			== Triptan ==

			Triptans are a class of [[medication]]s used primarily in the treatment of [[migraine]]s and [[cluster headache]]s. They are selective [[serotonin receptor agonist]]s that act on the 5-HT<sub>1B</sub> and 5-HT<sub>1D</sub> receptors. Triptans are known for their ability to relieve headache symptoms and are considered effective for many patients.

			== Mechanism of Action ==

			Triptans work by stimulating the 5-HT<sub>1B</sub> and 5-HT<sub>1D</sub> receptors in the brain. This action leads to the constriction of dilated blood vessels in the brain, which is believed to be a primary cause of migraine headaches. Additionally, triptans inhibit the release of pro-inflammatory neuropeptides, such as [[calcitonin gene-related peptide]] (CGRP), which further contributes to their effectiveness in reducing migraine symptoms.

			== Indications ==

			Triptans are primarily indicated for the acute treatment of migraine attacks with or without [[aura (symptom)\|aura]]. They are also used in the management of cluster headaches. Triptans are not intended for use as a preventive treatment for migraines or headaches.

			== Administration ==

			Triptans are available in various forms, including oral tablets, nasal sprays, and subcutaneous injections. The choice of formulation depends on the patient's preference, the severity of the migraine, and the speed of onset required. For example, nasal sprays and injections may provide faster relief compared to oral tablets.

			== Side Effects ==

			Common side effects of triptans include dizziness, fatigue, dry mouth, and sensations of tingling or warmth. Some patients may experience more serious side effects, such as chest pain or tightness, which may require immediate medical attention. Triptans are contraindicated in patients with certain cardiovascular conditions due to the risk of vasoconstriction.

			== Contraindications ==

			Triptans should not be used in individuals with a history of [[ischemic heart disease]], [[cerebrovascular disease]], or uncontrolled [[hypertension]]. They are also contraindicated in patients with hemiplegic or basilar migraines. Caution is advised when triptans are used in combination with other serotonergic drugs due to the risk of [[serotonin syndrome]].

	~~'''Toxic encephalopathy''' is a neurologic disorder caused by exposure to neurotoxic agents such as organic solvents, heavy metals, carbon monoxide, and certain~~ medications~~. It can result in a wide range of neurologic symptoms, from mild cognitive impairment~~ to ~~severe dementia.~~		{{Short description\|Class of medications used to treat migraines}}
			{{Drug class}}

	~~== Causes ==~~		'''Triptans''' are a class of [[medication]]s used primarily in the treatment of [[migraine]]s and [[cluster headache]]s. They are [[serotonin receptor agonist]]s that act on the 5-HT<sub>1B</sub> and 5-HT<sub>1D</sub> receptors in the brain, leading to the constriction of blood vessels and the inhibition of pro-inflammatory neuropeptide release.
	~~Toxic encephalopathy can be caused by~~ a ~~variety~~ of ~~substances, including~~ [[~~organic solvents~~]], [[~~heavy metals~~]], [[~~carbon monoxide~~]]~~, and certain~~ [[~~medications~~]]~~. These substances can damage~~ the brain ~~either through direct toxicity or by causing an immune response that leads~~ to ~~inflammation~~ and ~~damage to brain tissue~~.

	== ~~Symptoms~~ ==		==Mechanism of action==
	~~The symptoms of toxic encephalopathy can vary widely~~, ~~depending on~~ the ~~specific toxin involved~~ and the ~~extent~~ of the ~~exposure. They can range from mild cognitive impairment to severe dementia. Other possible symptoms include confusion~~, ~~memory loss~~, ~~personality changes, fatigue, headache, and difficulty concentrating~~.		Triptans work by stimulating the [[serotonin]] (5-HT) receptors in the brain, specifically the 5-HT<sub>1B</sub> and 5-HT<sub>1D</sub> subtypes. This action results in the constriction of cranial blood vessels and the inhibition of the release of pro-inflammatory neuropeptides, such as [[calcitonin gene-related peptide]] (CGRP), which are believed to play a role in the pathophysiology of migraines.

	== ~~Diagnosis~~ ==		==Uses==
	~~The diagnosis~~ of ~~toxic encephalopathy is often challenging, as the symptoms can be nonspecific and can mimic other neurologic disorders~~. ~~The diagnosis is usually based on a combination of~~ the ~~patient's history~~ of ~~exposure to~~ a ~~potential neurotoxic agent, the presence of characteristic symptoms, and the exclusion of other possible causes~~.		Triptans are primarily used to treat acute migraine attacks with or without [[aura (symptom)\|aura]]. They are also used in the treatment of cluster headaches. Triptans are most effective when taken early in the course of a migraine attack.

	== ~~Treatment~~ ==		==Side effects==
	~~The treatment~~ of ~~toxic encephalopathy primarily involves removing the source of the toxin~~ and ~~providing supportive care~~. ~~In some cases~~, ~~medications may be~~ used ~~to help manage symptoms. The prognosis for recovery depends on the extent of the exposure and the severity of the symptoms~~.		Common side effects of triptans include [[dizziness]], [[drowsiness]], [[nausea]], and [[dry mouth]]. More serious side effects can include [[chest pain]], [[hypertension]], and [[serotonin syndrome]], especially when used in combination with other serotonergic drugs.

	== ~~See also~~ ==		==Contraindications==
	* [[~~Neurotoxicity~~]]		Triptans are contraindicated in individuals with a history of [[ischemic heart disease]], [[cerebrovascular disease]], [[uncontrolled hypertension]], and certain types of [[migraine]] such as [[hemiplegic migraine]].
