Chemically, clonazepam is a benzodiazepine derivative. It exhibits several pharmacologic properties, which are characteristics of the benzodiazepine class of drugs. In human it is capable of suppressing the spike and wave discharge in absence seizure (petit mal) and decreasing the frequency, amplitude, duration and spread of discharge in minor motor seizure.

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 . Moreover, the agent can also decrease the frequency, amplitude, duration, and spread of discharge in minor motor seizures .

Generalized EEG abnormalities are more readily suppressed by clonazepam than are focal EEG abnormalities such as focal spikes . Clonazepam has beneficial effects in generalized and focal epilepsies .

Melatonin and melatonin agonists inhibit the release of dopamine from retina through activation of a site that is pharmacologically different from a serotonin receptor. These inhibitory effects are antagonized by the melatonin receptor antagonist luzindole, which suggests that melatonin activates a presynaptic melatonin receptor.

Melatonin is a hormone normally produced in the pineal gland and released into the blood. The essential amino acid L-tryptophan is a precursor in the synthesis of melatonin. It helps regulate sleep-wake cycles or the circadian rhythm. Production of melatonin is stimulated by darkness and inhibited by light. High levels of melatonin induce sleep and so consumption of the drug can be used to combat insomnia and jet lag.MT1 and MT2 receptors may be a target for the treatment of circadian and non circadian sleep disorders because of their differences in pharmacology and function within the SCN. SCN is responsible for maintaining the 24 hour cycle which regulates many different body functions ranging from sleep to immune functions

Melatonin is used for numerous conditions but is showing the most promise in short-term regulation of sleep patterns, including jet lag.

Insomnia: Melatonin helps to induce sleep in people with-

  • Disrupted circadian rhythms (such as those suffering from jet lag or poor vision or those who work the night shift)
  • Low melatonin levels (such as some elderly and individuals with schizophrenia)
  • Children with learning disabilities who suffer from insomnia.

Osteoporosis: Melatonin stimulates cells called osteoblasts that promote bone growth.

In Menopause:

Melatonin helps peri- or postmenopausal women to regulate sleep patterns.

Eating disorders: Melatonin levels may play a role in the symptoms of anorexia.

How Altonil Plus works

Gamma-Aminobutyric acid (GABA) is considered the principal inhibitory neurotransmitter in the human body . When GABA binds to GABA(a) receptors found in neuron synapses, chloride ions are conducted across neuron cell membranes via an ion channel in the receptors . With enough chloride ions conducted, the local, associated neuron membrane potentials are hyperpolarized - making it more difficult or less likely for action potentials to fire, ultimately resulting in less excitation of the neurons .

Subsequently, benzodiazepines like clonazepam can bind to benzodiazepine receptors that are components of various varieties of GABA(a) receptors . This binding acts to enhance the effects of GABA by increasing GABA affinity for the GABA(a) receptor, which ultimately enhances GABA ligand binding at the receptors . This enhanced ligand binding of the inhibitory neurotransmitter GABA to the receptors increases the aforementioned chloride ion conduction (perhaps reportedly via an increase in the frequency of the chloride channel opening), resulting in a hyperpolarized cell membrane that prevents further excitation of the associated neuron cells . Combined with the notion that such benzodiazepine receptor associated GABA(a) receptors exist both peripherally and in the CNS, this activity consequently facilitates various effects like sedation, hypnosis, skeletal muscle relaxation, anticonvulsant activity, and anxiolytic action .

In particular, when out of the ordinary rapid and repetitive electrical signals are released in the CNS, it is proposed that the brain can become over-stimulated and ordinary functions are disrupted - resulting in seizure activity . By enhancing the neuro-inhibitory activity of GABA, it is believed that clonazepam can facilitate in decreasing any excessive electrical nerve activity in the CNS that might be contributing to seizures . Concurrently, it is also believed that clonazepam's actions in enhancing GABA effects may inhibit neuronal activity proposed to occur in amygdala-centered fear circuits - therefore assisting in the management of anxiety or panic .

