Carisoprodol

Carisoprodol is a centrally acting skeletal muscle relaxant of the carbamate class, sold chiefly under the brand name Soma. It is prescribed for short-term relief of acute musculoskeletal pain, usually alongside rest and physical therapy. Much of its effect comes from its sedative action on the central nervous system, and because it is broken down into the controlled sedative meprobamate and carries a risk of dependence and abuse, it is a scheduled controlled substance in the United States.

Antihistamine

Hydroxyzine

Hydroxyzine is a first-generation antihistamine of the piperazine class, one of the oldest antihistamines still in wide use. Because it blocks histamine H1 receptors and readily enters the brain, it serves both for allergic itching and hives and as a sedating anti-anxiety medication and pre-procedure premedication. It is sold under brand names such as Atarax and Vistaril, and the body converts part of it into cetirizine, itself a well-known antihistamine.

Levodopa + Carbidopa

Levodopa + carbidopa is a fixed-dose combination medication used chiefly to treat Parkinson's disease. Levodopa is a precursor that the brain converts into dopamine, the neurotransmitter that is depleted in the disease, while carbidopa prevents levodopa from being broken down before it reaches the brain. Sold under brand names such as Sinemet, the pairing remains the most effective symptomatic treatment for Parkinson's disease.

Muscle Relaxant

Methocarbamol

Methocarbamol is a centrally acting skeletal muscle relaxant used to relieve the discomfort of acute muscle spasm and musculoskeletal pain. A carbamate related to the older agent mephenesin, it works within the central nervous system rather than acting directly on muscle, and it is typically prescribed for short periods alongside rest and physical therapy. Introduced in the late 1950s, it is available generically and is sometimes given by injection in the hospital management of conditions such as tetanus.

Analgesic

Paracetamol

Paracetamol, known as acetaminophen in the United States, is one of the most widely used pain and fever medicines in the world, relieving mild to moderate pain with little of the stomach irritation seen with nonsteroidal anti-inflammatory drugs. Remarkably, after more than a century its exact mechanism is still debated; a leading explanation is that in the brain it is converted to a metabolite, AM404, that acts on the endocannabinoid and TRPV1 systems and inhibits central prostaglandin synthesis, and AM404 has been detected in human cerebrospinal fluid after a normal dose. Very safe at recommended doses, it can cause severe liver injury in overdose and is a leading cause of acute liver failure; a widely discussed concern about prenatal use and child neurodevelopment was substantially weakened by a large sibling-controlled study pointing to familial confounding rather than causation.

Anticonvulsant

Primidone

Primidone is an anticonvulsant medication of the barbiturate family, used to treat epilepsy and, very commonly, essential tremor. In the body it is partly converted into phenobarbital and another active metabolite, so a large part of its effect comes from these breakdown products. Introduced in the 1950s and sold under the brand name Mysoline, it remains a first-line option for essential tremor and is available as an inexpensive generic.

Dopaminergic

Ropinirole

Ropinirole is a non-ergoline dopamine agonist, a drug that mimics the action of dopamine at its receptors in the brain. It is used mainly to treat Parkinson's disease and moderate to severe restless legs syndrome. Taken by mouth, it is sold under brand names such as Requip.

Anticonvulsant

Sodium Valproate

Sodium valproate is the sodium salt of valproic acid and one of the principal forms of the drug valproate, a widely used anticonvulsant and mood stabilizer. It is prescribed for several types of epilepsy, for the manic phase of bipolar disorder, and for the prevention of migraine. Valproate carries strong warnings because it can cause serious birth defects and developmental problems when taken during pregnancy.

Blend

Sodium Valproate + Valproic Acid

Sodium valproate combined with valproic acid is the formulation known as valproate semisodium or divalproex sodium, sold chiefly under the brand name Depakote. It is a stable one-to-one complex of the two forms that dissociates in the gut to release the same active valproate ion. It is used as an anticonvulsant and mood stabilizer, most notably for the manic episodes of bipolar disorder, and is often chosen for its gentler effect on the stomach.

Anticonvulsant

Topiramate

Topiramate is an anticonvulsant medication used to treat epilepsy and to prevent migraine headaches, and in combination with phentermine it is also used for weight management [1][2]. Chemically unusual for a drug, it is a sulfamate-substituted derivative of the sugar fructose. Discovered in the 1980s and approved in the United States in 1996, it is sold under brand names including Topamax and, in the weight-loss combination, Qsymia.

Hypnotic

Zaleplon

Zaleplon is a nonbenzodiazepine hypnotic of the pyrazolopyrimidine class, one of the so-called Z-drugs used for the short-term treatment of insomnia. It was approved in the United States in 1999 and is sold under brand names including Sonata. Because it has an unusually short duration of action, it is used mainly to help people fall asleep, including for awakenings in the middle of the night.
