Topeka (AP) — First responders and bystanders in Kansas will soon be able to administer life-saving drugs that stop the effects of opioid drug overdoses.

Gov. Sam Brownback signed a bill Friday allowing first responders to administer drugs like naloxone, called “opioid antagonists.” The drugs stop fatal symptoms of prescription drug and heroin overdoses. The law also allows pharmacists to give people the drug without a prescription.

The Legislature passed the measure unanimously. Forty-seven other states have similar laws to help combat a national addiction crisis.

Kansas hasn’t seen the spike in deaths some other states have, but the health department says prescription overdoses rose 28 percent between 2013 and 2015.

Brownback says the law is a “good step toward saving lives in Kansas.”
