ARECOLINE

 ARECOLINE


BRAND NAME:-  no specific brand available 



ARECOLINE is an alkaloid obtained from betel nut areca catechu and has muscarinic as well as nicotinic actions, including those on skeletal muscle endplate. It also has prominent CNS effect: has been tried in dementia as an enhancer of cognitive function, but not found useful — has no therapeutic use.



PHARMACOLOGICALLY:-

Arecoline is the primary active ingredient responsible for the central nervous system effects of the areca nut. Arecoline has been compared to nicotine; however, nicotine agonizes nicotinic acetylcholine receptors, whereas arecoline is primarily a partial agonist of muscarinic acetylcholine receptors,leading to its parasympathetic effects. In frogs, arecoline also acts as an antagonist (or very weak partial agonist) at α4 and α6-containing nicotinic acetylcholine receptors and as a silent antagonist at α7 nicotinic receptors, which may account for its anti-inflammatory activity.Arecoline also inhibits AMPK through generation of ROS in several types of cells.


MECHANISM OF ACTION:-

Arecoline could stimulate muscarinic receptor (M receptor) to promote body excitability and improve the abilities of learning and memory. According to popular tradition, the crushed areca nuts (AN) are commonly mixed with lime and enveloped in leaves of Piper betle for chewing .

Betel nut can act on the nervous system and has the effects of antiaging, improving learning and memory. Arecoline has an acetylcholine-like effect, which can activate M receptors, thus stimulating the parasympathetic nerves .


USED:- 

• Its muscarinic and nicotinic agonist properties, arecoline has shown improvement in the learning ability of healthy volunteers.

•Arecoline has also been used medicinally as an antihelmintic (a drug against parasitic worms)

•Arecoline has also been shown to increase testosterone in rats, in low doses. 

•Alzheimer's patients.


SIDE EFFECTS:-

The systemic effects of areca nut are mainly due to the principle alkaloid arecoline. Areca nut causes euphoria, increase in heart rate, increased blood pressure, GABA inhibition and damage to neurons, but has no effect on concentration and memory.

BOTULINUM TOXIN Uses, Side Effects, and More

 BOTULINUM TOXIN ( A or B ) BRAND NAME:- BOTOX ,DYSPORT  BOTULINUM TOXIN  A and B are highly potent exotoxins produced by Clostridium botulinum that are responsible for ' botulism' ( a type of food poisoning). These neurotoxic proteins cause long- lasting loss of cholinergic transmission by interacting with axonal proteins involved in exocytotic release of Ach. Localized injection of minute quantity of botulinum toxin.  PHARMACODYNAMIC :- Botulinum toxin A inhibits the release of acetylcholine, relieving muscle contraction and spasm associated with many conditions, such as incontinence and dystonia. Cosmetically, botulinum toxin A paralyses muscles in the face to temporarily treat wrinkles. The maximum effects of muscle paralysis occur four to seven days after a dose.When injected at therapeutic doses, botulinum toxin A causes partial chemical denervation of muscle tissue, causing local reduction of muscle activity. Muscle atrophy may result, axonal sprouting may beg...

Clonazepam used, Side effects, Dose, & more

Clonazepam  Brand name:- Lonazepam , Clonapax , Rivotril 0.5, 1.0, 2.0 mg tab. Clonazepam is a benzodiazepine. It works by increasing the action of a chemical messenger (GABA) which suppresses the abnormal and excessive activity of the nerve cells in the brain. Pharmacodynamic:- The pharmacodynamic properties of clonazepam are common among benzodiazepines and include anticonvulsive, sedative, muscle relaxing and anxiolytic effects . Animal data and electroencephalographic investigations in man have shown that clonazepam rapidly suppresses many types of paroxysmal activity including the spike and wave discharge in absence seizures (petit mal), slow spike wave, generalized spike wave, spikes with temporal or other locations, as well as irregular spikes and waves Label . Moreover, the agent can also decrease the frequency, amplitude, duration, and spread of discharge in minor motor seizures Label . Generalized EEG abnormalities are more readily suppressed by clonazepam than are focal ...

CLOMIPHENE CITRATE Uses, Side Effects, and More

 CLOMIPHENE CITRATE BRAND NAME:- CLOMIPHENE, FERTOMED, CLOFERT, CLOME 25,50,100mg tab.  Clomiphene is a selective estrogen receptor modulator (SERM) which treats female infertility. It works by promoting the release of reproductive hormones. This helps stimulate the release of eggs from the ovary (ovulation). PHARMACODYANIMCS:- Clomifene (previously clomiphene) is an orally administered, non steroidal, ovulatory stimulant that acts as a selective estrogen receptor modulator (SERM). Clomifene can lead to multiple ovulation, and hence increase the risk of conceiving twins. In comparison to purified FSH, the rate of ovarian hyperstimulation syndrome is low. There may be an increased risk of ovarian cancer and weight gain. Clomifene is capable of interacting with estrogen-receptor-containing tissues, including the hypothalamus, pituitary, ovary, endometrium, vagina, and cervix. It may compete with estrogen for estrogen-receptor-binding sites and may delay replenishment of intracel...
