Specific codes in ICD-10 are unique alphanumeric designations used to identify and categorize diseases, disorders, and conditions. They consist of 3-5 characters, including both letters and numbers, that provide a high level of detail and specificity.

| Active Ingredient | Description | |
|---|---|---|
| Isoprenaline |
Isoprenaline is a potent non selective beta-adrenergic agonist with low affinity for alphaadrenergic receptors. Isoprenaline acts primarily on the heart and on smooth muscle of bronchi, skeletal muscle vasculature and the gastrointestinal tract. |
|
| Propranolol |
Propranolol is a competitive antagonist at both beta, and beta2-adrenoceptor, but has membrane stabilising activity at concentrations exceeding 1-3mg/litre, though such concentrations are rarely achieved during oral therapy. Competitive beta-blockade has been demonstrated in man by a parallel shift to the right in the dose-heart rate response curve to beta-agonists such as isoprenaline. |
