Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade.
Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS.
A class of drugs that act by selective inhibition of calcium influx through cellular membranes.
Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus.
Drugs that bind to but do not activate DOPAMINE RECEPTORS, thereby blocking the actions of dopamine or exogenous agonists. Many drugs used in the treatment of psychotic disorders (ANTIPSYCHOTIC AGENTS) are dopamine antagonists, although their therapeutic effects may be due to long-term adjustments of the brain rather than to the acute effects of blocking dopamine receptors. Dopamine antagonists have been used for several other clinical purposes including as ANTIEMETICS, in the treatment of Tourette syndrome, and for hiccup. Dopamine receptor blockade is associated with NEUROLEPTIC MALIGNANT SYNDROME.
Drugs that act on adrenergic receptors or affect the life cycle of adrenergic transmitters. Included here are adrenergic agonists and antagonists and agents that affect the synthesis, storage, uptake, metabolism, or release of adrenergic transmitters.

DescriptionTetrahydropalmatine can be prepared from the total bases of tetrahydroxy berberine. Tetrahydropalmatine can be used to prepare palmatine. Palmatine has a broad-spectrum antibacterial effect, especially against Candida albicans. It can be used clinically to treat gynecological inflammation, bacillary dysentery, enteritis, respiratory and urinary tract infections, surgical infections, and conjunctivitis. Palmatine can also enhance the relaxation of the body's norepinephrine smooth muscle. Tetrahydropalmatine, an active component isolated from corydalis, acts through inhibition of amygdaloid release of dopamine to inhibit an epileptic attack in rats.
UsesDL-Tetrahydropalmatine is the main active substance of the Chinese herb corydalis which induces hypotension and bradycardia in rats through the antagonism of striatal dopamine D2 receptor.
Usesanalgesic, hypnotic, papaverine-like
UsesDL-Tetrahydropalmatine is the main active substance of the Chinese herb corydalis which induces hypotension and bradycardia in rats through the antagonism of striatal dopamine D2 receptor.
PreparationA. Berberine hydrochloride is ring-opened under the conditions of p-toluenesulfonic acid, xylene, and HCl at 70°C to obtain desmethylene berberine hydrochloride.B. Demethylene berberine hydrochloride is methyl etherified with potassium carbonate, methanol, and dimethyl sulfate at 40°C to obtain palmatine hydrochloride.C. Palmatine hydrochloride is racemized under the conditions of methanol and sodium borohydride to obtain tetrahydropalmatine.
