Miglitol (Glyset)

Mevastatin (Compactin; ML236B) inhibits HMGCR (HMG-CoA reductase) (Ki for acid form is 1 nM) which in turn inhibits isoprenoid biosynthesis and therefore blocks protein isoprenylation and reduces plasma cholesterol levels in humans.

Metoprolol is a cardioselective β1-adrenergic blocking agent.

Metolazone (Zaroxolyn)

Methylprednisolone

Methoxsalen (Oxsoralen)

Methotrexate(WR19039; CL14377) can interfere with the growth of certain cells of the body, especially cells that reproduce quickly, such as cancer cells, bone marrow cells, and skin cells.

Methocarbamol is a central muscle relaxant used to treat skeletal muscle spasms.

Methimazole(Tapazole, Northyx) is an antithyroid medicine.

Methacycline HCl (Physiomycine)

Metformin HCl(Glucophage)

Mestranol

Meloxicam (Mobic)

Medetomidine hydrochloride is a potent and highly selective α2-AR adrenoceptor agonist (Ki values are 1.08 and 1750 nM for α2- and α1-adrenoceptors respectively). Shows greater selectivity over α1-adrenoceptors than clonidine and UK 14,304 (1620-, 220- an

Meclofenoxate hydrochloride, an ester of dimethylethanolamine (DMAE) and 4-chlorophenoxyacetic acid (pCPA), has been shown to improve memory, have a mentally stimulating effect, and improve general cognition.

Mecarbinate

Malotilate

Lupus erythematosus suppressant as well as an antimalerial and antirheumatic.

L-Thyroxine

Loxoprofen is a non-steroidal anti-inflammatory drug that is quickly converted to the trans-alcohol metabolite. It is similar to ibuprofen and naproxen, while also being a Cycloxygenase (COX) inhibitor.

Loteprednol etabonate

Losartan is a potent, non peptide antagonist of the angiotensin II receptor type 1. This receptor initiates a signal cascade that causes vasoconstriction. Antagonism of this receptor in turn causes vasodilation by blocking the signal from angiotensin II.

Loratadine(SCH-29851) is a selective inverse peripheral histamine H1-receptor agonist with an IC50 of >32 μM.

Loperamide HCl is an opioid-receptor agonist used as long-acting synthetic antidiarrheals.

Lomustine (CeeNU)

Lomerizine dihydrochloride is a relatively new L- and T-type calcium channel blocker used in the treatment of migraine.

Lomefloxacin HCl (Maxaquin)

L-NAME is a nonselective inhibitor of nitric oxide synthetases (NOS) for nNOS (bovine), eNOS (human), and iNOS (murine), with Ki of 15 nM, 39 nM and 4.4 μM, respectively.

Lisinopril Dihydrate is angiotensin-converting enzyme inhibitor, used in treatment of hypertension, congestive heart failure, and heart attacks.

Lincomycin HCl (Lincocin)