Melatonin is a derivative of tryptophan. It binds to melatonin receptor type 1A, which then acts on adenylate cylcase and the inhibition of a cAMP signal transduction pathway. Melatonin not only inhibits adenylate cyclase, but it also activates phosphilpase C. This potentiates the release of arachidonate. By binding to melatonin receptors 1 and 2, the downstream signallling cascades have various effects in the body. The melatonin receptors are G protein-coupled receptors and are expressed in various tissues of the body. There are two subtypes of the receptor in humans, melatonin receptor 1 (MT1) and melatonin receptor 2 (MT2). Melatonin and melatonin receptor agonists, on market or in clinical trials, all bind to and activate both receptor types.The binding of the agonists to the receptors has been investigated for over two decades or since 1986. It is somewhat known, but still not fully understood. When melatonin receptor agonists bind to and activate their receptors it causes numerous physiological processes. MT1 receptors are expressed in many regions of the central nervous system (CNS): suprachiasmatic nucleus of the hypothalamus (SNC), hippocampus, substantia nigra, cerebellum, central dopaminergic pathways, ventral tegmental area and nucleus accumbens. MT1 is also expressed in the retina, ovary, testis, mammary gland, coronary circulation and aorta, gallbladder, liver, kidney, skin and the immune system. MT2 receptors are expressed mainly in the CNS, also in the lung, cardiac, coronary and aortic tissue, myometrium and granulosa cells, immune cells, duodenum and adipocytes. The binding of melatonin to melatonin receptors activates a few signaling pathways. MT1 receptor activation inhibits the adenylyl cyclase and its inhibition causes a rippling effect of non activation; starting with decreasing formation of cyclic adenosine monophosphate (cAMP), and then progressing to less protein kinase A (PKA) activity, which in turn hinders the phosphorilation of cAMP responsive element-binding protein (CREB binding protein) into P-CREB. MT1 receptors also activate phospholipase C (PLC), affect ion channels and regulate ion flux inside the cell. The binding of melatonin to MT2 receptors inhibits adenylyl cyclase which decreases the formation of cAMP.[4] As well it hinders guanylyl cyclase and therefore the forming of cyclic guanosine monophosphate (cGMP). Binding to MT2 receptors probably affects PLC which increases protein kinase C (PKC) activity. Activation of the receptor can lead to ion flux inside the cell.

Side Effects

Tablet:

The most frequently occurring side effects of clonazepam are referable to CNS depression, drowsiness, fatigue, dizziness, muscle hypotonia, co-ordination disturbance, hypersalivation in infants, paradoxical aggression, irritability and mental change.

Injection:

Some side effects, like: fatigue, muscle weakness, dizziness, somnolence, light-headedness, ataxia, restlessness, hypersalivation in infants, paradoxical aggression, reduced co-ordination may occur with Clonazepam therapy but these effects are transient and generally disappears in the course of the treatment. Respiratory depression may occur in patients with pre-existing airways obstruction, or brain damage, or if other medications which depress respiration have been given. As a rule, this effect can be avoided by careful adjustment of the dose to individual requirements.

Increased seizure activity; drowsiness, headache. Disruption of normal circadian rhythm. May worsen symptoms for individuals with depression.

Toxicity

Benzodiazepines like clonazepam commonly cause drowsiness, ataxia, dysarthria, and nystagmus. Overdose with clonazepam is generally not life-threatening if the drug is taken alone, but may lead to areflexia, apnea, hypotension, cardiorespiratory depression, and coma. Coma, if it does occur, usually lasts a few hours but it can become more protracted and cyclical, especially in elderly patients. Increased frequency of seizures may occur in patients at supratherapeutic plasma concentrations. Benzodiazepine respiratory depressant effects are more serious when compounded in patients with respiratory disease.

An increased risk of congenital malformations associated with the use of benzodiazepine drugs like clonazepam has been suggested in several studies . There may also be non-teratogenic risks associated with the use of benzodiazepines during pregnancy . There have been reports of neonatal flaccidity, respiratory and feeding difficulties, and hypothermia in children born to mothers who have been receiving benzodiazepines late in pregnancy . In addition, children born to mothers receiving benzodiazepines late in pregnancy may be at some risk of experiencing withdrawal symptoms during the postnatal period . In general, it is best for patients who are of childbearing potential and also use benzodiazepines like clonazepam to discuss such matters with their health care professionals as careful consideration must be undertaken regarding the intersection of the risks of untreated seizure potential in the patient and any possible toxicity to the fetus .

