Calton (Citalopram)
Calton (Citalopram) Uses, Dosage, Side Effects, Food Interaction and all others data.
Calton (Citalopram) is an orally administered selective serotonin reuptake inhibitor (SSRI) with a chemical structure unrelated to that of other SSRIs, tricyclic, tetracyclic or other available antidepressant agents. The mechanism of action of Calton (Citalopram) as an antidepressant is presumed to be linked to potentiation of serotonergic activity in central nervous system resulting from its inhibition of CNS neuronal reuptake of serotonin (5-HT).
Calton (Citalopram) belongs to a class of antidepressants known as selective serotonin reuptake inhibitors (SSRIs). It has been found to relieve or manage symptoms of depression, anxiety, eating disorders and obsessive-compulsive disorder among other mood disorders. The antidepressant, anti-anxiety, and other actions of citalopram are linked to its inhibition of CNS central uptake of serotonin . Serotonergic abnormalities have been reported in patients with mood disorders. Behavioral and neuropsychological of effects of serotonin include the regulation of mood, perception, reward, anger, aggression, appetite, memory, sexuality, and attention, as examples. The onset of action for depression is approximately 1 to 4 weeks. The complete response may take 8-12 weeks after initiation of citalopram .
In vitro studies demonstrate that citalopram is a strong and selective inhibitor of neuronal serotonin reuptake and has weak effects on norepinephrine and dopamine central reuptake. The chronic administration of citalopram has been shown to downregulate central norepinephrine receptors, similar to other drugs effective in the treatment of major depressive disorder. Calton (Citalopram) does not inhibit monoamine oxidase .

How Calton (Citalopram) works
The mechanism of action of citalopram results from its inhibition of CNS neuronal reuptake of serotonin (5-HT) . The molecular target for citalopram is the serotonin transporter (solute carrier family 6 member 4, SLC6A4), inhibiting its serotonin reuptake in the synaptic cleft .
Calton (Citalopram) binds with significantly less affinity to histamine, acetylcholine, and norepinephrine receptors than tricyclic antidepressant drugs . This drug has no or neglible affinity for 5-HT1A, 5-HT2A, dopamine D1 and D2, α1-, α2-, and_ β adrenergic, _histamine H1, gamma-aminobutyric acid (GABA), muscarinic, cholinergic, and benzodiazepine receptors. Antagonism of muscarinic, histaminergic, and adrenergic receptors is thought to be associated with several anticholinergic, sedative, and cardiovascular effects of other psychotropic drugs .
Dosage
Calton (Citalopram) dosage
Depressive illness 20 mg daily as a single dose in the morning or evening; increased ifnecessary to maximum 60 mg daily (Elderly maximum 40 mgdaily).Panic disorder Initially 10 mg daily, increased to 20 mg after 7 days; usual dose 20-30 mg daily; maximum 60 mg daily (Elderly maximum 40 mgdaily).
Side Effects
SSRIs are less sedating and have fewer antimuscarinic and cardiotoxic effects than tricyclic antidepressants. However, side-effects may be seen, includes gastro-intestinal effects (nausea, vomiting, dyspepsia, abdominal pain, diarrhoea, constipation), anorexia with weight loss, palpitations, tachycardia, postural hypotension, cough, confusion, impaired concentration, amnesia, urinary retention, sweating, movement disorders, urticaria, anaphylaxis, arthralgia, myalgia and photosensitivity.
Toxicity
Oral (Human) LD: 56 mg/kg Intraperitoneal (Mouse) LD50: 179 mg/kg
Acute toxicity
Symptoms of toxicity include dizziness, sweating, nausea, vomiting, tremor, somnolence, and sinus tachycardia. Rarely, symptoms included amnesia, confusion, coma, convulsions, hyperventilation, cyanosis, rhabdomyolysis, and ECG changes (including QTc prolongation, nodal rhythm, ventricular arrhythmia, and extremely rare cases of cardiac torsade de pointes) may occur. Acute renal failure has been a rare occurrence .
In cases of overdose, establish and maintain the airway to ensure adequate ventilation and oxygen delivery. Due to the large volume of distribution of citalopram, forced diuresis, dialysis, hemoperfusion, and exchange transfusion are unlikely to be of benefit. Gastric evacuation by lavage and use of activated charcoal should be considered. Careful observation and cardiac and vital sign monitoring are advised, in addition to supportive care. With the large volume of distribution of citalopram, forced diuresis, dialysis, hemoperfusion, and exchange transfusion are unlikely to be of benefit .
Pregnancy
This drug is categorized as pregnancy category C. In animal reproduction studies, citalopram has been shown to have adverse effects on embryo/fetal and postnatal development, which includes teratogenic effects when given at doses higher than human therapeutic doses. There are no sufficient and well-controlled studies in pregnant women; therefore, citalopram should be used during pregnancy only in cases where the potential benefit justifies the possible risk to the fetus .
Pregnancy-Nonteratogenic Effects
Neonates exposed to celexa and other SSRIs or SNRIs, late in the third trimester, have undergone complications requiring prolonged hospitalization, respiratory support, and parenteral feeding. Complications such as these can arise immediately upon delivery .
Nursing Mothers
Calton (Citalopram) is excreted in human breast milk. There have been two reports of infants demonstrating high levels of somnolence, reduced feeding, and weight loss associated with breastfeeding from a mother taking citalopram. In one specific case, the infant was reported to recover completely after the discontinuation of citalopram. In the second case, no follow-up information was available for assessment. The decision whether to continue or discontinue either nursing or celexa should consider the risks of citalopram exposure for the infant versus the benefits of celexa treatment for the mother .
Precaution
Caution should be taken in patients with epilepsy, concurrent electroconvulsive therapy, history of mania, cardiac disease, diabetes mellitus, angle-closure glaucoma, history of bleeding disorders, hepatic and renal impairment. Abrupt withdrawal of Calton (Citalopram) should be avoided.
Interaction
Ketoconazole, Itraconazole or Macrolide antibiotics and Calton (Citalopram) co-administration decreases the metabolism of Calton (Citalopram). Omeprazole and Calton (Citalopram) co-administration might decrease the clearance of Calton (Citalopram).
Food Interaction
- Avoid alcohol.
- Avoid St. John's Wort.
- Take with or without food. The absorption is unaffected by food.
[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents.
Use in combination may result in additive central nervous system depression and
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol.
Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

The systemic clearance of citalopram is 330 mL/min, with approximately 20% renal clearance .
Elimination Route
12-23% of an oral dose of citalopram is found unchanged in the urine, while 10% of the dose is found in the faeces .
Pregnancy & Breastfeeding use
PregnancyThere are no adequate and well-controlled studies in pregnant women; therefore, Calton (Citalopram) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
LactationCalton (Citalopram) is excreted in human breast milk.
