🗑
Synergist   A mutually reinforcing drug interaction such that the joint effect of two drugs administered simultaneously is greater than the sum of their individual effects  
🗑
Systemic effect   affecting the whole body or at least multiple organ systems (contrast with topical or local)  
🗑

🗑
Pharmacokinetics   The process by which a drug is absorbed/distributed/metabolized/eliminated by the body  
🗑

🗑
Agonist   A substance (drug/hormone/neurotransmitter) that binds with a cell receptor to initiate a physiological response  
🗑
Antagonist   a drug that binds to a cellular receptor for a hormone/neurotransmitter/another drug blocking the action of that substance without producing any physiological effect itself
