Sildenafil, sold under the brand name Viagra, among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension.

Straightforward HPTLC-MS analysis of lactose in dairy products (milk or yoghurt) using only protein crash, centrifugation and dilution as sample preparation.

This paper illustrates the setting up of a Lopinavir assay following European pharmacopoeia guidelines (10.2), and using a shorter column packed with smaller particles. The described assay saves valuable time and improves separation efficiency, which typically translates to better method performance.