Although the active ingredient of clonazepam has been found to pass into the maternal milk in small amounts only, mothers receiving clonazepam should not breast-feed their infants .

Since the possibility that adverse effects on the physical or mental development of the child could become apparent only after a number of years, the risk-benefit consideration of the long-term use of clonazepam in pediatric patients younger than five years of age is important .

The pharmacological effects of benzodiazepines like clonazepam appear to be greater in elderly patients than in younger patients even at similar plasma benzodiazepine concentrations, possibly because of age-related changes in drug-receptor interactions, post-receptor mechanisms, and organ function . In general elderly patients should be started on the lowest possible dose of clonazepam and observed closely . There is an increased risk for falls and fractures among elderly and debilitated benzodiazepine users . The risk is increased in those taking concomitant sedatives, including substances like benzodiazepines, alcoholic beverages, and so on .

Some oral LD50 values documented are >4000 mg/kg for the mouse model, >4000 mg/kg for the adult rat model, and >2000 mg/kg for the rabbit model .

Generally well-tolerated when taken orally. The most common side effects, day-time drowsiness, headache and dizziness, appear to occur at the same frequency as with placebo. Other reported side effects include transient depressive symptoms, mild tremor, mild anxiety, abdominal cramps, irritability, reduced alertness, confusion, nausea, vomiting, and hypotension. Safety in Adults: Evidence indicates that it is likely safe to use in oral and parenteral forms for up to two months when used appropriately. Some evidence indicates that it can be safely used orally for up to 9 months in some patients. It is also likely safe to use topically when used appropriately. Safety in Children: Melatonin appeared to be used safely in small numbers of children enrolled in short-term clinical trials. However, concerns regarding safety in children have arisen based on their developmental state. Compared to adults over 20 years of age, people under 20 produce high levels of melatonin. Melatonin levels are inversely related to gonadal development and it is thought that exogenous administration of melatonin may adversely affect gonadal development. Safety during Pregnancy: High doses of melatonin administered orally or parenterally may inhibit ovulation. Not advised for use in individuals who are pregnant or trying to become pregnant. Safety during Lactation: Not recommended as safety has not be established.

Oral, rat: LD50 ≥3200 mg/kg

Precaution

Tablet:

When used in patients in whom several different types of seizure disorders coexist, clonazepam may increase the incidence or precipitate the onset of generalized tonic-clonic seizures (grand mal). This may require the addition of appropriate anticonvulsants or an increase in their dosages. The concomitant use of valproic acid and clonazepam may produce absence status. Periodic blood counts and liver function tests are advisable during long term therapy with clonazepam.

The abrupt withdrawal of clonazepam, particularly in those patients on long-term, high-dose therapy, may precipitate status epilepticus. Therefore when discontinuing clonazepam, gradual withdrawal is essential.

Clonazepam may produce an increase in salivation. This should be considered before giving the drug to patients who have difficulty handling secretions. Because of this and the possibility of respiratory depression, clonazepam should be used with caution in patients with chronic respiratory diseases.

Because of the possibility that adverse effects on physical or mental development could become apparent only after many years, a benefit-risk consideration of the long-term use of clonazepam is important in pediatric patients.

Injection:

The concomitant use of Clonazepam with alcohol and CNS depressants should be avoided. Such concomitant use has the potential to increase the clinical effects of Clonazepam, such as: severe sedation, respiratory and cardiac depression. In some cases, dose adjustment of other medications is necessary. Clonazepam may produce an increase in salivation. This should be considered before giving the drug to patients who have difficulty handling secretions. Clonazepam is adviced to use with caution in patients with chronic respiratory diseases. Because of the possibility that adverse effects on physical or mental development could become apparent only after many years, a benefit-risk consideration of the long-term use of clonazepam is important in pediatric patients.

Caffeine and fluvoxamine may increase the effects of melatonin, while melatonin may decrease the antihypertensive effect of nifedipine.

Interaction

Interactions have been reported between some benzodiazepines and other anticonvulsants, with changes in the serum concentration of the benzodiazepine or anticonvulsant.

