Tropicamide is an antimuscarinic drug usually prescribed as an ophthalmic solution to induce short-term mydriasis and cycloplegia. Tropicamide is currently abused (injected intravenously) as an inexpensive recreational deliriant drug.
Misuse of tropicamide typically occurs through IV injection; its effects last from 30 min to 6 h, and It is usually mixed with heroin, methadone, and other opioid drugs to potentiate the ” rush” when injected intravenously.Medical effects of tropicamide misuse include slurred speech, persistent mydriasis, unconsciousness/unresponsiveness, hallucinations, kidney pain, dysphoria, “open eye dreams,” hyperthermia, tremors, suicidal feelings, convulsions, psychomotor agitation, tachycardia and headache. The TRO Rapid Test Panel (Urine) is a rapid urine screening test that can be performed without the use of an instrument. The test utilizes a monoclonal antibody to selectively detect elevated levels of tropicamide in urine. The Multi-Drug Rapid Test Panel yields a positive result when the concentration of Tropicamide in urine exceeds detective level.
