Comparison of melatonin, gabapentin and dranabinol in pain control of patients after hip fracture repair surgery. 2025-10-17 anticipated 120 Complete https://irct.ir/trial/86608 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Participants will be assigned to three intervention groups in order of arrival and based on a randomization sequence that will be generated in advance. This sequence is unpredictable and its arrangement is completely random. A block randomization method with blocks of 9 will be used to allocate the samples. Thus, using the block random number generation software, a randomization sequence proportional to the required sample size will be generated for the three groups. Initially, all the cases in which the 3 letters A, B, and C can be arranged together in a block of 9 are performed. Then, a block is randomly selected from the blocks by placement, and the arrangement pattern in that block will be used to allocate the participants. Then this block is placed in the main container and another block will be selected again. All these steps will be performed with a software called Sealed Envelope. Concealment will also be observed using this method. The concept of concealment is to make the assignment of individuals to groups unpredictable. In fact, the researcher will not be able to predict which group the next person will be placed in, Blinding description: This study will be conducted in a double‑blind design. None of the patients will be aware of the type of medication they receive. The drugs will be administered by the anesthesiologist. Each patient’s medication will be placed in a container and handed to them, without the patient knowing its contents. The assigned intern responsible for outcome recording will also be unaware of the group allocation; patients will be evaluated based on their medical record number, and the collected data will be delivered to the supervising attending physician. 3 Femur fracture repair surgery. Intervention 1: Intervention group: Patients in this group will receive two 3‑mg melatonin tablets (Razak Pharmaceutical Co.), totaling 6 mg, one hour prior to surgery. Intervention 2: Intervention group: Patients in the gabapentin group will receive two 300‑mg gabapentin capsules (Actoverco Pharmaceutical Co.) one hour prior to surgery. Intervention 3: Intervention group: Patients in the dronabinol group will receive two 2.5‑mg dronabinol capsules (Roxane, Columbus, OH) one hour prior to surgery.
