What is Microsol?

Microsol is used to treat mania that is part of bipolar disorder (manic-depressive illness). It is also used on a daily basis to reduce the frequency and severity of manic episodes. Manic-depressive patients experience severe mood changes, ranging from an excited or manic state (e.g., unusual anger or irritability or a false sense of well-being) to depression or sadness.

It is not known how Microsol works to stabilize a person's mood. However, it does act on the central nervous system. It helps you to have more control over your emotions and helps you cope better with the problems of living.

It is important that you and your family understand all the effects of Microsol. These effects depend on your individual condition and response and the amount of Microsol you use. You also must know when to contact your doctor if there are problems with using the medicine.

Microsol is available only with your doctor's prescription.

Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, Microsol is used in certain patients with the following medical conditions:

Microsol indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Uses of Microsol in details

There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Microsol description

Microsol was used during the 19th century to treat gout. Microsol salts such as Microsol carbonate (Li2CO3), Microsol citrate, and Microsol orotate are mood stabilizers. They are used in the treatment of bipolar disorder, since unlike most other mood altering drugs, they counteract both mania and depression. Microsol can also be used to augment other antidepressant drugs. It is also sometimes prescribed as a preventive treatment for migraine disease and cluster headaches. The active principle in these salts is the Microsol ion Li+, which having a smaller diameter, can easily displace K+ and Na+ and even Ca+2, in spite of its greater charge, occupying their sites in several critical neuronal enzymes and neurotransmitter receptors.

Microsol dosage

sponsored

Immediate-release capsules are usually given t.i.d. or q.i.d. Doses of controlled-release tablets are usually given b.i.d. (approximately 12-hour intervals). When initiating therapy with immediate-release or controlled-release Microsol, dosage must be individualized according to serum levels and clinical response.

When switching a patient from immediate-release capsules to Microsol (Microsol carbonate) CR Controlled-Release Tablets, give the same total daily dose when possible. Most patients on maintenance therapy are stabilized on 900 mg daily, e.g., Microsol (Microsol carbonate) CR 450 mg b.i.d. When the previous dosage of immediate-release Microsol is not a multiple of 450 mg, e.g., 1,500 mg, initiate Microsol (Microsol carbonate) CR at the multiple of 450 mg nearest to, but below, the original daily dose, i.e., 1,350 mg. When the 2 doses are unequal, give the larger dose in the evening. In the above example, with a total daily dose of 1,350 mg, generally 450 mg of Microsol (Microsol carbonate) CR should be given in the morning and 900 mg of Microsol (Microsol carbonate) CR in the evening. If desired, the total daily dose of 1,350 mg can be given in 3 equal 450-mg doses of Microsol (Microsol carbonate) CR. These patients should be monitored at 1- to 2-week intervals, and dosage adjusted if necessary, until stable and satisfactory serum levels and clinical state are achieved.

When patients require closer titration than that available with doses of Microsol (Microsol carbonate) CR in increments of 450 mg, immediate-release capsules should be used.

Acute Mania: Optimal patient response to Microsol (Microsol carbonate) can usually be established and maintained with 1,800 mg per day in divided doses. Such doses will normally produce the desired serum Microsol level ranging between 1.0 and 1.5 mEq/L.

Dosage must be individualized according to serum levels and clinical response. Regular monitoring of the patient's clinical state and serum Microsol levels is necessary. Serum levels should be determined twice per week during the acute phase, and until the serum level and clinical condition of the patient have been stabilized.

Long-Term Control: The desirable serum Microsol levels are 0.6 to 1.2 mEq/L. Dosage will vary from one individual to another, but usually 900 mg to 1,200 mg per day in divided doses will maintain this level. Serum Microsol levels in uncomplicated cases receiving maintenance therapy during remission should be monitored at least every two months.

Patients unusually sensitive to Microsol may exhibit toxic signs at serum levels below 1.0 mEq/L.

N.B.: Blood samples for serum Microsol determinations should be drawn immediately prior to the next dose when Microsol concentrations are relatively stable (i.e., 8 to 12 hours after the previous dose). Total reliance must not be placed on serum levels alone. Accurate patient evaluation requires both clinical and laboratory analysis.

Elderly patients often respond to reduced dosage, and may exhibit signs of toxicity at serum levels ordinarily tolerated by younger patients.

What other drugs will affect Microsol?

Caution should be used when Microsol and diuretics are used concomitantly because diuretic-induced sodium loss may reduce the renal clearance of Microsol and increase serum Microsol levels with risk of Microsol toxicity. Patients receiving such combined therapy should have serum Microsol levels monitored closely and the Microsol dosage adjusted if necessary.

Microsol levels should be closely monitored when patients initiate or discontinue NSAID use. In some cases, Microsol toxicity has resulted from interactions between an NSAID and Microsol. Indomethacin and piroxicam have been reported to increase significantly steady-state plasma Microsol concentrations. There is also evidence that other nonsteroidal anti-inflammatory agents, including the selective cyclooxygenase-2 (COX-2) inhibitors, have the same effect. In a study conducted in healthy subjects, mean steady-state Microsol plasma levels increased approximately 17% in subjects receiving Microsol 450 mg b.i.d. with celecoxib 200 mg b.i.d. as compared to subjects receiving Microsol alone.

