I I came across this years ago when doing some research, even though it is about fencamfamine, it would be the closest information pertinant to camfetamine......
from a Formulary of Drugs:
FENCAMFAMIN
Fencamfamin is a central nervous system stimulant whose potency lies midway between that of caffiene and that of amphetamine. The drug is prescribed to relieve lassitude, fatigue and somnolence in the recuperative period following surgical operations or when potent analgesics of the morphine type must be taken regularly: the latter often produce drowsiness at effective dose levels. An extremely useful medicament, fencamfamin is generally well tolerated, and regular use over periods of months does not appear to lead to a significant degree of tolerance, and psychological habituation is not commonly seen. These are possible hazards, as the drug is somewhat euphoriant at doses only slightly in excess of those recommended. Dry mouth, headache, dizziness, abdominal upsets are among the unwanted reactions which have been noted. The compound is not marketed in the USA and the only preparation available in the UK(remember this was when it was available years ago) also contains a number of vitamins of the B group.There seems no reason why fencamfamin should not be tried as an alternative to amphetamines in a number of clinical indications, e.g. narcolepsy. The drug has been prescribed experimentally in cases of dementia: an improvement in alertness and orientation was observed but restlessness occurred in a number of patients. The elderly are in general more susceptible than persons of other age groups to the effects of psychotropic agents.
*10-20 mg. twice or ocasionally three times daily, the last dose taken not later than 4 p.m.: otherwise sleep may be difficult.
*Not recommended in severe hypertension or cardiac disease, hyperthyroidism, glaucoma and states of agitation or hyperexcitability; nor for concurrent use with antidepressants of thr MAO-inhibitor series.
Reactivan(E.Merck) tabs fencamfamin hydrochloride 10 mg, thiamine 10 mg, pyridoxine 20 mg, cyanocobalamin 10 ug, vitamin C 100 mg.
hope this helps .....any older person from UK may remember these....
