Overview
11 DESCRIPTION The active moiety olodaterol is a selective beta 2 -adrenergic bronchodilator. The drug substance, olodaterol hydrochloride, is chemically described as 2H-1,4-Benzoxazin-3H(4H)-one, 6-hydroxy-8-[(1R)-1-hydroxy-2-[[2-(4-methoxyphenyl)-1,1-dimethylethyl]-amino]ethyl]-, monohydrochloride.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Olodaterol is a long-acting beta 2 -adrenergic agonist (LABA). The compound exerts its pharmacological effects by binding and activation of beta 2 -adrenoceptors after topical administration by inhalation. Activation of these receptors in the airways results in a stimulation of intracellular adenyl cyclase, an enzyme that mediates the synthesis of cyclic-3', 5' adenosine monophosphate (cAMP). Elevated levels of cAMP induce bronchodilation by relaxation of airway smooth muscle cells. In vitro studies have shown that olodaterol has 241-fold greater agonist activity at beta 2 -adrenoceptors compared to beta 1 -adrenoceptors and 2,299-fold greater agonist activity compared to beta 3 -adrenoceptors.
Indications
- 1 INDICATIONS AND USAGE STRIVERDI RESPIMAT Inhalation Spray is a long-acting beta 2 -adrenergic agonist (LABA) indicated for: The long-term, once-daily maintenance bronchodilator treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema. ( 1.1 ) Important limitations: STRIVERDI RESPIMAT is NOT indicated to treat acute deterioration of COPD. ( 1.2 ) STRIVERDI RESPIMAT is NOT indicated to treat asthma. ( 1.2 ) 1.
Common Doses
- Refer to label
Dosage
2 DOSAGE AND ADMINISTRATION The recommended dosage of STRIVERDI RESPIMAT is two inhalations once-daily at the same time of the day. Do not use STRIVERDI RESPIMAT more than two inhalations every 24 hours. Prior to first use, the STRIVERDI RESPIMAT cartridge is inserted into the STRIVERDI RESPIMAT inhaler and the unit is primed. When using the unit for the first time, patients are to actuate the inhaler toward the ground until an aerosol cloud is visible and then repeat the process three more times. The unit is then considered primed and ready for use.
Contraindications
- 4 CONTRAINDICATIONS Use of a LABA, including STRIVERDI RESPIMAT, without an inhaled corticosteroid is contraindicated in patients with asthma [see Warnings and Precautions (5.1) ] . STRIVERDI RESPIMAT is not indicated for the treatment of asthma. Use of a LABA, including STRIVERDI RESPIMAT, without an inhaled corticosteroid is contraindicated in patients with asthma. ( 4 )
Side Effects
- 6 ADVERSE REACTIONS Long-acting beta 2 -adrenergic agonists, such as STRIVERDI RESPIMAT, as monotherapy (without an inhaled corticosteroid) for asthma, increase the risk of asthma-related events. STRIVERDI RESPIMAT is not indicated for the treatment of asthma [see Warnings and Precautions (5.1) ] . Most common adverse reactions (incidence ≥2% and more than placebo) are nasopharyngitis, upper respiratory tract infection, bronchitis, urinary tract infection, cough, dizziness, rash, diarrhea, back pain and arthralgia.

Interactions
- 7 DRUG INTERACTIONS Other adrenergic drugs may potentiate effect. Use with caution. ( 5.3 , 7.1 ) Xanthine derivatives, steroids, diuretics or non-potassium sparing diuretics may potentiate hypokalemia or ECG changes. Use with caution. ( 7.2 , 7.3 ) MAO inhibitors, tricyclic antidepressants, and drugs that prolong QTc interval may potentiate effect on cardiovascular system. Use with extreme caution. ( 7.4 ) Beta-blockers may decrease effectiveness. Use with caution and only when medically necessary. ( 7.5 ) 7.
