A pharmacist who has no role in this trial, allocates a 4 digit random code to each envelope using the random function on a scientific calculator, and each patient gets one envelope. Therefore, allocation of patients to Sumatriptan or placebo groups is accomplished by simple randomization technique, Blinding description: A pharmacist who has no part in the study, conceals the Sumatriptan and placebo tablets in sealed envelopes and generates a unique random 4 digit number for each envelope. The fact that each 4 digit number shows a Sumatriptan or placebo containing envelope is kept in an allocation chart. The pharmacist keeps the allocation chart sealed till the end of trial. Therefore, random allocation and allocation concealment is achieved for both the patients as well as the operators, examiners, surgeons and clinicians. 3 post-operative pain after rhinoplasty.
