Antihistamines such as pheniramine (PHN) or chlorpheniramine (CPH) are commonly
associated with naphazoline (NPZ) in eye drops and nasal decongestants. In this work, a …

Four accurate and sensitive methods were developed and validated for determination of
naphazoline hydrochloride (NAP) and chlorpheniramine maleate (CLO) in the presence of …

We have developed an optical sensor for determining and quantifying naphazoline (NPZ)
based on its inherent fluorescence property. We have placed a non-ionic-exchanger solid …
