Bulbocapnine

Bulbocapnine is an alkaloid found in Corydalis and Dicentra, herbs in the family Fumariaceae that can cause fatal poisoning in sheep and cattle. It has been shown to act as an acetylcholinesterase inhibitor, and inhibits biosynthesis of dopamine via inhibition of the enzyme tyrosine hydroxylase. It has been used in the treatment of muscular tremors and vestibular nystagmus.

Properties Suppliers
Bumadizone

Bumadizone is a non-steroidal anti-inflammatory drug.

Properties Suppliers
Bunazosin

Bunazosin is an alpha 1 antagonist. It was initially developed to treat benign prostatic hyperplasia. It has been approved in Japan in a topical form to treat glaucoma. The mechanism of action is a reduction of aqueous outflow through the uveoscleral pathway resulting in lowering the intraocular pressure. It also may act to improve blood flow to the ocular nerve.

Properties Suppliers
Bupivacaine

Bupivacaine is a local anaesthetic drug belonging to the amino amide group. Bupivacaine is indicated for local anesthesia including infiltration, nerve block, epidural, and intrathecal anesthesia. Bupivacaine often is administered by epidural injection before total hip arthroplasty. It also is commonly injected to surgical wound sites to reduce pain for up to 20 hours after the surgery. Bupivacaine binds to the intracellular portion of sodium channels and blocks sodium influx into nerve cells, which prevents depolarization.

Properties Suppliers
Bupranolol

Bupranolol is a non-selective beta blocker without intrinsic sympathomimetic activity, but with strong membrane stabilizing activity. Its potency is similar to propranolol. It can be used to treat hypertension and tachycardia.

Properties Suppliers
Buprenorphine

Buprenorphine is a semi-synthetic opioid that is used to treat opioid addiction in higher dosages and to control moderate pain in non-opioid tolerant individuals in lower dosages. It is a Bentley-derivative opioid of the phenanthrene-morpholine class with extremely high binding affinity at the µ- and κ-opioid receptor. It has partial agonist activity at the µ-opioid receptor, partial or full agonist activity at the nociceptin and δ-opioid receptor, and competitive antagonist activity at the κ-opioid receptor.

Properties Suppliers
Bupropion Hydrochloride

Bupropion Hydrochloride is an antidepressant of the aminoketone class, is chemically unrelated to tricyclic, tetracyclic, selective serotonin re-uptake inhibitor, or other known antidepressant agents. Its structure closely resembles that of diethylpropion. It is related to phenylethylamines. Bupropion hydrochloride powder is white, crystalline, and highly soluble in water. It has a bitter taste and produces the sensation of local anesthesia on the oral mucosa.

Properties Suppliers
Burimamide

Burimamide is an antagonist at the H2 and H3 histamine receptors. It is a thiourea derivative. It was first developed by scientists at Smith, Kline & French in their intent to develop a histamine antagonist for the treatment of peptic ulcers.

Properties Suppliers
Buscaline

Buscaline is a lesser-known psychedelic drug. It is an analog of mescaline. It was first synthesized by Alexander Shulgin. It produces no psychedelic or psychoactive effects, but causes heart arrythmia and light diarrhea. It does not cause any visuals or insights.

Properties Suppliers
Buspirone

Buspirone is an anxiolytic psychoactive drug of the azapirone chemical class. It is primarily used to treat generalized anxiety disorder (GAD). Buspirone was first identified by a team at Mead Johnson in 1972. Buspirone is used to treat symptoms of anxiety, such as fear, tension, irritability, dizziness, pounding heartbeat, and other physical symptoms. Buspirone is not an anti-psychotic medication and should not be used in place of medication prescribed by your doctor for mental illness. Buspirone is thought to work by decreasing the amount and actions of a chemical known as serotonin in certain parts of the brain.
