Introduction
Medical documents require precise notation for drugs, dosages, and clinical data. LaTeX provides tools for professional medical publications. From research papers to clinical reports, LaTeX ensures accuracy and consistency in medical documentation.
This guide covers medical document creation in LaTeX, including drug notations, clinical data presentation, and medical formatting standards.
Drug Notations
Chemical Formulas with mhchem
The mhchem package provides chemical equation formatting:
\usepackage{mhchem}
% Molecular formulas
\ce{C9H8O4} % Aspirin
\ce{C13H18O2} % Ibuprofen
\ce{C21H30O2} % Prednisone
% Chemical reactions
\ce{2H2 + O2 -> 2H2O}
% Equilibrium reactions
\ce{HA <=> H+ + A-}
% Isotopic notation
\ce{^{131}_{55}I}
Dosage Formatting with siunitx
\usepackage{siunitx}
% Standard dosages
\SI{500}{\milli\gram} dose
\SI{10}{\milli\gram\per\kilogram}
\SI{5}{\milli\liter}
% Concentrations
\SI{0.9}{\percent} NaCl
\SI{50}{\milli\gram\per\deciliter}
% IV rates
\SI{100}{\milli\liter\per\hour}
\SI{5}{\micro\gram\per\kilogram\per\minute}
Drug Prescription Format
\textit{ibuprofen} \SI{400}{\milli\gram} q6h prn
\textit{lisinopril} \SI{10}{\milli\gram} PO daily
\textit{metformin} \SI{500}{\milli\gram} BID with meals
Clinical Data
Patient Characteristics Tables
\usepackage{booktabs}
\begin{table}[htbp]
\centering
\caption{Patient Characteristics at Baseline}
\begin{tabular}{lccc}
\toprule
\textbf{Characteristic} & \textbf{Treatment} & \textbf{Control} & \textbf{p-value}\\
\midrule
Age (years) & $45 \pm 12$ & $47 \pm 11$ & 0.34\\
Male n (\%) & 45 (60\%) & 42 (56\%) & 0.52\\
BMI (kg/m²) & $28.4 \pm 4.2$ & $27.9 \pm 3.8$ & 0.41\\
SBP (mmHg) & $132 \pm 15$ & $135 \pm 14$ & 0.18\\
\bottomrule
\end{tabular}
\end{table}
Laboratory Values
\begin{table}
\centering
\caption{Laboratory Results}
\begin{tabular}{lS[table-format=3.1]S[table-format=3.1]s[table-format=1.2]}
\toprule
\textbf{Test} & \textbf{Patient} & \textbf{Reference} & \textbf{Unit}\\
\midrule
Glucose & 105 & 70-100 & mg/dL\\
Creatinine & 1.2 & 0.7-1.3 & mg/dL\\
Hemoglobin & 14.5 & 12.0-17.5 & g/dL\\
\bottomrule
\end{tabular}
\end{table}
Medical References
Vancouver Style
The Vancouver system uses numbered references:
\begin{thebibliography}{99}
\bibitem{smith2023}
Smith J, Johnson A. Treatment outcomes in clinical trials.
\textit{J Med Pract}. 2023;45(2):123-130.
\bibitem{who2024}
World Health Organization. Guidelines for hypertension
management. \textit{WHO Guidelines}. 2024.
\end{thebibliography}
APA Style for Medical Papers
\usepackage{apacite}
\bibliography{medical_references}
% In-text citations
\cite{smith2023} found significant improvements...
\citeA{johnson2022} demonstrated...
Anatomical Notation
Anatomical Directions
% Superior/Inferior
\text superior (above)
\text inferior (below)
% Anterior/Posterior
\text anterior (front)
\text posterior (back)
% Lateral/Medial
\text lateral (side)
\text medial (middle)
% Proximal/Distal
\text proximal (nearer to trunk)
\text distal (farther from trunk)
Body Positions
% Anatomical position reference
\text{Patient is in prone position (lying face down)}
\text{Lesion is located on the dorsal surface}
\text{The distal phalanx is affected}
Medical Graphics
TikZ for Anatomical Diagrams
\usepackage{tikz}
\begin{tikzpicture}
% Simple anatomical representation
\draw (0,0) ellipse (1 and 2);
\draw (0,0) -- (1,-1);
\draw (0,0) -- (-1,-1);
\node at (0,2) {Head};
\end{tikzpicture}
Clinical Trial Documentation
CONSORT Flow Diagram Elements
\documentclass[tikz]{standalone}
\usepackage{booktabs}
\begin{tikzpicture}[node distance=2cm]
\node (enrollment) [rectangle, draw] {Enrollment};
\node (allocation) [rectangle, draw, right=of enrollment] {Allocation};
\node (followup) [rectangle, draw, right=of allocation] {Follow-Up};
\node (analysis) [rectangle, draw, right=of followup] {Analysis};

Drug Interaction Tables
\begin{table}
\centering
\caption{Drug Interactions}
\begin{tabular}{lll}
\toprule
\textbf{Drug A} & \textbf{Drug B} & \textbf{Effect}\\
\midrule
