional disorders in migraines. The reduced gastric motility during migraines also means that the usual migraine medications taken as tablets are difficult to transport further into the intestine. The desired effect will then not be achieved. For this reason, so-called antiemetics are recommended to treat migraine attacks. This is intended to normalize the control of stomach motility again and improve the effectiveness of the migraine medication.

Domperidone and dimenhydrinate are still available as alternatives for the treatment of nausea and vomiting during migraine attacks.

Domperidone has antiemetic and prokinetic effects. Domperidone has fewer extrapyramidal motor side effects than metoclopramide. Taken in the prodromal phase of migraine, domperidone reduced the likelihood of a subsequent headache phase of migraine in two studies. Domperidone is available as a tablet and suspension. The assessment of the prokinetic drug domperidone (e.g. Motilium) has also been revised. The indications were limited to the symptomatic treatment of nausea and vomiting. Adults weighing more than 35 kg should only use domperidone in a maximum dosage of 10 mg orally up to three times a day or up to 30 mg rectally twice a day. Children and adolescents weighing less than 35 kg should only receive domperidone orally at a maximum dose of 0.25 mg per kg body weight up to three times daily. Domperidone should not be used for longer than a week. The reason is cardiac side effects of domperidone. Cardiac arrhythmias, such as life-threatening QT prolongations, have long been known as undesirable effects; Domperidone should therefore only be used with caution in patients with heart disease or electrolyte disorders.

Dimenhydrinate is antiemetic but not prokinetic. Dimenhydrinate is therefore only the drug of second choice in the treatment of migraine attacks, unless the sedative side effect is desired. Dimenhydrinate is available as a dragee, syrup, chewable tablet, suppository and for IV and IM injection.
