The success of this method may rely on you particular cat's age and temperament, but it may be worth trying my preferred method: train your cat to willingly drink from a syringe. I stumbled across this idea when I needed to medicate just one of two kittens, and the other one seemed curious about trying to drink from the syringe.
Start by dipping an otherwise empty syringe in something smelly/delicious that your cat likes. I use the liquid from a tuna can (a lot of tuna isn't particularly good for cats, but it is safe to give in small amounts as a 'high value' treat), you could also use the "juice" from a can of with-gravy-style cat food if you and your cat prefer.
Let your cat approach at his own pace, and if he sniffs or licks the syringe, give praise and an additional small treat. Then try getting him to let you put a drop of the treat-substance into his mouth. Work up to putting an amount of treat-substance close to a medicine-dose amount into his mouth. The next step is (if you cat doesn't currently need any liquid meds) for him to drink plain water from the syringe, followed by praise and a treat. If your cat does need meds when you get to this point, you should skip the water and go on to giving medicine at this point. When you are done the course of medication, it's a good idea to periodically reinforce the trained behavior with tuna water, or plain water and then a treat, so they remember what the syringe thing is all about.
When my cat does need meds, I draw up the proper amount in the syringe, and then draw in a bit of the tuna water after, so it's the first thing they taste.
You might find it helpful to designate a specific place and time to take medicine so it becomes a normal part of your cat's routine. Once it becomes a normal thing that happens on a predictable cadence, it will be less stressful for your cat, and you may even find him already standing in the designated area when medication time comes, much as he would at mealtime.
