The following anaesthetic drug causes pain on intravenous administration

Induction of anesthesia with propofol is often associated with pain on injection, apnea, hypotension, and, rarely, thrombophlebitis of the vein into which propofol is injected. Pain on injection is reduced by using a large vein, avoiding veins in the dorsum of the hand, and adding lidocaine to the propofol solution or changing the propofol formulation. Multiple other drugs and distraction techniques have been investigated to reduce the pain on injection of propofol. Pretreatment with a small dose of propofol, opiates, nonsteroidal antiinflammatory drugs, ketamine, esmolol or metoprolol, magnesium, a flash of light, a clonidine-ephedrine combination, dexamethasone, and metoclopramide all have been tested with variable efficacy.
