MedicationsAluminium hydroxide
As an antacid, aluminium-containing products raise oesophageal pH more than placebo in people with heartburn.

MedicationsAscorbic acid
The evidence is strongest for the one thing the drug is approved for: replacing vitamin C in scurvy.
2026-10-10 · 27 min read
MedicationsBeclomethasone dipropionate
Inhaled beclomethasone is one of the best-tested asthma preventers there is: a Cochrane review of 60 trials in 6542 people found clear improvements in lung function and far fewer trial withdrawals for asthma attacks against placebo, and in people on oral steroids it cut prednisolone use by about 4.91 mg a day.

MedicationsBenzoyl Peroxide
Limited evidence. The evidence that it helps acne is real but weaker than its ubiquity suggests.
2026-10-10 · 23 min read
MedicationsBetamethasone
What is known depends entirely on the route and the condition. The strongest evidence is for a single course injected into a pregnant woman expected to deliver preterm: Cochrane rates it high certainty that this cuts perinatal death, neonatal death and respiratory distress syndrome, with absolute reductions of roughly 2 to 4 percentage points.

MedicationsBrompheniramine; Dextromethorphan; Pseudoephedrine
Limited evidence. Taken as a whole, the evidence is weak and mostly about adults.
2026-10-10 · 31 min read
MedicationsBrompheniramine maleate
The literature on brompheniramine is noticeably thinner than for its siblings, and that thinness is the most honest thing to report about it.
2026-10-10 · 28 min read
MedicationsBuffered aspirin
Well established. Two separate bodies of evidence have to be kept apart here.
2026-10-10 · 40 min read
MedicationsCalcium carbonate
Disputed. Two different jobs with two different evidence bases.
2026-10-10 · 57 min read
MedicationsCamphor
For the topical cough use the human evidence is thin and comes from trials of a combination rub rather than camphor on its own.
2026-10-10 · 26 min read
MedicationsCarbaspirin calcium
Limited evidence. Pharmacologically this is aspirin delivered in a different salt.
2026-10-10 · 26 min read
MedicationsCefuroxime
Well established. The evidence differs sharply between its approved uses.
2026-10-10 · 41 min read
MedicationsChlorhexidine
For the use with the strongest evidence - mouthrinse added to tooth brushing - Cochrane-rated high-quality evidence shows a large reduction in dental plaque.
2026-10-10 · 20 min read
MedicationsChlorpheniramine maleate
For hay fever it does something modest, and the modern placebo-controlled evidence for it is surprisingly scanty for a drug this old.
