Current Pain and Headache Reports
|May 14, 2008
Summary
Cluster headache (CH) is a severe primary headache disorder. Medication-overuse headache (MOH) can complicate CH, particularly in patients with a migraine history, requiring careful monitoring and potential medication withdrawal.
Area of Science:
- Neurology
- Headache Medicine
Background:
- Cluster headache (CH) is recognized as the most severe primary headache disorder.
- Optimal CH care faces challenges like misdiagnosis, delayed diagnosis, undertreatment, and mismanagement.
Observation:
- Medication-overuse headache (MOH) can complicate CH, manifesting as increased headache frequency or a background headache.
- A history of migraine, either personal or familial, is strongly linked to MOH development in CH patients.
Findings:
- Patients with CH and a migraine history are at higher risk for developing MOH.
- MOH in CH can present with a featureless or migrainous background headache.
Implications:
- Careful monitoring for MOH is crucial in all CH patients, especially those with a migraine history.
- Medication withdrawal should be considered for CH patients exhibiting MOH features to improve management outcomes.

01:27Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...
01:24Parkinson's Disease: Treatment
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

01:24Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
01:29Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists
Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.

01:19Management of Insomnia
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
01:02Prescription, Nonprescription and Orphan Drugs
Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...
