Antihistamines also can be used on an as needed basis for those who experience occasional symptoms or symptoms triggered by exposure to certain irritants such as animal hair, plants, medications, and food products.

Some antihistamines also may be used occasionally to help with sleep.

Most antihistamines also have additional mechanisms of action that can counteract the sedation.

Dose is very important, because an antihistamine is not just an antihistamine, it will have varying binding affinities for other receptors and you want a dose that gives you a decent amount of histamine antagonism yet little activation of other receptors that are stimulating.

Is probably the most readily available sedating antihistamine.

It is a common ingredient in over-the-counter (OTC) preparations for sleep, such as Tylenol (acetaminophen) PM -- the PM part is diphenhydramine, the generic name for Benadryl.

Just wondering if someone could supply some binding affinity charts to this thread. I think dopamine blockade increases melatonin production or something?

It is not an addiction, it is tolerance to the medication.Quetiapine - antagonist at the following receptors: α1-adrenergic (IC50 = 94n M) α2-adrenergic (IC50 = 271n M) D1 (IC50 = 1268n M) D2 (IC50 = 329n M) D3 (unspecified) D4 (unspecified) H1 (IC50 = 30n M) 5-HT1A (IC50 = 717n M) 5-HT2A (IC50 = 148n M) 5-HT2C (unspecified) 5-HT7 (unspecified) m ACh receptor (IC50 = 5000n M) antagonist Mirtazepine - antagonist at the following receptors: α1-adrenergic (Ki = 608 n M? I have tried diphenhydramine, promethazine, and seroquel.) α2C-adrenergic (Ki = 18 n M) α2A-adrenergic (Ki = 20 n M) α2B-adrenergic (unspecified, likely similar to α2A/α2B-adrenergic) D1 (Ki = 4,167n M) D2 (Ki = 1,460n M) D3 (Ki = 5,723n M) D4 (Ki = 25n M) H1 (Ki = 5.1 n M) 5-HT1A (Ki=18n M; IC50=1,000n M) 5-HT2A (Ki = 69 n M) 5-HT2B (unspecified, ~20-fold lower than for 5-HT2A/2C) 5-HT2C (Ki = 39 n M) 5-HT3 (unspecified, likely similar to 5-HT2A/2C) 5-HT7 (Ki = 265 n M) m ACh receptors (Ki = 794 n M? Out of those, seroquel was by far the most sedating, with promethazine coming in second.Anyway I'd like to know which of them (regardless as their branding as 'antihistamines') has the strongest affiliations with these receptors known for producing hypnotic properties.From what I can tell I think the list beginning with the strongest goes something like this: Quetiapine (seroquel) Mirtazipine (remeron) (from experience) Hydrazine Promethazine (from inference from the internet's experience) --------- Anything else I'm missing here?
