HB; si+xi) is alwi~~x present for improvement of the symptomat,ic medication of patients. The ideal is therapeutic efficacy without toxicity, undesirable side cfftwts, or acclimation of the patient to the t,hcrapcutic agent. Clinical trial in man is always necessary as animal work is rarely transposable directly and c~t~nlplt+4~-to human beings. Clinical trial without gross bias on the part of eitlscr the t~sperimcntcr or thv subject, is mandatory, although rarely obtainable absolut~cly. No one technique is foolproof in this regard but the randomized tloublc blind tt~chniqno which ntilizes three solutions-a placebo, a standard solution, and the test I,rt’l)aration-tlliinirlatcs positive bias though not nccessarily nt‘gati\rt) hias. Such a schn;~ is superior to the t,wo solution study which wnsists of a standard solution and new test solution but without a placebo. ‘l%ougli there are criticisms both pro and con of patient selection for clinical stlldy, one obviously needs to make srlrctions of test subjects on the basis of Irwd, applicability of type of nlcdic~ation to clinical symptoms, correctness Of clinical diagnosis, and the ability of thr suhjert to discern small differences in tlrc cffwts of diffcrcnt medications.’ Thus patients with a hi~ller-than-average intelligcncc level were chosen from a private allerg l)racticc. Automatic cooperation was assured that all starting the study would cornplt~te it. Their symptoms consisted primarily of ll;lsal l~lockagc dnc to allergic* rhinitis, bccnnse nose drops or sprays arc most of~wtivt~ in this group. Haviny iwd many local nasal preparations over a Iwriotl of >-claw, thtw patients had a firm foundation for reporting comparison clata accuratcl;\-. A publication of the H. T. F. Research Foundation made possible through the gracious mowration of John T. Groel, M.D., Squibb Institute of Medical Research, New Brunswick, S. J.

No definitive studies in man have ever been performed on the extent or rate of absorption of nasal medication from the nasal mucosa in its normal, inflamed, or allergic edema states. This lack exists because of the inability to use physiologic indicators that can be accurutc~ly quantitated in the laboratory. Studies on 3 patients with forced usage of up to 20 cc. in 11 days (0.03 mg. per day) of triamcinolone acctonide produced no changes in glucose tolerance or plasma, 17-h~-droxycortic~oste~~or~~~ lcvcls as was to bcr esp~~ctrtl.

Three coded nasal sprays in identical plastic squeeze: bottles, labeled ;I, K, and C, were used. The identit>- of their contents were withheld from the: author until the completion of the study. The bottles were given out, in consecutive weeks in a randomized manner so that 3 weeks wc~‘e recluired to study all three solutions in any one patient. The data WI results were recorded at weekly intervals. C’ritcbria of recording results were no relief, some relief (but incomplete), and complete relict of b1ock;lgi.c with rcWrn of t,he olfactory sense. Thirty subjects were studied from February to June, 1960, inclusive. There were 16 males from 9 to 53 years of age and 1-C females aged from 4 to 68 years. All subjects were not studied simult;rneonsl~- so that two separate but blended pollen seasons were included in the st,udy. KESULTS

Solution A contained phenylephrine 0.5 per cent, neomycin sulfate 0.5 prr cent (equivalent to 0.35 per cent neomycin base) and gramicidin 0.005 per cent; solution B contained phenylephrine 0.5 per cent, neomJ-tin sulfate 0.5 per cent, gramicidin 0.005 per cent, and triamcinolone acetonide 0.0167 per cent; and SO~Ution C was the placebo vehicle. As can be seen from Table I, solution A of phenylephrine, neomycin, and gramicidin gave excellent results in 3 patients, some effect in 17, and no therapeutic action in 10. Solution B of phcnylcphrine, mlomycin, gramicidin, and triamcinolone acetonide gave excellent relief in 19, some relief in 9, and was a failure in 2; solution C of the placebo vehicle gave excellent relief in none, some relief in none, and no effects in 30. The advantages of three solutions over a two-solution study were validated, as total absence of therapeutic action of solution C in all test subjects ruled out the presence of any placebo reactors and thus augmented and strengthened the results on the comparative values of solutions A and B. One patient reported B as the best solution but inferior to 0.25 per cent phenylephrine. Another All the rest preferred solution patient liked B best but pret’errcd naphazoline. B to any previously locally used nasal medication for the relief of blockage. Requests are persistently repeated hr\; all patients who have used this preparation. The duration of action is from 4 to 8 hours in different subjects. There was no evidence obtained of rebound blockage in any patient. One of the patients had severe allergic cephalgia in addition to nasal blockage and one had vest,ibular disease with vertigo when nasal blockage was present. Both. these patients had cxccllent relief of either headache or vertigo with solution B, fair results with solution .4, and no relief from solution C.
