<p>As long-term clinical studies have demonstrated, tulobuterol continues to be efficacious and does not result in cumulative or toxic side effects. Due to the variability of the disease and the need for individualized dosage requirements, flexibility in dosing is indispensable.<br />
<br />
The use of Long-Acting Beta Agonists is contraindicated without the use of an asthma controller medication such as inhaled corticosteroid.<br />
<br />
Long-Acting Beta Agonists should be used for the shortest duration of time required to achieve control of asthma symptoms and discontinued, if possible, once asthma control is achieved. Patient should then be maintained on a long-term asthma controller medication (e.g. Corticosteroids).<br />
<br />
<strong>Tablets</strong>: The usual oral adult dose of tulobuterol is one 2 mg tablet twice a day. A convenient starting dose for children 12 years and over and adults is 1 mg twice a day, particularly for elderly patients and those with a history of sensitivity to beta-adrenergic agents. Unless precluded by drug-related side effects, the patient may have the dose increased after seven to ten days to 2 mg twice a day, if necessary, to achieve a greater therapeutic response.<br />
<br />
Although most patients can be maintained on a dose of 1 to 2 mg twice daily, the variability of patient response and severity of symptoms may require further adjustment of the dose, as with any bronchodilator treatment. Therefore, if necessary, the adult dose of tulobuterol may be increased to 6 mg a day in divided doses according to clinical response.<br />
<br />
<strong>Syrup</strong>: Based on dose-ranging studies in children, the usual dose of tulobuterol syrup (1 mg/5 mL) for children is 40 to 80 mcg/kg/day in two divided doses.<br />
<br />
In clinical studies in children, the effective dose has ranged from 20 to 100 mcg/kg/day.<br />
<br />
This leads to the following recommendations on the basis of age:</p>

<ul>
	<li>For children aged one to six years, 0.25 tsp. (1.25 mL) to 0.5 tsp. (2.5 mL) BID</li>
	<li>For children aged six to twelve years, 0.5 tsp. (2.5 mL) to 1 tsp. (5 mL) BID</li>
	<li>For children aged over twelve years, 1 tsp. (5 mL) to 2 tsp. (10 mL) BID</li>
	<li>The above age recommended doses may have to be modified according to patient response.</li>
</ul>
