Tilade (nedocromil sodium) is an inhaled anti-inflammatory agent for the preventive
management of asthma. Nedocromil sodium is a pyranoquinoline with the chemical
name 4H-Pyrano[3,2-g]quinoline-2,8-dicarboxylic acid, 9-ethyl-6,9-dihydro-4,6-dioxo-10-propyl-,
disodium salt, and it has a molecular weight of 415.3. The empirical formula
is C19H15NNa2O7. Nedocromil sodium,
a yellow powder, is soluble in water.
The molecular structure of nedocromil sodium is:
Chemical Class: Pyranoquinoline
Tilade Inhaler (nedocromil sodium inhalation aerosol) is a pressurized metered-dose
aerosol suspension for oral inhalation containing micronized nedocromil sodium
and sorbitan trioleate, as well as dichlorotetrafluoroethane and dichlorodifluoromethane
as propellants. Each Tilade canister contains 210 mg nedocromil sodium.
Each actuation meters 2.00 mg nedocromil sodium from the valve and delivers
1.75 mg nedocromil sodium from the mouthpiece. Each 16.2 g canister provides
at least 104 metered actuations. After 104 metered actuations, the amount
delivered per actuation may not be consistent and the unit should be discarded.
Each Tilade (nedocromil inhalation aerosol) Inhaler canister must be primed with 3 actuations prior
to the first use. If a canister remains unused for more than 7 days, then it
should be reprimed with 3 actuations.
