Diflunisal is a generic NSAID (non-steroidal anti-inflammatory drug). It is often used under the brand name Dolobid marketed by Merck & Co. Diflunisal acts by inhibiting the production of prostaglandin, a hormone that creates inflammation and stimulates the neuro receptors for pain. Though diflunisal has an onset of 1 hour, and maximum analgesia at 2 to 3 hours, the diflunisal plasma levels will not be steady until repeated doesages are achieved. To increase the rate at which the diflunisal plasma levels become steady, a loading dose is usually used. It is primarily used to treat symptoms of arthritis.
[edit] Overdose
Deaths that have occurred from diflunisal usually involved mixed drugs and or extremely high dosages. The oral LD50 is 500 mg/kg. Symptoms of overdose include, coma, tachycardia, stupor, and vomiting. The lowest dose without the presence of other medicines which caused death was 15 grams. Mixed with other medicines, a death at 7.5 grams has also occurred. Diflunisal usually comes in 250 or 500 mg, thus it is relatively hard to overdose by accident.
[edit] Abuse
This medication has no side effects like those of recreational drugs. Therefore it has no chance of misuse.
