Katp Channel Openers Inhibit Lymphatic Contractions and Lymph Flow as a Possible Mechanism of Peripheral Edema

Cromakalim relaxes various blood vessels, while minoxidil sulphate is more selective; they likely act on different potassium channels.

This study found that cromakalim and pinacidil significantly inhibited porcine detrusor muscle contractions, suggesting these ATP-sensitive potassium channel openers may have potential in treating certain bladder diseases.

Diazoxide, minoxidil sulphate, and cromakalim relax rat blood vessels by opening K+ channels, with some differences in their actions.

This review discusses the pharmacological properties and therapeutic potential of K+ channel opening compounds, noting their prospective use in treating cardiovascular and respiratory conditions, but reports no new results.

The authors concluded that diazoxide reduces undesirable side effects compared to minoxidil while increasing elastic fiber content and decreasing cell number in the aorta, suggesting potential suitability for treating vascular conditions with low arterial elastin and hypertension.
