Solovent
Solovent Uses, Dosage, Side Effects, Food Interaction and all others data.
Solovent stimulates intracellular adenyl cyclase, the enzyme that catalyses the conversion of ATP to cyclic-3',5'-adenosine monophosphate (cAMP) resulting in relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from mast cells.
Solovent is a long acting beta-2 adrenergic receptor agonist that binds to both the active and exo sites of the beta-2 adrenergic receptor. Solovent has a longer duration of action than other beta-2 agonists like salbutamol. Patients should be counselled regarding the risks of long acting beta agonist (LABA) monotherapy, hypokalemia, hypoglycemia, and not to take this drug with another LABA.

Uses
Inhaled Solovent exerts a significant bronchodilating effect within 10 to 20 minutes of single-dose administration with asthma and this effect lasts for up to 12 hours or more. Solovent has a beneficial effect on airway mucociliary clearance that will reduce the incidence of respiratory tract infections.
Solovent produces a significant protective effect against Exercise Induced Asthma (EIA) for up to 9 to 12 hours in both adolescents and adults.
Solovent improves the overnight PEFR (Peak Expiratory Flow Rate) and controls the symptoms of the patients with nocturnal asthma. The use of Solovent avoids exposure of children to theophylline or high-dose corticosteroid, with their attendants risks.
Addition of Solovent to inhaled corticosteroid therapy is significantly more effective in terms of an improvement in lung function, symptom control and a reduction in the use of rescue bronchodilator therapy (use of short acting beta2-agonist).
Addition of Solovent to inhaled corticosteroid therapy also significantly reduces the use of inhaled corticosteroids
Solovent is also used to associated treatment for these conditions: Asthma, Chronic Obstructive Pulmonary Disease (COPD), Exercise-Induced Bronchospasm
How Solovent works
Beta-2 adrenoceptor stimulation causes relaxation of bronchial smooth muscle, bronchodilation, and increased airflow.
Solovent is hypothesized to bind to 2 sites on the beta-2 adrenoceptor. The saligenin moiety binds to the active site of the beta-2 adrenoceptor. The hydrophilic tail of salmeterol binds to leucine residues in the exo-site of the beta-2 adrenoceptor almost irreversibly, allowing salmeterol to persist in the active site, which is responsible for it's long duration of action.
Another hypothesis is that the lipophilic drug diffuses into lipid bilayer of smooth muscle cells and provides a depot of drug to the cells over a longer period of time.
Dosage
Solovent dosage
Inhalation/Respiratory-
Chronic asthma:
- Adult: As metered dose aerosol or dry powder inhaler: 50 mcg bid, or up to 100 mcg bid if necessary, in asthma patients with more severe airways obstruction.
- Child: 4-12 yr 50 mcg bid.
Prophylaxis of exercise-induced asthma:
- Adult: As metered dose aerosol or dry powd inhaler: 50 mcg at least 30 min prior to exercise.
- Child: ≥4 yr Same as adult dose.
Chronic obstructive pulmonary disease:
- Adult: As metered dose aerosol or dry powder inhaler: 50 mcg bid.
Side Effects
Dose related tremor, subjective palpitations and headaches are usually mild and transient. Skin reactions, muscle cramps, non-specific chest pain, local irritation and arthralgia have been reported.
Toxicity
Patients experiencing an overdose have presented with metabolic acidosis, hyperlactatemia, anxiety, palpitations, chest pain, sinus tachycardia, ST depression, hypokalemia, hypophosphatemia. Though patients may also present with seizures, angina, hypertension or hypotension, arrhythmia, headache, tremor, muscle cramps, dry mouth, nausea, dizziness, fatigue, malaise, insomnia, and hyperglycemia. Patients should be given symptomatic and supportive treatment which may include intravenous fluids, potassium supplementation, a cardioselective beta-blocker, and cardiac monitoring.
Data regarding the LD50 of salmeterol is not readily available.
Precaution
Patient with CV disease, CNS disorders, DM, hyperthyroidism, hypokalaemia, seizure disorders, ketoacidosis. Not intended for the relief of acute bronchospasm. Hepatic impairment. Pregnancy and lactation.
Interaction
As with all the other beta2-agonists there may be interaction with betablocking agents at the receptor site when given concomitantly.
Monoamino Oxidase Inhibitors and Tricyclic Antidepressants : These agent should be used with caution because Solovent may be potentiated by these agents.
Food Interaction
No interactions found.Solovent Hypertension interaction
[Moderate] Adrenergic bronchodilators can stimulate cardiovascular beta- 1 and beta- 2 receptors, resulting in adverse effects such as tachycardia, palpitation, peripheral vasodilation, blood pressure changes, and ECG changes (e.g., flattening of the T wave; prolongation of the QT interval; ST segment depression).
Direct stimulation of cardiac tissues is mediated by beta- 1 receptors and thus less likely to occur with beta-2-selective agents such as albuterol.
However, beta-2-selectivity is not absolute and can be lost with larger doses.
High dosages of these agents have been associated with precipitation or aggravation of angina, myocardial ischemia, and cardiac arrhythmias.
Therapy with adrenergic bronchodilators should be administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, and The recommended dosages should not be exceeded.
