Is Minocycline legal in the United Kingdom?

No change in mouse survival in either sex in the National Institute on Aging's late-life cohort. In a 412-person ALS trial it made patients worse, and in 544 people with mild Alzheimer's over two years it changed nothing.

Minocycline arrived in ageing research on the strength of a good story. It crosses the blood brain barrier, it suppresses microglial activation, it is anti-apoptotic in vitro, and it extended survival in mouse models of several neurological diseases.

Mechanism: A tetracycline that binds the bacterial 30S ribosomal subunit and blocks aminoacyl-tRNA docking, which is its antibiotic action. Its non-antibiotic properties are the reason it was tested for ageing and neuroprotection: it is lipophilic enough to enter the central nervous system, it inhibits microglial activation and matrix metalloproteinases, and it interferes with caspase-dependent apoptosis and cytochrome c release in cell models.

Regulatory history: Approved as an antibiotic, including for inflammatory acne vulgaris. Not approved for any neurological or ageing indication.

Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.
