Please be aware that in vitro experiments demonstrate the effects of a drug or compound in a controlled environment outside of a living organism, which does not account for the complex interactions that occur in vivo. Often, findings from in vitro studies do not directly correlate with in vivo outcomes.
For example, nicotine is rapidly metabolized into its primary metabolite, cotinine, in the human body, with a half-life of approximately 2 hours. Thus, if you aim to achieve a particular clinical effect of nicotine on specific cells in the body at a desired concentration, it is crucial to consider its rapid metabolism and the subsequent downstream effects of this process.
Really it depends on what concentrations have a clinical effect, and how long the cells need exposure.
1. Pharmacokinetics:
Nicotine Gum: Delivers nicotine quickly through the lining of the mouth, causing rapid but short-lived increases in nicotine concentration. This leads to transient spikes in cellular nicotine levels, with periods of higher concentration followed by a rapid decline.
Nicotine Patch: Provides a slow and steady release of nicotine through the skin, resulting in a stable and sustained increase in nicotine levels in the bloodstream. This steady delivery maintains a consistent cellular nicotine concentration over a prolonged period.
2. Cellular Implications:
Nicotine Gum: The intermittent spikes in nicotine levels prevent prolonged receptor activation, reducing the risk of long-term receptor desensitization and cellular adaptation, You end up with peaks of high concentrations.
Nicotine Patch: Continuous exposure to nicotine leads to sustained receptor activation, which can result in receptor desensitization or downregulation over time due to prolonged cellular exposure. You end up with steady but lower concentrations.

I wonder if the gum is any better/worse
