Corticosteroid inhaler for asthma

QNASL Nasal Aerosol is a pressurized, nonaqueous solution in a metered-dose aerosol device intended ONLY for intranasal use. It contains a solution of beclomethasone dipropionate in propellant HFA-134a (1,1,1,2-tetrafluoroethane) and dehydrated ethanol. QNASL 40 mcg Nasal Aerosol delivers 40 mcg of beclomethasone dipropionate from the nasal actuator and 50 mcg from the valve. QNASL 80 mcg Nasal Aerosol delivers 80 mcg of beclomethasone dipropionate from the nasal actuator and 100 mcg from the valve. Each strength delivers 59 mg of solution from the valve with each actuation. Each canister of QNASL 40 mcg or 80 mcg Nasal Aerosol, contains  g of drug and excipients and each provides 120 actuations after priming. Additionally, QNASL 40 mcg Nasal Aerosol contains g of drug and excipients and provides 60 actuations after priming.

Use of QVAR with a spacer device in children less than 5 years of age is not recommended. In vitro dose characterization studies were performed with QVAR 40 mcg/actuation with the OptiChamber and AeroChamber Plus ® spacer utilizing inspiratory flows representative of children under 5 years old. These studies indicated that the amount of medication delivered through the spacing device decreased rapidly with increasing wait times of 5 to 10 seconds as shown in Table 2. If QVAR is used with a spacer device, it is important to inhale immediately.

Do not use for an acute asthma attack . Inhaled corticosteroids work to slowly decrease airway inflammation and usually are of limited benefit during an acute attack of asthma. That is why these medications are maintenance or controller medication. They are not intended for use to treat an acute attack. Inhaled corticosteroids may decrease growth in children, so use the lowest dose possible. Inhaled corticosteroids may also increase the risk of serious or fatal infection in individuals exposed to serious viral infections like chickenpox or measles . Long-term use may cause cataracts or glaucoma (increased pressure within the eyes). These medications may increase the risk of pneumonia .