Antidepressant Medications: Melatonin reduces the antidepressant effects of desipramine and fluoxetine. In addition, fluoxetine leads to measurable depletion of melatonin in people.

Antipsychotic Medications: People with schizophrenia and tardive dyskinesia taking antipsychotic medications with melatonin has significantly reduced mouth movements compared to those who did not take the supplements.

Benzodiazepines: The combination of melatonin and triazolam improves sleep quality. In addition, there have been a few reports suggesting that melatonin supplements may help individuals stop using long-term benzodiazepine therapy.

Blood Pressure Medications: Melatonin may reduce the effectiveness of blood pressure medications like methoxamine and clonidine. In addition, calcium channel blockers (such as nifedipine, verapamil, diltiazem, amlodipine, nimodipine, felodipine, nisoldipine, and bepridil) may decrease melatonin levels. Use of beta-blockers (propranolol, acebutolol, atenolol, labetolol, metoprolol, pindolol, nadolol, sotalol, and timolol) may reduce melatonin production in the body.

Blood-Thinning Medications, Anticoagulants: Melatonin may increase the risk of bleeding from anticoagulant medications such as warfarin.

Interleukin 2: In one study of 80 cancer patients, use of melatonin in conjunction with interleukin-2 led to more tumor regression and better survival rates than treatment with interleukin-2 alone.

Nonsteroidal Anti-inflammatory Drugs (NSAIDs): NSAIDs such as ibuprofen may reduce the levels of melatonin in the blood.

Steroids and Immunosuppressant Medications: People should not take melatonin with corticosteroids or other medications used to suppress the immune system because the supplement may cause them to be ineffective.

Tamoxifen: Preliminary research suggests that the combination of tamoxifen (a chemotherapy drug) and melatonin may benefit certain patients with breast and other cancers.

Other Substances: Caffeine, tobacco, and alcohol can all diminish levels of melatonin in the body while cocaine and amphetamines may increase melatonin production.

Volume of Distribution

Clonazepam distributes very rapidly to various organs and body tissues with preferential uptake by brain structures . The apparent volume of distribution has been documented as approximately 3 L/kg .

Elimination Route

Clonazepam is rapidly and almost entirely absorbed after oral administration as tablets . Peak plasma concentrations of clonazepam administered by the oral route are reached within 1-4 hours and the associated absorption half-life is about 25 minutes . The absolute bioavailability is approximately 90% - but with substantially large differences between individuals .

The absorption and bioavailability of melatonin varies widely.

Half Life

The mean elimination half-life determined for clonazepam is independent of the dose given and has been documented as being about 30-40 hours .

35 to 50 minutes

Clearance

The documented clearance for clonazepam is approximately 55 ml/min regardless of gender . Nevertheless, clearance values normalized by weight decline with increasing body weight .

Elimination Route

Approximately 50-70% of a clonazepam dose is excreted in the urine and 10-30% is excreted in the feces as metabolites . The excretion of unchanged clonazepam in the urine is typically less than 2% of the administered dose . Metabolites of clonazepam are present in urine as both free and conjugated (glucuronide and sulfate) compounds .

Pregnancy & Breastfeeding use

The use of clonazepam during pregnancy or lactation should be avoided. Clonazepam is excreted into the breast milk and should therefore be avoided in breast-feeding mothers.

Information regarding safety and efficacy in pregnancy and lactation is not available.

Contraindication

Clonazepam should not be used in patients with a history of sensitivity to benzodiazepine, nor in patients with clinical or biochemical evidence of significant liver disease. It may be used in patients with open angle glaucoma who are receiving appropriate therapy, but is contraindicated in acute narrow angle glaucoma.

Melatonin should not be used by patients who have autoimmune diseases.

Acute Overdose

Tablet:

Symptoms of clonazepam overdosage, like those produced by other CNS depressants, include somnolence, confusion, coma and diminished reflexes.

Injection:

Symptoms of Clonazepam overdosage, like those produced by other CNS depressants, include: somnolence, confusion, coma and diminished reflexes.

There is little or no evidence of any major toxicities with melatonin, even at high doses.