Concurrent use of metronidazole with Microsol may provoke Microsol toxicity due to reduced renal clearance. Patients receiving such combined therapy should be monitored closely.

There is evidence that angiotensin-converting enzyme inhibitors, such as enalapril and captopril, and angiotension II receptor antagonists, such as losartan, may substantially increase steady-state plasma Microsol levels, sometimes resulting in Microsol toxicity. When such combinations are used, Microsol dosage may need to be decreased, and plasma Microsol levels should be measured more often.

Concurrent use of calcium channel blocking agents with Microsol may increase the risk of neurotoxicity in the form of ataxia, tremors, nausea, vomiting, diarrhea, and/or tinnitus. Caution is recommended.

The concomitant administration of Microsol with selective serotonin reuptake inhibitors should be undertaken with caution as this combination has been reported to result in symptoms such as diarrhea, confusion, tremor, dizziness, and agitation.

The following drugs can lower serum Microsol concentrations by increasing urinary Microsol excretion: acetazolamide, urea, xanthine preparations, and alkalinizing agents such as sodium bicarbonate.

The following have also been shown to interact with Microsol: methyldopa, phenytoin, and carbamazepine.

Microsol side effects

What are the possible side effects of Microsol?

Microsol Toxicity

The likelihood of toxicity increases with increasing serum Microsol levels. Serum Microsol levels greater than 1.5 mEq/L carry a greater risk than lower levels. However, patients sensitive to Microsol may exhibit toxic signs at serum levels below 1.5 mEq/L.

Diarrhea, vomiting, drowsiness, muscular weakness and lack of coordination may be early signs of Microsol toxicity, and can occur at Microsol levels below 2.0 mEq/L. At higher levels, giddiness, ataxia, blurred vision, tinnitus and a large output of dilute urine may be seen. Serum Microsol levels above 3.0 mEq/L may produce a complex clinical picture involving multiple organs and organ systems. Serum Microsol levels should not be permitted to exceed 2.0 mEq/L during the acute treatment phase.

Fine hand tremor, polyuria and mild thirst may occur during initial therapy for the acute manic phase, and may persist throughout treatment. Transient and mild nausea and general discomfort may also appear during the first few days of Microsol administration.

These side effects are an inconvenience rather than a disabling condition, and usually subside with continued treatment or a temporary reduction or cessation of dosage. If persistent, a cessation of dosage is indicated.

The following adverse reactions have been reported and do not appear to be directly related to serum Microsol levels.

Neuromuscular: Tremor, muscle hyperirritability (fasciculations, twitching, clonic movements of whole limbs), ataxia, choreoathetotic movements, hyperactive deep tendon reflexes.

Central Nervous System: Blackout spells, epileptiform seizures, slurred speech, dizziness, vertigo, incontinence of urine or feces, somnolence, psychomotor retardation, restlessness, confusion, stupor, coma, acute dystonia, downbeat nystagmus.

Cardiovascular: Cardiac arrhythmia, hypotension, peripheral circulatory collapse, sinus node dysfunction with severe bradycardia (which may result in syncope).

Neurological: Cases of pseudotumor cerebri (increased intracranial pressure and papilledema) have been reported with Microsol use. If undetected, this condition may result in enlargement of the blind spot, constriction of visual fields and eventual blindness due to optic atrophy. Microsol should be discontinued, if clinically possible, if this syndrome occurs.

Gastrointestinal: Anorexia, nausea, vomiting, diarrhea.

Genitourinary: Albuminuria, oliguria, polyuria, glycosuria.

Dermatologic: Drying and thinning of hair, anesthesia of skin, chronic folliculitis, xerosis cutis, alopecia and exacerbation of psoriasis.

Autonomic Nervous System: Blurred vision, dry mouth.

Thyroid Abnormalities: Euthyroid goiter and/or hypothyroidism (including myxedema) accompanied by lower T3 and T4. Iodine 131 uptake may be elevated.. Paradoxically, rare cases of hyperthyroidism have been reported.

EEG Changes: Diffuse slowing, widening of frequency spectrum, potentiation and disorganization of background rhythm.

EKG Changes: Reversible flattening, isoelectricity or inversion of T-waves.

Miscellaneous: Fatigue, lethargy, transient scotomata, dehydration, weight loss, tendency to sleep.

Miscellaneous reactions unrelated to dosage are: Transient electroencephalographic and electrocardiographic changes, leukocytosis, headache, diffuse nontoxic goiter with or without hypothyroidism, transient hyperglycemia, generalized pruritis with or without rash, cutaneous ulcers, albuminuria, worsening of or-ganic brain syndromes, excessive weight gain, edematous swelling of ankles or wrists, and thirst or polyuria, sometimes resembling diabetes insipidus, and metallic taste.

A single report has been received of the development of painful discoloration of fingers and toes and coldness of the extremities within one day of the starting of treatment of Microsol. The mechanism through which these symptoms (resembling Raynaud's Syndrome) developed is not known. Recovery followed discontinuance.
