The Drug Development Process Explained
The drug development process from laboratory research to patients: translational research, decision gates, who does what, and how a medicine reaches clinical use.
Regulatory approval establishes that a product may be sold. Whether patients can obtain it is a separate decision, taken nationally or locally through reimbursement, health technology assessment and formulary processes — which is why an approved medicine can be unavailable in a country for years, or indefinitely.
This distinction is the one most often lost in coverage of new treatments, and it is the one that determines whether an announcement changes anything for a patient. We report both decisions and keep them apart.

How drug approval works: what regulators assess, how FDA and EMA review differ, expedited pathways, conditional approvals, and what happens after authorisation.
How medical device innovation works: needs identification, prototyping, design controls, risk management, clinical evaluation, regulatory approval and adoption.
Remote patient monitoring explained: devices, clinical uses in heart failure, diabetes and hypertension, evidence, workflow design, reimbursement and risks.
How healthcare regulation works: who regulates professionals, providers, medicines, devices and data, how rules are enforced, and why regulatory systems differ.
FDA and EMA regulatory pathways compared: standard and expedited routes, evidence requirements, decision structures, and why approvals differ between regions.
