1. The Spectrum Explained Psychotropic drugs interact with receptors along a continuous spectrum: Full Agonist Produces the maximum possible response when it binds to the receptor. Example: Benzodiazepines are full agonists at GABA-A receptors → strong sedation and anxiolysis. Partial Agonist Produces a submaximal response — even at full receptor occupancy. Importantly, partial agonists can […]

1. What is Epigenetics? Epigenetics refers to modifications that control whether genes are turned “on” or “off.” The main mechanisms are: DNA methylation — usually silences genes. Histone modifications (acetylation, methylation) — acetylation generally opens chromatin for gene activation; deacetylation closes it. Non-coding RNAs (like microRNAs) — fine-tune expression. These changes are influenced by environment […]

1. What is CYP450 and Why Should We Care? CYP450 refers to a family of liver enzymes responsible for metabolizing — breaking down — the majority of medications we use in psychiatry. These enzymes perform Phase I metabolism, oxidizing drugs so they can be eliminated from the body. Think of CYP450 as the liver’s “drug […]

1. The Core Principle: Chemical Neurotransmission Everything in psychopharmacology begins with how neurons communicate. Inside a neuron, signals are electrical. Between neurons, they are chemical — at the synapse. An action potential reaches the presynaptic terminal, calcium rushes in, and neurotransmitters are released into the synaptic cleft. These bind to postsynaptic receptors, triggering either excitation […]
