Binding of the drug provides the stimulus for the release of histamine and other mediators. In the most severe form, a lifethreatening anaphylactic shock develops, accompanied by hypotension, bronchospasm (asthma attack), laryngeal edema, urticaria, stimulation of gut musculature, and spontaneous bowel movements.
Finally, nifedipine may be useful in chronic stable, or in variant angina (5–20 mg, capsule to be bitten and the contents swallowed). For sustained daytime angina prophylaxis, nitrates are of limited value because “nitrate pauses” of about 12 h are appropriate if nitrate tolerance is to be avoided.

 

The effectiveness of such indirect sympathomimetics diminishes or disappears (tachyphylaxis) when vesicular stores of NE close to the axolemma are depleted. Indirect sympathomimetics can penetrate the blood-brain barrier and evoke such CNS effects as a feeling of well-being, enhanced physical activity and mood (euphoria), and decreased sense of hunger or fatigue.
Purine (cell nuclei)-rich foods should be avoided, e. g. , organ meats. Milk, dairy products, and eggs are low in purines and are recommended. Coffee and tea are permitted since the methylxanthine caffeine does not enter purine metabolism. Uricostatics decrease urate production.
