Atropine Usage And Synthesis
OverviewAtropine is an alkaloid extracted from the Atropa bell-adonna, Datura stramonium, or Hyosc-yamus niger. What is naturally occurring is the unstable L-hyoscyamine, which can be converted to the stable racemate atropine after chemical treatment. It can also be chemically synthesized; what is commonly used in its sulfate. It appears as white crystalline powder, being odorless, bitter, and soluble in water and alcohol. Upon contact with alkaline drugs, it can cause decomposition. Atropine blocks the M-choline receptor, thereby antagonizing the M-like effect of acetylcholine or its quasi-drug (muscarinic effect).
The main effect is as follows:
  1. Relax the smooth muscle: This product has the role of relaxation of many visceral smooth muscle; it has remarkable relaxation effect on over-activity or spammed smooth muscle, while having less effect on the normal activity of the smooth muscle.
  2. Inhibition of glandular secretion: inhibit the glandular secretion by blocking the M-choline receptor. The most obvious effect occurs on salivary glands and sweat glands. It can also greatly reduce the secretion of lacrimal glands and respiratory glands, but the impact on gastric acid secretion is smaller.
  3. The effect on the eye: atropine, through blocking the pupil sphincter and ciliary muscle M-choline receptors, is manifested as mydriasis, increased intraocular pressure and adjust paralysis. All three effects have important clinical implications.
  4. The effect on the cardiovascular: a larger dose (1 ~ 2mg) atropine can get rid of the inhibitory effect of the vagus nerve on the heart, thus accelerating the heart rate. Large doses can dilate the skin and visceral blood vessels, and relieve arteriolar spasm. Its mechanism of dilating blood vessels and relieving small vasospasm is unknown.
  5. Excitement of the central nervous system: high-dose cause irritability, prolonged talk and delirium. Poisoning dose (more than 10mg) can produce hallucinations, disorientation, involuntary exercise and convulsions.
Chemical propertiesIt appears as white crystalline powder, odorless, tasteless. Mp 114-116°C; sublimation at 93-110 °C under high vacuum. The solubility of this product in each solvent: 80 ℃ hot water (1:90), ethanol (1: 2), chloroform (1: 1), ether (1:25), dissolved in benzene and dilute acid solution. Low toxicity, LD50 (rat, oral): 622mg / kg.
PharmacokineticsIt can be quickly absorbed by the gastrointestinal tract after oral administration and quickly distributed to the body tissue. It can also penetrate through the placenta into the fetal circulation. Clinical studies have shown that after intramuscular injection of 2 mg, 85 ~ 88% is subject to urine excretion within 24 hours. Approximately 5% of them were found in their prototypes and 33% of their metabolites; only a small amount was excreted in feces and other secretions.
Side effectsDry mouth, blurred vision, heart palpitations, dry skin and constipation. High-dose poisoning switches excitement into inhibition, causing coma and respiratory paralysis and death.
ProductionIt can be extracted from the root of Solanaceae Scoparia Anisodus tanguticus or Himalayan Scoparia; can also be obtained by artificial synthesis.
Belladonna leaf is extracted out of the scopolamine (L-body), followed by racemization, recrystallization to make it.
