Answer 2

Safer curare detivatives such as rocuronium and pancuronium have superseded d-tubocurarine used for relaxation effect and even have its usage for anasthesia during surgery.

When used with halothene d-tubocurarine can cause profound fall in blood pressure.

Traditionaly it was sunjected to patients with blow-gun darts.

But nowdays the primitive way is substituted with the usage of ether which is more safe for medical practice.
