๐ Histamine,stimulates the secretion of pepsin.
๐ Histamine is a potent vasodilator . lt contracts the smooth muscles in the bronchi.
๐ Synthetic drugs brompheniramina ( Dimetapp) & terfenadine ( Seldane), act as antihistamines.
๐ Antiallergic & antacid drugs work on different receptors.
๐ Tranquilizer & analgesics are neurologically active drugs.
๐ Noradrenaline plays a role in mood changes.
๐ Chlordiazepoxide & meprobamate,are sutable for relieving tension.
๐ Equanil is used in controlling depression & hypertension.
๐ Barbiturates are hypnotic.
