1) Mecanism? Not sure but I think thiazides may increase lithium toxicity by Li retention.
Thiazides will also increase the risk of digoxin toxicity, due to the hypokalaemia.
4) Phenytoin? dont know

1]Loop diuretics: May decrease the renal excretion of lithium, leading to toxicity...Thiazide diuretics: May increase serum lithium concentration via sodium depletion and decreased lithium clearance; a lithium dose reduction of 50% is commonly recommended.
2]patients with congestive heart failure, have renal function that is strongly dependent on prostaglandin-mediated blood flow. NSAIDs can inhibit this process and result in further decline. When NSAID therapy diminishes renal function, it can lead to fluid retention, hyperkalemia, and congestive heart failure.
3]tincture of opium
4]phenytoin-Rarely seen effects: SLE-like syndrome, lymphadenopathy, hepatitis, Stevens-Johnson syndrome, blood dyscrasias, dyskinesias, pseudolymphoma, lymphoma, venous irritation and pain, coarsening of facial features, hypertrichosis
5]nicotinicacid and pyrazinamide
