Tóm tắt

Nhiều biện pháp về việc hút thuốc lá, tác động chủ quan và tác động sinh lý đã được thu thập trong các buổi thử nghiệm kéo dài 90 phút trên các tình nguyện viên bình thường. Trước khi tiến hành thử nghiệm, các đối tượng đã nhận liều uống mecamylamine (2.5, 5.0, 10, 20 mg) hoặc giả dược. Mỗi liều và giả dược được cung cấp ba lần trong một chuỗi ngẫu nhiên. Mecamylamine đã tăng nhiều biện pháp về việc hút thuốc lá, bao gồm số lượng thuốc lá, số lần hút mỗi điếu thuốc và mức độ carbon monoxide trong không khí thở ra. Mecamylamine cũng tạo ra những giảm nhẹ, có liên quan đến liều lượng, trong huyết áp đứng và tăng nhịp tim đứng. Các tác động chủ quan do mecamylamine tạo ra không đặc trưng cho các loại thuốc tác động tâm lý. Mecamylamine dường như đã làm tăng việc hút thuốc lá bằng cách giảm mức liều hiệu quả của nicotine có sẵn từ việc hút thuốc lá.
