Simvastatin is a derivative of lovastatin and potent competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase (hydroxymethylglutaryl COA reductases), which is the rate-limiting enzyme in cholesterol biosynthesis. It may also interfere with steroid hormone production. Due to the induction of hepatic LDL receptors, it increases breakdown of LDL cholesterol. The 6-membered lactone ring of simvastatin is hydrolyzed in vivo to generate mevinolinic acid, an active metabolite structurally similar to HMG-CoA (hydroxymethylglutaryl CoA). Once hydrolyzed, simvastatin competes with HMG-CoA for HMG-CoA reductase, a hepatic microsomal enzyme. Interference with the activity of this enzyme reduces the quantity of mevalonic acid, a precursor of cholesterol.

Spiradoline is a drug which acts as a highly selective κ-opioid agonist. It has analgesic, diuretic and antitussive effects, and produces subjective effects in animals similar to those of ketocyclazocine and allylnormetazocine. The main effect in humans is sedation, along with analgesic and diuretic effects, but significant side effects such as dysphoria and hallucinations have stopped it from being used clinically. Kappa-agonists have been shown to react negatively with the Mu-receptor, instead of having an assumed synergy since they are both opiate receptors, such as with the Mu and Delta receptors.
